Zygomatic Implants vs Sinus Lift and Grafting: Two Routes for a Resorbed Upper Jaw Compared

The scan is up on the screen, and the surgeon traces a thin grey line with the tip of a pen. That line is what remains of the back of the upper jaw. Below it, a dark hollow: the sinus, which has quietly expanded into the space where tooth roots used to be. The patient has worn a denture for eleven years and came in asking about implants. The answer is not no. The answer is a question: which of two very different routes?

This is the moment many people first hear the phrase zygomatic implants vs sinus lift. One route rebuilds the bone and waits for it to mature. The other skips the missing bone entirely and anchors into the cheekbone, a few centimeters higher. Both are established, both carry trade-offs, and both are surrounded by confident marketing that outruns the evidence.

What follows is an attempt to lay the two side by side honestly: what each involves, who tends to be offered which, what the following weeks look like, and which questions are worth asking before anyone picks up a drill.

Why does the back of the upper jaw lose bone so quickly?

Bone behaves like muscle in one respect: it stays strong where it is loaded and shrinks where it is not. A tooth root presses on the jawbone thousands of times a day during chewing, and that pressure tells the bone to keep renewing itself. Remove the tooth, and the signal stops. The ridge begins to narrow and lose height within months, a process clinicians call resorption. Resorption simply means the body breaking down and reabsorbing bone it no longer thinks it needs.

The upper back jaw has a second problem that the lower jaw does not. Sitting directly above the molar roots is the maxillary sinus, an air-filled cavity behind the cheek. When the teeth go, the floor of that sinus tends to drift downward into the vacated space. Dentists call this pneumatization: the sinus enlarging at the expense of bone. The ridge thins from below as the sinus expands from above, and the two meet in the middle.

Upper jaw bone is also naturally less dense than lower jaw bone, more like a honeycomb than a plank. That matters because a standard dental implant, a titanium post placed into the jaw to support a replacement tooth, needs a certain depth and width of bone to fuse securely. The Mayo Clinic notes that people without adequate bone are often offered grafting before implants can proceed, and that this step can add months to the overall timeline.

Long-term denture wear accelerates everything. A denture rests on the gum and transmits pressure to the ridge in a way the bone interprets as a reason to shrink further, not grow. So the person who has managed on a denture for a decade often arrives with the least bone of all, and the most to think about.

What is a sinus lift in dentistry, and how does grafting rebuild bone?

A sinus lift, also called sinus augmentation, is a surgical procedure that raises the floor of the maxillary sinus and fills the newly created space with graft material so that bone can form there. The aim is to restore enough height beneath the sinus for ordinary implants to be placed.

The sinus is lined by a thin membrane, roughly the thickness of a sheet of paper, called the Schneiderian membrane. The surgeon’s task is to lift this lining gently away from the bone without tearing it. There are two common approaches. In the lateral window technique, a small opening is made in the side wall of the sinus above the molars, the membrane is lifted, and graft material is packed beneath it. In the crestal or osteotome technique, the surgeon works from the implant site itself, tapping upward through the ridge to raise the membrane by a few millimeters. The lateral approach suits larger gains; the crestal approach suits smaller ones.

Graft material may be the patient’s own bone, processed donor bone, animal-derived bone mineral, or a synthetic substitute. Each acts as a scaffold. Over the following months the body grows new bone through and around it, gradually replacing the scaffold with living tissue. The Cleveland Clinic describes this healing window as typically several months, often quoted as roughly four to twelve, before the site is ready for implants.

Where the remaining ridge is also too thin or too short in other directions, a separate bone graft onto the ridge may be added, sometimes in the same session. Each layer of grafting adds predictability for the eventual implant, and each adds healing time. That trade between time and foundation is the heart of the comparison.

How do zygomatic implants work when there is almost no jawbone left?

The zygoma is the cheekbone, the dense arch you can feel beneath your eye. Zygomatic implants are extra-long titanium fixtures, often several times the length of a conventional implant, that start at the ridge of the upper jaw, pass alongside or through the sinus, and anchor their tip in the cheekbone. Instead of rebuilding the lost foundation, they reach past it to a foundation that still exists.

The cheekbone is well suited to this role. It is thick cortical bone, the hard outer type, and it does not resorb after tooth loss because it never held teeth in the first place. A fixture secured there can be very stable from the moment it is placed. That stability is why many surgical protocols allow a fixed temporary bridge to be attached within the same visit or shortly after, rather than months later. Whether that is appropriate for a particular person is a decision for the surgical team based on how firmly the implants seat.

Typically two zygomatic implants are placed, one on each side, and combined with conventional implants toward the front of the jaw where bone is usually better preserved. When the front of the jaw is also severely resorbed, some protocols use four zygomatic implants with no conventional ones. The replacement teeth take the form of a full-arch bridge screwed onto the implants, not individual crowns.

The angle of placement matters. The fixture emerges on the palate side of the ridge in older techniques, which some people find bulky against the tongue. Newer trajectories keep the emergence closer to where natural teeth sat. Three-dimensional imaging, usually a cone-beam CT scan, is standard planning for this surgery because the path runs close to the sinus, the orbit and the facial nerves.

Zygomatic implants vs sinus lift: what actually happens on the day

Picture two operating rooms. In the first, a sinus lift is under way. Local anesthesia is common, often with sedation. The surgeon makes an incision in the gum above the back teeth, exposes the sinus wall, and creates a small window. Working with rounded instruments, they ease the membrane upward and introduce the graft. A collagen barrier may be laid over the window, and the gum is closed with stitches. If the ridge still has reasonable height, an implant may be placed in the same session; if not, the site is left to heal and implants follow months later. The procedure for one side commonly takes around an hour to ninety minutes, though timings vary with complexity and are not a promise.

In the second room, zygomatic implant surgery is longer and more involved. General anesthesia or deep sedation is usual because the fixtures travel a greater distance through the face. The gum is reflected widely to expose the ridge and the lower part of the cheekbone. Guided by the pre-operative scan, and sometimes by a surgical template or navigation, the surgeon prepares a channel from the ridge to the zygoma and seats the long fixture. Conventional implants in the front are placed in the same session. Impressions or digital scans may be taken immediately so that a provisional bridge can be fitted within hours or days.

The contrast is one of philosophy as much as technique. The sinus lift accepts a longer road in exchange for implants in rebuilt, native-feeling bone. The zygomatic route accepts a bigger single operation in exchange for skipping the graft and, often, the waiting. Both are performed by oral and maxillofacial surgeons or periodontists with specific training, and both begin with the same imaging.

Who is each route usually for, and who is usually asked to wait?

The single most important variable is how much bone remains beneath the sinus. Where a few millimeters of ridge height persist, a sinus lift is the conventional first choice because it keeps implants in the natural arch and preserves future options. Where height has fallen close to zero across the whole back jaw, or where previous grafts have failed or resorbed, zygomatic implants are more often discussed. People who have lost upper jaw bone to tumor surgery, severe trauma or a cleft are also frequent candidates for the zygomatic route, since no amount of grafting will easily rebuild what was removed.

Appetite for time matters too. Someone prepared to wear a denture through months of graft healing may prefer the sinus lift. Someone who cannot tolerate a removable denture, for medical or practical reasons, may lean toward a route that offers fixed teeth sooner. That is a legitimate factor, not a vanity.

Both routes share caution lists. Uncontrolled diabetes, heavy smoking, active gum disease, chronic sinus infection, and certain medicines that affect bone turnover, such as some used for osteoporosis or cancer, all raise the risk of poor healing or infection. The Mayo Clinic lists these among the reasons a team may ask a person to stabilize their health first. Smoking in particular is strongly linked to implant failure, and many surgeons ask for a period of cessation before and after surgery.

A history of sinus disease weighs more heavily on the zygomatic decision, because the fixtures run alongside the sinus for life. An ear, nose and throat assessment is sometimes requested before proceeding. Those with very thin cheekbones on imaging may be guided back toward grafting. The decision rests with the treating team, who can see the anatomy the patient cannot.

Zygomatic implants vs sinus lift and grafting at a glance

Comparison tables flatten nuance, but they also make the structural differences visible at a glance. Everything below describes typical patterns reported by mainstream sources; an individual plan may differ.

Feature	Sinus lift with grafting	Zygomatic implants
Where the implant anchors	Rebuilt bone in the upper jaw	Cheekbone (zygoma), bypassing the jaw deficit
Number of surgical stages	Often two or three, graft then implants then teeth	Often one main surgery, sometimes with same-day provisional bridge
Typical healing before final teeth	Several months of graft maturation plus implant integration	Provisional teeth may be fitted early; final bridge after integration
Anesthesia commonly used	Local, often with sedation	General or deep sedation
Main structure at risk	Sinus membrane during lifting	Sinus lining, orbit and facial soft tissue along the implant path
Most discussed complication	Membrane tear, graft infection or loss	Sinusitis, soft tissue recession around the fixture
Type of replacement teeth	Single crowns, bridges or full arch	Almost always a full-arch fixed bridge
Suitable when bone is	Reduced but still present beneath the sinus	Severely resorbed or surgically absent

Two rows deserve emphasis. The first is the type of teeth. A sinus lift opens the door to replacing one or two missing molars, or an entire arch. Zygomatic implants are essentially a full-arch solution; they are rarely used to replace a single tooth. The second is the anesthesia row, which tells you something about the scale of each operation and the recovery that follows.

What the table cannot show is reversibility. A failed graft can usually be redone or abandoned without permanent change. A zygomatic implant, once placed, has altered the cheekbone, and its removal is a significant procedure in its own right.

How long do zygomatic implants last? What the evidence actually shows

This is the question people most want answered with a number, and it is the one where honesty matters most. Zygomatic implants were introduced in the late twentieth century, so the longest published follow-up stretches to a few decades at most, in relatively small groups of patients. Systematic reviews pooling these studies generally report fixture survival comparable to conventional implants over follow-up periods of several years, with loss most often occurring early, before integration is complete. Beyond that qualitative picture, specific percentages vary widely between reviews depending on which studies were included and how success was defined, so no single figure can be quoted responsibly here.

Survival is also not the same as freedom from problems. An implant can remain firmly anchored while the sinus beside it becomes chronically inflamed, or while the gum around its neck recedes and exposes metal. Reviews consistently name sinusitis as the most frequently reported complication of the zygomatic route, which is why the sinus health conversation before surgery is so central.

The MedlinePlus overview of dental implants notes that implants generally can last many years with good care, and that failure is more likely in smokers and in people with poorly controlled gum disease or diabetes. Those modifiers apply with equal force to zygomatic fixtures. The bridge attached to the implants is a separate matter: acrylic and composite teeth wear and may need replacement or relining well before the fixtures themselves show any trouble.

Perhaps the fairest way to frame longevity is this: the cheekbone anchor is stable, the published record is encouraging but still maturing, and the outcome for any one person depends more on daily cleaning, regular review and not smoking than on the type of implant chosen.

Sinus lift vs bone graft: are they the same procedure?

The two terms are often used as if they were interchangeable. They are not. A sinus lift is one specific kind of bone graft, defined by location: it adds bone beneath the floor of the sinus to gain height. Bone grafting in general is a broader category that includes adding width to a thin ridge, filling a fresh extraction socket to limit shrinkage, or rebuilding a larger defect with a block of bone taken from elsewhere.

The Cleveland Clinic separates these clearly. Ridge augmentation builds the jaw outward; socket preservation protects the shape of the bone immediately after a tooth is removed; a sinus lift builds upward into the sinus. Several of these may be combined in one treatment plan. A person with a short, narrow ridge in the upper back jaw might need both a lift for height and a lateral graft for width before a standard implant will fit.

Graft sources also cut across all these procedures. Autograft means the patient’s own bone, usually harvested from the chin, the back of the lower jaw or occasionally the hip. Allograft is processed human donor bone. Xenograft is animal-derived mineral, typically bovine, with the organic material removed. Alloplast is fully synthetic. Each has a different pattern of being replaced by living bone, and surgeons choose based on the size of the defect and how much structural support the graft must provide while new bone forms.

Why does the distinction matter to a patient? Because the healing timeline, the risks and the second surgery depend on which grafts are planned. Asking whether a proposed sinus lift will be the only graft, or one of several, clarifies the real length of the road ahead and how it compares with the single-stage zygomatic alternative.

Zygomatic implants vs pterygoid implants: what is the difference?

Both are graftless strategies for the back of the upper jaw, which is why they get confused. The difference lies in what the implant tip grips. A zygomatic implant anchors in the cheekbone, outside and above the sinus. A pterygoid implant is a long conventional-style fixture angled backward from the molar region into the pterygoid plates, a dense pillar of bone behind the upper jaw where it meets the base of the skull.

The pterygoid region is useful because, like the cheekbone, it does not resorb after tooth loss. Anchoring there allows a fixed bridge to extend further back without a long unsupported section hanging behind the last implant, a design known as a cantilever that places extra stress on the whole structure. Pterygoid implants are placed from inside the mouth through the ridge, without entering the sinus, so sinusitis is less of a concern than with the zygomatic path.

Why not use pterygoid implants for everyone, then? Access is the limitation. The angle required is steep, visibility is poor at the very back of the mouth, and the bone volume in the pterygoid plates varies between individuals. Pterygoid fixtures also deal only with the rear of the arch; they do not solve a deficit beneath the sinus in the premolar area, which is where the zygomatic implant earns its place.

In practice the two are often combined. A full-arch plan for a severely resorbed upper jaw might include conventional implants in the front, zygomatic implants in the middle and pterygoid implants at the back, each exploiting whatever bone remains. The choice is dictated by imaging, not preference. A team that mentions pterygoid implants is usually trying to reduce the number of zygomatic fixtures, or to improve support for the back of the bridge.

Which is more painful, a bone graft or an implant?

Counterintuitively, implant placement on its own is often described by patients as less uncomfortable than the grafting that precedes it. Implant surgery involves preparing a channel in bone, which has few pain-sensing nerves, and the surrounding gum heals quickly. Grafting usually means lifting a larger flap of gum, working near the sinus membrane, and sometimes harvesting bone from a second site. Two wounds hurt more than one, and the donor site in the chin or lower jaw can ache for longer than the recipient site.

Sinus lifts in particular produce a distinctive post-operative picture: a feeling of pressure or fullness in the cheek, mild nasal congestion, and sometimes slight bloody discharge from the nose for a few days. The Cleveland Clinic describes soreness and swelling settling over roughly a week to ten days, with the sensation of fullness fading as the membrane heals. Sneezing with the mouth open and avoiding nose-blowing are standard instructions, because a surge of air pressure can disturb the fresh graft.

Zygomatic implant surgery sits at the more intensive end. Because the operation is longer and the gum is reflected widely up toward the cheekbone, facial swelling and bruising are usually more pronounced, sometimes extending toward the eye. Numbness or altered sensation in the cheek can occur while nerves recover. Most people describe discomfort peaking around the second or third day and easing steadily thereafter, though recovery of normal facial sensation and comfort while chewing takes longer.

Pain control for all three procedures typically relies on ordinary over-the-counter analgesics, with short prescriptions where needed. Decisions about which medicines, and for how long, belong to the surgical team. What people can control themselves is rest, cold compresses in the first day or two, and a soft diet.

What do the days and weeks after each procedure usually look like?

After a sinus lift, the first week is about protecting the membrane. Swelling peaks within two to three days and subsides over the following week. Stitches, if not dissolvable, come out at around one to two weeks. The surgeon will usually review the site at this point and again at intervals while the graft matures. Nothing much happens to the patient during the long middle stretch, which is the hard part psychologically: a denture, or a gap, for months while bone quietly forms. A follow-up scan then confirms whether there is enough new bone for implants. Once implants are placed, a further period of integration, during which the bone fuses to the titanium surface, is needed before final teeth. The Mayo Clinic describes the whole process from first consultation to final crown as commonly taking many months.

After zygomatic implant surgery, the first days are more intense but the arc is shorter. Facial swelling and bruising are expected and may take two weeks to fade. A provisional bridge, where fitted, allows the person to leave with fixed teeth but comes with strict instructions: soft foods only, no biting into anything firm, and meticulous cleaning around the implant necks. The temporary bridge is reviewed frequently in the first month. Integration still has to happen; a final, stronger bridge is usually made once the team is confident the fixtures are stable, often a few months later.

Both routes converge on the same long-term rhythm. Professional cleaning and review at intervals set by the team, home cleaning with interdental brushes or water irrigation around the bridge, and prompt reporting of any new sinus symptoms, looseness or bleeding. The surgery is a chapter; the maintenance is the book.

What are the risks of each route, in neutral terms?

Every surgical procedure carries general risks: bleeding, infection, swelling, bruising and reaction to anesthesia. Beyond those, each route has a signature set of complications worth understanding before consent.

For sinus lifts, the most common intra-operative event is a tear in the sinus membrane. Small perforations are usually repaired with a collagen patch and the procedure continues; larger tears may mean abandoning the lift and returning after healing. Graft infection can occur in the weeks after surgery and may require removal of the material. Occasionally graft particles migrate into the sinus, causing inflammation. Sinusitis after a lift is less frequent than after zygomatic placement but does occur, particularly in those with pre-existing sinus disease. The MedlinePlus overview of sinusitis describes the symptoms to watch for: facial pressure, thick nasal discharge and reduced sense of smell persisting beyond a cold.

For zygomatic implants, sinusitis is the headline complication, reported in reviews as the most frequent problem, sometimes appearing years after placement. Because the fixture passes near the sinus for its full length, a breakdown in the seal between mouth and sinus can create a persistent communication, known as an oroantral fistula, which may need surgical closure. Soft tissue recession around the implant neck can expose the fixture on the palate side. Rarer but serious events include injury to the orbit, the bony socket around the eye, and penetration into the nasal cavity or temporal fossa. These risks are why three-dimensional planning and specialist training are not optional.

Both routes share the risk of implant failure, where the bone does not integrate with the titanium. Early failure is more common than late failure, and smoking, uncontrolled diabetes and poor oral hygiene raise the odds for either approach. Neither route is risk-free, and neither is reckless; they simply carry different risks in different places.

What people often get wrong about zygomatic implants and sinus lifts

The first myth is that one approach beats the other every time. Headlines promising that zygomatic implants have made grafting obsolete, or that grafting is always safer, both misread the evidence. Published reviews show each route performing well in the patients it was designed for. A person with moderate bone loss who receives zygomatic implants has accepted a larger operation than needed; a person with no bone who undergoes repeated failing grafts has accepted years of surgery that may never reach the goal.

The second myth is that a sinus lift damages the sinus. The sinus lining is lifted, not removed, and the sinus continues to function. Chronic problems are the exception, and most arise where sinus disease was already present.

The third is that zygomatic implants are implants in the face rather than the mouth. The fixture is placed from inside the mouth and emerges inside the mouth. Nothing is visible externally once swelling settles. The cheekbone is simply where it ends, not where it begins.

Fourth, people assume the temporary bridge fitted on the day of zygomatic surgery is the final result. It is a provisional, often acrylic, designed to be lighter and to be replaced. The definitive bridge follows integration.

Fifth, that implants, once placed, are maintenance-free. The NHS guidance on dental treatments is clear that implants need the same daily cleaning and professional review as natural teeth, and that gum disease around implants, called peri-implantitis, can lead to bone loss and failure.

Finally, that pain predicts success. A smooth, comfortable recovery is welcome but tells you nothing about whether the bone has integrated. Only time, clinical checks and imaging do that.

Questions to ask your care team before choosing a route

A good consultation leaves you knowing not just what is proposed but why the alternative was set aside. These questions tend to open that conversation.

• How much bone remains beneath my sinuses on the scan, and at what point would you have recommended the other route instead?
• If grafting is proposed, how many separate surgical stages are expected, and what is the realistic total time before final teeth?
• If zygomatic implants are proposed, how many will be placed, and will conventional or pterygoid implants be combined with them?
• Have you assessed my sinus health, and would an ear, nose and throat opinion change the plan?
• What would happen if the graft fails to mature, or if a zygomatic fixture does not integrate? What is the fallback?
• What will my teeth be during healing: a denture, a provisional bridge, or nothing?
• What type of anesthesia will be used, and who will provide it?
• What are the specific risks you see for my anatomy, and how would each be managed?
• How often will I need review in the first year, and what does long-term maintenance involve?
• What changes to smoking, blood sugar control or current medicines should I discuss with my physician beforehand?

Bring someone with you if you can. Two sets of ears retain more than one, and the choice between a slow rebuild and a single larger operation is easier to weigh at home than in the chair. Ask for the written treatment plan, including the sequence of stages, before agreeing to anything. A team confident in its recommendation will welcome the questions.

When to call your doctor after a sinus lift or zygomatic implant surgery

Some discomfort, swelling and minor bleeding are expected after either procedure. Certain signs are not, and they warrant a same-day call to the surgical team or, out of hours, emergency care.

Call urgently if you notice bleeding that soaks through gauze and does not slow with firm pressure after half an hour; swelling that keeps increasing after the third day rather than settling; fever above the level your team specified, or chills; severe pain that is worsening despite the prescribed plan; or pus, a foul taste, or a bad smell from the surgical site.

After a sinus lift or zygomatic surgery specifically, report any sensation of air passing between your mouth and nose when drinking, liquid escaping through the nose, graft particles or small granules appearing in nasal discharge, persistent one-sided nasal blockage, or facial pressure and thick discoloured discharge lasting more than a week. These may indicate a communication with the sinus or developing sinusitis, both of which are more easily managed early.

Seek emergency care immediately for difficulty breathing or swallowing, swelling that closes the eye or involves the throat, sudden changes in vision, or numbness that spreads rather than fades.

In the months and years that follow, make an appointment promptly if an implant or bridge feels loose, if the gum around an implant bleeds easily or recedes to expose metal, or if sinus symptoms begin for the first time. None of these mean the treatment has failed, but all deserve assessment rather than waiting. Your treating team knows the anatomy of your surgery; they are the right first call.

Frequently asked questions

What is a sinus lift in dentistry?

A sinus lift is a surgical procedure that raises the floor of the maxillary sinus and places graft material beneath it so new bone can grow, creating enough height for dental implants in the upper back jaw. The sinus lining is lifted, not removed, and the Cleveland Clinic notes the graft typically matures over several months before implants are placed.

How long do zygomatic implants last?

Published systematic reviews report survival of zygomatic implants comparable to conventional implants over follow-up periods of several years, with most losses occurring early. The longest records span a few decades in small groups. Longevity depends heavily on sinus health, daily cleaning, regular review and not smoking rather than on the fixture alone. The attached bridge usually needs renewal before the implants do.

What is the difference between zygomatic implants and pterygoid implants?

Zygomatic implants anchor in the cheekbone, running alongside the sinus; pterygoid implants angle backward from the molar area into the pterygoid plates behind the upper jaw, avoiding the sinus entirely. Pterygoid fixtures support the back of a bridge but cannot replace missing bone beneath the sinus, so the two are often combined in a single full-arch plan.

Which is more painful, a bone graft or an implant?

Grafting is often reported as more uncomfortable than implant placement alone, because it involves a larger gum flap, work near the sinus membrane and sometimes a second donor site. Zygomatic surgery produces more facial swelling than either because of its scale. Discomfort for all three typically peaks within two to three days and then eases steadily.

Is a sinus lift vs bone graft the same decision?

No. A sinus lift is one type of bone graft, defined by its location beneath the sinus. Other grafts add width to a thin ridge or protect a fresh extraction socket. A treatment plan may include one, several or none, and the number of grafts planned determines how the timeline compares with a single-stage zygomatic approach.

Can zygomatic implants replace a single missing tooth?

Almost never. Zygomatic implants are designed as anchors for a full-arch fixed bridge in a severely resorbed upper jaw. For one or two missing molars, a sinus lift followed by standard implants, or a short implant where bone allows, is the conventional approach. The surgical scale of zygomatic placement is not justified for a single tooth.

Will a sinus lift affect my breathing or cause sinus problems?

The sinus continues to function after a lift because its lining is preserved. Temporary congestion and a feeling of fullness are common for about a week. Persistent sinusitis is uncommon and arises mostly in people with pre-existing sinus disease, which is why surgeons ask about sinus history and sometimes request an ear, nose and throat assessment beforehand.

Do zygomatic implants show on the face?

No. The fixtures are placed from inside the mouth and emerge inside the mouth; the cheekbone is where they end, not where they start. Swelling and bruising near the cheek and eye are expected for about two weeks after surgery and then fade. Once healed, nothing is visible externally, and the bridge sits where natural teeth did.

Who is usually asked to wait before either procedure?

People with uncontrolled diabetes, active gum disease, chronic sinus infection, or heavy smoking are commonly asked to address these first, as the Mayo Clinic lists them among factors that impair healing and raise implant failure risk. Those taking medicines that affect bone turnover should discuss timing with both their physician and the surgical team before any plan proceeds.

What happens if a graft or a zygomatic implant fails?

A failed graft can usually be allowed to heal and either repeated or abandoned in favor of another route, including zygomatic implants. A zygomatic fixture that fails to integrate requires removal, which is a significant procedure, and the team then reassesses remaining bone. Asking about the fallback plan for each route before surgery is a reasonable part of consent.
