The Zygomatic Implant Procedure, Step by Step

Zygomatic implant surgery is a single operation, usually under general anaesthesia, in which extra-long implants are placed through or alongside the maxillary sinus into the cheekbone and a fixed temporary bridge is attached within days. It is genuine maxillofacial surgery, planned in three dimensions. This guide walks through every stage in the order you will experience it, so that nothing on the day is a surprise.

What makes this operation different

Standard implants are placed into the jaw. A zygomatic implant is much longer and is angled upwards and backwards so that its tip anchors in the zygomatic bone — the cheekbone — passing alongside or through the maxillary sinus on the way. That single difference changes the shape of treatment: there is no bone graft to heal first, so stages that would normally be spread over a year compress into one operation plus a healing wait.

It also means the surgery is planned and performed by clinicians with specific training in zygomatic anatomy, usually oral and maxillofacial surgeons rather than general implant dentists. The margin for error is small — the drill path runs close to the orbit (eye socket) and the sinus — which is why surgeons typically plan every implant digitally beforehand. For the underlying anatomy, start with the complete zygomatic implants guide.

What follows is the two-visit graftless pathway, the usual model for UK patients treated abroad. Timings are indicative and not yet confirmed in writing by the clinic, so treat them as typical rather than promised.

The full pathway, stage by stage

Eight stages, spread across roughly six months and two visits. Durations below are indicative and not yet confirmed in writing by the clinic.

  1. Stage 1

    Remote assessment and a written plan

    You send whatever imaging you already have — usually a panoramic X-ray, sometimes an earlier CBCT — with a medical history and current medication list. A surgeon reviews it and you receive a preliminary opinion, a proposed implant configuration and a written quote. This stage is remote and costs nothing at most clinics, and it remains a preliminary opinion only.

  2. Stage 2

    In-person consultation and 3D planning

    On arrival, a fresh CBCT is taken and the plan is confirmed or revised. Implant positions, lengths and angles are planned on the 3D data set, and the provisional bridge is designed alongside them. Blood tests and an anaesthetic review normally happen here too. Occasionally the scan shows something the flat X-ray hid and the plan changes — for example from a hybrid case to quad zygomatic implants. Ask how that would be handled, and priced, before you travel.

  3. Stage 3

    Anaesthesia and preparation

    Surgery can be carried out under local anaesthetic, under sedation, or under general anaesthesia. Which one is used is decided by you and your surgeon together, based on your health and the case. If sedation or general anaesthesia is planned you will be asked to fast beforehand, usually from midnight; under local anaesthetic no fasting is needed and the appointment follows the same protocol as ordinary dental treatment. Any remaining upper teeth that cannot be saved are extracted at the start of the same operation, so that extraction, implant placement and the provisional bridge all happen in one sitting.

  4. Stage 4

    Placing the implants — usually 2 to 4 hours

    The surgeon raises the gum to expose the front and side of the upper jaw, identifies the base of the cheekbone, and prepares the channel for each implant under direct vision. Each implant is inserted so that its tip engages dense cheekbone and its head emerges at the right position on the ridge for the bridge. In a hybrid case, standard implants are placed at the front in the same session. Most cases take around two to four hours; quad zygoma cases sit at the longer end.

  5. Stage 5

    Fixed provisional bridge within 24 to 72 hours

    Because cheekbone anchorage is immediately stable in most cases, the implants can usually be loaded straight away. An impression or digital scan is taken, and a fixed provisional bridge — commonly an acrylic and titanium hybrid — is screwed onto the implants within 24 to 72 hours. This is what people mean by "teeth in a day": fixed, not removable, but temporary.

  6. Stage 6

    Discharge checks before you fly home

    The first visit is typically five to seven days in total. Before discharge the bite is adjusted, hygiene around the new bridge is taught, and you are given written aftercare, medication and a direct contact route. Make sure you know exactly who to call, and how, once you are back in the UK.

  7. Stage 7

    Osseointegration — usually 4 to 6 months

    The bone remodels around each implant while you wear the provisional bridge and eat a softer diet. Follow-up during this phase is normally remote if you were treated abroad. Nobody can promise a healing time: smoking, diabetes, medication and bone quality all change it, and some cases are reviewed for longer.

  8. Stage 8

    Second visit for the final zirconia bridge

    A second trip of roughly five to seven days covers final impressions, a try-in, and delivery of the definitive bridge — usually monolithic zirconia, which is stronger and more stable in colour than the provisional. The bite is refined over a few appointments rather than one, and a maintenance and review schedule is agreed.

Where the implant actually sits

A standard implant stays within the jawbone. A zygomatic implant begins on the jaw ridge and travels up into the cheekbone, which is why it works when the jaw itself is too thin to hold anything.

Standard implant compared with a zygomatic implantSide view of the upper jaw. A standard implant is 8 to 15 millimetres and relies on the upper jawbone, which becomes too thin after bone loss. A zygomatic implant is 30 to 52.5 millimetres and passes alongside the sinus to anchor in the cheekbone, which does not shrink.Standard implantGrips the upper jawbonecheekbone — not usedsinusthin jawboneyour remaining upper teeth8–15 mmNothing solid left to hold itThis is when clinics say “you need a bone graft”Zygomatic implantReaches past it, into the cheekbonecheekbone — stays solidsinussame thin jawbonea full fixed bridge on top30–52.5 mmpasses beside the sinusAnchored above the missing boneOften no graft, and fixed teeth much sooner
Simplified side view for explanation only — not to anatomical scale. Implant lengths and placement are decided from your own CT scan.

How the implant relates to your sinus

The maxillary sinus is an air space sitting directly above the upper back teeth, and it is the reason standard implants often fail in this area — as the jaw shrinks, the sinus floor is all that remains. Zygomatic techniques deal with the sinus rather than avoiding it. Depending on anatomy and the surgeon's preferred technique, the implant may run along the outer wall of the sinus (an extra-sinus or extra-maxillary approach) or pass through it (an intra-sinus approach). Both are established; the choice is anatomical, not a matter of quality.

Because the sinus lining is involved either way, sinus-related problems are the complication surgeons watch most closely afterwards, and why nose-blowing restrictions are taken seriously in the first weeks. The honest detail on that sits in the risks and complications guide.

Where the very back of the arch also needs support and the sinus makes standard implants impossible, some surgeons add a pterygoid implant behind the sinus instead of grafting.

General anaesthesia or deep sedation?

Both are used. Which one you are offered depends on the length of the case, your medical history and the anaesthetist's assessment — not on cost. Ask which is planned for you, and why.

Focus of this site

General anaesthesia

Best for: Longer cases, quad zygoma, or anyone who wants no awareness at all

What you experience
You are fully unconscious from before the first incision until the surgery is finished. No memory of the operation.
Airway and monitoring
A protected airway managed by an anaesthetist, with continuous monitoring throughout.
Waking up
Recovery room, then the ward. Grogginess, a dry throat and nausea are common for the rest of the day.
Requirements
Fasting, blood tests and a fitness assessment; an overnight stay is usual.

Deep sedation with local anaesthetic

Best for: Shorter or less complex cases where full anaesthesia is not required

What you experience
Deeply relaxed and drowsy rather than unconscious. Most patients recall little or nothing, but you are not fully anaesthetised.
Airway and monitoring
Breathing on your own, with sedation and observation managed by an anaesthetist.
Waking up
Usually a quicker return to alertness, though the rest of the day should still be written off.
Requirements
Fasting and monitoring still apply; suitability depends on your medical assessment.

How many implants does a case need?

The count depends on how much usable bone remains at the front of the upper jaw. It is decided from the CBCT, not from a price list.

Last updated: July 2026
ConfigurationZygomatic implantsOther implantsTypically used when
Hybrid (single zygoma per side)2 (one per side)2 to 4 standard implants at the frontSome usable bone remains in the front of the upper jaw
Quad zygoma4 (two per side)None requiredAlmost no usable upper jawbone anywhere in the arch
Zygoma plus pterygoid2 (one per side)Pterygoid implants behind the sinus, sometimes with front implantsThe back of the arch needs support and grafting is being avoided

Configurations reflect indicative clinic practice; your own plan comes from your CBCT. Cost differences between configurations are set out in the cost guide.

The questions people actually ask before the day

Practical detail that tends to get skipped in consultations because it feels too small to ask about.

Will I ever be without teeth?
In a two-visit protocol, the intention is that you never leave the clinic without fixed teeth. Extractions, implant placement and the provisional bridge are staged inside the same visit, with the bridge fitted within roughly 24 to 72 hours of surgery. There is a short window between surgery and bridge fitting when your existing denture may be adjusted and worn, or left out, depending on the surgical site. Confirm the exact plan for your case in writing.
What happens if the surgeon changes the plan mid-operation?
It happens. Bone quality is only fully known once the site is exposed, and a surgeon may decide to add an implant, change an angle, or in rare cases delay loading the bridge. Consent forms are normally written to cover reasonable intra-operative changes. What matters is that you have discussed the likely variations, and their cost implications, beforehand.
How long does zygomatic implant surgery take?
Most cases are quoted at around two to four hours of operating time, with quad zygoma cases at the longer end. Add pre-operative preparation and recovery-room time and the day is longer than the surgery itself.
Is the surgery done in one session or split across days?
Implant placement is normally a single session. The prosthetic side is what spreads across days: impressions or scans after surgery, then fitting and adjusting the provisional bridge. That is why first visits are planned as five to seven days rather than a single appointment.
Should someone come with me?
Anyone having general anaesthesia should not travel or make decisions alone on the day. Most clinics treating international patients expect a companion, and packages are often quoted to include one.

Before your surgery date

Sorting these out in advance removes most of the avoidable stress, particularly if you are travelling for treatment.

  • 1Get the written treatment plan, implant configuration and total price before you book flights.
  • 2Give a complete medication list, including blood thinners, bisphosphonates, inhalers and supplements, to the anaesthetist and surgeon.
  • 3Declare every relevant condition — diabetes, heart disease, previous radiotherapy, sinus problems, autoimmune disease. Concealing them changes your risk, not your eligibility.
  • 4Ask which implant system will be used, and keep the batch details for your records.
  • 5Ask, in writing, who reviews you after you fly home and what happens if something goes wrong.
  • 6Check your travel insurance: many policies exclude complications of elective surgery abroad.
  • 7Arrange time off realistically rather than optimistically — see the recovery guide for a week-by-week picture.

How the angle is decided before surgery

Nothing about the trajectory is improvised in theatre. It is simulated on your CT beforehand so the path clears the eye socket, stays outside the sinus wall and lands in the body of the cheekbone.

Planning illustration, not a patient scan. Implant angles are simulated on 3D data before surgery so that the drill path clears the orbit and stays outside the sinus wall. Illustrative only.

What good planning looks like from your side

You cannot evaluate the surgery itself, but you can evaluate the process around it. Surgeons who do this regularly tend to show you the CBCT and explain where each implant will go, give an implant count with a reason attached, name the anaesthetist and the theatre, and describe their complication pathway without being asked twice. Ask how many zygomatic cases they complete in a year and whether they handle their own revisions. If you are weighing a UK pathway against treatment abroad, the UK options guide and the treatment in Turkey guide compare aftercare and cost rather than surgical principle.

Zygomatic implant surgery: frequently asked questions

How long does zygomatic implant surgery take?
Most cases are planned for around two to four hours of operating time, depending on how many implants are placed and whether extractions are needed at the same time. Quad zygoma cases usually take longer than hybrid cases. Expect the whole day to be taken up once preparation and recovery are included.
Am I awake during zygomatic implant surgery?
No. Surgery is carried out under general anaesthesia or deep intravenous sedation with local anaesthetic. Under general anaesthesia you are unconscious throughout; under deep sedation you are profoundly relaxed and usually remember little or nothing. Which is used depends on your medical assessment and the complexity of the case.
How soon do I get teeth after zygomatic implant surgery?
In most two-visit protocols a fixed provisional bridge is screwed onto the implants within 24 to 72 hours of surgery — the approach usually described as teeth in a day. It is fixed rather than removable, but it is temporary and is replaced by the definitive bridge months later.
How many zygomatic implants will I need?
Hybrid cases use one zygomatic implant per side with two to four standard implants at the front. Quad zygoma cases use four zygomatic implants and no jaw implants at all, and are chosen when almost no usable upper jawbone remains. The decision comes from your CBCT scan.
Do zygomatic implants go through the sinus?
Sometimes. Depending on your anatomy and the technique used, the implant may pass through the maxillary sinus to reach the cheekbone, or travel along its outer wall. Both approaches are established. Because the sinus is involved either way, sinus symptoms are monitored closely afterwards.
Why do I need two trips if the teeth are fitted straight away?
The first visit covers surgery and the fixed provisional bridge. The implants then need roughly four to six months to integrate with the bone before the definitive zirconia bridge is made and fitted, which is what the second visit is for. Healing times vary between patients and cannot be promised.
