Overview
Zygomatic dental implants are long implants placed in the cheekbone to support upper teeth when the upper jaw lacks enough bone for traditional dental implants. This guide explains how zygomatic implants work, who they help, what zygomatic implant surgery involves, and what to expect for cost. It is written for adults who have lost upper teeth and have been told they have severe bone loss.
Most dental implants sit in the jawbone. Zygomatic implants are different. They pass through or beside the sinus and anchor in the zygomatic bone, the very dense bone of the cheek. Because the cheekbone rarely shrinks the way the jaw does after teeth are lost, zygomatic implants can hold teeth even when the upper jaw is thin. For some people with major bone loss, this approach can reduce or replace large bone grafting procedures used to rebuild bone and replace missing teeth.
How Zygomatic Implants Work
Zygomatic implants are a way to attach a full upper set of teeth without rebuilding lost jawbone, using the cheekbone as a stable anchor.
How They Differ From Traditional Implants
Traditional dental implants are small screws placed into the jawbone. Traditional implants need a certain amount of dense bone to stay stable. When the upper jaw has shrunk, there may not be enough bone to hold them. Zygomatic implants solve this by reaching past the thin jaw and into the zygomatic bone.
A zygomatic implant is much longer than a standard implant, often around 30 to 52 millimeters. This length lets it bypass the weak upper jaw and grip the dense bone of the cheek. The result can be fixed teeth that do not move like a denture and feel closer to natural teeth.
When Zygomatic Implants Are Used
Zygomatic implants are mainly used for the upper jaw when severe bone loss makes conventional dental implants unreliable [3]. According to a systematic review of indications, they are often chosen for the badly resorbed (shrunken) upper jaw and after bone loss from trauma, gum disease (periodontal disease), or surgery to remove tumors [3].
Sometimes one or two zygomatic implants are combined with regular implants at the front of the mouth. In more extreme cases, four zygomatic implants support the whole upper arch. They are usually considered when the alternative is extensive bone grafting or when a graft has already failed [5].
What the Research Shows
Research describes favorable survival for zygomatic implants placed to support full-arch upper teeth [1][5]. A retrospective study examined patients who received zygomatic dental implants to support full-arch upper prostheses and reported positive clinical and radiographic results [1]. An earlier study followed 25 zygomatic dental implants for 11 to 49 months after loading [6].
The zygomatic success code, a set of measures proposed by Aparicio and colleagues, was created to judge outcomes more consistently across cases [5]. Results vary by patient, bone quality, and the skill of the surgical team.
What to Know Before Treatment
Zygomatic implant surgery is for adults healthy enough for oral surgery; it is not used in growing children whose facial bones are still developing.
There is no fixed upper age limit for zygomatic implants, but you need to be healthy enough for surgery and anesthesia. Your surgeon will review your medical history, medications, and habits such as smoking, which can slow healing. Active gum disease and untreated infection are usually treated first. A cone beam CT scan, a 3D X-ray, maps your zygomatic bone and sinus so the team can plan implant placement.
Planning matters more here than with traditional implants. Because the implants pass close to the eye socket and sinus, the team studies your anatomy in detail before zygomatic implant surgery. You may need to pause certain medications and arrange a ride home. In many cases, temporary teeth can be attached soon after surgery, so ask whether immediate loading fits your case [4]. Good oral hygiene supports long-term implant health [8].
- You have severe bone loss in the upper jaw
- You want fixed teeth rather than a removable denture
- You want to avoid bone grafting, or a graft has already failed
- You are healthy enough for oral surgery and anesthesia
What to Expect During Treatment
Zygomatic implant surgery usually happens in one session under general anesthesia or deep sedation, often with temporary teeth placed soon after.
The treatment moves through a few clear stages, from planning to your final teeth.
- Planning: A cone beam CT scan maps your zygomatic bone, sinus, and upper jaw to guide implant placement.
- Surgery: Under sedation or general anesthesia, the surgeon places two zygomatic implants, or up to four zygomatic implants, into the cheekbone. Regular dental implants may be added at the front.
- Immediate teeth: A temporary fixed bridge is often attached on or near the same day, so many patients do not leave without teeth [4].
- Healing: The implants bond with the dense bone of the cheek over several months.
- Final teeth: Once healing is complete, your prosthodontist fits the permanent bridge.
Recovery and Follow-Up
Some swelling and soreness are normal for the first week or two and are usually managed with prescribed medicine. Your team will schedule checkups to confirm the implants stay stable.
Serious problems are uncommon but possible. A systematic review of ocular complications found that injuries near the eye socket can occur with zygomatic implants, which is one reason this implant surgery should be done by an experienced specialist [2].
Cost Factors
Zygomatic implants usually cost more than traditional dental implants because they need advanced imaging, specialist surgery, and a full-arch prosthesis.
Costs vary by location, provider, and case complexity. A full-arch result on zygomatic implants is a major procedure, so it tends to cost more than single traditional dental implants. Price depends on how many zygomatic implants you need, whether regular implants are added, the type of anesthesia, and the materials in your final teeth. Ask for a written treatment plan that lists each fee.
Dental insurance often covers little of implant treatment, though some medical plans may help when tooth loss follows trauma or cancer surgery. Because zygomatic implants can reduce or remove the need for bone grafting, a plan may involve fewer separate surgical stages than a heavily grafted case [3]. Confirm coverage with both your dental and medical insurers before you start.
When to See a Specialist
See a prosthodontist or oral surgeon if you have severe upper bone loss, failed implants, or have been told you need major bone grafting.
A general dentist can place many traditional dental implants. Zygomatic implants are different. They require advanced training because the implants pass near the sinus and eye socket. Prosthodontists are dentists with extra training in replacing teeth [7]. You should be evaluated by a specialist if you were told there is not enough bone for conventional dental implants, if a bone graft has failed, or if zygomatic implants may be your only option for fixed teeth. A specialist can confirm whether you are a candidate or whether a sinus lift or bone grafting could still work.
- You were told you lack enough bone for traditional implants
- A previous implant or bone graft has failed
- You have severe bone loss from gum disease, trauma, or tumor surgery
- You want fixed upper teeth and want to discuss whether zygomatic implants fit your case
