Zygomatic Implants: A Solution for Severe Upper Jaw Bone Loss

How Zygomatic Implants Differ from Standard Implants

Standard dental implants rely on the alveolar bone, the part of the jaw that once held natural teeth. When teeth are missing for a long time, or when a patient has worn dentures for years, this bone resorbs and shrinks. In the upper jaw, the maxillary sinuses also expand downward, leaving even less bone to work with.

Zygomatic implants solve this problem by skipping the compromised jawbone entirely. They are angled through the back of the upper jaw and into the cheekbone, which remains dense and stable regardless of how much jawbone has been lost.

Good Candidates

• Patients with severe maxillary (upper jaw) bone atrophy who have been told they cannot receive standard implants
• Long-term denture wearers whose upper jawbone has resorbed significantly over the years
• Patients who have had failed bone grafts or do not want to undergo bone grafting procedures
• Patients who have lost upper jaw bone due to trauma, tumor removal, or congenital conditions
• Patients who want fixed (non-removable) upper teeth and cannot get them with conventional implants alone

Who May Not Be a Good Fit

Patients with enough upper jaw bone for standard implants typically do better with conventional placement, which is a simpler procedure. Zygomatic implants are also limited to the upper jaw. Patients with lower jaw bone loss need different solutions, such as short implants or bone grafting.

Uncontrolled diabetes, active sinus infections, heavy smoking, and certain medications that affect bone healing may affect candidacy. Your specialist will evaluate your overall health and imaging before recommending this procedure.

Planning and Imaging

Before surgery, your specialist takes a 3D scan of your skull to measure the cheekbone density, sinus position, and the angle needed for implant placement. Digital planning software allows the surgeon to virtually place the implants and design a surgical guide for precise positioning. Impressions or digital scans of your mouth are used to fabricate a temporary set of teeth in advance.

The Surgery

On the day of surgery, you will receive general anesthesia or IV sedation. The surgeon makes an incision in the gum tissue along the upper jaw, exposes the bone, and creates channels for the zygomatic implants to pass through the jawbone and into the cheekbone.

Most patients receive two zygomatic implants in the back of the upper jaw combined with two to four standard implants in the front (where bone is usually better preserved). In cases of extreme bone loss, four zygomatic implants may be used. The temporary fixed teeth are typically attached the same day.

Same-Day Teeth

One of the major advantages of zygomatic implants is that patients can often leave the office with a fixed set of temporary teeth on the same day as surgery. These temporary teeth are functional but are made from acrylic and are not the final restoration. They allow you to eat soft foods and speak normally while the implants integrate with the bone over the next several months.

The First Week

Swelling, bruising around the cheeks and under the eyes, and mild to moderate discomfort are normal during the first 5 to 7 days. Your specialist will prescribe pain medication, antibiotics, and an antiseptic mouth rinse. A soft food diet is required. Ice packs help manage swelling during the first 48 hours.

Weeks 2 Through 6

Swelling and bruising gradually resolve. Most patients feel significantly better by week 2 and can return to normal activities. You will continue eating soft foods for 4 to 6 weeks to protect the implants while they integrate. Follow-up visits monitor healing and check the temporary teeth.

Final Teeth (3 to 6 Months)

After the implants have fully integrated with the cheekbone (typically 3 to 6 months), your specialist replaces the temporary acrylic teeth with the permanent restoration. This is usually a zirconia or porcelain hybrid bridge that looks and functions like natural teeth.

Possible Complications

• Sinusitis: Because the implants pass near or through the maxillary sinus, sinus infection or inflammation can occur. This is the most commonly reported complication and is usually treatable with medication.
• Numbness or tingling: Temporary numbness in the cheek or upper lip area can occur if nearby nerves are affected during surgery. This typically resolves within weeks to months.
• Implant failure: While uncommon with experienced surgeons, an implant may fail to integrate with the bone. If this happens, the implant can often be replaced.
• Soft tissue complications: The gum tissue around the implant may become inflamed or recede, requiring additional treatment.
• Infection at the surgical site: Managed with antibiotics and proper wound care.
