Severe Bone Loss, No More Grafting.

Conventional treatment for severe maxillary atrophy requires sinus lifts, block grafts and 18 months of staged surgery before implants can be placed. Zygomatic implants skip this entirely, fixed teeth in days, not years.

Even when the upper jaw has resorbed away, the cheekbone (zygoma) remains dense and reliable. Long zygomatic fixtures pass through the soft maxilla and lock into the dense zygoma above.

Zygomatic implants typically achieve high primary stability at placement. A fixed provisional bridge of 14 teeth is screwed onto them on the same day or the following day, no removable denture period.

When: The front of the upper jaw still has adequate bone, but the back does not.

What's involved: 2 conventional implants in the front, 2 zygomatic implants reaching back into the cheekbones. Together they support a full-arch fixed bridge.

Best for: Most zygomatic cases · Standard configuration.

When: Front of upper jaw has good bone, back has none. Maximum stability desired.

What's involved: 4 conventional implants in the front, 2 zygomatic implants in the back. 6 implants total per arch.

Best for: Heavy chewers · Long-term durability · When budget allows.

When: Severe maxillary atrophy where even the front of the upper jaw cannot reliably hold a conventional implant.

What's involved: 2 zygomatic implants per side (4 total per arch). The bridge is fully supported by the cheekbones.

Best for: The most severe atrophic cases · Patients who have failed other approaches.

When: Selected complex cases where additional posterior anchorage is needed.

What's involved: Combines zygomatic implants with pterygoid implants (anchored in the pterygoid plates at the very back of the upper jaw).

Best for: Specialty cases requiring additional posterior support.

Vinmec Da Nang and Link General Da Lat operate to international hospital theatre standards (positive pressure ventilation, full sterilisation, scrub teams). Zygomatic surgery requires this level of facility.

Surgery typically takes 5 hours under general anaesthesia. A qualified anaesthesiologist is present from induction to recovery. This is not a chair-side dental anaesthetic.

Cardiology, internal medicine, ENT and emergency teams are all on-site at our hospital-based branches. The risk profile of zygomatic surgery, while low in trained hands, justifies this level of backup.

Patients recover in a hospital recovery unit, not a dental office. Overnight observation is offered for older or medically complex patients.

Our four standard clinic branches (Hanoi Old Quarter, Hanoi Westlake, HCMC Thao Dien, Da Nang Hoàng Diệu) do not perform zygomatic implants. Consultations and follow-up can occur there; the surgery itself is referred to Vinmec Da Nang or Link General Da Lat.

For medically complex patients, we coordinate clearance with treating physicians abroad before scheduling surgery. Cardiology clearance is standard for patients over 65 or with cardiac history.

Soft food, no smoking, no straws, no vigorous nose blowing for 4 weeks. Antibiotics, pain relief and a saline nasal spray as prescribed. Provisional bridge in place throughout.

Provisional worn while implants integrate. Soft-to-normal diet progression. WhatsApp check-ins with our team if you have travelled home.

Brush twice daily with a soft toothbrush. A water flosser is essential, full-arch bridges have hard-to-reach undersides. Interdental brushes around each implant head.

Zygomatic implants pass through or near the maxillary sinus. Be alert to persistent sinus symptoms (chronic nasal congestion, recurrent sinus infections) and report them, this is uncommon but important to address early if it occurs.

Professional cleaning, soft-tissue check around each implant, visual inspection. Annual CBCT review at year 1 and every 5 years thereafter for monitoring.

Smoking is the single biggest threat to implant longevity. Untreated peri-implantitis is the second. Hard objects, extreme bite forces and sleep bruxism without a night guard are all unkind to the bridge.

Long-term clinical literature reports zygomatic implant survival above 95 percent at 10 years in trained hands, comparable to conventional implant survival. The technique has been documented since 1998 with extensive published outcomes data.

Sinusitis (the most common, typically managed with antibiotics or rare surgical revision). Nerve injury (rare with CBCT planning). Orbit involvement (extremely rare with experienced surgeons). Implant failure (rare, comparable to conventional).

CBCT 3D planning of every zygomatic trajectory before surgery. Hospital-based theatre. Qualified anaesthesiologist on-site. Surgery performed only by Dr. Evans, our trained zygomatic specialist. Genuine Nobel Biocare or Straumann fixtures only.

If a zygomatic implant fails to integrate within 6 months, we re-place it at no additional cost. Sinus complications are addressed with appropriate medical and ENT support, including referral to ENT specialists at our hospital-partner branches.

Smoking significantly increases sinusitis risk and implant failure risk. We require honest disclosure during consultation, and strongly recommend stopping at least 2 weeks before surgery and 8 weeks after.

Active sinus disease, untreated periodontal disease, IV bisphosphonate therapy, recent radiation to the maxilla, severely uncontrolled diabetes. We tell you honestly when zygomatic surgery is not the right choice.

For patients with adequate maxillary bone or mild atrophy, conventional All-on-4 may be the right answer. We tell you honestly which protocol fits.
