What are zygomatic implants?
Zygomatic (zygoma) implants are specialized implants 30–52 mm in length, anchored not in the maxilla but in the zygomatic bone — one of the densest and most stable bone structures of the facial skeleton. They are used in patients with extreme bone loss of the maxillary alveolar ridge, where standard implants do not have sufficient support.
By anchoring in the zygomatic bone, full-arch reconstruction is possible without the need for prior bone grafts, sinus lifts, or months of waiting for bone regeneration. The patient receives fixed teeth on the day of the procedure.
Why Dr Sawicki?
Dr Paweł Sawicki is one of the few maxillofacial surgeons in Poland performing zygomatic and pterygoid implant procedures. The combination of maxillofacial surgery specialization with over 12 years of implantology experience and over 2000 completed procedures allows for safe execution of even the most challenging reconstructions.
Zygomatic vs pterygoid implants
Zygomatic Implants
Anchored in the zygomatic bone (os zygomaticum). Length 30–52 mm. Used for bone loss in the lateral and posterior maxilla. Bypass the maxillary sinus, eliminating the need for sinus lift.
Pterygoid Implants
Anchored in the pterygoid process of the sphenoid bone. Length 15–20 mm. Utilize one of the densest bone structures at the skull base. Supplement support in the posterior maxilla.
When are both types used simultaneously?
In cases of extreme, widespread maxillary bone loss, Dr Sawicki often combines zygomatic implants with pterygoid implants and standard implants in the anterior region. This approach provides multi-point support along the entire dental arch, allowing a stable full-arch bridge to be secured on the day of the procedure.
How is the procedure performed?
Zygomatic implant placement requires precise planning based on CBCT imaging and digital simulation. The maxillofacial surgeon inserts the implants through the maxillary alveolar ridge into the zygomatic bone, bypassing the maxillary sinus. The procedure is performed under local anesthesia and takes 2 to 3.5 hours, depending on the number of implants and case complexity.
On the same day, the prosthodontist working with the laboratory prepares a temporary bridge, which is then screwed onto the implants. The patient leaves the office with a complete dentition.
Who is suitable for zygomatic implants?
Zygomatic implants are indicated primarily for patients who have been refused implant treatment due to insufficient bone. This applies especially to:
- patients with long-term edentulism and advanced maxillary bone loss
- individuals for whom previous bone grafts have failed
- patients with extensive maxillary sinus pneumatization
- people wishing to avoid multi-stage treatment with bone augmentation (6–12 months of waiting)
- patients after maxillary resection due to tumors or trauma
Frequently asked questions
How do zygomatic implants differ from standard implants?
Standard implants are 8–16 mm in length and are anchored in the alveolar bone. Zygomatic implants are 30–52 mm in length and are anchored in the zygomatic bone, allowing their use even with minimal maxillary bone.
Is the procedure painful?
The procedure is performed under effective local anesthesia and is painless. After the procedure, swelling and discomfort may occur, which we manage with pain medications. Most patients return to normal activities within a few days.
Will I get teeth immediately?
Yes — zygomatic implants can be loaded immediately. The patient receives a temporary bridge on the day of the procedure. The final restoration is delivered after osseointegration, typically 3–6 months.
Are there alternatives to zygomatic implants?
The alternative is multi-stage treatment including bone augmentation (bone grafts, sinus lift), followed by standard implant placement. This process takes 6–12 months and requires several surgical procedures. Zygomatic implants allow this to be completed in a single day.
How durable are zygomatic implants?
Zygomatic implants have high durability comparable to standard implants. The zygomatic bone does not undergo resorption to the extent that the alveolar bone does, providing stable support for years. The key is regular hygiene and follow-up visits.
