The moment a patient is told they aren’t a candidate for dental implants is often a defining one. It frequently happens at a general dental clinic, based on a panoramic X-ray review, without specialist input. Sometimes that assessment is accurate. Often it isn’t. Zygomatic and pterygoid implants exist precisely for patients who fall outside the parameters of conventional implantology. This guide is written for patients who have received that “not a candidate” verdict and want to understand what options actually remain.
The Specific Problem These Implants Solve
Conventional dental implants require the alveolar bone to anchor in. When this bone has resorbed significantly, conventional implants either cannot achieve adequate primary stability, or their placement would require bone grafting procedures first. In the upper jaw specifically, bone loss is compounded by maxillary sinus expansion. Zygomatic implants solve this by anchoring in the zygomatic bone (cheekbone) — dense cortical bone that does not resorb regardless of tooth or ridge bone loss. Pterygoid implants solve the same problem in the posterior upper jaw by anchoring in the pterygoid plates.
Questions Every Patient Should Ask
Was a CBCT scan done? A 2D panoramic X-ray cannot accurately assess bone width or the three-dimensional relationship between proposed implant sites and anatomical structures.
Has All-on-4 with angled implants been considered? Many patients told they don’t have enough bone for conventional implants are actually candidates for All-on-4, which uses angled posterior implants specifically to work in areas of moderate resorption.
What is the surgeon’s specific training in zygomatic implants? This is not a procedure that generalises from conventional implant experience. Ask directly how many zygomatic implant cases the surgeon has performed.
How Zygomatic and Pterygoid Implants Work Together
Common configurations: two zygomatic implants (one per side) + two conventional anterior implants; four zygomatic implants (quad-zygoma) for cases of severe maxillary atrophy; two zygomatic + two pterygoid implants for specific anatomical configurations. The specific combination is determined by the patient’s anatomy and the CBCT findings.
What to Expect at Dazzle Dental Clinic
Every zygomatic and pterygoid implant case at Dazzle begins with a CBCT review — which can be done remotely. Surgery is performed under local anaesthesia and IV sedation. A provisional prosthesis is attached the same day. Initial recovery takes 5–7 days; the final prosthesis is fitted at 3–6 months post-surgery. For the treatment workflow and prosthetic delivery detail, see our zygomatic implant treatment workflow guide.
FAQs
Q1: How do I know if I need zygomatic implants or if regular All-on-4 would work?
A CBCT scan reviewed by a specialist who performs both procedures is the only reliable way to answer this.
Q2: Can pterygoid implants be used on the lower jaw?
No. Pterygoid implants are specific to the upper jaw (maxilla).
Q3: How long is the recovery after zygomatic implant surgery?
Most patients are comfortable for travel and normal activity within 7–10 days. Full tissue healing occurs over 3–6 months alongside osseointegration.
Q4: Is there an age limit for zygomatic implants?
No. Systemic health, medication profile, and bone anatomy are the relevant factors, not age.
