Pterygoid Implants: A Graftless Option for Severe Upper Jaw Bone Loss

If bone loss at the back of the upper jaw has left you thinking implants aren’t an option, pterygoid implants are one of the ways dental surgeons address that specific problem without bone grafting. Rather than adding bone where it’s missing, the implant is angled to anchor into denser, more stable bone that’s already there — the pterygoid process, just behind the upper jaw near the cheekbone region.

How it Avoids Grafting

In the posterior upper jaw, bone often resorbs after tooth loss, and the maxillary sinus can sit close to the ridge — two of the main reasons patients get told they need a sinus lift or bone graft first. A pterygoid implant is placed on an angle so it engages the pterygoid plate instead, a region that typically holds its density even when the jaw ridge above it has thinned. That’s the graftless part: the surgeon works with existing anatomy rather than building new bone before placing the implant.

Who This Suits

Pterygoid implants are generally considered for patients with significant bone loss in the back of the upper jaw who want to avoid sinus augmentation or grafting, often as part of a full-arch, fixed-teeth plan. Suitability depends on the anatomy of the pterygomaxillary region, which varies person to person — this is assessed through clinical examination and 3D imaging, not assumed from symptoms alone. It isn’t the right approach for every patient, and that’s determined case by case.

What The Published Evidence Shows

Reviews pooling data across thousands of pterygoid and maxillary tuberosity implants over multi-year follow-up have reported high long-term survival, though somewhat lower for pterygoid placements than for implants placed in the maxillary tuberosity. Most of the individual studies behind these reviews are retrospective case series, which is a real limitation of the evidence base — worth knowing before treatment, not after. Outcomes in the literature don’t apply automatically to any one patient; your own result depends on your bone anatomy, oral health, and how the case is planned. ScienceDirect

The Strategic-Implant Approach at Simpladent

Used as part of a wider, strategically planned implant layout — sometimes alongside standard or angled implants elsewhere in the arch — Pterygoid Implants can support a full-arch fixed prosthesis without a separate grafting stage. The plan starts with a CBCT scan and clinical assessment to confirm candidacy before anything is finalised.

A CT-based assessment is the only way to know if this applies to your case — that’s a consultation question, not a website one.
