Subperiosteal Implants London
A precision-engineered implant solution for patients with severe bone loss, designed to rest directly on the jawbone surface and custom-fabricated using advanced 3D imaging and digital manufacturing.
A Custom-Engineered Alternative to Bone Grafting
Subperiosteal implants represent a significant evolution in implant dentistry for patients with severely atrophic jaws. Rather than being inserted into the bone — as conventional implants are — a subperiosteal implant is a custom-designed metal framework that sits on top of the jawbone, just beneath the gum tissue (the periosteum).
Each implant is fabricated using CBCT (cone beam CT) scans of the patient’s jaw, with the framework produced through laser sintering technology to ensure a precise, anatomically accurate fit. This level of customisation means the implant sits seamlessly against the bone surface, providing exceptional stability without the need for extensive bone grafting.
Pioneered in the mid-20th century and dramatically refined by modern digital manufacturing, subperiosteal implants are experiencing a significant clinical renaissance — and represent one of the most exciting developments in restorative dentistry for complex cases.
Key Advantage
Unlike zygomatic implants, subperiosteal implants carry no risk of sinus penetration or orbital involvement, making them particularly suitable for patients with complex upper jaw anatomy.
Which Solution Is Right for You?
Conventional Implants
Ideal where adequate bone volume exists. The gold standard for single tooth or multiple tooth replacement.
Subperiosteal Implants
For severe bone loss where endosseous implants are not feasible. Custom-fabricated, no bone graft required, no sinus risk.
Zygomatic Implants
For extreme upper jaw bone loss. Anchored in the cheekbone. Immediate loading in most cases.
Performed in London
Specialist Expertise, Start to Finish
Subperiosteal implant surgery is performed at our Queen Anne Street clinic by Mr Baha Bagdadi, our specialist oral surgeon (GDC 227851), who has extensive experience in advanced implantology for complex cases. Your custom framework is fabricated from your CBCT scan ahead of surgery, and every stage — from initial assessment to final restoration and follow-up — is carried out in one clinic, with a full written treatment plan agreed before surgery begins.
FAQ
Common Questions
What are subperiosteal implants?
Subperiosteal implants are a custom-designed metal framework that sits on top of the jawbone, just beneath the gum tissue, rather than being inserted into the bone like conventional implants. Each framework is fabricated using CBCT scans and laser sintering technology for a precise anatomical fit, providing stability without bone grafting.Who is suitable for subperiosteal implants?
Subperiosteal implants are suitable for patients with severely atrophic jaws where conventional implants are not feasible, even with bone grafting. They are particularly suitable for patients with complex upper jaw anatomy where zygomatic implants carry a sinus risk.What is the difference between subperiosteal and zygomatic implants?
Both are solutions for severe bone loss. Zygomatic implants anchor into the cheekbone and are suitable for extreme upper jaw bone loss with immediate loading in most cases. Subperiosteal implants sit on the jawbone surface and carry no risk of sinus penetration or orbital involvement, making them particularly suitable for patients with complex upper jaw anatomy.Do subperiosteal implants require bone grafting?
No. Subperiosteal implants are specifically designed for patients who cannot undergo bone grafting or for whom grafting would not provide sufficient bone volume. The custom framework rests on the existing bone surface, bypassing the need for grafting entirely.Where are subperiosteal implants performed?
Subperiosteal implant surgery is performed at our Queen Anne Street clinic in London by Mr Baha Bagdadi, our specialist oral surgeon (GDC 227851). The custom framework is fabricated from your CBCT scan ahead of surgery, with all planning, placement and follow-up care managed in one location.
