Why bone may be missing
After tooth loss, the jawbone gradually resorbs. Periodontal disease, infection, trauma, long-standing extractions or previous implant failures can also reduce the available bone volume.
Techniques
- Autogenous bone grafts — bone harvested from the patient;
- Bone substitutes — biological or synthetic materials;
- Guided bone regeneration — membranes and filling materials;
- Sinus lift — to gain height in the posterior upper jaw;
- Extensive reconstructions — for severe atrophy.
Alternatives
Grafting is only proposed when the existing bone does not allow reliable implant treatment. Depending on the situation, alternatives may be discussed: shorter implants, angled implants or, in selected cases of severe atrophy, custom subperiosteal implants. The decision is always based on 3D imaging and the overall prosthetic plan.
Complex cases
Severe bone loss, previous failures and extensive reconstructions are one of the main focuses of Dr Chambas's practice. When indicated, these procedures can be performed under general anesthesia in the operating theatre of the Clinique du Parc in Lyon.
