Bone reconstruction before an implant
When available bone cannot support an implant in an appropriate position, reconstruction may be considered after the prosthetic goal has been analysed.
Why bone may be insufficient
After extraction, infection, trauma or over time, a ridge may lose width or height. In the upper jaw, the maxillary sinus can also limit the available volume.
Main approaches
- Socket preservation at extraction.
- Onlay grafting to increase width or height.
- Sinus floor elevation.
- Guided bone regeneration with a membrane and graft material.
Choosing proportionate treatment
The approach depends on the defect, possible donor site, soft tissues, smoking, prosthetic plan and patient preference. A different implant, another prosthesis or avoiding grafting may sometimes be alternatives.
Recovery and risks
Swelling, bruising and discomfort are common. Infection, graft or membrane exposure, resorption, sinus complications, altered sensation or insufficient gain may occur. Smoking raises complication and failure risk.
After grafting
Contact the team for fever, discharge, worsening pain or swelling, exposed material, persistent bleeding or breathing problems.
