Bone Graft

01

Overview

A bone graft rebuilds lost bone volume to make an implant viable. The prolonged absence of a tooth, infections, periodontal disease and the use of a removable denture reduce the height and thickness of the ridge, and there is not always enough bone left to anchor an implant safely.
In the back of the upper jaw, the maxillary sinus tends to occupy the space left by the tooth; in these cases, a sinus lift raises the sinus membrane and creates height for the implant. The material may be the patient's own bone, a bone substitute (biomaterial) or a combination of the two, decided on the basis of the CBCT scan.

When to seek care

When bone is lacking, the implant gains a preliminary stage.

Seek an evaluation if you have been told you do not have enough bone for an implant, if you have worn a removable denture for many years or if you lost teeth to periodontal disease. These situations usually come with resorption of the ridge, which only a CBCT scan measures precisely.

A graft is also indicated before or together with implant placement in areas with thin bony walls. The need, the technique and the timing of the surgery are decided case by case, after the clinical and imaging evaluation.

  • Not enough bone for an implant
  • Teeth lost many years ago
  • Long-term denture wear
  • History of periodontal disease
  • Very large maxillary sinus
  • Thin or narrow ridge
  • Implant previously ruled out

Clinical note

Grafting bone is buying time to gain predictability: an implant placed in insufficient bone may even integrate, but it is unlikely to support the prosthesis for many years. I would rather postpone the surgery by a few months than leave the implant in a position the prosthesis cannot accommodate.
