Bone-substitution and remodelling of the jawbones A review

Replacement of defects of the jawbones is one of the rapidly developing fields of maxillofacial surgery. The main criterion for the success of bone replacement is effective remodelling, i.e. the quantitative transformation of the inserted bonesubstitute material into bone of the same quality and the same structure as the original.

The aim of this report is to survey the literature background of our knowledge relating to remodelling.

An account is given of the mechanism of transformation of the bone-substitute material into bone, and of clinical, radiological and histologic methods with which the transformation can be appropriately followed.

Remodelling is a protracted process, and conclusions relating to it can be drawn only from examinations performed at isolated points of time, which are often difficult to objectify. We may speak of complete remodelling if the inserted material can no longer be recognized, and only bone with a structure agreeing with that of its environment is to be seen in the augmented area.
