ABSTRACT
The use of hydroxylapatite mixed with autogenous bone to augment the area posterior to the mental foramen is described. This method is combined with an interposed bone graft technique in the symphyseal area. The clinical implications are discussed in relation to potential nerve damage, height to be gained, and effects on lip-chin profile, and the results in 29 patients are reported.

A long-term follow-up (7-2 years) of 152 patients who underwent a vestibuloplasty is presented. Special emphasis has been put on the condition of the graft, nerve disturbances and chin contour changes. As a result of this study, a mandibular vestibuloplasty procedure is recommended that has minimal side effects, and yet provides an adequate base on which to build a denture on.

A follow-up study on 41 patients who had augmentation of the atrophic mandible by interposed bone graft is presented. Special emphasis has been put on the prosthetic implications. The rapid reduction in height measured postoperatively appeared almost to cease after 6 months. Some of the possible causes of this phenomenon are discussed.
