Distraction osteogenesis for dental implants

Abstract

Distraction osteogenesis (DO) is a useful technique for the reconstruction of deficient alveolar ridges. In addition to recreating bone, soft tissues including keratinized gingiva are created. DO affords the clinician the opportunity to “overgrow” the bone, thus allowing osseous recontouring at the time of device removal and implant placement. The technique of DO can easily be mastered, yet the technique does require attention to detail, especially in device trajectory. Yet pitfalls and complications can be encountered. Mastery of these complications as well as the basic DO technique will be discussed in this course. Additionally, special case presentations such as anterior maxillary DO for esthetic implant reconstruction for patients status post avulsion of anterior teeth and bone, treatment of distal saddle deformities using DO and a posterior hinge, monocortical DO for knife edge ridges, evolving technology including the use of smaller, multi-vector distraction devices, DO for treatment of alveolar clefts as well as the use of DO-PRP sandwich technique and “immediate” DO for special cases will be offered.
