Alveolar distraction osteogenesis for implant site development.
Alveolar distraction osteogenesis can be a valuable tool for implant site development. Simultaneous regeneration of hard and soft tissue and an overall decrease in treatment time compared with other methods of site preparation can be an advantage. The authors advocate the concept of "prosthetically driven alveolar distraction." Surgical planning should begin with visualization of the final restoration to determine the volume and position of the soft and hard tissue deficiency. Surgical guides will help the surgeon determine the vector of distraction. Adherence to surgical principles to avoid damage to adjacent vital structures and maintain vascular supply to the transport segment is necessary for success. Bone grafting may be necessary before or after distraction to increase the surgical success of the procedure. Close follow-up is needed to verify the appropriate distraction vector and volume. Patient management and acceptance should be considered in distractor design and placement.
