Dentoalveolar surgery includes osteotomies and corticotomies of individual teeth to accelerate orthodontic tooth movement. This presentation includes the history of this technique and the more current applications. It has long been known that bone manipulation that includes osteotomy increases the bone metabolism/turnover rate. During a 2–6-week time frame the rapid movement of teeth that are orthodontically activated occur in response to this increase in bone turnover and increased metabolism. The hard and soft tissue response at this time is increased enough to allow changes not seen without this approach. In adult orthodontics this can be extremely helpful in movements that would normally not occur without this assistance or would be extremely slow. Comparison of the technique of each procedure will be reported. The biologic concepts and flap design for each technique are essential to successful use of these procedures. Care must be exercised to preserve blood supply to both the hard and soft tissues to avoid loss of teeth and the surrounding soft tissue component. Applications in the maxilla and mandible can yield unusual tooth movements in adults or the adolescent patients that require individual changes to finalize occlusal position in case completion. Patient presentation and outcomes will be presented to complete the review of these procedures and their applications in contemporary dentoalveolar surgery.
