Diagnosis and Treatment of Dentoalveolar Discrepancies with Maxillary Zygomatic Anchorage and Dentoalveolar Distraction Osteogenesis

Date
January 26, 2024

Many orthodontic patients have discrepancies that cannot be corrected with conventional orthodontics, but yet, are not severe enough for orthognathic surgery. Accelerated orthodontics and skeletal anchorage have been used for a number of different dentoalveolar problems. Examples of these would include anterior open bites, anterior crossbites, excess overjet and constricted arches. This presentation will highlight goal directed treatment planning, based on the position of the upper and lower incisors, facial esthetics, smile esthetics and joint position. Dentoalveolar distraction osteogenesis (DDO) can be utilized to correct an unfavorable anteroposterior relationship between the maxillary teeth and the skeletal base. Skeletal anchor plates, which are implanted in the zygomatic buttress area, serve as absolute anchorage for maxillary molar intrusion. In addition, they can also be used for Class II correction. A wide variety of clinical cases at different stages of treatment will be presented. Also, the surgical procedure will be described and the orthodontic treatment sequence outlined.

Learning Objectives
