The Palatal Approach to Distraction Osteogenesis of the Anterior Maxillary Alveolus
1Private Practice, Tulare, CA.
Purpose:
This report describes the palatal approach to gain access for osteodistraction of the anterior maxilla to improve the vector of force during distraction.
Patient And Methods:
This case report illustrates a novel approach to anterior maxillary osteodistraction. The palatal approach allows the maxillary segment to be moved anteriorly and inferiorly. This is in contrast to the buccal approach, in which the palatal tissue creates a vector of force toward the palate. The vascular pedicle for the transport segment is the labial mucosa and musculature.
Results:
In the present case, the alveolar segment was advanced 3.6 mm anteriorly and 12.2 mm inferiorly as measured by pre- and postoperative computed tomograms. This patient with a large vertical alveolar defect and high smile line had successful restoration with dental implants. The result has been stable for 14 months.
Conclusion:
In this case, the palatal approach to the anterior maxillary osteotomy was shown to be an effective method of reconstructing a large vertical anterior defect.
