Digital design of a surgical guide for placement of definitive implants before orthodontic treatment.

Interdisciplinary treatment planning is an essential part of orthodontic therapy for patients with partial edentulism, especially when dental implants are to serve initially as anchorage and ultimately as prosthetic abutments for the definitive fixed restoration. A technique is presented for designing and fabricating a computed tomography-based surgical guide to place definitive implants before orthodontic therapy. First, the diagnostic cast and the orthodontic tooth arrangement and diagnostic waxing cast are scanned with a 3-dimensional optical scanner.
