Dental Implants Can Facilitate Orthognathic Surgery in a Patient With Severe Maxillary Atrophy.

The surgical treatment of dentofacial deformities is performed routinely and predictably in dentate patients. However, when dealing with the edentulous maxilla, treatment becomes more challenging and less predictable. In these cases, the combination of orthognathic surgery and osseointegrated implants could be a viable alternative to enable fixed rehabilitation. A patient with an edentulous and atrophic maxilla with maxillomandibular discrepancy and high esthetic requirement was treated with a combination of osseointegrated implants and orthognathic surgery. The rehabilitative sequence was composed of maxillary grafting procedures, installation of dental implants, placement of a fixed implant-supported prosthesis, and bimaxillary orthognathic surgery. During provisional restoration before orthognathic surgery, smaller teeth were used, allowing achievement of appropriate tooth length for the final restoration, even after natural and expected postoperative relapse. This restorative approach provided an implant-supported fixed prosthesis without prosthetic compensation and with optimum esthetics and biomechanics.
