Abstract

The surgical treatment of dentofacial deformities is performed routinely and predictably on dentate patients. However, when dealing with the edentulous maxilla, treatment becomes more challenging and less predictable. In these cases, the combination of orthognathic surgery (OS) and osseointegrated implants (OI) may be a viable alternative to enable fixed rehabilitation. A patient with an edentulous and atrophic maxilla with maxillo-mandibular discrepancy and high aesthetic requirement, was treated with a combination of osseointergrated 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 prior to OS, smaller teeth were used, allowing achievement of appropriate tooth length for the final restoration, even after natural and expected post-operative relapse. This restorative approach provided an implant-supported fixed prosthesis without prosthetic compensation with optimum aesthetics and biomechanics.
