Prosthodontic rehabilitation of midfacial defects.

A definition and classification of midfacial defects has been presented with a systematic approach to the prosthetic restoration of these defects. Patient factors, prognostic and diagnostic considerations, clinical procedures, fabrication, materials, and retention have been discussed. Patients with complex orofacial defects can be provided with prosthodontic treatment that results in an acceptable appearance and function consistent with the deficits encountered (Figs. 14 and 15).
