Titanium Implants in the Zygoma as Retaining Elements After Hemimaxillectomy

Obturator prostheses require anchoring elements in the partially resected maxilla to provide stability and oronasal separation. Anchoring elements are usually overstressed because of the lack of collateral support. Intraoral titanium implants can provide additional retention and avoid mechanical overstress of the anchoring elements in the residual maxilla. Treatment with intraoral implants into the zygoma for the support of an obturator prosthesis is reported.
