Pterygoid and Zygoma implants are indicated in the cases which have insufficient bone but want an implant supported prosthesis. These implants can be placed in severely resorbed jaw bone with minimal surgical trauma and maximum oral function. These implants can be an alternative to sinus lift procedure for indicated cases. The implants can be placed in better quality bone, which establishes stable anchorage for non-removable teeth.
Such implants have provided successful support for a variety of prosthesis forms, including multi-implant complete arch fixed prostheses ,complete removable over dentures with fixed retention bars, multiple implant supported restorations.
