The Prima PlusTM Conical Implant System is intended for use in single-stage or two-stage surgical procedures for replacing single or multiple missing teeth in partially or fully edentulous mandibles and/or maxillae. The Prima Plus TM Conical Implant System supports single or multiple-unit restorations to re-establish patient chewing function and aesthetics. Prima PlusTM Conical implants are intended for placement following natural tooth loss or for immediate placement into an extraction socket. Immediate function may be achieved when good primary stability is established, and appropriate occlusal loading is applied.

All digitally designed custom abutments for use with Prima Plus TM Conical Implant System implants are to be sent to a Keystone Dental validated milling center for manufacture.

Indications for use as stated in the FDA summary.
