The coating of zirconium ceramic on the transmucosal collar of the Compound Implant particularly indicated for a single-stage surgical implant technique. The isolating properties and the high wettability of this material favor gingival healing and reduce the accumulation of plaque: the esthetic collar permits a supragingival or juxtagingival cervical margin favoring plaque control and minimizing the consequences of tis sue remodeling. The hardness of the ceramic also allows it to undergo conventional prophylaxis with ultrasonic scalers without alteration of its surface quality. In addition to the above-mentioned advantages, the TFM coping/abutment, an implant-prostheis connector in alumina ceramic, for use in a two-stage technique, provides electrogalvanic isolation of the implant, and personalized abutment preparation allows for simplified fabric ation of an implant-supported prosthesis.
