Esthetic Rehabilitation of Anterior Implants Using Chairside Cad-Cam Custom Ceramic Abutments

Custom abutments may solve many esthetic problems in extremely challenging anterior implant prostheses. One of the technique to create custom abutments is using Computer-Aided Design and Computer-Aided Manufacturing (CAD-CAM) technology. CAD-CAM which enables to fabricate abutments from zirconia and lithium disilicates. This clinical report describes the use of custom ceramic abutments fabricated using CAD-CAM technology for limited mesiodistal space situations in maxillary anterior region of two cases. In both patients, implants were placed for replacement of left maxillary central incisor were restored with CAD-CAM fabricated ceramic custom abutments. The abutments were fabricated from zirconia and lithium disilicate in case 1 and case 2, respectively. Then, lithium disilicate crowns were fabricated on the abutments. After 12 months, both patients were satisfied with the restorations. In case 2, abutment screw loosening was observed after 5 months of function however no other complication was observed during 12 months.
