[Clinical application of implant-supported restoration with all-ceramic crown fused to small-size titanium abutment].

OBJECTIVE: To get aesthetic implant-supported restorations by means of the all-ceramic crown fused to small-size titanium abutment and evaluate the quality of the restorations. METHODS: A small-size titanium abutment that had extremely thin circumferential collar and axial wall was fabricated, while a Cercon all-ceramic crown made with computer aided manufacture (CAM). The crown was fused to the abutment by firing the opaque porcelain. A total of 6 restorations in 5 patients were installed and assessed according to the California Dental Association (CDA) quality evaluation system. RESULTS: All the restorations were fabricated well and ranked in clinic evaluation excellent for surface, anatomical form, marginal quality, and color at baseline and one year after insertion, respectively. CONCLUSIONS: The restoration of all-ceramic crown fused to titanium small-size abutment is a new aesthetic alternative for the implant-supported restoration.
