Evaluation of custom-made procera ceramic abutments for single-implant tooth replacement: a prospective 1-year follow-up study.
OBJECTIVE
The aim of this study was to evaluate the clinical performance of customized ceramic single-implant abutments in combination with two different techniques for fabricating crowns.


METHODS
Twenty consecutive patients were provided with 24 single-implant restorations with customized ceramic abutments. The restorations were either cemented to the abutment (n = 13) or fabricated with the veneering material fused directly onto the ceramic abutment (n = 11). The patients were evaluated at 6 and 12 months with radiographs and clinical parameters for complications and soft tissue response.


RESULTS
All implants and restorations were still in function after 1 year. Few clinical problems were reported during the follow-up period. The interproximal soft tissue recovered to near normal size. The mean marginal bone loss was similar for both groups, reaching an average of 0.3 mm (SD 0.71) after 1 year in function.


CONCLUSIONS
The short-term results indicate that customized ceramic abutments are successful and have comparable function, regardless of fabrication method.
