ABSTRACT
PURPOSE: To evaluate the clinical application of base bonding customized zirconium abutment. METHODS: A total of 141 base bonding customized zirconium abutments used in 114 implant-supported cases during 2010.6-2012.11 in Hangzhou Stomatology Hospital were involved in the study. To evaluate the efficacy, they were followed up for 3 months to 2 years. RESULTS: Among 141 abutments, 140 were successfully applied to implant prosthesis at first time. During the observation period, partial zirconia exfoliation from bases occurred in 1 abutment. All the patients and dentists were satisfied with the final esthetic outcomes. CONCLUSIONS: The clinical effect of base bonding customized zirconium abutment is acceptable.
