[Clinical study on base bonding CAD/CAM customized zirconium abutment].
OBJECTIVE
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. Supported by Science and Technology Development Project of Hangzhou City(20120633B20) and Science Research Fund Key Specialist of Health and Disease of Hangzhou City(20130633B35).
