【摘要】[Objectives] To explore the difference between the CAD/CAM customized zirconia abutment and the finished titanium abutment in the maxillary anterior region. [Methods] A total of 60 implants were selected from 60 patients who had undergone maxillary single anterior implant implantation in the Department of Oral and Maxillofacial Surgery, Affiliated Hospital of Qingdao University from July 2017 to July 2018. They were randomly divided into an observation group and a control group(30 patients/group). The observation group used CAD/CAM customized zirconia abutment and all-ceramic crown, while the control group used finished titanium abutment and all-ceramic crown. Twelve months after the crown restoration, mechanical complications, pink esthetic(another spelling of aesthetic) score(PES) and white esthetic score(WES), and patient satisfaction were used as clinical observation indicators to evaluate the restoration effect. [Results] For 12 months after crown restoration, the implant survival rate of the two groups of patients was 100%, and there was no abutment breakage, loosening, falling off, or screw loosening and breakage. The PES and WES of the observation group were significantly higher than those of the control group(P<0.05). The patient satisfaction of the observation group was significantly higher than those of the control group(P<0.05). [Conclusions] CAD/CAM customized zirconia abutment implant restoration in the maxillary anterior region can obtain good esthetic restoration effect in a short term, and has good clinical application effect.
