The aim of the present study was to present the design and one-year results of a study of crowns and fixed partial dentures (FPDs) made with the Procera system. All patients at one clinic needing fixed prosthodontic restorations during a two-year period were invited. All 260 patients accepted to participate and they received 333 ceramic veneered Procera restorations-242 single crowns and 91 FPDs. The loss of patients during the one-year follow-up was only 5%. The restorations were evaluated according to a modified version of the California Dental Association rating system. Practically all Procera restorations were judged as satisfactory both at base line and at the one-year follow-up examination. Two crowns and one FPD showed fractures of the ceramic veneering. Another FPD had a fracture of a welded joint. Three single crowns came loose but could be recemented. In conclusion, the ceramic veneered Procera titanium restorations were well accepted by the patients and the success rate was high during the one-year follow-up period.
本研究的目的是介绍一项关于使用Procera系统制作的牙冠和固定局部义齿（FPD）的研究设计及一年的研究结果。邀请了一家诊所中在两年期间需要进行固定修复义齿治疗的所有患者。所有260名患者均接受参与研究，他们共接受了333颗Procera烤瓷修复体——242颗单冠和91颗FPD。在一年的随访期间患者流失率仅为5%。根据加利福尼亚牙科协会评级系统的修订版对修复体进行评估。实际上，所有Procera修复体在基线和一年随访检查时均被判定为满意。两颗牙冠和一颗FPD出现烤瓷贴面骨折。另一颗FPD出现焊接处骨折。三颗单冠松动，但可以重新粘结。总之，Procera钛烤瓷修复体受到患者的广泛接受，在一年的随访期内成功率很高。
