这项前瞻性临床研究的目的是调查Procera AllCeram全瓷冠在前后部的长期存活率。1997-2005年间，共对50名患者进行了155颗氧化铝核Procera冠的植入治疗。2005年，患者被召回进行临床评估。39名患者135个牙冠参加了召回检查。在135个全冠中，103个位于后部，32个位于前部。术后5年和7年，前部累计存活率为100%，后部累计存活率为98.8%(1例冠折)。无论牙位、所使用的粘固剂(树脂复合体或玻璃离子粘固剂)，还是边缘减少或常规的核设计，临床上都取得了成功。Procera AllCeram似乎是一种可预测的技术，可用于前后部美观的全瓷单冠修复。
The aim of this prospective clinical study was to investigate the long-term survival of Procera AllCeram all-ceramic crowns in the anterior and posterior regions. Between 1997 and 2005, 155 Procera crowns with aluminum oxide cores were placed in 50 patients. Patients were recalled in 2005 for a clinical assessment. Thirty-nine patients with 135 crowns attended the recall examination. Of the 135 total crowns, 103 were located in the posterior region and 32 were located in the anterior region. The cumulative survival rate was 100% in the anterior region and 98.8% in the posterior region (1 crown fracture) after 5 and 7 years. Clinical success was achieved irrespective of the tooth position, cement used (resin composite or glass-ionomer cement), or the core design with reduced or conventional margins. Procera AllCeram seems to be a predictable technique for esthetic all-ceramic single crown restorations in the anterior and posterior regions.
