Monolithic zirconia prostheses on teeth or implants have been proposed in recent years as a potential treatment. To date, limited data regarding the outcomes of these prostheses have been presented and are mainly based on limited sample size and short-term follow-up. Data on complete-arch monolithic zirconia prostheses are relatively scarce.
The purpose of this retrospective study was to evaluate the clinical performances of 26 implant-supported, complete-arch, monolithic zirconia restorations with facial feldspathic porcelain veneers for the rehabilitation of completely edentulous patients.
All patients' charts from 2 private practices from 2010 to 2013 were reviewed. Patients rehabilitated with a complete-arch implant-supported monolithic zirconia prostheses were included in the study. Several parameters were recorded so as to evaluate the outcome of these rehabilitations: implant survival and success rates, prosthesis survival rate, interproximal bone loss, periimplant probing depth, and bleeding on probing. The number and type of prosthetic complications were also recorded. Data were analyzed with descriptive statistics.
Eighteen patients were treated with a total of 26 complete-arch fixed prostheses. The mean follow-up time was 20.9 months (SD 13.6; range, 10 to 36 months). In total, 154 implants were placed supporting 309 retainers and pontics. The implant survival rate was 100% and the success rate was 94.8%. Mean bone loss was 0.66 mm (SD 0.59 mm). Mean probing depth was 3.4 mm (SD 0.92 mm). Bleeding on probing was positive in 19% of probing sites. The prosthesis survival rate was 100%.
The results of this retrospective evaluation showed that monolithic zirconia restorations with facial porcelain veneer provided satisfactory clinical performance and suggest that these rehabilitations are a viable treatment option for completely edentulous patients.
近年来，牙齿或种植体上的整体式氧化锆修复体被提议作为一种潜在的治疗方法。迄今为止，关于这些修复体效果的数据有限，且主要基于样本量有限和短期随访。关于全牙弓整体式氧化锆修复体的数据相对较少。
本回顾性研究的目的是评估26例采用种植体支持、全牙弓、带有面部长石质烤瓷贴面的整体式氧化锆修复体修复全口无牙患者的临床性能。
回顾了2010年至2013年两家私人诊所所有患者的病历。纳入采用全牙弓种植体支持的整体式氧化锆修复体进行修复的患者。记录了几个参数以评估这些修复的结果：种植体存活率和成功率、修复体存活率、邻间骨丢失、种植体周围探诊深度和探诊出血情况。还记录了修复并发症的数量和类型。采用描述性统计方法分析数据。
18例患者共接受了26个全牙弓固定修复体治疗。平均随访时间为20.9个月（标准差13.6；范围10至36个月）。总共植入了154颗种植体，支持309个固位体和桥体。种植体存活率为100%，成功率为94.8%。平均骨丢失为0.66毫米（标准差为0.59毫米）。平均探诊深度为3.4毫米（标准差为0.92毫米）。19%的探诊部位探诊出血呈阳性。修复体存活率为100%。
这项回顾性评估的结果表明，带有面部烤瓷贴面的整体式氧化锆修复体具有令人满意的临床性能，并表明这些修复方法是全口无牙患者可行的治疗选择。
