The digital workflow and the application of Computer-Aided Manufacturing (CAM) to prosthodontics present the clinician with the possibility of adopting new materials that confer several advantages. Especially in the case of zirconia, these innovations have profoundly changed daily practice. This paper compares the satisfaction and perception of patients who received implant-supported single crowns (SC) and fixed partial dentures (FPD) made from zirconia, either monolithic or partially veneered, after 3 years of follow-up; the success and survival rate of these restorations were also measured. Forty patients, who had been previously treated with implant-supported SC or FPD, either monolithic or partially veneered, and submitted to a yearly maintenance program, were recalled 3 years after their treatment and requested to complete an 8-question questionnaire regarding their perceptions of the treatment. Any mechanical or biological complication that had occurred from the time of delivery was also recorded. Patients that experienced ≥1 complication were less likely to be prone to repeat the treatment. The 3-year success rate was 92.6% for monolithic restoration and 92.3% for partially veneered restoration, while the survival rate was 100% for both restorations. The 3-year follow-up found that monolithic and partially veneered zirconia restorations are both well-accepted treatment options, and patients preferred the veneered restorations (0.76, < 0.05) from an aesthetic point of view. According to our results, monolithic and veneered zirconia restorations are both reliable treatment options and are both equally accepted by patients.
数字化工作流程和计算机辅助制造（CAM）在修复体中的应用为临床医生提供了采用新材料的可能性，这些新材料具有许多优势。尤其是在氧化锆的情况下，这些创新极大地改变了日常实践。本文比较了接受种植体支持的单冠（SC）和固定局部义齿（FPD）修复的患者在 3 年随访后的满意度和感知，这些修复体的成功率和存活率也进行了测量。40 名患者先前接受过种植体支持的 SC 或 FPD 修复，无论是整体还是部分贴面，都接受了每年的维护计划，并在治疗 3 年后召回并要求完成一份关于他们对治疗的看法的 8 个问题的问卷。还记录了从交付开始出现的任何机械或生物并发症。经历过≥1 次并发症的患者不太可能再次接受治疗。整体修复的 3 年成功率为 92.6%，部分贴面修复的 3 年成功率为 92.3%，而两种修复体的 3 年存活率均为 100%。3 年随访发现，整体和部分贴面氧化锆修复都是可接受的治疗选择，患者更喜欢贴面修复（0.76，<0.05）从美学角度来看。根据我们的结果，整体和贴面氧化锆修复都是可靠的治疗选择，患者对它们的接受程度是相同的。
