The porcelain laminate veneer is an elective restoration, often placed in the absence of disease for purely esthetic reasons. As such, it would appear desirable that the success rate of the technique was 100%. It is therefore the purpose of this paper to review the literature on porcelain laminate veneer survival by searching dental databases containing clinical trials of porcelain veneer restorations. References of selected trials were also screened to identify relevant studies. Each paper that was included was examined to ascertain if preparation into dentin affected survival. A total of 24 papers were included in the review. It was concluded that survival rates of porcelain laminate veneers are rarely 100%, and there is reasonable evidence indicating that a veneer preparation into dentin adversely affects survival.
A review of the literature has indicated that porcelain laminate veneer survival is rarely 100%. Accordingly, patients should be made aware of this before embarking on this elective restorative technique. Clinicians should also be aware that the ideal preparation for porcelain veneers remains within enamel.
瓷贴面是一种选择性修复体，通常因纯粹的美观原因而在无疾病的情况下放置。因此，似乎需要该技术的成功率达到 100%。因此，本文的目的是通过搜索包含瓷贴面修复临床试验的牙科数据库来回顾瓷贴面存活率的文献。还筛选了选定试验的参考文献，以确定相关研究。将纳入的每一篇论文都进行了检查，以确定是否对牙本质进行了准备会影响存活率。共有 24 篇论文纳入了综述。结论是，瓷贴面的存活率很少达到 100%，并且有合理的证据表明，贴面制备到牙本质会对存活率产生不利影响。
文献回顾表明，瓷贴面存活率很少达到 100%。因此，在开始这种选择性修复技术之前，应让患者了解这一点。临床医生还应注意，瓷贴面的理想制备仍然在牙釉质内。
