本研究评估了115个蚀刻瓷层压板贴面放置由一个单一的操作者在纽约大学牙科中心在1982年和1985年之间。修复体分为两组。第一组包括43个不使用任何牙齿准备的牙齿矫正;第二组包括72个使用倒角准备的牙齿矫正。美国公共卫生署标准用于记录腔面边缘变色、边缘完整性和龋齿的存在。临床检查还显示了脱粘和/或瓷断裂的数量。牙周评估包括使用基线和召回石头复制品的修复牙齿，以测量的高度，采取面中部的修复体的切缘的游离牙龈边缘。还记录牙龈轮廓的任何变化。同时记录菌斑和牙龈指数。研究中发现的低断裂率和脱粘率与无龋齿发生率相结合似乎表明这些牙列的功能令人满意，并且牙周不良反应最小。
This study evaluated 115 etched porcelain laminate veneers placed by a single operator at New York University Dental Center between 1982 and 1985. The restorations were divided into two groups. Group I consisted of 43 restorations placed without any tooth preparation; Group II consisted of 72 restorations placed using a chamfer preparation. The U.S.P.H.S. criteria was used to record cavosurface marginal discoloration, marginal integrity, and presence of caries. A clinical examination also revealed the number of debonds and/or the number of fractures of porcelain. A periodontal evaluation included the use of baseline and recall stone replicas of restored teeth to measure the height of the free gingival margin taken mid-facial to the incisal edge of the restoration. Any changes in gingival contour were also noted. Plaque and gingival indices were also recorded. The low fracture and debond rate found in the study combined with no incidence of caries seem to indicate that these restorations are functioning satisfactorily and with minimal negative periodontal response.
