这项研究获得了关于本科生使用固定义齿进行义齿修复的长期效率的信息。从1975年至1976年牙科学校本科生治疗的出院患者名单中，101人在6年、11年和18年后被召回进行免费临床检查。共植入固定局部义齿163颗。固定义齿以丙烯酸树脂贴面-金修复体为主，占85%；金属烤瓷修复体占15%。在这项研究期间，14名患者死亡，剩下138名固定部分义齿接受检查。其中，35例(25%)在平均功能11年后被移除，其中75%在18年后仍处于原位和功能状态。拔除的主要原因包括龋病、牙周炎、牙根折断和牙髓并发症。金属烤瓷修复体的拔除量少于丙烯酸树脂贴面-金质修复体。铸造桩核基牙的去除率高于全基牙的去除率。中等悬臂伸展的固定部分义齿与端支撑伸的固定局部义齿的拔除频率没有差异。
This study obtained information on the long-term efficiency of prosthetic rehabilitation with fixed partial dentures performed by undergraduate students. From a list of discharged patients treated from 1975 to 1976 by undergraduate students at a dental school, 101 were recalled for free clinical examinations after 6, 11, and 18 years. A total of 163 fixed partial dentures were inserted. The majority (85%) of the fixed partial dentures were acrylic resin veneer-gold restorations; 15% were metal ceramic restorations. During this study period, 14 individuals died, leaving 138 fixed partial dentures to be examined. Of these, 35 (25%) were removed after a mean of 11 years in function, which left 75% in place and functioning after 18 years. The main causes for removal included caries, periodontitis, root fracture, and endodontic complications. Fewer metal ceramic restorations than acrylic resin veneer-gold restorations were removed. The removal rate for abutments with cast posts and cores was higher than the removal rate of total abutments. There was no difference in removal frequency between fixed partial dentures with moderate cantilever extensions and those with end-supported extensions.
