问题的陈述。由于缺乏临床研究，具有Dahl概念的树脂粘合固定部分牙科修复体（RBFPDPs）的金属固位体的空间创造仍然存在争议。目的.本临床研究的目的是调查的咬合力和咬合接触重建的RBFPDPs粘固在一个增加的咬合垂直尺寸（Dahl的概念），并评估影响他们的因素。在Teknologi MARA大学牙科学院，对28名接受悬臂式RBFPDPs的参与者进行了一项前瞻性临床研究。最大咬合力记录在precementation，postcementation，和12周的审查访问使用压力指示膜，而咬合接触重建进行了评估，在precementation阶段和12周的审查访问使用垫片股票箔。采用Wilcoxon符号秩和卡方检验进行统计学分析（α = 0.05）。最大咬合力在粘结前与粘结后之间以及粘结后与12周RBFPDPs复查之间存在显著差异（P.05）。总的来说，咬合力在12周后重新建立，在增加咬合垂直尺寸放置RBFPDPs后，大多数参与者完全重新建立咬合接触。
Statement of problem. Space creation for a metal retainer of the resin-bonded fixed partial dental prostheses (RBFPDPs) with the Dahl concept remains controversial because of the lack of clinical studies. Purpose. The purpose of this clinical study was to investigate the occlusal force and occlusal contact reestablishment of RBFPDPs cemented at an increased occlusal vertical dimension (the Dahl concept) and to evaluate the factors affecting them.Material and methods. A prospective clinical study was carried out on 28 participants receiving cantilevered RBFPDPs at an increased occlusal vertical dimension at the Faculty of Dentistry, University Teknologi MARA. Maximum occlusal forces were recorded at precementation, postcementation, and 12-week review visit by using pressure indicating film, while occlusal contact reestablishment was assessed at the precementation stage and 12-week review visit by using shim stock foils. The Wilcoxon signed-rank and chi-squared tests were used for statistical analysis (alpha=.05).Results. Significant differences were found for maximum occlusal force between the precementation and the postcementation and between the postcementation and the 12-week review of RBFPDPs (P.05).Conclusions. Overall, occlusal force was reestablished after 12 weeks, and occlusal contact was completely reestablished in most participants after placement of RBFPDPs at an increased occlusal vertical dimension.
