This study aimed to evaluate the knowledge of senior dental students about mouth preparation and removable partial denture (RPD) design. Two hundred sixty-six senior students from eleven dental schools in the State of São Paulo, Brazil, comprised the sample. The subjects examined two partially edentulous casts mounted on a semiadjustable articulator, answered a questionnaire regarding the treatment plan, and drew the RPD design. The casts consisted of Kennedy Class III, modification 1 maxillary arch and Class II mandibular arch. Ninety percent of the students believed that mouth preparation should be performed although no one was able to name all necessary procedures. For the maxillary arch, 12 percent of the denture designs were completely appropriate, 51 percent were partially appropriate, and 37 percent were inappropriate. For the mandibular arch, the results were 3 percent, 40 percent, and 57 percent, respectively.
本研究旨在评估高年级牙科学学生对口腔预备和可摘局部义齿（RPD）设计的了解。来自巴西圣保罗州 11 所牙科学院的 266 名高年级学生组成了样本。受试者检查了两个安装在半可调架上的部分无牙颌模型，回答了关于治疗计划的问卷，并绘制了 RPD 设计。这些模型由 Kennedy 类 III、改良 1 上颌弓和 II 类下颌弓组成。90%的学生认为应该进行口腔预备，但没有人能够说出所有必要的程序。对于上颌弓，12%的义齿设计完全合适，51%部分合适，37%不合适。对于下颌弓，结果分别为 3%、40%和 57%。
