The purpose of this study was to assess the usefulness of saturated salt solution‐embalmed cadavers for oral surgical skills training related to bone graft harvesting. Two half‐day surgical skills training workshops were held at the Tokyo Medical University utilizing eight cadavers embalmed with the saturated salt solution. A total of 22 participants including oral surgeons, residents, and dentists attended the workshop. Surgical training consisted of six procedures related to intraoral and extraoral bone harvesting. The participants were surveyed to assess self‐confidence levels for each surgical procedure before and after completion of each workshop. The Wilcoxon signed‐rank test was used to compare the differences between each median score before and after the workshop. There were statistically significant increases in the self‐assessed confidence scores in bone harvesting procedures for the zygomatic bone (P = 0.003), maxillary tuberosity (P = 0.002), and other sites (P < 0.001). The anatomical features of saturated salt solution‐embalmed cadavers were also examined. The textures of the oral mucosa and skin were similar to those of living individuals. The structure of bone tissues was well‐preserved and the hardness was realistic. Consequently, all procedures were performed with sufficient realism. The saturated salt solution method has a relatively low cost of preparation and storage, and almost no odor. The authors suggest that saturated salt solution‐embalmed cadavers could provide a new model for oral surgical skills training in bone harvesting.

饱和盐溶液防腐方法在口腔外科技能训练中的作用：一种新的尸体采集尸体训练模型。

这项研究的目的是评估饱和盐溶液包裹的尸体在与移植骨相关的口腔外科技能培训中的有用性。在东京医科大学举办了两个半天的外科手术技能培训班，其中使用了八只浸有饱和盐溶液的尸体。共有22位与会人员，包括口腔外科医师，住院医师和牙医。外科手术训练包括与口内和口外骨收集有关的六个程序。在每个讲习班结束之前和之后，对参加者进行调查，以评估每种手术程序的自信心水平。在研讨会之前和之后，使用Wilcoxon符号秩检验来比较每个中位数得分之间的差异。P  = 0.003），上颌结节（P  = 0.002）和其他部位（P  <0.001）。还检查了装有饱和盐溶液的尸体的解剖特征。口腔粘膜和皮肤的质地与活着的个体相似。骨组织的结构保存完好，硬度是现实的。因此，所有过程均以足够的真实感执行。饱和盐溶液法具有较低的制备和储存成本，并且几乎没有气味。作者认为，用饱和盐溶液包裹的尸体可以为骨收集方面的口腔外科技能培训提供新的模型。
