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.
