This study was conducted to clarify the degree to which a master cast needs to be carved to obtain a posterior palatal seal according to Swenson, based on a comparison among four dental practitioners. Sections of the casts with the seal scraped were made, and an optical microscope was used to measure the sagittal and vertical dimensions. It was found that the sagittal dimension may show a smaller difference in carving of the master cast in the posterior palatal seal area. The present results also suggest that the clinical experience of the prosthodontist in applying this method seems to have an effect on the carved shape and depth of the posterior palatal seal.
本研究旨在通过比较四位牙科医生，阐明根据斯文森法制作主模型时，为获得后腭部封闭区需要雕刻的程度。制作了刮除封闭区的模型切片，并使用光学显微镜测量矢状和垂直尺寸。结果发现，在主模型后腭部封闭区的雕刻中，矢状尺寸的差异可能较小。目前的结果还表明，修复医生应用此方法的临床经验似乎会对后腭部封闭区的雕刻形状和深度产生影响。
