A method was developed for quantifying morphological characteristics of cavities and restored teeth, in a quest for more knowledge of factors which determine the long clinical success or failure of restorations, and which may therefore be used in making objective assessments of their quality. The method involved obtaining sequential silicone rubber replicas of teeth in vivo, sectioning them in planned planes, and making objective linear and angular measurements directly from X 10 photographs of the resulting profiles and from positive models. It would seem that the method could be applied in a variety of clinical investigations.
开发了一种用于量化龋洞和修复牙齿形态特征的方法，旨在更深入了解决定修复体长期临床成功或失败的因素，这些因素因此可用于对其质量进行客观评估。该方法包括在体内获取牙齿的连续硅橡胶复制品，在预定平面上进行切片，并直接从所得轮廓的X 10照片和正模型进行客观的线性和角度测量。看来该方法可应用于各种临床研究。
