Abstract
The belief that close adaptation of the metal margins to tooth surfaces in the undercut areas is the most important retentive feature, was borne out in this study. The type of preparation did not affect the retention of stainless steel crowns.
摘要
本研究证实了这样一种观点，即金属边缘与倒凹区域牙齿表面的紧密贴合是最重要的固位特征。预备类型不影响不锈钢冠的固位。
