Preparations maintaining the greatest amount of buccal and lingual tooth structure were the most retentive. Cement significantly increased the retention capacity of all preparations. Mechanical retention did not contribute significantly to the separation-resistance of the stainless steel crown. Factors other than retention may be of greater importance to the clinical success of stainless steel crowns.
