title: Delayed retraction utilizing ceramic brackets.
abstract: The purpose of this study was to evaluate clinically the delay in retraction utilizing ceramic orthodontic brackets versus stainless steel brackets. Twelve patients with Class II division 1 malocclusions requiring the extraction of maxillary first premolars were employed in the study. The following observations were obtained: 1. Retraction of all cuspids bonded with ceramic brackets displayed delayed retraction when compared to their stainless steel counterparts. 2. Over a 36 week period, teeth bonded with stainless steel brackets travelled 2mm farther or 1.8 times faster than those bonded with ceramic brackets.
