Delayed retraction utilizing ceramic brackets.
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.
