? 2022 American Association of OrthodontistsIntroduction: This study aimed to survey retention protocols and retainer characteristics among orthodontists practicing in Canada. Methods: An online questionnaire was distributed to 576 orthodontists registered with the Canadian Association of Orthodontists. It included respondents’ demographic details, preferred orthodontic retainers and prescribed wear protocol, adjunctive retention procedures, the timing of retention follow-ups, retainer choice in specific situations, and retainer characteristics. Chi-square tests and Fisher's exact tests were used to test the associations between variables. Results: An 18% response rate was recorded (n = 101). Vacuum-formed retainers were the most commonly used retainers in the maxilla (50.5%), whereas bonded retainers were preferred in the mandible (54.5%). An initial full-time removable retainer wear period was commonly prescribed (63.0%-67.0%). Retainer checks were carried out by 85.1%-89.1% of orthodontists for 1 or 2 years after the end of active orthodontic treatment. Only 44.6%-56.4% were comfortable with general dentists continuing retainer checks. Most (72.5%-84.1%) retainers were fabricated in the orthodontists’ office laboratory. Indefinite retainer wear was commonly suggested and was significantly influenced by the number of years in practice. Conclusions: Most orthodontists’ preferred retainer was the vacuum-formed retainers in the maxilla and the bonded retainers in the mandible. A variety of retention protocols and retainer characteristics was evident among orthodontists that reflect the considerable variation in malocclusion traits we face day-to-day. There seems to be a potential dichotomy between orthodontists being uncomfortable about allowing general dental practitioners to manage retention and orthodontists unwilling to provide retention care indefinitely.
