A national survey on retainer preferences and regimens among orthodontists in Malaysia

Abstract Objectives To identify the types of retainers used, their frequency, factors influencing retainer choice, and variations in treatment regimens among Malaysian orthodontists. Methods A questionnaire was developed and validated for content and face validity. The online questionnaire was distributed to orthodontists registered with the Malaysian Association of Orthodontists (MAO) and/or the Malaysian Dental Council under the National Specialist Register (NSR). Results The survey yielded a 43.2% response rate. Vacuum-formed retainers (VFRs) were the most frequently prescribed and preferred retainers for both maxillary (91.1%) and mandibular arches (92.4%). Traditional removable retainers (TRRs), dual retainers, and fixed retainers followed. The primary factor influencing retainer choice is the type of case (93.7%). The prevailing retention regimen for the first six months is full-time wear (64.1%). Most orthodontists prefer night-time wear for 6 to 12 months (87.2%) and for 12 to 24 months (66.7%) post-treatment. Nearly half of the respondents (51.3%) prescribed an appliance retention wear regimen of two to three times per week after 24 months, continuing indefinitely thereafter. Most orthodontists conducted face-to-face follow-ups for 1 to 2 years post-debonding. Conclusion Malaysian orthodontists prefer VFRs in both maxillary and mandibular arches, especially among younger practitioners. Fixed retainers are the least popular. This study provides valuable insight into the retention practices of Malaysian orthodontists.
