General dental practitioners' training and experience in clear aligner treatment in England: a mixed-methods study

Aims This study explored the training and working experiences of general dental practitioners (GDPs) in England in providing clear aligner treatment (CAT) to adult patients.Methods A mixed methods approach was adopted, including an online questionnaire and semi-structured interviews of GDPs in England providing CAT. Quantitative data were analysed descriptively using MS Excel and qualitative data using framework methodology.Results One hundred completed surveys were received, and 16 interviews were conducted. Most GDPs reported having attained aligner certification (n = 86) and nearly one-third (n = 31) gained some theoretical knowledge of CAT but highlighted key shortcomings of the training courses. GDPs felt confident in treating mild or moderate malocclusion traits and expressed several reasons for choosing a specific CAT and digital scanner and provider. Those GDPs qualified more than ten years could apply complex treatment mechanics. Laboratory-made fixed retainers were of higher preference following CAT, especially in complex malocclusions with high risk of relapse.Conclusions GDPs' limited understanding and diverse practices in CAT provision, suggest the need for policymakers to review the undergraduate dental curriculum and for educators to ensure the inclusion of theoretical and practical aspects of CAT, together with the ongoing support of specialist in orthodontics.
