Evaluation of the Perceived Experience of Patients Treated With Aligners With Two Different Timings

Recruiting now · Not applicable

Conditions studied: Malocclusion

In brief

The primary aim of the study is to compare the perception of pain and discomfort with two different protocols of attachments' placement during clear aligner therapy: the conventional protocol (CP), when attachments' placement is performed are placed at the delivery of the first aligner; the delayed protocol (DP), when the attachments' placement is performed at the delivery of the third aligner. The rationale of this study is to evaluate whether dividing the two phases most associated with the onset of pain and discomfort, namely the initiation of aligner therapy and the placement of attachments, can improve patients' quality of life during clear aligner treatment. Patients' discomfort will be evaluated with a questionnaire adapted by OHIP-14 (Oral Health Impact Profile 14)
