Anterior Openbite Malocclusions in Adults: Recommendations, Treatment, and Stability
Almost all research on AOB treatment and stability is from retrospective case series. Therefore, this study has tremendous potential to provide practitioners with stronger evidence about AOB treatment outcomes and stability for adults. It will also provide information about retention outcomes. Additionally, the gathering of patient-reported data about the decision to pursue a specific treatment option and patient satisfaction after treatment may be extremely valuable.
This is a prospective, observational 3.5 year cohort study of approximately 840 adult patients in active orthodontic treatment for AOB who expect to have treatment completed within 24 months of enrollment into the study from approximately 210 National Dental PBRN orthodontists or dentists who routinely perform orthodontic treatment.
The primary objective is to estimate the proportion of patients 1) treated successfully (determined at the end of active treatment), and 2) whose treatment is stable (determined at one year post-active treatment).
The primary outcome measure to determine success of treatment will be overbite at the end of treatment, and the primary measure to determine the stability of treatment ascertained one year after removal of orthodontic appliances is the overbite measurement.
