Abstract

Which Type of Functional Appliance Should We Use?

by Johal Ama

This presentation will present the findings of a randomized clinical trial and Qualitative study comparing the use of fixed [Hanks-Herbst] and removable [Twin Block] functional appliances. The research presents a unique perspective of both clinician-centred and patient-centred outcome measures. In a further attempt to better understand our patient's experience with both the removable and fixed fuctional appliances, in-depth one-one semi-structured interviews, involving a purposive homogeneous sampling technique, was applied. The RCT findings report on the effectiveness of the appliances in reducing the overjet, their timings and the skeletal and dental effects. A range of validated patient questionnaire findings are also reported alongside the complications. The qualitative study outcomes are based on interviews of patients using each type of functional appliance and a failed twin block group treated with the fixed functional. The findings will offer clinician's a real perspective of how our patient's tolerate these appliances and importantly their preferences, as well presenting the results of their clinical effectiveness.
