Direct of indirect plaatsen van een vaste beugel

The aim of this study is to compare direct bracket bonding versus indirect bracket bonding. We will plan the indirect bracket placement in the 3Shape OrthoAnalyzer software and then indirect bonding trays will be printed. Hereby the amount of detached brackets will be considered between the two methods (bonding failures). Further, the fitting accuracy of the indirect bonding trays can be evaluated. Towards the end of this study, positioning inaccuracies of brackets can be identified (positioning failures). Additional to the above mentioned, the patients fill out a questionnaire about oral health related quality of life (OHRQoL) before bonding and after elaboration of a .014 NiTi wire, to see if orthodontics bracket bonding in general has an impact on the OHRQoL. Additional, a couple of supplementary questions about the patient's experience of the two bonding methods are asked just before and after bonding, to get to know which method the patients prefer.

• There is no difference in number of bonding failures between the direct and indirect bracket bonding methods • Patients favour indirect bracket bonding over direct bracket bonding • Brackets bonded with the indirect bracket bonding will have less position failures over brackets bonded with the direct bonding method • The bracket placement accuracy of the used printed indirect bonding trays is sufficient for clinical application • Orthodontic bracket bonding does not influence the OHRQoL
