Background: Peri-implant biofilm formation due to local bacterial colonization is one of the important factors for the instability of temporary anchorage devices (TADs).
Aim: The aim of this study was to quantify and compare the colonization of on ultraviolet (UV) treated and untreated titanium TADs.
Materials And Methods: This prospective, study included 20 subjects requiring orthodontic treatment with first premolar extraction, followed by retraction of the anterior teeth with absolute anchorage using TADs.
