The aim of this study will be to evaluate the biological reaction of direct three dimensional printed retainers.
Primary objective is to evaluate bacterial growth and color stability between different thicknesses of 3d printed material used as a retainer .
Secondary objective is to determine the optimal thickness for use in clear aligner fabrication based on biological performance.
-Finished fixed orthodontic therapy and seeking for retention as a part of their original treatment plan.
