# Application of a 3D fusion model to evaluate the efficacy of clear aligners: A clinical study

## TL;DR

This study uses a 3D fusion model to assess how well clear aligners move teeth, finding it effective for some movements but less so for others.

## Contribution

The study introduces a 3D fusion model to evaluate clear aligner efficacy in a clinical setting.

## Key findings

- Mesiodistal and vertical tooth movements had minimal discrepancies (mean <1 mm).
- Rotation, angulation, and torque showed significant deviations in over 40% of teeth.
- The 3D fusion model improves accuracy in identifying movement-specific discrepancies.

## Abstract

Clear aligners have become a popular orthodontic treatment alternative due to their aesthetic and hygienic advantages. A prospective
clinical research was conducted on 30 patients undergoing aligner therapy. Mesiodistal and vertical movements showed minimal discrepancy
(mean <1 mm), with no significant differences. However, rotation, angulation and torque demonstrated significant deviations (p < 0.05),
with over 40% of teeth showing severe discrepancies in these categories. A 3D fusion model enhances clinical accuracy by identifying
movement-specific discrepancies, aiding in treatment planning and refinements.
