TL;DR
This study uses computer modeling to show how force, angle, and depth affect the stress and stability of orthodontic mini-implants.
Contribution
A finite element analysis reveals how biomechanical parameters influence orthodontic mini-implant stability and stress distribution.
Findings
Stress and strain in implants increase with higher forces, reaching critical levels above 9 N.
A 60° loading direction reduces implant bending and strain compared to other angles.
Deeper insertion (2–4 mm) improves primary stability by reducing strain and displacement.
Abstract
Background/Objectives: This study evaluated the influence of key biomechanical parameters—orthodontic force magnitude, loading direction, and insertion depth—on stress and strain distribution in orthodontic mini-implants using three-dimensional finite element analysis (FEM). Methods: A three-dimensional model of a titanium orthodontic mini-implant inserted into a mandibular bone segment was developed and analyzed under varying force magnitudes (1–10 N), loading directions (30°, 45°, and 60°), and insertion depths (2–4 mm). Cortical and cancellous bone components were included, and static loading conditions were applied using simplified, linear elastic material assumptions. Results: Stress and strain levels increased with higher force magnitudes, with implant stresses approaching critical values at loads above 9 N. Cortical bone stresses remained within physiological limits, whereas…
