Abstract

Objectives: The purpose of the study was to use FEM to analyze three dimensional movements of first permanent molar distalization using mini-implants.

Aim of the Study: The aim of the study was to analyze the FEM model of the maxilla which simulates the three dimensional movements of the first permanent molar after distalization using mini-implants.

Materials and Methods: In the present study, a 3D FEM model of right maxilla with an end on molar relation was created and was used to calculate the amount of distalization in three axes, when forces were applied on implant to distalize the molar.

Results: On buccal side, the molar showed mesial buccal rotation, intrusion with uncontrolled distal tipping on application of 150 gms, on application of 200 gms, the molar showed mesial buccal rotation, intrusion with uncontrolled distal tipping and extrusion of mesial cusps. On palatal side, the molar showed mesio palatal rotation, distal displacement, and intrusion of distal cusps and extrusion of mesial cusps which were the same on application of 150 and 200 gms of force, but the movements were more with the latter.

Interpretation and Conclusion: Buccal placement leads to distalization and unwanted tipping, whereas palatal placement shows more distalization and less tipping, as it is closer to center of resistance. In terms of visibility and ease of placement, buccal implant was easier compared to palatal implant.
