Overview

Randomized trial evaluates optimal intrusive force for periodontally compromised teeth, suggesting safer orthodontic practices.

Key Points

  • This study aims to determine the optimal force for intruding periodontally compromised maxillary anterior teeth using finite element analysis.
  • Created a 3D finite element model of maxillary anterior dentition with healthy and compromised sections.
  • Applied a 15 g intrusive force to compare stress distribution between healthy and compromised dentition.
  • Reduced force on the compromised side until stress levels matched those of the healthy periodontium.
  • The compromised periodontium exhibited higher stress and displacement than the healthy side at a 15 g force.
  • Reducing the force to 13.4 g per tooth resulted in stress levels comparable to the healthy periodontium.
  • An optimal intrusive force of 13.4 g per tooth maintains safe stress levels on compromised tissues.
