Thermo-Mechanical Modeling of Orthodontic Tooth Movement

In this paper, a numerical analysis of the human premolartooth and the surrounding tissues was accomplished that itcontains mechanical and thermal phases. For connectingtissue, PDL, a nonlinear stress-strain relation and nonlinearstress-time relation were exerted. It is argued that cellaccumulation is in conjunction with a transient thermal heatflux that its variation follows the compressive stressvariation in the PDL and its value was quantified by using aunique coefficient called thermo-mechanical coefficient.Results demonstrated that the highest temperature rise about1.7°C on the interface of the PDL and the bone was aconsequence of the thermo-mechanical coefficient equal to6 in the thermal analysis while a 2.0N force was applied tothe topmost point of force application and compressivestress was obtained 0.81MPa.
