A METHOD FOR MALOCCLUSION FINITE ELEMENT ANALYSIS MODEL

摘要

PURPOSE: A finite element analyzing method of a malocclusion model is provided to track an accurate and expected moving path on various clinical cases by confirming deformation and first power applied to a bracket and a wire through the analysis of tooth movement through tooth moving vectors and orthodontics power applied to tooth generated when the tooth are moved by the restitution of a wire. CONSTITUTION: A finite element analyzing method of a malocclusion model comprises as follows. (a) An upper jaw member, a lower jaw member, and a wire attached to the upper jaw member and the lower jaw member which are malocclusion are three-dimensionally modeled (S10). (b) Material information of the upper jaw member and the lower jaw member, and the wire is set (S20). (c) Control conditions of the upper jaw member, the lower jaw member, and the wire are set (S30). (d) A reaction force of the wire is obtained through the analysis of movement rates of the wire in which the control conditions are set (S40). (e) Each tooth movement of the upper jaw member and the lower jaw member is obtained with the obtained reaction force (S50).
