Abstract
  • The purpose of this research is to develop a virtual, orthodontic, continuous archwire model for assessing a lingual bracket system. A digital model of a maxilla, periodontal ligament, and dentition was constructed from human computed tomography data. Virtual lingual and facial brackets were placed on the maxillary left central incisor through first premolar. An intrusive tooth movement was utilized to test the model and compare labial and lingual biomechanics. The ANSYS 13.0 birth-death function simulated force interaction between the wire and brackets. The goal of placing labial and lingual bracket-wire systems on accurate anatomy including multiple teeth was achieved. Material property definitions had an effect on a finite element model. The birth-death computer technique simulated the clinical effects of placing an archwire in brackets and allowing forces to be transferred from the bracket-wire system to the surrounding dental structures. The lingual appliance has different biomechanical effects than the labial appliance.
