Abstract

Abstract:

Objective To investigate tooth movement characteristics of maxillary anterior teeth intrusion by three-dimensional finite element analysis with micro-implants implanted in different parts during the treatment of tooth extraction with clear aligners, so as to guide clinical practice. Methods A three-dimensional finite element model was established for the treatment of maxillary first premolar extraction with the clear aligner, and divided into four groups according to the implantation site of the micro-implant including working condition 1(control group without micro-implant), working condition 2(micro-implants implanted between maxillary central incisors), working condition 3(micro-implants implanted between maxillary central incisors and lateral incisors) and working condition 4(micro-implants implanted between maxillary lateral incisors and fangs). The traction force from the micro-implant to the cutting edge of the tongue side of the appliance was applied to analyze the tooth movement characteristics under different working conditions. Results In the first condition, the central incisor and lateral incisor showed oblique movement of the crown to the lingual side and the root to the lip side, while the second premolars to the second molars showed a small movement of the crown to the mesial root, and a small movement of the root to the distal root. In working condition 2 to working condition 4, the anterior tooth area showed depression accompanied by lip tilt movement, while the posterior tooth area showed midpoint crown inclination accompanied by a small amount of depression movement. The pressure of central incisor was in the order of working condition 2>working condition 3>working condition 4; the pressure of lateral incisor was in the order of working condition 3>working condition 4>working condition 2; the pressure of fangs and posterior teeth was in the order of working condition 4>working condition 3>working condition 2. Conclusion Elastic traction with micro-implants in the anterior tooth area can effectively increase the anterior tooth pressure. When the implant site moves back, the molar pressure increases significantly; the distal root movement of the posterior tooth increases, and the effect on anterior tooth lip inclination decreases.
