| Popis: | Introduction: Treatment of Class III malocclusion is a considerable clinical challenge for the orthodontist and commonly includes growth modication involving a chincup to restrain mandibular growth or a facemask to protract the maxilla, dentoalveolar compensation or camouage involving dental extractions, or orthognathic surgery. The present Materials And Methods: study was a Finite Element study. This Study was conducted from 12 months at Department of Orthodontics and Dentofacial Orthopedics, Guru Nanak Institute of Dental Sciences and Research were procured from the departmental archives. Increasing the occlusal inclination of the Result: loading force decreased the compressive stresses on the alveolar bone, but an insignicant increase was produced in the compressive stresses on increasing the gingival inclination of the loading force. On comparing the compressive stresses, the horizontal and the 15 degree occlusal force showed greatest compression in the distal surface in the cervical third close to the midline. The 15 degree gingival force also showed greatest compression in the distal surface in the cervical third but it was spread more buccally. The 30 degree occlusal force also showed greatest compression in the distal surface in the cervical third but it was spread more lingually. We found that, the 30 degree gingival force Conclusion: shows an increased tendency of the tooth to intrude, as evidenced by the compressive stresses produced around the furcation and either apical regions. Increasing the occlusal inclination of the force shows an increased tendency of the tooth to extrude rather than distalize |
