种植支抗后牵引猴上颌骨颌面形态变化的实验研究

Abstract

Abstract: Objective To investigate the dentofacial changes caused by retractive force with zygomatic implant anchorage to the maxilla of rhesus monkeys.Methods Three male rhesus monkeys with mixed dentition were randomly assigned to 2 groups： 2 monkeys for experimental group,and 1 for control group.The implants in anterior maxilla were loaded by retractive forces with zygomatic miniplates through NiTi coilsprings.A backward force of 2.94 N was exerted on each side of maxilla for 3 months.Facial characters,model measurements,and Xray cephalometric results were compared before and after treatments.Results The implants kept stable during the whole experiment.The anterior overjet and the length of upper dental arch significantly decreased in experimental group,while the width of upper dental arch increased; SNA and ANB angles reduced and maxillary A point was moved 2mm backward for both monkeys in the experimental group.The angle of palatal plane was increased in both groups,and maxilla rotated clockwise slightly.Conclusions Retracting maxilla with intraoral implant anchorages can inhibit the forward maxillary growth in growing rhesus monkeys,providing experimental basis for a new method of treating maxillary protrusion in mixed dentition.
