Title: Correcting crowding of mandibular teeth by implant anchorage and partial arch wire for adult
Abstract: Objective To evaluate clinical effects and the characters by micro-implant anchorage and partial arch ware correcting crowding of mandibular teeth in Class I malocclusal patients.Methods 24 Micro-implants were embedded buccal bone of mandibular first molar and mandibular second premolar of 12 Angle I malocclusal patients Ni-Ti coil spring was connected to implant and hook of distalization of mandibular lateral incisor so as to close space by contracting mandibular preteeth.Measuring buccolingual position changes of mandibular central incisors,compaction,angle of mesiodistal inclination,and moving velocity,root obsorbsion and periodontal membrane change.Evaluating anchorage by the change of mandibular first molar.Results Mandibular central incisor:lingual movement and lingual inclination was 1.6mm,4.5 degree,compaction was 0.5mm,no mesiodistal inclination.course of treatment was 3.2 months,velocity of mandibular central incisor.No root obsorbsion and periodontal membrane change.Location of mandibular first molar was no changetable.Conclusion The problem of teeth crowding was resolved successfully,location of mandibualr molar and occlusion of posterion tooth was no changeable.
