Analysis of clinical results of micro-screw implant anchorage in treatment of orthodontics

Objective To investigate the clinical effects of micro-screw implant anchorage in treatment of orthodontics.Methods Diagnostic criteria for selecting hospital 50 cases of the wrong jaw deformity patients,randomized into study group and control group,each 25 patients.Study group received treatment micro-screw implant anchorage and the control group with non-implant anchorage is strong anchorage extraoral bow treatment,the whole story are two groups were taken in the treatment of lateral head positioning,analyzed the X-ray cephalometry and compared group methods in orthodontic anchorage in the clinical effect.Results By comparison,the study group total effective rate was 96%,efficacy was significantly better than the control group,64%,(P0.05);Study group the incidence of complications such as root resorption was 30% higher than the 21%(P0.05),study group underwent micro-screw implant anchorage treatment,and convex on the angle from the central incisor as U1/SN(on the central incisor-SN angle),L1/MP(lower central incisor-MP plane angle),U1-L1(on-under the central incisor angle),NLA(nasolabial angle),UIE-OTV(the upper incisors to the PTV margin vertical distance),LIA-PTV(PTV lower incisor tip to the vertical distance),U6-PTV(maxillary first molar buccal tip vertical distance between PTV) and X-ray cephalometry reduction targets significantly more than the control group,the difference was statistically significant(P0.05).Conclusions Micro-screw implant anchorage in orthodontics in a significant effect,but either have a certain rate of occurrence of root resorption,its effect was significantly better than non-orthodontic implant anchorage,worthy of clinical use.
