Objective To explore the clinical application and observe the effects of micro-implant anchorage in orthodontics study. Methods 74 cases of children patients were randomly divided into experimental group（n=38） and control group（n=36） ,control group were given non-implant strong anchorage therapy,and experimental group were given Micro-Implant Anchorage therapy. Results Experimental group was signif icantly higher than control group in reduction of upper incisor inclination and distance. Another hand,Experimental group was signif icantly lower than control group in displacement of molars. We can conclude that experimental group was signif icantly better than control group. Conclusion Micro-implant can provide satisf ied anchorage orthodontics therapy,and it has many advantages in handling and stability,so it deserved application and promotion in clinical work.
