Objective To explore the clinical application of micro screw implant anchorage in orthodontic treatment of patients with bimaxillary protrusion.Methods A total of 62 cases of orthodontic treatment for adult patients with bimaxillary protrusion deformity were divided into micro screw implant anchorage group (group A, 27 cases) and extraoral anchorage group (group B, 35 cases) according to the different treatment methods.Results The orthodontic treatment time in group A was significantly shorter than that in group B (P < 0.05). The difference of upper lip protrusion, lower lip protrusion, upper lip-E line, lower lip-E line and lip gap before and after the treatment in group A were higher than those in group B (P < 0.05). The difference of the upper incisors protrusion, lower incisors protrusion, the upper central incisors angle, the lower central incisors angle, upper alveolar protrusion and lower alveolar protrusion before and after treatment in group A were greater than those in group B (P < 0.05). Conclusion Micro screw implant anchorage provides satisfactory antitumor effect in orthodontic treatment of patients with bimaxillary protrusion than extraoral anchorage, it is worth in the clinical application. |
