Abstract

Abstract: PURPOSE: To investigate the clinical effect of micro screw implant anchorage in the treatment of adult patients with double jaw protrusion. METHODS: A total of 100 adult patients with bimaxillary protrusion were stratified into micro screw implant anchorage group (n=50) and extraoral anchorage group (n=50) according to different treatment methods. The differences of lip protrusion, upper alveolar protrusion and lower alveolar protrusion, dentition,mandible and maxilla were evaluated after treatment. SPSS 19.0 software package was performed for data analysis. RESULTS: The treatment duration of micro screw implant anchorage group and extraoral anchorage group was (18.84±2.61) month and (24.72±2.32) months, respectively, which was significantly different (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 treatment were significant between 2 groups. The differences 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 micro screw implant anchorage group were significantly greater than those in extraoral anchorage group (P<0.05). CONCLUSIONS: The clinical effect of micro screw implant anchorage in the treatment of adult patients with double jaw protrusion deformity is significant, which is worthy of clinical application.
