Abstract
Objective:To study the application value of spiral CT three-dimensional reconstruction technology in plastic mandibular malformation. Method:From March,2012 to March,2013,18 cases of mandibular malformation patients admitted in March,the spiral CT scanning and three-dimensional reconstruction, vertical measurement was done on maxillofacial first molars,the second premolars,the distance to the edge of mandibular second molars and the distance of mandibular central branch to mandibular angle,and the distance among the normal,malformation before operation and malformation after operation were compared. Result:Maxillofacial first molars,the second premolars,the distance to the edge of mandibular second molars and the distance of mandibular central branch to mandibular angle of the normal side and malformation before operation was compared,with significant difference and with statistical significance(P<0.05). There was no statistical meaning between normal side and malformation side after operation. Conclusion:Mandibular deformities in the plastic using spiral CT 3 d reconstruction technology can accurately judge the surgical site,accurate measurement osteotomy,to assure the safety of surgery and smoothly,and it has great application value.关键词
