摘要：The aim of this prospective study was to investigate radiologic and clinical factors associated with increased difficulty in the removal of impacted maxillary canines. And to form an index to measure the difficulty of removal of the impacted maxillary canines preoperatively. Materials and methods: A total of 40 patients who required surgical extractions of impacted maxillary canines betweenOctober 2020 and October2021 were involved in the study. Radiologic and clinical data were taken preoperatively. All extractions were performed under local anesthesia by a single operator. The surgical difficulty was measured by the total intervention time Results: The increased surgical difficulty was associated with increasing age and body mass index. It was also associated with the curvature of the roots of the impacted tooth and the depth from point of elevation (P >0.05) Conclusions: Both clinical and radiologic variables are important in predicting surgical difficulty in impacted maxillary canine extractions. We tried to make CBCTa standard means and assess the difficulty of canine extraction in relation to root curvature, incisor overlap, and angulation of canine with lateral incisor but clinically there were differences are been appreciated and leading tothe form of a new index.
