The aim of the current study was to evaluate the accuracy of computer-guided mandibular fracture reduction. A total of 24 patients with fractured mandible were included in the current study. A preoperative cone beam computed tomography (CBCT) scan was performed on all of the patients. Based on CBCT, three-dimensional reconstruction and virtual reduction of the mandibular fracture segments were done and a virtual bone borne surgical guide was designed and exported as Standard Tessellation Language file. A physical guide was then fabricated using a three-dimensional printing machine. Open reduction and internal fixation was done for all of the patients and the fracture segments were anatomically reduced with the aid of the custom-fabricated surgical guide. Postoperative CBCT was performed after 7 days and results of which were compared with the virtually reduced preoperative mandibular models. Comparison of values of lingula-sagittal plane, inferior border-sagittal plane, and anteroposterior measurements revealed no statistically significant differences between the virtual and the clinically reduced CBCT models. Based on the results of the current study, computer-based surgical guide aid in obtaining accurate anatomical reduction of the displaced mandibular fractured segments. Moreover, the computer-based surgical guides were found to be beneficial in reducing fractures of completely and partially edentulous mandibles.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
