Abstract

Abstract: Objective: To measure the potential bone quantity harvested from the anterior nasal spine area by CBCT three-dimensional(3D) reconstruction, and to provide reference for the clinical application of the area as a site for autogenous bone harvesting. Methods: The CBCT data of 300 cases were imported into Mimics software. According to gender, age, and nasopalatine canal, the related parameters were statistically analyzed.Results: The potential bone volumes of the area in men and women were (377.05±115.69)mm³and (334.33±109.75)mm³, respectively (P<0.05). The potential bone volumes of the young group, middle-aged group, and elderly group were (331.70±101.51)mm³, (371.26±122.64)mm³,and (375.46±118.05)mm³, respectively. The volumes of middle-aged group and the elderly group were larger than that of young group (P<0.05). The potential bone volumes of the funnel-shaped group, hourglass-shaped group, cylindrical group, and spindle-shaped group were (321.83±119.28)mm³, (391.44±117.21)mm³, (353.03±108.44)mm³,and (344.09±103.24)mm³, respectively. The volume of hourglass-shaped group was larger than those of other three groups (P<0.05). Conclusion: The anterior nasal spine area can be used as autogenous bone harvesting site for bone augmentation in the upper anterior teeth area. Preoperative CBCT 3D reconstruction can be used to measure and evaluate the potential bone quantity.
