Preoperative Cone Beam Computed Tomography Assessment of Intraoral Autogenous Bone Graft Volumes Linked to Sex and Tooth Condition

BACKGROUND This study aimed to evaluate preoperative donor site graft volume according to sex, donor site, and tooth impaction in 100 patients using cone beam computed tomography (CBCT). MATERIAL AND METHODS Using CBCT images, the graft volume that could be taken from the donor site was measured according to the presence of impacted third molars and tooth deficiency. Ramus, symphysis, and tuber regions, which are the areas from which intra-oral grafts can be taken, were left a safe distance from the right and left anatomical formations and tooth roots. The relevant area was marked semi-automatically and volume calculation was made with the IRYS 15.1 software program. Analysis of variance (ANOVA) and Kruskal-Wallis test were used in the analysis. RESULTS This study included 51 (51%) males and 49 (49%) females, for a total of 100 individuals, with an mean age of 37.06±14.29. Maximum potential graft volume was highest at the right symphysis and lowest at the right maxillary tuber. A significant difference was found between regional intra-oral graft volumes (p<0.05). When the presence and absence of impacted third molars were compared, a significant difference was observed in regional graft volumes (p<0.05). CONCLUSIONS More autogenous grafts can be obtained from the symphysis region in males than in females. Pre-measurement of donor site intra-oral graft volume prevents unnecessary surgical procedures.
