Abstract: This study aimed to develop a specification of the subantral bone loss. Materials and methods: We performed a monocentric, retrospective study of 76 preoperative cone-beam computed tomography (CBCT) images of patients who underwent maxillary sinus floor augmentation (MSFA) procedure with lateral approach between 2014 and 2021. A total of 108 sinuses with 305 missing teeth regions were observed. Results: Subantral bone height (SBH) decreased from premolar (10, 80 mm ? 3, 31 mm) to molar region, subantral bone width (SBW) and maxillary sinus width (MSW) increased from premolar (6, 27 mm ? 2, 07 mm and 5, 98 mm ? 2, 31 mm) to molar region (8, 50 mm ? 2, 78mm and 11, 40 mm ? 2, 95mm). Differences estimatedby Kruskal-Wallis analysis p<0.0001 are statistically reliable. It was established significant inverse relation between MSW u SBH p< 0, 01. There was a significant direct relation between MSW and SBW p<0, 01. Conclusion: Our study describes the trends in the sizes of SBH, SBW and MSW. We believe that our results could be helpful for future clinical researches to establish a relationship between SBW and MSFA procedure success, as there are already studies looking for a relation between MSWand MSFA success.
