Abstract The present study applied a three-dimensional (3D) program to measure the distances from the maxillary sinus floor (MSF) to the lingual and buccal alveolar bone and also to the posterior superior alveolar foramen (PSAF), with the aim of determining differences according to gender. The study also attempted to verify the accuracy of measurements obtained from 3D images by performing comparisons with the results obtained in a preliminary study. The results showed that the alveolar bone length and the MAF–PSAF were generally larger in males than in females. It is also predicted that the accuracy of data obtained from a 3D program will be higher than that of data derived from conventional two-dimensional (2D) images. The accurate measurements obtained in this study are anticipated to prove useful in assessments related to dental implantation and anatomical structures. The fundamental data obtained in this study may also assist in setting the goals of future studies utilizing 3D programs.

Introduction The maxillary sinus is the largest of the paranasal sinuses, and is located centrally between the two lateral sides of the cranial bone [1]. Its proximity to the teeth means that the maxillary sinus is a structure of considerable interest in clinical practice [16]. In particular, the closeness of the root and the layer of the maxillary sinus when treating maxillary molars may occasionally cause sinusitis or other infections [2], and hence this spatial relationship needs to be considered in clinical practice [13]. Moreover, the success rate of dental implantation as a common procedure upon tooth agenesis [3] depends on the amount of alveolar bone [12], * Jong‑Tae Park [email protected] Jeong‑Hyun Lee [email protected] Hyun‑na Ahn [email protected] 1

which highlights the importance of postextraction assessments of the length of residual alveolar bone. However, previous studies of the alveolar bone and maxillary sinus have been inadequate. Furthermore, in cases of severe alveolar bone loss involving maxillary molars, maxillary sinus floor (MSF) augmentation may be performed for bone grafting, and complications such as perforation, hematoma, and hemorrhage occur frequently during MSF augmentation [5, 10]. The posterior superior alveolar artery (PSAA) is positioned along the walls of the maxillary sinus [8], where it branches toward the teeth [17], and so also needs to be consid
