Abstract Purpose This study aims to analyze alveolar bone height (ABH) in the maxillary molar area according to the anatomical relationship between maxillary sinus and maxillary molar teeth via cone beam computed tomography images. Methods In 330 patients, 660 maxillary first molar (M1) and 648 maxillary second molar (M2) were evaluated. ABH measurements were made as to the shortest distance between the furcation midpoints of maxillary molars and the lowest point of the sinus floor. After the measurement, the positions of the maxillary molar teeth relative to the maxillary sinus were classified into four categories as type 1, 2, 3, and 4. Results ABH measurements in males were significantly higher than females (p < 0.05), but there were no differences between sides (p > 0.05). There were significant differences between types of both M1 and M2 for ABH, and the longest ABH was measured in type 1 (p < 0.05). Type 3 was the most common among 1308 maxillary molars teeth followed by type 1, type 2, and type 4. Conclusion Determination of the relationship between maxillary molar teeth and the maxillary sinus and analysis of ABH according to this relationship may help plan endodontic treatment, apical surgery, and immediate implant therapy and prevent their complications.

Introduction The maxillary sinus is a bilateral anatomical structure that differs from person to person in the shape, position, and dimensions which is located in the midface of the skull [1]. The curved structure, called the maxillary sinus floor, usually consists of a thin cortical bone or a mucous layer [2, 3]. Due to the proximity between maxillary sinus floor and molar teeth roots, complications such as the spread of periodontal and periapical infections to the sinus, pushing of the root canal filling materials to the sinus, or formation of an oroantral fistula after * Ceren Aktuna Belgin [email protected] 1

implant treatment or tooth extraction may occur [4, 5]. Therefore, it is of clinical importance to know the anatomical relationship between the maxillary sinus and molar roots in diagnosis and treatment planning in the posterior maxilla. Implant treatment is widely used in edentulous patients in dentistry. Immediate implant treatment, which is the implant placed in the fresh extraction socket following a tooth extraction, has many
