ABSTRACT
The precise volume of the maxillary sinus is crucial in placing the dental implant in the posterior maxilla region. A radiograph is needed for the preoperative assessment of dental implants. Several radiographs have been used in dental medicine. Lately, cone-beam computed tomography (CBCT) is a 3D dental radiograph used widely. CBCT has overcome the disadvantages of 2D imaging such as high image quality, no distortion, and no superimposition of surrounding anatomical structures. The implant planning software (i-Dixel) was used to consider the implant planning area and volume of the osseous maxillary sinuses, as well as the remaining pneumatized cavities in cases of obliterated sinuses. 100 maxillary sinuses (50 CBCT radiographs) were examined. The average bilateral MSV was 17.70 ± 5.006. The mean right and left MSVs were 17.66 ± 4.965 cm3 and 17.76 ± 5.097 cm3. According to the obtained results, there was no statistically significant difference between the right and left maxillary sinus volume (MSV) (P = 0.865), and the MSV was significantly higher in males than in females (P>0.05). Our study also showed that the volume of the maxillary sinus goes up with age. No significant difference was observed between the age group (p>0.05). 3D examination of the maxillary sinus can be done through CBCT. Even in the same person, there was a difference in the volume of the maxillary sinuses on the left and right. Nevertheless, no statistically significant was observed. The CBCT should be considered while examining the maxillary sinus area.
