Abstract

Background: Cone Beam Computed Tomography (CBCT) increasingly is a main source of 3D volumetric information in clinical orthodontics. In this study, the maxillary sinus for the presence of the retention cysts in implant patients was evaluated using CBCT.Materials and Methods: CBCT images from 320 patients (168 females and 152 males), who were candidate for implant placement in the maxilla, were selected. The single dome shaped image with the soft tissue density on the floor of the maxillary sinus without the cortical boundary was recognized as the retention cyst. The chi –square test was used for the statistical analysis.Results: maxillary retention cyst was diagnosed in 31 patients (18 females, 13 males). Also, two cases showed the involvement of both sinuses. The incidence was 10.3%, only two patients reported the history of sinusitis. Chi square test did not show any difference between the females and males.Conclusion: We found an incidental rate of 10.3% of retention cysts in the implant patients.
