Duruel O, et al. - This retrospective study was conducted by researchers to inform topography of posterior superior alveolar artery (PSAA) and to assess measurements of this vital structure. For this investigation, they assessed 354 cone-beam computed tomography (CBCT) images of PSAA from 177 patients (mean age was 54.05 ± 18.33 years). For all posterior teeth, the PSAA diameter was frequently measured below 1 mm. While palatal bone thickness in the premolar region was higher than molars, there was no statistical relationship between tooth region and buccal bone thickness. Residual ridge width was measured both wider apically and posteriorly. In the first molar and premolar regions, there was a positive correlation between buccal bone thickness and PSAA diameter. Overall, the investigators suggested that CBCT's detailed assessment of patients gave us the opportunity to draw PSAA topography and provide information on overall PSAA measurements in all posterior teeth regions.
