Resumo
Objective: The main objective is to provide information from an anatomical point of view. To evaluate the prevalence, diameter and position of the superior posterior alveolar artery (SPAA), its relationship with the alveolar crest and the floor of the maxillary sinus using radiographic images. Materials and methods: A total of thirtytwo cone beam computer tomography (CBCT) images (forty-one maxillary sinuses in total) of partially edentulous patients in the posterior maxilla, of which twenty-three are women and nine men, that have been submitted in the University Clinic of the European University of Madrid. Three types of CBCT scanners are used: KODAK 9000, MORITA 3D and White Fox-Control D-00049. Results: The superior posterior alveolar artery has a visibility percentage of 43.91%, it is located at a height of 15.9 mm on average from the bone crest, in the groups of 1-2 mm and <1 mm in diameter they respectively obtain 1, 2 mm and 0.7 mm of average values and positioned in 21.13% intraosseous and 22.76% extraosseous. Conclusions: In our study, the PSAA presents a distance to the alveolar crest from higher to lower residual height, first the second premolars, then the second molars, and finally the first molars. In other words, it makes an arc-shaped path, making the maximum concavity at the level of the first molar.
