ABSTRACT

Introduction: In order to avoid complications, it is essential for surgeons to have a detailed knowledge of the anatomy of the superior maxillary bone prior to performing any sinus lift procedure. The alveolar antral artery forms an intraosseous anastomosis with the infraorbital artery at the level of the anterolateral wall of the maxillary antrum at an approximate distance of between 18.9 and 19.6 mm from the maxillary alveolar ridge. The alveolar antral artery is responsible for providing vascularity to the mucous membrane of the maxillary sinus, the anterior lateral wall of the sinus, and the underlying periosteal tissue. Objective: To analyze and establish the frequency, diameter, and location of the anastomosis between the infraorbital artery and the posterior superior alveolar artery known as the alveolar antral artery, and its relationship to the alveolar bone crest in a Mexican cohort. Material and methods. We conducted a cross-sectional observational descriptive study involving a cohort comprised of 1,116 patients of the Institute for Social Security and Services for State Workers (ISSSTE) on the east side of Mexico City. The study consisted of a review of CBCT studies. Results: The arterial anastomosis was found in 90% of the 1,005 CBCT studies reviewed, based on which the following values were determined for the distance between the alveolar ridge and the canal of the alveolar antral artery: for the first premolar, 18.24 mm; second premolar, 17.35 mm; first molar, 16.96 mm, and for the second molar, 18.75 mm. Conclusions: We established the average measurements for the location of the vascular bundle in question and the measurements needed to safeguard it along its course, which is important for the preservation and osseointegration of bone grafts placed during maxillary sinus lift procedures, thus providing a margin of safety not previously reported in the literature for a Mexican cohort.
