[Relations between the maxillary sinus and upper maxillary process. Anatomotopographic study].

The anatomic proximity of the antral floor and superior alveolar processes favors the propagation of infections from teeth to neighboring structures, as was pointed out first by John Hunter. A radiologic and anatomic study was made of these anatomic relations and the bony substance between the alveolar ridge and maxillary sinus was measured. No firm criteria for normality could be established because of the variability of the maxillary sinus. Variations in environmental and developmental conditions easily modify its morphology.
