Neumatización del seno maxilar en mayores de 50 años por pérdida de estructuras dentales

ABSTRACT: The intimate relationship of the maxillary sinus with the dental roots of the upper posterior sector of the maxilla usually has several implications, one of which is pneumatization of the sinus, which occurs with the premature loss of teeth followed by the lack of prosthetic rehabilitation. The objective of this study was to estimate the pneumatization of the maxillary sinus after the loss of a dental organ in patients over 50 years. The present investigation was descriptive, of mixed approach and cross-sectional, 121 cone beam computed tomography (CBCT) scans were observed and 29 were selected according to the established criteria; the area from second premolars to second molars was analyzed where the height of the maxillary sinus was measured, from a fixed guide point was taken the floor of the nasal cavity to the lowest point of the maxillary sinus floor of the edentulous side and the contralateral dentate side; the difference of these values was the estimated pneumatization, the residual alveolar ridge was also measured according to Carl Misch and the molar associated with this phenomenon was established. The results showed that: the edentulous side presented greater maxillary sinus height 6.0986 ±2.67117 than the dentate side, with respect to the residual alveolar ridge 38% of the sample presented Misch grade III and the molar most associated with pneumatization was the second molar followed by the first molar; it was concluded that the estimated pneumatization was 2.92 mm of the population studied.
