Prevalencia de neumatización del seno maxilar en pacientes edéntulos parciales o totales según la clasificación de Carl Misch, diagnosticados mediante CBCT en un centro radiológico privado de la ciudad de Cuenca, 2021 - 2022

Abstract

Highmore's antrum is considered the largest paranasal sinus, located in the body of the maxillary bone. Its pneumatization process is part of its growth and development. After tooth loss, osteoclastic activity begins in Schneider's membrane, which causes the maxillary sinuses to increase in size, a situation that complicates prosthetic rehabilitation and implant placement. Objective: To determine the degree of pneumatic sinus pneumatization based on Carl Misch's classification in partial or edentulous patients treated in a private radiology center in the city of Cuenca diagnosed by CBCT in 2021-2022. Methodology: Study of observational, descriptive, and cross-sectional types. Seventy-three cone-beam tomographic studies of total and partially edentulous patients considering the area from canines to second molars were examined, based on Carl Misch's classification, to determine the degree of pneumatization and the depth of the maxillary sinus. Results: grade III pneumatization was the most prevalent in 43.41% of the total 129 maxillary sinuses evaluated, a grade IV was mostly in total edentulous (17.05%), and partial edentulous a grade III was more predominant (27.13%). Conclusion: The relationship between the degree of pneumatization and the depth of the maxillary sinus was evident, determining that the pneumatization of the sinus is linked to tooth loss, these results may be useful for planning surgical procedures and to take into account possible complications in patients with greater degree of pneumatization.
