Prevalencia de reabsorción ósea del reborde crestal posteroinferior mandibular mediante análisis de escáner CBCT – Guayaquil.

Abstract

Introduction: The alveolar ridge undergoes modifications that cause defects, this can be caused by various factors as the main one is the annual physiological resorption that exists in bone structures if there is no treatment for its preservation, loss of teeth, age, trauma and periodontal disease. Objectives: To establish the prevalence of crestal ridge bone resorption by CBCT scan analysis. Materials and Methods: 405 Cone Beam CT scans provided by the "Digitom" Imaging Center in the city of Guayaquil were evaluated, of which 71 met the inclusion criteria. Results: The mean obtained for the classification (H) was 2.29mm (small) in 21.12% of the 71 patients. In the classification (V) the mean obtained was 5.1mm (medium) in 18.30% of the sample and the classification (C) in 60.56% of the patients, its mean was 5.4mm (medium) horizontally and 5.32mm (medium) vertically. Conclusion: The most prevalent crestal ridge bone defect was the combined defect (C) also being predominant the medium group (m) in an interval of 4 - 6 mm of crestal ridge resorption.
