Análisis de calidad del hueso maxilar superior según la escala de Hounsfield, UCSG semestre A-2018.

Abstract

The density of the maxillary bone, sex and age play an important role in bone quality and should always be taken into account when performing optimal treatment. Objective: To analyze the density of the maxillary bone with Hounsfield units to classify their quality and degree of edentulous bone resorption and to identify the prevalence of bone type in men and women of different ages. Methods and Materials: This investigation is a descriptive correlational analysis of the maxilla. 84 digital images of both sexes were divided into age groups: (18-34), (35-50) and (51+). The Dental-Viewer Invivo software was used to analyze the tomographies. The maxilla was divided into three sectors: anterior (canine), medium (premolars) and posterior (molars). The type of bone and the degree of resorption were analyzed according to the classifications of Misch and Lekholm and Zarb. Results: The densities varied from 165.7 HU to 1215.05 HU. The previous sector had the highest density, the middle sector was a mixture of D2, D3 and D4. Later sector consisted of type D3 (82%) and D41 (8%). Bone type D3 was more prevalent in both sexes. 65% of the patients suffered bone deficiency, classification A being the most prevalent. Discussion: The analysis that was carried out confirmed results similar to other studies on quality. However, there was a prevalence of bone D3. The degree of resorption was more drastic in patients of group 1 and 3.
