Análise de diferentes métodos de determinação do biótipo periodontal

Abstract

The aim of this study was to determine, by analyzing different methods of determination, the periodontal biotype of teeth and prosthetic spaces in patients prior to the unitary rehabilitation with dental implants, including anterior and posterior regions. and immediate loading in aesthetic areas. This is a diagnostic study through evaluation of periodontal patients before treatment unit prosthetic dental implants. An initial sample of 34 patients was considered. The study included patients with unit absences in cosmetic area and periodontal health. They excluded patients with multiple absences candidates for rehabilitation with unitary prosthesis in no aesthetic region not exposed to smile. The probing depth, transparency on probing, the presence of recession, the sizes of crowns and buds adjacent to the prosthetic space, the horizontal gingival thickness and the horizontal and vertical thickness of keratinized tissue were evaluated parameters. Significant correlations were found between horizontal mucosa thickness for the prosthetic vertical space and mucosal thickness of the prosthetic area (p <0.001) and the horizontal thickness of the mucosa adjacent to the prosthetic teeth horizontal space and thick space for the prosthetic (p = 0.001). There were no correlations between the horizontal / vertical thickness and other variables of interest: the transparency survey, gender, height and width of the crowns and buds, depth vestibular probing and right height / width of crowns and buds. The cluster analysis (clusters) cluster resulted in two well defined groups, G1 (thick biotype) and G2 (thin biotype) which, when analyzed for the above variables, showed significant differences for transparency survey (p = 0.04) vertical thickness of the prosthetic area (p <0.001), horizontal thickness of the adjacent teeth (p <0.001), buccal probing depth (p = 0.05) and ratio height / width of the papillae of adjacent teeth (p = 0.02 ). The poll transparency test achieved 77.8% sensitivity and 56.3% specificity with overall accuracy of 67.7%. Periodontal biotypes are classifiable, have different morphometric parameters and have as key influencers horizontal gingival thickness, vertical gingival thickness and transparency vestibular probing for classification. The method of transparency on probing was effective in diagnosing types evaluated periodontal biotypes.
