Introduction: The prosthetic rehabilitation of lost oral structures, aimed the recovery of function, aesthetics and morphology. Are described associations between morphology and oral health, therefore it is an important aspect of this study since the literature is not conclusive. Goals: Comparative analysis of vestibular contours of dental crowns and the respective alveolar processes. The relationships of dental contours with the subjective evaluations of the operator and patient and worsening of periodontal health. Materials and Methods: Proceeded to comparison of coronary contour line with the respective alveolar apophysis of 40 dental pieces from patients of the Clínica Universitária da Universidade Católica Portuguesa - Centro Regional das Beiras. The contour line coincides with the longitudinal axis of the dental structure through the zenith. There was data collection through alginate impressions and study models. There were performed profile photographs of the structures of interest, so that the incidence axis of the uptake was coincident with the zenith and perpendicular to the contour. In certain cases we used keys in addition silicone. The photographs were edited in CorelDRAW X5. For analysis and processing of data we used the statistical program SPSS (IBM Corp. IBM SPSS Statistics 2013 Released for Windows®, Version 22.0 Armonk, NY:. Corp. IBM) using Cramer's V and Mann-Whitney test. Results and Conclusion: There was a trend for the existence of symmetry between the curvature of the alveolar apophysis impression the curvature of the labial surface of the crown, observed in 74,3% of cases that need to be clarified in future studies. The curvature of the alveolar apophysis was more pronounced at 60,0% than the corresponding crown / tooth. Of the total sample, 74,3% of cases were identified as being the operator with the correct contour. When evaluated by the patients the percentage rise to 82,9%. The sample did not allow the proper clarification of the relationship between the symmetry, type of structure, operator impression, patient impression, contour and worsening of periodontal health. Of total rehabilitated cases, 81,3% had worsening of local periodontal health. In future studies, it would important control the variable adaptation from the gingival margin since in the most cases showed an incorrect marginal adaptation impression and absence of symmetry
