Abstract:	The study seeks to highlight the correlation between the different geometric shape of the marginal cervical limit of the prepared teeth for prosthetic restorations, together with the distribution, the value of tensions and deformations that occur in the tooth during occlusal stress. In order to achieve our goal, we used finite element methods, which assured us to obtain data for the optimal form of the dental preparations, generating a favorable prognosis for the prosthetic treatment, along with the established therapeutic methods in order to increase therapeutic and prophylactic efficiency for the fixed dentures. From this point of view the round edges of the fixed prosthetic limits are the most favorable.
Keywords:	stress, form, marginal, threshold, limits.
