Mechanobiological Analysis of Molar Teeth with Carious Lesions through the Finite Element Method

الملخص EN

The analysis of the distribution of stress in dental organs is a poorly studied area.

That is why computational mechanobiological analysis at the tissue level using the finite element method is very useful to achieve a better understanding of the biomechanics and the behaviour of dental tissues in various pathologies.

This knowledge will allow better diagnoses, customize treatment plans, and establish the basis for the development of better restoration materials.

In the present work, through the use of high-fidelity biomodels, computational mechanobiological analyses were performed on four molar models affected with four different degrees of caries, which are subjected to masticatory forces.

With the analyses performed, it is possible to observe that the masticatory forces that act on the enamel are not transmitted to the dentin and to the bone and periodontal ligament to protect the nerve, as it happens in a healthy dental organ.

With the presence of decay, these forces are transmitted partly to the pulp.

The reactions to the external loads on the dental organs depend on the advances of the carious lesion that they present, since the distribution of stresses is different in a healthy tooth.
