An evaluation of the effects of PDMS-based PDL on a Ti dental implant using FEM
| Resumo: | PDMS is a polymer with hyperelastic characteristics that have different qualities and numerous applications. Its use in the industry gradually increases every year, some sectors that can be cited as the most important are automotive, aeronautics, and biomechanics. Because it is colorless, inert, odorless, biocompatible, and with mechanical properties to some tissues of the human body, its use in biomechanics, more specifically in odontology, is inherent. The vast majority of dental implants are made of titanium, a material that despite being biocompatible, has mechanical properties incredibly superior to cortical bone, medullary, and even natural teeth. This makes it difficult for the implant to do its job properly, as it would absorb minimal amounts of energy. Thus putting great stress on the jawbones, can cause discomfort, rejection, premature failure, among others. After the removal of a natural tooth, the periodontal ligament (PDL), which is a soft film around the tooth root, is lost. It has fundamental functions, as it is elastic, partially absorbs the mechanical energy deposited on the tooth crest, increases the area of contact with the bone, and protects it. Therefore, the objective of this work is to numerically simulate a PDMS film replacing the lost PDL. The present work studied a PDMS film as a substitute form of PDL. The data referring to the PDMS were taken from tensile tests and other materials by the theoretical framework. The simulations performed by FEM create hypothetical situations that the implant with and without film would face to study its behavior. Therefore, this project verified that the PDMS reduced the stresses in the implant, for the abutment had a momentary increase in stress even when there is contact with the crown, then it reduces the stress growth rate, both expected behaviors. It acted similarly to the periodontal ligament in terms of tension distribution in the bone, it was observed that even maintaining maximum stress, it is more dispersed and relocated to the fundus, instead of the crest. The results of this project are only linked to the studied geometry, another implant would probably present other results. Therefore, it is not possible to state that PDMS is a definitive replacement for PDL, but indicates that it is a candidate. |
