In Vitro Study Regarding the Biomechanical Behaviour of Bone and Periodontal Splints I.Model validation

Abstract

This paper is part of a larger study that aims to evaluate the biomechanical behaviour of mandibular bone and periodontal splinting systems subjected to different occlusal forces by means of electric resistive tensometry (ERT). The research was based on the following premise: the degree of bone resorption and periodontal type of splint influence the deformation of the mandibular bone. The study was conducted in two stages: first, the validation of the mandibular dental arch model, which is the subject of the present article, and second, the evaluation of mandibular bone strain in case of different types of bone loss and periodontal splints, which is the subject of a second article.

Evaluation and Prevention of Changes in Oral Cavity Through Cytotoxic Effect of the Chemical Components from Dental Materials

“…concerning tisular reactions [12]. These aspects were also demonstrated in others studies [13][14][15][16][17][18][19][20][21][22]. It is difficult to explain, at this moment, the difference noticed between the two mentioned aspects, it being probably related to the different sensitivity of the two methods of investigation, biochemical and flowcitometric.…”

“…Batch: 2373741). The fabrication and validation of the models were previously described in detail [34]. In brief, each model comprised of eight extracted mandibular teeth, from the first right premolar, to the first left premolar.…”

“…The purpose of the study was to evaluate the biomechanical behaviour of mandibular bone by means of electric resistive tensometry method, in case of different periodontal splinting systems subjected to different occlusal forces. The method was described in the first part of this research, in a previous paper [34]. The premise of this research wa that the degree of the bone resorption and the type of the periodontal splint influence the tooth displacements and, consequently, the deformation of the mandibular bone, resulted in the recorded strain values.…”

“…RP = right premolar; RC = right canine; RLI = right lateral incisor; RCI = right central incisor; LCI = left central incisor; LLI = left lateral incisor; LC = left canine; LP = left premolar; BR = bone resorption, WRC= wire-composite splint;FRC = fiber-reinforced composite splint[34].…”
