“…The performance of most ductile materials such as restorative materials can be predicted using von Misses stress. In addition, this stress has to be considered when evaluating the appropriate dental material to use, as well as the hard tissue damage that may happen [14]. Due to this, it is possible to detect whether or not it is likely for permanent deformation or breakage to occur in the material [15].…”

Glass carbomer cement is a new dental material developed from the traditional glass ionomer cements. It has better mechanical and chemical features when compared to the conventional glass ionomer cements. The purpose of this in silico investigation was to examine the influence of glass carbomer and composite resin materials with class I cavity design on stresses happening in the inlay. Finite-element analysis and three-dimensional modelling were used to examine the stress in the glass carbomer and hybrid composite inlays resulting from a 300-N point load on occlusal surfaces. Two different inlay materials, glass carbomer cement and hybrid composite resin, were evaluated. The maximum von Misses stress values in the composite resin inlays were significantly lower than those in the glass carbomer inlays. The results from this study showed that the resistance of the glass carbomer against the forces was higher than that of the composite resin inlays. The stresses were concentrated mostly at similar regions. The obtained results suggest that glass carbomer may be recommended as a preferred filler restorative material in teeth with much structure loss.

“…Guven et al 22 have analyzed the influence of inlay cavity design by FEA and reported that cavities with rounded corners showed less stress than those with rectangular corners due to improved stress distribution capabilities of rounded corners. The model of conventional inlay has a box-shaped cavity with sharp margins.…”

“…[15][16][17][18] Modern computer aided design and finite element analysis (CAD-FEA) methodologies play an essential role in biomedical investigations of clinical situations in various dental fields. [19][20][21][22][23][24][25][26] When practiced in living subjects, some dental research studies are expensive and ethically doubtful. Conversely, using virtual models and simulations can improve investigation performance, reduce the cost of in vitro and in vivo experiments, and improve profitability.…”

This study aimed to analyze stress distribution and maximum von Mises stress generated in intracoronal restorations and in tooth structures of mandibular molars with various types of cavity designs and materials. Materials and Methods: Threedimensional solid models of mandible molar such as O inlay cavity with composite and gold (OR-C, OG-C), MO inlay cavity with composite and gold (MR-C, MG-C), and minimal invasive cavity on occlusal and proximal surfaces (OR-M, MR-M) were designed. To simulate masticatory force, static axial load with total force of 200 N was applied on the tooth at 10 occlusal contact points. A finite element analysis was performed to predict stress distribution generated by occlusal loading. Results: Restorations with minimal cavity design generated significantly lower values of von Mises stress (OR-M model: 26.8 MPa; MR-M model: 72.7 MPa) compared to those with conventional cavity design (341.9 MPa to 397.2 MPa). In tooth structure, magnitudes of maximum von Mises stresses were similar among models with conventional design (372.8-412.9 MPa) and models with minimal cavity design (361.1-384.4 MPa). Conclusion: Minimal invasive models generated smaller maximum von Mises stresses within restorations. Within the enamel, similar maximum von Mises stresses were observed for models with minimal cavity design and those with conventional design.

Aim: The aim of this study was to compare the stress distribution under artificial forces that simulate the biting forces of the two different post types used in maxillary anterior teeth that had complicated crownroot fractures and to determine the region where the stress occurred. For this purpose, a finite element analysis method was used. Material and method: In the study, Glass fiber post (Group I) and carbon fiber post (Group II) were used to model tooth with complicated crown-root fracture, which would be horizontal in the cervical region of the fracture line. In the model, fractured teeth fragment (coronal and root fragments) were reattachment to by post. The force of 100N was applied to the incisal of the teeth at 90 0 angles to the groups (longitudinal axis). Finite element analysis method was used to evaluate stress resulting from force and to obtain a three-dimensional model. Analyzes were done with the ANSYS program (ANSYSRel.6.0, ANSYS Inc., Houston, TX, USA). Results: As the results of the analysis, the resistance of glass fiber post against the forces was higher than the carbon fiber post. The stresses were concentrated mostly at the palatinal regions in group I and II. Conclusion: The rehabilitation of esthetic and functional for anterior group teeth with complicated crown-root fractures was favorable glass fiber post than carbon fiber post.
