“…In clinical situations, it is extremely difficult to calculate stresses generated within and around the restorative material. Therefore, stress analysis using FEA is often regarded as an ideal approach to evaluate stresses in the restorations under simulated clinical conditions [15,31]. The stress between the restorative material and the tooth structure was also analysed using FEA in this study.…”

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.

“…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].…”

“…The finite element method (FEM) solution does not have the restrictions of laboratory testing and it can be used to study the effects of various parameters on heat distribution and for the thermal analysis of dental implants. This method has been used to analyze the mechanical stress and thermal‐mechanical stress in dental implants as well as temperature distribution and thermal stress in the intact tooth …”

“…Disregarding the immediately-or delayed-loading types, dislocation of the implant may lead to failure to the replacement procedure and imposes clinical and financial costs to the patients. The stability of a dental implant closely relies on either the endogenic (like bone quality, vasculature, infective or inflammatory diseases, etc) or the exogenic (loading type, implant design, life style, etc) conditions [4][5][6][7][8][9][10]. Low bone quality is a most relevant reason that challenges the implantation success [11], and can reduce the implant stability due to the overall osteoporosis specifically for the aged patients or local lack of osteogenic cells at the boneimplant interface (BII) [12,13].…”

Background: Consumption of hot substances may harm the surrounding bone around a dental implant. High temperatures at the bone-implant interface (BII) interferes with local cellular activities involved in the osteointegration. Objectives: The present study was aimed at calculating the temperature distribution through the BII and the jaw bone under application of a transient cyclic thermal load. Methods: In this numerical simulation, finite element method was employed in a commercialized dental implant model drawn by computer-aided design tools based on CT data to find the temperature in superficial and deep bone regions near the BII. The heat load was applied cyclically during the intake time. Results: Results showed that the highest temperature was occurred at the top regions of the interface by magnitude of 48 C. Removal of the thermal loads also was followed by rapid decrease in the bone temperature. Conclusions: Routine beverages of a hot liquid can increase the temperature of the bone beyond the biological thresholds of the bone cells vitality or remodeling functionality, specifically in the delayed loading types of implantation.
