Question

write why following properties needs to be considered while making molar teeth: bodily response, youngs modulus, fracture toughness, yield strength, density, and thermal conductivity. write one, two sentences for each of these properties important for molar teeth. please also tell whether material with high density, thermal conductivity is good for molar teeth. or not? why?

Answer 1

Bodily response:
Allergy reaction can occur with the material due to hypersensitivity it cause implant-related allergic reaction. The material should be selected very careful for dental replication to regenerate issues and tissue function to interact with the biological system.
Young's module:
It is known as an elastic module, it is used to measure rigidity of material and ratio of stress and strain, that ability of enamel and dentin to resist elastic deformation so that Young's modulus to be considered.
Fracture toughness:
Fracture toughness reduces significant standard metal dies to produce better reproductivity and comparability. Monolithic crowns have more fracture load values for the aging simulation design.
Yield strength:
Application of resin monomers to precondition, stress at which material strength with plastic strain important.
Density:
adequate bone level and density important for supporting the implant.
thermal conductivity:
It is to be considered to prevent damage, disease or fractured teeth.
High density leads to crack growth and high thermal conductivity leads to an increase in marginal leakage in composite restorations with high viscosity and lower water sorptions values. a thermal character affected by composition, powder-liquid ratio and water sorption. high thermal properties lead to high powder liquid ration.
