Young’s Modolus

Young’s modulus measures the ability of a material to stand up to changes in length when under lengthwise compression or tension. It’s also called the modulus of elasticity. Learning how to calculate the stiffness of a solid material is relatively straightforward in this case — Young’s modulus is equal to the longitudinal stress divided by the strain. Diamond has the highest Young’s modulus, and rubber has the lowest. Mild steel would be somewhere in between. Using a calculator to determine the Young’s modulus of different materials is important to implant dentistry for a variety of reasons. A periodontist must understand the Young’s modulus of the patient’s bone in the area the implant will be placed as well as the modulus and dimension of the implant itself. If there is a mismatch between the Young’s modulus of the bone and the implant, it could result in implant failure.
