SURFACE MECHANICAL PROPERTIES OF RESTORATIVE DENTAL MATERIALS

Dental materials are continuously renews itself with the development of science and technology and depending on uses and manufacturers, same materials can have some differences. dental materials must have certain mechanic properties. for example some restorative materials should not break under the biting force and must maintain their shape under load. the wear and discoloration over time should remain at minimum level, only in this way it is possible the restoration can be used for many years. abrasion, as a result of various external factors such as brushing in restorative materials is associated with hardness. this article compiles a review on these important surface mechanical properties of restorative dental materials and the methods of to determine these properties.
