Canadian Health and Care: Dental treatment
Endodontically-treated teeth have greater risk of biomechanical complications compared to vital teeth. The loss of structural integrity caused by trauma, caries, access hole preparations, loss of moisture content, and reduced thickness of dentine lead to decreased fracture resistance of such teeth. Endodontic post and core systems have been commonly used to restore the missing part of the tooth structure to prevent fracture of the residual tooth and to improve retention of the final restoration. Since cast metal or prefabricated posts materials affect the amplitude and distribution of stresses in root […]
