Dental materials. Guidance on testing of wear - Wear by toothbrushing1 Scope This part of ISO TR 14569 provides guidelines for test methods for the assessment of resistance to wear by tooth brushing for the following materials: materials used for the preparation of artificial teeth; veneering of crowns and bridges. This part of ISO TR 14569 does not cover phenomena such as the marginal degradation and loss of substance by chemical processes, swelling, splintering of edges or wear from contact with the antagonist.
