Tests of all ceramic materials for eithe
31、r metal or ceramic substructures are now contained in a global ceramics standard ISO 6872. Some elements of ISO 9693:1999 remain for all materials (e.g. measurement of thermal expansion coefficients) and one remains only for porcelain fired to zirconia (Schwickerath bond characterization test). New
32、requirements have been added for porcelain-ceramic systems, including thermal shock testing for ceramic-ceramic compatibility (allowing many protocols that are in widespread use within industry).ISO 9693 consists of the following parts, under the general title Dentistry Compatibility testing: Part 1

Their compatibility under mechanical and thermal loading is essent
34、ial if they are to function in a prosthetic construction. This part of ISO 9693 sets out requirements and test methods for allowing the risks associated with masticatory forces and the oral environment to be assessed.Specific qualitative and quantitative requirements for freedom from biological haza
35、rds are not included in this International Standard, but, in assessing possible biological hazards, reference can be made to ISO 10993-1 and ISO 7405.DIN EN ISO 9693-2:2016-07 EN ISO 9693-2:2016 (E) 5 1 ScopeThis part of ISO 9693 specifies requirements and test methods to assess the compatibility of
36、 ceramic-ceramic materials used for dental restorations by testing composite structures.The requirements of this part of ISO 9693 apply when different ceramic components are used in combination. Compliance cannot be claimed for either ceramic alone.For requirements of ceramic materials, see ISO 6872

Test in accordance with 6.3.4.2.4 Thermal shock resistanceAt least one test for resistance to thermal shock shall be performed according to 6.4.2 or 6.4.3.Note The measured values for coefficients
44、 of linear thermal expansion are compared with the manufacturers values as a means of quality control, but the values cannot provide an assurance that the ceramic substructure and ceramic veneer are compatible.5 Sampling5.1 Substructure dental ceramicThe sample shall be adequate to prepare the speci
