ISO 4823 addresses elastomeric impression and bite registration materials for dentistry purposes and specifies the requirements and their test methods for elastomeric impression and bite registration materials.
Treatments, such as removable and fixed prostheses, can be executed thanks to dental casts. The final restoration and prosthesis fit depends on how accurately the impression material has recorded the tissue details.
Note: ISO 4823 does not address possible biological hazards associated with the materials. Assessment of these hazards is addressed in ISO 7405 and the ISO 10993 series.
ISO 4823 on elastomeric impression and bite registration materials is useful for:
Impression materials are used to copy the teeth and surrounding structures by creating a dental impression poured with dental plaster to fabricate dental cast.
This procedure provides a tridimensional and accurate mouth replica, allowing dental work in the absence of the patient.
ISO 4823 helps you with requirements and their test methods for the manufacturing process of elastomeric impression and bite registration materials which ensure patients’ health and safety and help dentists to perform a better diagnosis and treatment planning.
