What is ISO 4049 - Polymer-based restorative materials about?
ISO 4049 is an international standard that focuses on dentistry polymer-based restorative materials. ISO 4049 specifies requirements for dental polymer-based restorative materials supplied in a form suitable for mechanical mixing, hand-mixing, or intra-oral and extra-oral external energy activation, and intended for use primarily for the direct or indirect restoration of the teeth and luting.
The polymer-based luting materials covered by ISO 4049 are intended for use in the cementation or fixation of restorations and appliances such as inlays, inlays, veneers, crowns, and bridges.
Note-
ISO 4049 does not cover polymer-based materials intended to prevent caries, core materials or those used for veneering metal sub-frames
Who is ISO 4049- Polymer-based restorative materials for?
ISO 4049 on dentistry polymer-based restorative material is useful for:
- Dentists
- Hospitals
- Production unit of polymer-based restorative material
Why should you use ISO 4049- Polymer-based restorative materials?
Polymers have a major role in most areas of restorative dentistry. The most widely used impression materials are elastomeric polymers. Another major type of polymeric dental material is the composite filling material for anterior teeth. Removable dentures are made from acrylic resin and other polymers.
The objective of ISO 4049 is to review the kinds of literature on the latest advancements in the use of medicine and dentistry.
ISO 4049 also provides basic information regarding teeth, composition, decay, curing decayed teeth with different filling materials. The composition and types of various dental fillings are also included.
ISO 4049 guides you with requirements for dental polymer-based restorative materials used primarily for the direct or indirect restoration of the teeth and luting.
What’s changed since the last update?
BS EN ISO 4049:2019 supersedes BS EN ISO 4049:2009. BS EN ISO 4049:2019 includes some technical changes with respect to BS EN ISO 4049:2009. These include:
- The test for sensitivity to ambient light has been changed because a filter used in the current test was not available
- The test for radio-opacity has been updated to refer to iso 13116
- Luting materials no longer must conform to the requirement for depth of cure
- The manufacturer is now required to publish details of material composition
- Several minor changes have been made to clarify content together with editorial changes
