ISO 27020 discusses brackets and tubes for use in orthodontics for dentistry. ISO 27020 outlines the requirements and test methods to compare the functional dimensions of orthodontic brackets and tubes and their chemical ion release, as well as packaging and labelling information.
ISO 27020 is applicable to brackets and tubes for use in fixed orthodontic appliances.
Note: ISO 27020 does not specify specific qualitative and quantitative requirements for freedom from biological hazards which are covered in ISO 10993-1 and ISO 7405.
ISO 27020 on brackets and tubes for use in orthodontics is useful for:
Brackets are small metal squares that are attached to the front and side teeth. They act like handles that allow us to grab onto the teeth to move them. They are bonded directly to the enamel of the tooth with a special adhesive. Tubes (stainless steel that allows wires to pass through them) are typically welded to bands but they may also be glued directly to molars.
ISO 27020 best practice guideline provides requirements on hazardous elements, release, dimensions, and angles for brackets and tubes for use in orthodontics. ISO 27020 provides test methods on dimensions, static immersion corrosion test method, and treatment of results for brackets and tubes for use in orthodontics. ISO 27020 also provides packaging, labelling, and information to be provided to the user.
This helps in improving the quality of brackets and tubes for use in orthodontics and ensures the patient’s health and safety.
BS EN ISO 27020:2019 supersedes ISO 27020:2019, which has been withdrawn. BS EN ISO 27020:2019 has the inclusion of a new corrosion test with respect to ISO 27020:2019.
