TPE for Dental Bracket Covers
For a Comfortable Fit
Orthodontic braces not only contribute to creating an attractive smile but also improve the dental health of those who undergo treatment. Occasionally, patients can feel discomfort caused by friction from the wires or brackets against the mouth. To avoid discomfort during treatment, manufacturers in the medical/dental field have created dental bracket covers using a Thermoplast M compound from Kraiburg TPE, Waldkraiburg, Germany.
As the dental bracket cover is placedin the mouth to conceal both the front and the back of the teeth, the application uses a Thermoplast M material certified according to DIN ISO 10993-5 (cytotoxicity), ISO 10993-10 (intracutaneous irritation), ISO 10993-4 (Hemolysis) and ISO 10993-11 (acute system toxicity). This material is safe to use in direct body contact applications such as the one described. The compound combines an 89 shore A hardness as well as good mechanical, flow properties and transparency. The TPE has the added advantage that it can be processed by extrusion or injection molding methods. The material will also adhere to polypropylene with a two-shot or insert molded process. Lastly, this compound is sterilizable for multiple usage.
