PEEK Médica y Dental

Plástico PEEK de altas prestaciones desarrollado para aplicaciones de tecnología médica y dental. Este material puede estar hasta 30 días en contacto con sangre y tejidos y ofrece conformidad con la USP Class VI en la materia prima. Se realizan otras pruebas lote a lote según la norma ISO 10993-5 en el semielaborado. Igual que otras modalidades de PEEK, este PEEK white de grado médico demuestra una gran resistencia a la hidrólisis incluso a altas temperaturas, muy buena tolerancia a la esterilización y una extraordinaria resistencia química. En algunos casos, para determinadas aplicaciones dentales se puede aprobar un contacto prolongado de hasta 180 días.

BIOMATERIAL PROPERTY

1. Less inflammation

Biological complications including peri-implant disease avoided in most patient cases with PEEK prostheses.

2. High implant survival

Clinical studies demonstrate a high rate of implant survival in patients with a full-arch implant-supported fixed hybrid PEEK prosthethic.

3. Reduced bone loss

Up to 3x-lower marginal bone loss compared to metal framework implants.
