POLİETER ETER KETON (PEEK) ve DENTAL KULLANIMI

Abstract

Polyether Ether Ketone (PEEK), is a semi-crystalline high-temperature thermoplastic polymer in polyaryl ether ketone family. PEEK of high mechanic and physical features, thermal and dimensional stability, is one of rare polymers seen as an alternative to metal materials in many industrial fields. With its features like, high-corrosion and chemical resistance and compatible biomechanic features, long-life and biocompatibility, PEEK began to be used especially in medicine as high-performance thermoplastic material alternative to metal-composite implants in orthopedics in the late 1990's. PEEK is used as an implant material, because of its elasticity module. That's why it is used as a prosthetic material in dentistry. In this study, the structure, general features and the use of PEEK material are explained.

Protetik Diş Hekimliğinde Polietereterketon Materyalinin Yeri

“…Ağız içindeki kimyasal ortamdan etkilenmeyen PEEK materyalinde çözünmeye sebep olduğu bilinen tek kimyasal oda sıcaklığında %98'lik sülfürik asittir. 5 PEEK'in kimyasal ve ısısal kararlılığı sayesinde buhar, gama ve etilen oksit sterilizasyonları, materyalin fiziksel özelliklerinde değişime yol açmamaktadır. 6 PEEK biyouyumlu bir materyaldir.…”
