FARKLI KAYNAKLARDAN ÜRETİLMİŞ HİDROKSİAPATİTİN KEMİK ÇİMETOSU DAYANIMINA ETKİSİ

Öz

   Bu çalışmada, iki farklı kalsiyum kaynağı kullanılarak üretilen hidroksiapatit katkısı eklenerek yüksek mukavemetli akrilik kemik yapıştırıcısı üretilmiştir. Üretilen örnekler, XRD ve FT-IR kullanılarak karakterize edilmiştir. Termal davranışlar ve yüzey morfolojileri DTA/TG ve SEM teknikleri kullanılarak belirlenmiştir. Ca(OH)₂ ve deniz kabuğundan üretilen hidroksiapatit ilavesi, ortaya çıkan yapıştırıcıların basınç dayanımını (74 MPa'dan 106 MPa ve 103 MPa'ya) arttırmıştır. Bu yeni kemik yapıştırıcıları, ticari olarak temin edilebilen örneklerle karşılaştırılabilecek mekanik dayanımlara sahiptir ve hidroksiapatitin kemik yapısında mevcut doğal bir mineral olduğu için daha biyolojik olarak uyumlu olduğuna inanılmaktadır.

THE EFFECT OF HYDROXYAPATITE ADDITIVE PRODUCED FROM DIFFERENT RAW MATERIALS TO STRENGTH OF BONE CEMENT

Abstract

   In this study, production of acrylic bone cement which has high strength by adding hydroxyapatite additive that was produced using two different calcium sources was aimed. Characterizations were performed using XRD, and FT-IR. Thermal behaviors and surface morphologies were determined using DTA/TG and SEM techniques. The addition of hydroxyapatite produced from Ca(OH)₂ and seashell increased the compressive strength (from 74 MPa to 106 MPa and 103 MPa) of the resultant cements respectively. These new bone cements have mechanical strengths comparable with commercially available cements and are believed to be more biocompatible since hydroxyapatite is a natural mineral present in the bone structure.
