Abstract

   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.
