Improvement of mechanical, thermal and biological properties of acrylic-based bone cements by adding various chemicals is a novel research area. Among these additives, hydroxyapatite (HA) is proven to be a biocompatible and osteoconductive material and it strongly integrates with bone. In this study, HA-containing acrylic bone cements were prepared and thermal and mechanical properties of the resultant cements were examined.

Preparation, modification, and characterization of acrylic cements Basgorenay, B; Ulubayram, K; Serbetci, K; Onurhan, E; Hasırcı, Nesrin (2006-03-15) Acrylic cements with different compositions were prepared by mixing the solid part (composed of poly(methyl methacrylate), PMMA, and benzoyl peroxide, BPO) and the liquid part (composed of methyl methacrylate, MMA, and N,N-dimethyl-p-toluidine, DMPT), modified by addition of hydroxyapatite (HA) and ammonium nitrate (AN) and characterized by measuring thermal and mechanical properties. Three sets of samples were prepared. For B-group, the total amount of solid including HA was constant but the PMMA to HA rat...
Thermal and mechanical properties of microwave- and heat-cured poly(methyl methacrylate) used as dental base material Usanmaz, Ali; Ates, J; Dogan, A (Wiley, 2003-10-03) The thermal and mechanical properties of dental base materials cured by microwave and conventional heat methods were studied. The commercial dental base poly(methvl metacrylate) (PMMA) powder and liquid were mixed in a 3/1 ratio. They were polymerized by a peroxy catalyst at 63degreesC, then cured with a boiling water temperature and microwave radiation for periods of 5, 10, 15, 20, 25, 30, and 35 min for heat curing and 1, 2, 3, 5, and 7 min for microwave radiation. The microwave radiation outputs used wer...
Modification of Acrylic Bone Cements with Oxygen Plasma and Additives Endoğan Tanır, Tuğba; Kızıltay, Aysel; Hasırcı, Vasıf Nejat; Hasırcı, Nesrin (2012-09-01) Acrylic bone cements which are commonly used for the fixation of orthopedic prostheses, were prepared at different formulations, by using either ground poly(methyl methacrylate) (PMMA) particles or homogeneously synthesized PMMA microspheres with application of plasma and addition of various ingredients in order to improve mechanical and thermal properties. PMMA powders having three different particle size (ground and sieved particles with 0-50 mu m (BC1 group, average particle size: 21 mu m) and 50-150 mu ...
Effects of Ingredients on Thermal and Mechanical Properties of Acrylic Bone Cements Endoğan Tanır, Tuğba; Hasırcı, Nesrin (2009-09-15) There is a very delicate relation between the amounts of all the ingredients present in the cement composition and the properties of the product. In this study, homogeneous poly(methyl methacrylate) (PMMA) microspheres were prepared by suspension polymerization technique, and used in cement formulations. Various acrylic cements with different compositions were prepared by using PMMA microspheres, methyl methacrylate (MMA) monomer, radiopaque agent of barium sulfate (BaSO4), inorganic particles of hydroxyapa...
Thermal degradation of poly(propylene oxide) and polyepichlorohydrin by direct pyrolysis mass spectrometry Uyar, T; Hacaloğlu, Jale (2002-09-01) The thermal degradation of poly(propylene oxide), (PPO) and polyepichlorohydrin, (PECH) were studied with the use of direct pyrolysis mass spectrometry. The effects of heating rate and dissociative ionization on fragmentation pattern have also been investigated. It has been determined that PPO degrades via a random cleavage mechanism, the labile C-O bond scissions being preferred, An analogous degradation mechanism can be proposed for PECH. Yet, the elimination of side chains, evolution of HCl and the loss ...
