Dual-setting calcium phosphate cement modified with ammonium polyacrylate.
alpha-Tricalcium phosphate bone cement, as formerly designed and developed by Driessens et al., consists of a powder composed by alpha-tricalcium phosphate (alpha-TCP) and hydroxyapatite (HA) seeds, and an aqueous solution of Na2HPO4 as mixing liquid. After mixing powder and liquid, alpha-TCP dissolves into the liquid and calcium deficient hydroxyapatite (CDHA), more insoluble than the former, ...
متن کاملDevelopment of a dual-cure mineral trioxide aggregate-based cement: Biological, physical, and mechanical properties
Purpose The purpose of this study is to compare the physical, mechanical, and biocompatibility properties of a new dual-cure white mineral trioxide aggregate (D-W-MTA) and a commercial W-MTA. Materials and Methods Diametral tensile strength (DTS), water sorption (WSp), and water solubility (WSl) tests were performed. Cytotoxicity was observed in primary culture of human pulp fibroblasts (HPFs...
متن کاملDevelopment, characterization, and validation of porous carbonated hydroxyapatite bone cement.
Carbonated hydroxyapatite (CHA) bone cement is capable of self-setting and forming structures similar to mineralized bone. Conventional CHA leaves little room for new bone formation and delays remodeling. The purposes of this study were to develop porous CHA (PCHA) bone cement and to investigate its physicochemical properties, biocompatibility, biodegradation, and in vivo bone repair potential....
متن کاملExperimental facial augmentation with hydroxyapatite cement.
OBJECTIVE To study the results of implantation of preformed hydroxyapatite (HA) disks and HA cement in onlay augmentation. METHODS In this prospective study involving 16 adult New Zealand rabbits, HA disk and HA cement samples were implanted separately and together along the bony and cartilaginous nasal dorsum as well as over the supraorbital bone. Gross and histologic examinations of the imp...
متن کاملHydroxyapatite cement in craniofacial reconstruction.
OBJECTIVES To evaluate the long-term efficacy of hydroxyapatite cement in craniofacial reconstruction, specifically examining the role (if any) of radiation, implant location, and cement type. STUDY DESIGN A retrospective chart review was conducted of all patients presenting to the senior surgeon (Y.D.) for craniofacial reconstruction from September 1997 to April 2004. METHODS Data were col...
