Development of calcium silicate/calcium phosphate cement for bone regeneration

Biomedical Materials, 2007
A new type of composite bone cement was prepared and investigated by adding calcium silicate (CS) to calcium phosphate cement (CPC). Low-crystalline CS prepared by heat treatment at low temperature had excellent bioactivity and degradability. Adding CS to CPC did not affect the phase composition and chemical structure of CPC, and had a little effect on

A hybrid zinc–calcium–silicate polyalkenoate bone cement

Biomaterials, 2003
A novel bone cement composed of sintered zinc-calcium-silicate phosphate and hybrid polyalkenoates has been developed. Synthesis and formulation of glass fillers, monomers and polymers as well as formulation of the cement were described. The effects of sintering, polymer content, glass powder/polymer liquid (P/L) ratio and comonomer on compressive ...

Vinylphosphonic acid-modified calcium aluminate and calcium silicate cements

Journal of Materials Science, 1996
Cementitious materials in terms of calcium phosphate cements (CPC) were prepared through the acid-base reaction between vinylphosphonic acid (VPA) and calcium aluminate cement (CAC) reactants or calcium silicate cement (CSC) reactants at 25 °C. Using CAC, two factors were responsible for the development of strength in the cements: one is the formation ...

Novel calcium phosphate coated calcium silicate-based cement: in vitro evaluation

Biomedical Materials, 2020
Calcium silicate-based cements are known for their wide applications in dentistry and orthopedics. The alkaline pH (up to 12) of these cements limits their application in other orthopedic areas. In this study, the effect of dicalcium phosphate dihydrate (DCPD) coating on set cement on pH reduction and biocompatibility improvement was examined.

In vivo biocompatibility and biomineralization of calcium silicate cements

European Journal of Oral Sciences, 2018
A new mineral trioxide aggregate (MTA) material has been developed with a modified composition that requires investigations to support its clinical use. This study evaluated the biocompatibility and biomineralization of this new MTA material and compared it with that of two other MTA cements over time.

Calcium silicate‐based cements: composition, properties, and clinical applications

Journal of Investigative and Clinical Dentistry, 2015
AbstractMineral trioxide aggregate (MTA) is a calcium silicate‐based cement (CSC) commonly used in endodontic procedures involving pulpal regeneration and hard tissue repair, such as pulp capping, pulpotomy, apexogenesis, apexification, perforation repair, and root‐end filling.

Physicochemical Properties of Calcium Silicate Cements for Endodontic Treatment

Journal of Endodontics, 2009
The purpose of this study was to examine the physicochemical properties of novel calcium silicate cements (CSCs) prepared by using a sol-gel method.The compressive strength, morphology, and phase composition of various cements were evaluated after mixing with water, in addition to setting time and pH value.As solid phases, the sol-gel-derived powders ...

Conventional Portland Cement and Carbonated Calcium Silicate–Based Cement Systems

Transportation Research Record: Journal of the Transportation Research Board, 2015
The behavior of two cementitious materials during thermal changes associated with freezing and thawing in presence of calcium chloride deicing salts was examined. The two systems consisted of a conventional portland cement-based material and an alternative economically friendly cement that formed a solid by carbonating a calcium silicate–based cement.

Physicochemical properties of calcium silicate cement based endodontic sealers

Journal of the Mechanical Behavior of Biomedical Materials
To mensure the physicochemical properties of three ceramic cement endodontic sealers AH Plus Bioceramic, Bio-C Sealer and Bio-C Sealer Ion+ with an epoxy resin sealer, AH Plus.These properties were measured: hardening time (HT), dimensional change (DC), solubility (SL), flow (FL) and radiopacity (RD).
