Introduction: In 2001, Cavex presented the first test results, which showed 5 days dimensional stability for Cavex ColorChange. More than 10 years we used this information to show our customers the high quality and stability of our products. In the meantime, our Research & Development department worked on improvements of the alginate impression materials. We formed close cooperation’s with supp...

Alginic acid gels were studied by small-angle X-ray scattering and rheology to elucidate the influence of alginate chemical composition and molecular weight on the gel elasticity and molecular structure. The alginic acid gels were prepared by homogeneous pH reduction throughout the sample. Three alginates with different chemical composition and sequence, and two to three different molecular wei...

Irreversible hydrocolloids, or simply alginates, are the most used molding materials in different areas of dentistry, due to their ease handling, low cost and good reproducibility. The present work aims analyze dimensional stability types alginates at time intervals. It is applied research, which its approach was qualitative-quantitative, an exploratory nature. Three brands alginate were used, ...

This review article presents the recent advances in syntheses and applications of nanocomposites consisting of graphene derivatives with various polysaccharides. Graphene has recently attracted much interest in the materials field due to its unique 2D structure and outstanding properties. To follow, the physical and mechanical properties of graphene are then introduced. However it was observed ...

introduction: complete adhesion of the impression materials to trays is important to prevent impression materials from being pulled away from trays during removed from the mouth and to ensure that the direction of polymerization shrinkage will be towards the tray. the aim of this study was to evaluate the effects of two retention features of custom trays (adhesive vs holes) on the dimensional a...

Corn starch gels (1:4 w:w) were made with the addition (up to 2% w/w basis) of sodium alginates different average molecular sizes and nature. Rheology starchy characterized evaluate their viscoelasticity. Gels subjected in vitro digestion estimate effect on glycemic response. Tested significantly decreased value elastic modulus gels. The coordination number obtained from complex indicated that ...

Alginates are natural anionic polyelectrolytes investigated in various biomedical applications, such as drug delivery, tissue engineering, and 3D bioprinting. Functionalization of alginates is one possible way to provide a broad range requirements for those applications. A techniques, including esterification, amidation, acetylation, phosphorylation, sulfation, graft copolymerization, oxidation...
