Compatibility of alginate impression materials and dental stones

The Journal of Prosthetic Dentistry, 1971
Abstract Four alginate (irreversible hydrocolloid) impression materials certified as meeting A.D.A. specification 18 for hydrocolloid impression materials were tested for compatibility with five dental stones (20 tests). Five samples of each alginate-stone combination were made and evaluated (100 casts).

Thiokol as a dental impression material

Acta Odontologica Scandinavica, 1957
About two years ago a new type of elastic impression material, based on the synthetic rubber Thiokol, was placed on the market. The material is supplied in two tubes, the contents of which are mixed to a homogeneous paste before use. At or above room temperature the mix will quickly polymerize to form a rubbery mass.

Alginate dental impression materials: Chemistry, structure, and properties

Journal of Biomedical Materials Research, 1986
AbstractThe setting behavior of calcium alginate impression materials was investigated by monitoring the viscosity, calcium ion activity, and shear modulus during the reaction. Structural information was also obtained from the dependence of viscosity and compressive modulus on the calcium concentration in model systems.

Antimicrobial activities of dental impression materials.

Dental materials : official publication of the Academy of Dental Materials, 1999
The aim of this study was to measure the in vitro killing effects five commercial alginate impression materials had on five test microorganisms.Two alginates with no added disinfectant, one supplemented with chlorhexidine and two others containing quaternary ammonium compounds were tested.

Flow studies of certain dental impression materials

The Journal of Prosthetic Dentistry, 1957
Abstract A study has been made of the degree of flow exhibited by 15 different impression materials commonly used in prosthetic dentistry and the amount of flow which might be expected from these materials at various time intervals following the beginning of spatulation.

Tissue management with dental impression materials.

American journal of dentistry, 1990
The coordination of perceptive tissue management, diligent tooth preparation and prudent selection of the impression material for specific clinical conditions ensures the success of cast and ceramic restorations. The introduction of a knitted cord (Ultrapak with Astringedent) has alleviated the arduous aspects of tissue displacement and the new ...
