Flow studies of certain dental impression materials
The Journal of Prosthetic Dentistry, 1957Abstract 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.

The influence of dental gloves on the setting of impression materials
British Dental Journal, 1995The increased wearing of gloves during dental treatment has created new problems for general dental practitioners. One of these is the retarded set or total inhibition of addition silicones caused by natural latex gloves. This study was designed to test different gloves and impression materials in common use. Eight latex gloves, selected with different

Elastic and plastic properties of elastic dental impression materials
Dental Materials, 1985Abstract Strain in compression, compression set, stiffness and Shore A hardness of 36 brands of elastic dental impression materials have been determined. There was no correlation between compression set and the other properties tested, while statistically highly significant correlations were found between strain in compression, stiffness and Shore A ...

Development of an Impression Material with Antimicrobial Properties for Dental Application
Journal of Prosthodontics, 2019AbstractPurposeTo evaluate the antimicrobial activity and physico‐mechanical properties of an irreversible hydrocolloid in which nanostructured silver vanadate decorated with silver nanoparticles (AgVO3) was added at various concentrations (0% ‐ control, 2.5%, 5%, and 10% by weight).Materials and MethodsThe agar diffusion method (n = 10) was used to ...

Visco-elastic properties of dental elastomeric impression materials
Biomaterials, 1986The visco-elastic properties of a number of set elastomeric impression materials were determined using a torsional pendulum apparatus, i.e. the real (G1) and imaginary (G2) parts of the complex shear modulus and the mechanical loss tangent (Tan delta). Comparison with published data on tension and compression set for these materials showed that whilst ...

Accuracy of a new elastomeric impression material for complete‐arch dental implant impressions
Journal of Investigative and Clinical Dentistry, 2018AbstractAimThe aim of the present study was to assess the accuracy of multi‐unit dental implant casts obtained from two elastomeric impression materials, vinyl polyether silicone (VPES) and polyether (PE), and to test the effect of splinting of impression copings on the accuracy of implant casts.MethodsForty direct impressions of a mandibular reference

Measurement of pressure ulcer volume using dental impression materials: suggestion from the field.
Physical Therapy, 1989Understanding of the healing rates of deep pressure ulcers may be enhanced in future studies by relating changes in wound volume to changes in WSA. In this report, a type of dental impression material, vinyl polysiloxane, was used to produce a model of ...

Effect of mixing ratio on properties of elastomeric dental impression materials
Dental Materials, 1986Abstract The effect of deviations from the standard base-catalyst mixing ratio of four single phase elastomeric impression materials on working and setting time, compression set and Shore A hardness was studied. Depending on the presence of the inhibitor polysiloxane in the base or the catalyst paste of addition curing silicones the curing rate was ...
