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.

Aspiration of dental impression material – a case report
Dental Update, 2017Aspiration of dental impression material is a rare but potentially serious complication of routine care. Prior to this case report the authors found three other reports of impression material aspiration. The following report describes the presentation, management and sequelae of a case. CPD/Clinical Relevance: Routine impression-taking is a procedure

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 ...

Rheological Properties of Some Materials Used for Dental Impression
Journal of Biomimetics, Biomaterials and Biomedical Engineering, 2017The dimensional stability of dental impression materials is one of the variables that contribute to the accuracy or to the inexactitude of dentures. The rheological properties of several dental impression materials were determined by amplitude and frequency sweep tests.
