Dental Impression Materials and Techniques
Dental Clinics of North America, 2017Dental impression making is the process of creating a negative form of the teeth and oral tissues, into which gypsum or other die materials can be processed to create working analogues. Contemporary dentistry generates new information every year and digital dentistry is becoming established and influential.

It is clear that many impression materials are available to the veterinary dentist. They each have different inherent properties, handling characteristics, and indications for use. A thorough understanding of these concepts is essential if the veterinarian and laboratory technician are to produce meaningful and accurate reproductions of oral structures.

Reactions to dental impression materials
Contact Dermatitis, 1977In the department of prosthetic dentistry at Groningen, during the past four years, approximately 2,000 persons have been treated with Scutan, an epimine plastic for temporary crowns and bridges and Impregum, a polyether impression material. A total of ten patients complained of untoward reactions. Patch tests with the basic materials were performed on

Study of the potential cytotoxicity of dental impression materials
Toxicology in Vitro, 2003The aim of this study was to assess the cytotoxicity of tow types of impression dental materials: polyethers (Impregum Penta, Permadyne Penta Heavy and Light) and vinyl polysiloxanes (Elite Mono Tray, Medium, Low viscosity and Elite H-D Putty). Their cytotoxic effects were studied by indirect and direct tests.

Dental Impression Materials: Reactor Response
Advances in Dental Research, 1988A review of the literature reveals an abundance of research papers which are focused on the physical properties and "simulated" clinical performance of impression materials. The three major developments during the past two decades were: (1) the introduction of the dimensionally stable addition silicones, (2) the development of dustless alginates, and (

A rare allergy to a polyether dental impression material
Clinical Oral Investigations, 2011Polyether impression materials have been used in dentistry for more than 40 years. Allergic reactions to these materials such as reported in the 1970s ceased after replacement of a catalyst. Very recently, however, patients have started to report symptoms that suggest a new allergic reaction from polyether impression materials.

Compatibility of alginate impression materials and dental stones
The Journal of Prosthetic Dentistry, 1971Abstract 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).

Tear and rupture of elastomeric dental impression materials
Biomaterials, 1984The curing time dependence of the tear energy, tensile strength and ultimate extension ratio of a range of characterized elastomeric impression materials was investigated. This variation of tensile strength and ultimate extension ratio was correlated with the development of the network structure.

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
