The results have shown that all impression materials
showed minimum change in weight while treated with Chlorox(r), whereas Practice safe(r) caused large changes in weight.

In response, the team developed HoloDent --a complete intra-oral optical system that produces a 3D reconstruction of soft and hard tissues and does not involve the use of impression materials
Kaya Dental is a new dental supplier, providing professionals with the highest quality dental impression materials
from top manufacturers, including:
The soft impression material
is molded by the pre-operative impression so as to be shaped into a tooth that has the same shape as the original tooth of the pre-operative impression.
Polyvinylsiloxanes (PVS), used as dental impression materials
, were formulated with the variation of loading combination of six types of fillers including nano-sized fumed silica.
The alginate impression materials
contain sodium alginate, calcium sulfate, trisodium phosphate, diatomaceous earth, zinc oxide, and potassium titanium fluoride, all in the form of a powder.
Several new impression materials
were introduced: Reversible hydrocolloids, Zinc oxide--Eugenol and Zinc oxide-oil of cloves.
The purpose of this study was to evaluate the stiffness of five commercially available different alginate impression materials
namely Cavex CA37(r), Cavex Color Change(r), Tulip(r), Cavex Cream Alginate(r) and TOL(r) so that one can deduce which material is the most suitable for taking accurate impressions of deep sulci and undercuts.
This is the first part of a two--part article, and explains mixing impression materials
, making preoperative dual-arch impressions, deciding in what situations to use separate arch impressions instead of the triple tray, and introduces the topic of making provisional restorations.
The literature confirms that alginate impression materials
have less stability and accuracy when the storage time of alginate increase, (13-15) but the time of contact between alginate and gypsum has not been tested before.
