Glove over glove technique for manipulation of vinyl polysiloxane impression material with latex gloves
Despite prior recommendations for removal, latex gloves remain prevalent in dental clinical practice because of puncture resistance, durability, and user satisfaction.[1] However, latex gloves can impair polymerization of vinyl polysiloxane impression material (VPS) thus, resulting in inaccurate and distorted impressions, which may require the clinician to repeat the impression procedure leadin...
متن کاملEvaluation of the accuracy, precision and validity of hydrophilic vinyl polysiloxane impression material for bite mark analysis
The present study was undertaken to assess the accuracy, precision and validity of hydrophilic Vinyl Poly Siloxane [VPS] impression material for bite mark documentation and analysis. Medium body VPS impressions of maxillary and mandibular anterior teeth among thirty subjects were taken and dental stone casts prepared. Hollow volume overlays were made and metric analysis was done using advanced ...
متن کاملMaterial Conformity and Bactericidal Characteristics of High-Density Ozone Disinfection in Vinyl Polysiloxane Impression and PMMA Dentistry Fillings
Disinfection was investigated in high-density ozone produced by dielectric barrier discharge under atmospheric pressure. Disinfection was studied on three-dimensional carriers made of hydrophilic vinyl-polysiloxane impression material and granular acrylic resin used for oral surgery. Experimental results indicate disinfection of spore-forming bacteria: Geobacillus stearothermophilus and Bacillu...
متن کاملDistortion of disposable plastic stock trays when used with putty vinyl polysiloxane impression materials.
STATEMENT OF PROBLEM Impressions are made using high-viscosity putty vinyl polysiloxane impression materials in conjunction with disposable plastic stock trays. The impression materials have been shown to be dimensionally stable. However, it remains unclear if the disposable plastic stock trays are rigid enough to resist deformation thus yielding potentially unreliable results. PURPOSE This s...
