Accuracy of the second pour casts using dual-arch trays.
OBJECTIVE To compare, in vitro, the accuracy between dental stone casts obtained from the first and the second pour using metallic (Smart) and plastic (Triple Tray) dual-arch trays. MATERIAL AND METHODS The impressions were taken using Flexitime® vinyl polysiloxane from a typodont model with a mandibular right first molar prepared for a full crown. Ten impressions were made with each tray and...
متن کاملAccuracy of stone casts obtained by different impression materials.
Several impression materials are available in the Brazilian marketplace to be used in oral rehabilitation. The aim of this study was to compare the accuracy of different impression materials used for fixed partial dentures following the manufacturers' instructions. A master model representing a partially edentulous mandibular right hemi-arch segment whose teeth were prepared to receive full cro...
متن کاملDimensional Accuracy of Stone Casts Obtained with Multiple Pours into the Same Mold
Aim. The aim of the present study was to compare the dimensional accuracy of stone casts obtained with vinyl polysiloxane molds through the double-impression technique with three pours into the same mold. Methods. A stainless steel master model was constructed simulating a three-unit fixed prosthesis. Twelve impressions were taken of this master model with addition silicone, using the double-im...
متن کاملeffect of storage time of extended-pour and conventional alginate impressions on dimensional accuracy of casts.
some manufacturers claim to have produced new irreversible hydro-colloids that are able to maintain their dimensional stability during storage. the present study evaluated the effect of storage time on dimensional stability of three alginates: hydrogum 5, tropicalgin and alginoplast.in this experimental in-vitro trial, a total of 90 alginate impressions were made from a dentoform model using hy...
