Background. Addition silicones are popular as dental impression materials and are used in bite registration procedures. Objective. This study aimed to compare the postsetting elasticities and other mechanical properties of thirteen addition silicone interocclusal recording materials. Materials and Methods. The following materials were investigated: Colorbite D, Futar D, Genie Bite, Jet Blue Bit...

A product available commercially for making dental impressions, Jeltrate Plus, was evaluated as a tissue equivalent bolus material. Jeltrate Plus was found to be tissue equivalent in 6 and 15 MV photon energy beams and 6, 12, and 20 MeV electron energy beams. As a first step, different preparations for making the bolus material were investigated and an optimal mixture was determined to be two p...

C C Modeling plastic impression compound (MPIC) is defined as a thermoplastic dental impression material composed of wax, rosin, resins, and colorants.1 Low-fusing compound (type 1) is used for border molding and impressions. Flow and reproducibility of surface detail are important characteristics of these materials.2 Border molding with MPIC can record accurate border detail; however, it can b...

PURPOSE The aim of this study was to evaluate and compare the inter-operator reproducibility of three-dimensional (3D) images of teeth captured by a digital impression technique to a conventional impression technique in vivo. MATERIALS AND METHODS Twelve participants with complete natural dentition were included in this study. A digital impression of the mandibular molars of these participant...

With the techniques of computer-aided design and computer-aided manufacturing (CAD/CAM) being applied in the field of prosthodontics, a concept of intraoral digital impressions was put forward in the early 1980s. It has drawn comprehensive attention from dentists and has been used for dental prosthesis fabrication in a number of cases. This new digital impression technique is expected to bring ...

Impression procedure forms the basis of a successful Removable Partial Denture however, in distal extension bases the residual ridge must be recorded in functional form and the remaining natural teeth in an anatomic form. Zinc oxide eugenol impression paste is a material of choice for functional impression whilst irreversible hydrocolloid is suitable for an anatomic impression. Therefore two-pa...
