The aim of the present paper was to review the literature concerning the dimensional stability of dental elastomeric impression materials, to support recommendations to control the variables that influence the accuracy of these materials. An electronic search of the Scopus and PubMed databases was performed in November 2010. Articles were selected according to the following inclusion criteria: ...

Esthetic treatment of a single darkened tooth represents a great challenge to the dental practitioner. The properties of dental ceramic-colour stability, mechanical strength, clinical longevity, esthetic appearance and compatibility with periodontal tissues-make this material a good choice for such treatment. We present a case of restoration of a single, highly darkened anterior tooth with a fe...

Introduction: This clinical case aimed at showing the designing procedure for Removable Partial Denture (RPD) framework from an optical impression. The patient presented partially edentulous mandibular arch (Kennedy Class III) where RPD was planned for economic reasons. Optical impression was chosen due to the presence of a strong gag reflex and a small mouth opening. The impression was then se...

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 thermoplastic impression material Adaptol (J.F. Jelenko & Co.) is used for the impression of denture and has attained good results. But the accuracy of the impression material is not distinct. The purpose of this study was to investigate the influence of handling temperature on dimensional accuracy of the impression material. Part 1. Impressions were made with Adaptol and custom trays. Accura...

Traditionally, dark-cure (cold-cure) acrylic resin is used as pattern material for cast post and core. A new post system that incorporates a specially designed plastic support rod and a thermoplastic resin has been introduced to the market and is claimed to simplify the procedure for cast posts fabrication. The aim of the present work was to evaluate the dimensional accuracy and detail reproduc...

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...

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 ...

AIM To demonstrate the clinical feasibility of autoclaving certain silicone impression materials in order to avoid potential cross-contamination during handling, transport, and subsequent processing. BACKGROUND Semicritical devices are recommended to be treated at least with high-level disinfectants or actually steam sterilized at 134°C. To date dental impressions have been disinfected rather...
