AIM This study aims to determine the role of mixing techniques of polyether impression materials and efficacy of disinfection on microbial colonization of these impression materials. MATERIALS AND METHODS Polyether impression material was mixed using two methods: First by hand mixing (group I) and second using an automixer (group II) with a total of 100 samples. Four microbial strains were st...

the purpose of this study is to explore and classify the perceptions of the phenomenon of hypocrisy in organization from viewpoint of employees in a university using phenomenography, so that achieving to a deeper understanding of this phenomenon. sampling was done by maximum variation method and sample size was determined 30 people using theoretical saturation. some open semi-structural intervi...

PURPOSE This study compared tissue three-dimensional (3D) displacements during the material setting phase of two maxillary impression tray-holding techniques: clinician manual pressure and patient occlusal pressure. MATERIALS AND METHODS The resultant two maxillary casts for each of 10 edentulous patients were compared using an optical 3D measurement system. RESULTS The junction between the...

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...

OBJECTIVES The aim of this pilot study was to evaluate the efficiency, difficulty and operator's preference of a digital impression compared with a conventional impression for single implant restorations. MATERIALS AND METHODS Thirty HSDM second year dental students performed conventional and digital implant impressions on a customized model presenting a single implant. The outcome of the imp...

PURPOSE To compare the dimensional accuracy of three impression techniques- a separating foil impression, a custom tray impression, and a stock tray impression. MATERIALS AND METHODS A machined mandibular complete-arch metal model with special modifications served as a master cast. Three different impression techniques (n = 6 in each group) were performed with addition-cured silicon materials...

OBJECTIVES The objective of the following study is to evaluate the interaction between the resin materials used in immediate dentin sealing (IDS) techniques and impression materials with two different techniques to eliminate the oxygen-inhibition layer. MATERIALS AND METHODS The occlusal dentin surface of 35 human molars was exposed. The teeth were used in two Groups: Group 1 - Impression wit...
