Background: In bilateral partial edentulous condition modified Mc Lean’s Impression technique is most commonly advised, this over impression procedure may be time consuming clinically and possible errors too can be induced while recording. The purpose of this study was to determine the efficacy ofsingle custom tray using medium body elastomeric impression material overmodified Mc Lean’s impress...

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...

Dental impressions are an important part of routine diagnostic and therapeutic dental procedures. Using conventional impression materials, the dentist captures intraoral details, technician uses for casts pouring. Intraoral scanners (IOS) fast, accurate more pleasant a patient than techniques became valid alternative to those Thirty-four students performed alginate digital on each other filled ...

Interocclusal recording for removable partial denture in bilateral mandibular distal extension were evaluated for the differences of the interocclusal recording material utilized during different impression techniques. The purpose of this study is to develop interocclusal recording utilizing occlusion rims with high accuracy. The intraoral model with urethane rubber mucosa with 3 metallic spher...

STATEMENT OF PROBLEM Movement of pick-up type impression copings inside the impression material during clinical and laboratory phases may cause inaccuracy in transferring the spatial position of implants from the oral cavity to the master cast. As a consequence, the laboratory technician may fabricate a restoration that requires corrective procedures. PURPOSE This in vitro study evaluated the...

PURPOSE To compare digital and conventional impression techniques in a randomized clinical trial; specifically, procedure times, patient-centered outcomes, and clinical evaluation of the restorations. MATERIALS AND METHODS Forty-two patients in need of tooth-supported single crowns and/or fixed partial prostheses up to six units were randomly allocated to one of the impression techniques. The...

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...

INTRODUCTION An accurate and passive fit of implant framework prosthesis, as well as the successful surgical operation is suggested as one of the critical requirements for long-term implant success. OBJECTIVE The purpose of this in vitro study was to evaluate the accuracy of the master cast using open tray impression technique with conventional and novel splinting materials. METHODOLOGY A m...

STATEMENT OF PROBLEM Various impression techniques have different effects on the accuracy of final cast dimensions. Meanwhile; there are some controversies about the best technique. PURPOSE This study was performed to compare two kinds of implant impression methods (open tray and closed tray) on 15 degree angled implants. MATERIALS AND METHOD In this experimental study, a steel model with 8...
