PURPOSE The aim of this in vitro study was to compare the accuracy of two different impression techniques for the All-on-Four implant therapy protocol. MATERIALS AND METHODS An acrylic resin analog for an edentulous maxilla with four internal connection implants (Replace Select, Nobel Biocare) was fabricated according to the All-on-Four protocol. A total of 40 impressions were made with diffe...

Abstract Background To investigate the preference and perception on intraoral scanning impression making among dental students. Methods Final-year students from 2019 2020 cohorts were invited to complete an online questionnaire via Google-Form. Their intraoral-scanning/impression techniques their these including ease of defect identification, infection control, need chairside support, master te...

Prosthetic rehabilitation of patients with microstomia presents a major challenge to dentist as limited oral opening makes access the cavity for any dental procedure difficult. The primary hurdle during fabrication dentures in such patient is making an impression. This article describes treatment where maxillary and mandibular custom sectional impression trays were used definitive impressions.

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...

The aim of this study was to determine quantitatively and qualitatively the inorganic particle fraction of commercially available dental elastomers. The inorganic volumetric fraction of two addition silicones (Reprosil Putty/Fluid and Flexitime Easy Putty/Fluid), three condensation silicones (Clonage Putty/Fluid, Optosil Confort/Xantopren VL and Silon APS Putty/Fluid), one polyether (Impregum S...

Treating complex cases is clinically and technically challenging, yet highly rewarding to both patient and clinician when successfully completed. Precision in the fit of the restorations, the definitive occlusal scheme, and the esthetic result are the key elements to long-term success. Clinicians should aim to achieve the same level of precision when treating these cases as they do when treatin...

Abstract: A novel dust free alginate impression material was formulated and prepared, comprising an alginate polyvinylpyrrolidone and tetraflouroethylene resins, a mixture of liquid paraffin and dimethylpolysiloxane oil as the dust generation controlling agents and processed diatomaceous earth filler which was obtained from Iranian ore. No dusting was detected during the mixing of the powde...

OBJECTIVES This study sought to evaluate the accuracy and errors of linear measurements of mesiodistal dimensions of Kennedy Class III edentulous space using cone beam computed tomography (CBCT) in comparison with clinical measurements. MATERIALS AND METHODS Nineteen Kennedy Class III dental arches were evaluated. An impression was made of each dental arch and poured with dental stone. The di...
