This article describes the clinical procedures for a modified putty-wash impression technique. In this method, the hydraulic pressure induced from planned flowing the wash material from the inner surface of putty impression toward the vestibules pull over the gingival tissues covering the finishing line. This simple method reduces the need to using retraction cord in normal depth finishing line...

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...

Accurate impression is a main requirement for obtaining passive fit of restorations. The aim of this case report is an alternative technique in using closed-tray impression posts for open-tray impression technique for exemplification at a patient that can have limited interocclusal vertical space. After osseointegration, 7 implants examined in edentulous maxilla, open-tray impression technique ...

background: accurate impression making is an essential prerequisite for achieving a passive fi t between the implant and the superstructure. the aim of this in vitro study was to compare the three-dimensional accuracy of open-tray and three closed-tray impression techniques. materials and methods: three acrylic resin mandibular master models with four parallel implants were used: biohorizons (b...

objectives: the aim of this study was to compare the accuracy of dental implant impressions obtained by a combination of different impression techniques and viscosities of polyvinyl siloxane (pvs). materials and methods: four parallel fixtures were placed between mental foramina in a master model of lower dental arch. three different viscosities (putty/light body, medium body/light body, and mo...

AIM OF THE STUDY To evaluate and compare the linear dimensional changes of the three representative polyvinyl siloxane (PVS) impression materials and to compare the accuracy of single mix with double mix impression technique. METHODOLOGY A study mold was prepared according to revised American Dental Association specification number 19 for nonaqueous elastic dental impression materials. Three ...

A study was conducted to compare tissue displacement resulting from different techniques and impression materials for distal-extension ridges. Impression techniques used were Applegate's functional fluid wax and a single-impression technique with mercaptan rubber. A mucostatic impression technique using irreversible hydrocolloid served as control. The results showed a statistically significant ...
