PURPOSE The aim of this study was to compare the accuracy of casts produced by 2 impression techniques and elastomeric impression materials commonly used for the fabrication of implant-supported fixed prostheses. MATERIALS AND METHODS A master model with 4 synOcta ITI implants placed unilaterally in place of the mandibular right central incisor, canine, first premolar, and first molar was con...

Background: Prediction the width of unerupted permanent canines and premolars is far important in assessing the space available to them in an attempt to prevent the future malocclusion. The present study utilized the combined mesio-distal crowns widths of maxillary and mandibular central incisors and first molars to predict the combined mesio-distal crowns widths of maxillary and mandibular can...

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...

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...

Establishing anatomic reduction of an edentulous mandible fracture is a frequently acknowledged challenge in craniomaxillofacial trauma surgery. In this study, we report a novel method for the reduction of the edentulous mandible fracture, via fabrication of modified Gunning splints using existing dentures and SMARTLock hybrid arch bars. This technique dramatically simplifies the application of...

One of the most frustrating aspects of making final impressions for crowns and bridges involves the management of finish lines that extend subgingivally. The dentist must contend with many problems like relapsing gingival tissue which can obstruct the flow of impression material into the sulcus. This is most often managed by packing retraction cord which is time-consuming, difficult and often u...

PURPOSE This in vitro study evaluated the accuracy of multiple-unit dental implant casts obtained from splinted or nonsplinted direct impression techniques using various splinting materials by comparing the casts to the reference models. The effect of two different impression materials on the accuracy of the implant casts was also evaluated for abutment-level impressions. MATERIALS AND METHOD...

Improvements in computer-aided design/computer-aided manufacturing technologies have led to multiple attempts being made simplify and improve the workflow of prosthesis fabrication for completely edentulous patients. However, most still involve conventional methods impression-making recording maxillomandibular relationships using alginate, rubber impression materials, wax materials. In case a a...

BACKGROUND This study evaluated in vivo the accuracy of metal (Smart®) and plastic (Triple Tray®) dual-arch trays used with vinyl polysiloxane (Flexitime®), in the putty/wash viscosity, as well as polyether (Impregum Soft®) in the regular viscosity. MATERIALS AND METHODS In one patient, an implant-level transfer was screwed on an implant in the mandibular right first molar, serving as a patte...
