the use of multiple implants in the same jaw requires a detailed knowledge of abutment angulation. the position and angulation of the abutments play an important role in treatment planning and fabrication of the custom tray. therefore diagnostic casts that contain cover screws may cause problems during implant therapy. the current article describes a technique for making a preliminary cast with...

The study investigated the effect of observational goals (i.e., impression formation and memory) on the process of observing ongoing behavior of others. Specifically, the amount of behavior extraction was studied. Forty-nine subjects were randomly assigned to impression and memory groups, and asked to watch a ten-minute video clip featuring a male actor in daily activities. The subjects in the ...

A fibrous or flabby ridge is a superficial area of mobile soft tissue affecting the maxillary or mandibular alveolar ridges. Restoration of such ridges often requires special consideration in impression making. Masticatory forces can displace this mobile denture-bearing tissue, leading to altered denture positioning and loss of peripheral seal. Forces exerted during the act of impression making...

One critical and to date understudied social psychological construct with significant implications for technology-mediated distributed work is impression formation. Forming useful impressions of each other is crucial for coworkers to avoidmistrust, misattribution, and conflict, and thereby, work effectively and productively. In this theoretical review paper I systematically outline how elements...

The purpose of this study was to synthesize biomaterials from daily dental waste. Since alginate impression material contains silica and calcium salts, we aimed to synthesize calcium silicate cement from alginate impression material. Gypsum-based investment material was also investigated as control. X-ray diffraction analyses revealed that although firing the set gypsum-based and modified inves...

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...
