abstract introduction: impression making is one of the most important steps in fixed prosthodontics. due to contra-dictory opinions on the issue of the accuracy of silicone impression material as a function of technique, this study was carried out to assess the dimensional accuracy of master casts made by rapid silicone material as a function of three impression techniques: with 2mm space, with...

Introduction: Flabby or fibrous ridge is one of the consequences of long term wearing of complete dentures. It can develop where hyperplasic soft tissue replaces the alveolar bone and is a common finding, particularly in the upper anterior region of long term denture wearers. Forces exerted during impression making can result in distortion of the mobile tissue unless managed appropriately; such...

PURPOSE The purpose of this impression technique is to overcome the problem associated with restricted mouth opening in association with high arched palate by employing pneumatic impression technique using latex balloon. METHODS A stock tray was modified with auto polymerizing acrylic resin. On the modified tray, a latex balloon was attached with aid of cyanoacrylate. The outlet of the balloo...

The present research examines how the match between encoding and recall contexts influences recall performance. Memory research has shown that recall performance can be impaired when a subset of the studied stimuli is presented at recall (the part-set cuing effect) or when the recall process is carried out in a collaborative way (collaborative inhibition effect). In 4 experiments we manipulated...

Impressions of footwear are commonly found in crime scenes. The quality and wide variability of these impressions and the large number of footwear outsole designs makes their manual analysis time-consuming and difficult. The goal of this research was to develop new computational methods that will eventually assist the forensic footwear examiner in the U.S. Two scenarios encountered by the foren...

C C Modeling plastic impression compound (MPIC) is defined as a thermoplastic dental impression material composed of wax, rosin, resins, and colorants.1 Low-fusing compound (type 1) is used for border molding and impressions. Flow and reproducibility of surface detail are important characteristics of these materials.2 Border molding with MPIC can record accurate border detail; however, it can b...
