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...

Magnetic neutron scattering provides evidence for nucleation of antiferromagnetic droplets around impurities in a doped nickel oxide-based quantum magnet. The undoped parent compound contains a spin liquid with a cooperative singlet ground state and a gap in the magnetic excitation spectrum. Calcium doping creates excitations below the gap with an incommensurate structure factor. We show that w...

A technique for obtaining maxillomandibular registration for complete denture patients is presented. The maxillary rim is formed with the use of conventional techniques. The mandibular rim is made from modeling plastic impression compound on a record base formed by the patient into the neutral zone. The mandibular rim then is reheated, and the patient determines the occlusal vertical dimension ...

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...

This document describes the theory and technical details of Volume Tracking, a new method for visualization of flow measured using four-dimensional phase contrast magnetic resonance imaging (4D PC-MRI) [1]. Volume Tracking provides a new visual impression of the flow compared to particle tracing, the most commonly used method for visualization of 4D PC-MRI data. Volume Tracking uses a novel for...
