It was previously reported that pressures produced during compression of impression materials between parallel disks were affected by several factors, and that hydrodynamical analyses well characterized the results of experiments. The present study was undertaken to measure and theoretically demonstrate pressure distributions during mechanical impression making of a maxillary edentulous cast an...
The handling of vinyl polysiloxane (addition silicone) impression putties with latex gloves is said to interfere with the setting of these impression materials. The aim of this study is to evaluate the effect of handling techniques on the setting of vinyl polysiloxane impression putties using several types of gloves. The setting of these materials was evaluated by means of an elasticimeter. Fou...
Advanced materials and fractal design concepts form the basis of a 3D conformal electronic platform with unique capabilities in cardiac electrotherapies. Fractal geometries, advanced electrode materials, and thin, elastomeric membranes yield a class of device capable of integration with the entire 3D surface of the heart, with unique operational capabilities in low power defibrillation. Co-inte...
Impression procedure forms the basis of a successful Removable Partial Denture however, in distal extension bases the residual ridge must be recorded in functional form and the remaining natural teeth in an anatomic form. Zinc oxide eugenol impression paste is a material of choice for functional impression whilst irreversible hydrocolloid is suitable for an anatomic impression. Therefore two-pa...
Pierre robin sequence is characterized by the triad of mandibular micrognathia, ‘U’ shaped cleft palate, and glossoptosis. Infants with this condition usually present airway obstruction feeding difficulties. This in turn leads to low weight nutritional deficiencies which might delay surgical intervention for same. case report describes a one-month-old infant Robin presenting difficulty nasal re...
Alginates are classified as elastic impression materials. Within this elastic category it is further subdivided into irreversible hydrocolloids. The reason they are referred to as irreversible is due to the fact that once set in gel form they cannot convert back into sol form. They are widely used in contemporary dentistry for impression making especially in partially edentulous subjects. One o...
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 ...
