The mass-transfer trays HighspeedTray, HighFlexiTray and SieveTray belong to a new generation of mass transfer trays that enable increase the capacity-efficiency profile and the flexibility of tray columns significantly. This increase is achieved by a special vapor and liquid distribution and contact systems installed on these trays and a combination of two different tray designs. These trays c...

A dynamic impression is a functional impression that records the functional movement of the patient's own muscle and muscle attachment. This process reduces the number of random factors. This article describes a method for making a special tray using a dynamic impression concept that was made from provisional dentures used for implant healing. The individual tray is used to make a wash-impressi...

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...

PURPOSE To compare the dimensional accuracy of three impression techniques- a separating foil impression, a custom tray impression, and a stock tray impression. MATERIALS AND METHODS A machined mandibular complete-arch metal model with special modifications served as a master cast. Three different impression techniques (n = 6 in each group) were performed with addition-cured silicon materials...

in the present study, experimental investigations about the hydrodynamics of the conical cap tray (concap tray) have been carried out. the concap tray is an innovative and novel type of cap trays. the effect of the different weir height (2.5, 5 and 7 cm) on the weeping, entrainment and the total pressure drop for the concap tray was measured, compared and correlated. the hydraulic experiments w...
