Dentsply StarLoy N Alloy Metal

 
Features
 
Excellent mechanical properties, this alloy is characterized by its versatility.
This alloy can be covered by Starlight Ceram easily and safely.
StarLoy N is free of beryllium.
Low thermal conductivity.
Based on high melt NiCr.
Starloy N is a non-precious dental alloy.


 
Description
StarLoy N is a corrosion-resistant NiCr - based NPM deflagration alloy.
It can be veneered with all dental ceramic masses covering the CTE range from 14.4 μm/m.K (25 -600 °C ) for example Duceram Kiss, Ceramco 3. StarLoy N complies with the specifications of the standard DIN EN ISO 22674.
 
The new metal Starloy N is the perfect supplement for other members of the StarLoy line.

Direction of use
PROCESSING INFORMATION :
1) MODELLING :
 
Cover stump with stump lacquer before modeling.
The Form of the crown should correspond to the reduced tooth.
When modelling make sure not to create any sharp corners or edges.
 
2) PINNING :
If bar casting is not preferred and single crown pinning is used instead, the casting channel should have a diameter of 3 - 4 mm. The following casting channel dimensions should be maintained if the bar casting method is used -
 
CASTING CHANNEL FROM CONE
3 4 mm diameter
CASTING CHANNEL CROSSWIRE (BAR)
4 5 mm diameter
CONNECTION TO CROWNS
3 3.5 mm diameter and
5 8 mm in length.
 
3) INVESTMENT :
Any phosphate - bound investment compound for high-fusing alloys that are free of graphite can be used.
A sufficient muffle liningif necessary with several layers, is required for work with metal muffle rings.
Do not use it in cases of confirmed hypersensitivity to one or more of the metals in the alloy.
