SQUARE SPRUE : THE PRINCIPLE
It fits into a special refractory alloy firing peg (supplied with the kits), allowing this way to hang up the bridge during the porcelain firings without any risk of dropping your work.
It is possible to fire bridges – even precious alloy – up to 6-8 units hanging them up with only one sprue without risk of distortion after firing !
MINI WAXTIC
For continuing with the same research of ergonomics as in the wax-pontics, Mini- Waxtic is a small wax sprue (square profile) that you can position on your wax copings. Once casted in alloy, it will be extremely useful and comfortable for holding the object.
