Matrix Preparation
(pinned version, non-precious alloy)
 
14. Fit the matrix onto the patrix, block out the undercuts towards the jaw and apply a thin coat of wax around the matrix. Insert a metal pin into the drill hole of the retention.
 
15. After duplicating replace the metal pin by a pre-fabricated ceramic pin and prepare the casting pattern as usual (leave out the patrix area). Apply a wax coat of approximate 0.5 mm to the retention part of the matrix.
 
16. When casted and finished, connect the casting pattern to the matrix by use of a metal pin.
