Cast was duplicated with Agar-Agar and wax pattern
with a bracing arm on 13 and 25 was prepared over it (Figure 4).
In most patients with unilateral ear defects, when a CIT was used to make an ear, orientation of the wax pattern
took at least 2 to 3 h due to increased distortion.
To achieve a wax pattern
as high dimensional accuracy is important to accomplish an optimization of casting temperatures.
The key difference in the new method is that wax pattern
is produced with an integral textured surface.
Because Biomet engineers must ship their patterns to an out-of-state foundry, they did not want to use wax patterns
After extensive research and testing with the 3-D Printer, Sirona has announced plans to use 3D Systems' InVision([R]) DP 3-D Modeler to fabricate inCoris WAX patterns
as part of Sirona's infiniDent service beginning in March 2008.
Making the wax patterns
has been one of the more complicated aspects of this whole project," Singer said.
were fabricated as per the definitive values of temporaries, casting was done and the metal coping were tried in the patients mouth.
Results show that the accuracy of caps of CrCo-alloy, produced by SLS and by investment casting from DoD wax pattern
, is comparable, the absolute deviation ranging from 0.
Alternating layers of slurry and stucco surround the wax pattern
until a coating almost a half-inch thick builds up.
of the prepared abutments were made and casting was done with Ni-Cr alloy, trimmed, sandblasted, finished and polished.
This cast was again surveyed and wax pattern
was made for fabrication of cast partial denture frame work (fig: 7).
