VS-3 Instructions |
|
The VS3 Patrix is waxed onto the copings. If the Short
Patrix is used, the SV paralleling mandrel should be
used. A lingual rest & arm is recommended. |
|
|
|
|
|
 |
|
|
|
|
|
|
|
The patrix can be reduced by about a third in height.
After casting and fitting, polish the attachment
lightly. |
|
|
|
|
|
 |
|
|
|
|
|
|
|
The model is duplicated with the duplicating matrix. The
undercuts are blocked out and the case is duplicated. |
|
|
|
|
|
 |
|
|
|
|
|
|
|
After the refractory model of the case is created, the
wax matrix housing is slipped over the refractory
matrix. |
|
|
|
|
|
 |
|
|
|
|
|
|
|
The chrome cobalt framework is waxed over the refractory
model onto the wax matrix housing. It is recommended to
have a lingual arm. |
|
|
|
|
|
|
|
 |
|
|
|
|
|
|
|
The framework is then cast and fitted. A light deplating
is usually required. Acrylic is added as usual. |

VS-3 Castable Housing Instructions |
|
The VS-3 Patrix is cast onto the copings using
techniques described by the VS-3 instructions above.
|
|
|
|
|
|
 |
|
|
|
|
|
|
|
The yellow matrix is placed on the patrix and the VS-3
Matrix Housing is slipped over. |
|
|
|
|
|
 |
|
|
|
|
|
|
|
Retention beads or crystals are placed on the
cylindrical part of the housing and the lingual arm is
fabricated using bredent Pi-Ku-Plast resin. |
|
|
|
|
|
 |
|
|
|
|
|
|
|
The housing is removed from the model and the matrix is
removed from the housing. The housing is then cast;
ideally in the same metal as the copings. |
|
|
|
|
|
 |
|
|
|
|
|
|
|
After casting, the housing is finished and fitted on the
model. The Pi-Ku-Plast resin creates a precise
replication of the lingual arm. |
|
|
|
|
|
 |
|
|
|
|
|
|
|
The VS-3 Duplicating Matrix Housing is placed over the
housing, all undercuts are blocked out and the case is
prepared for duplicating. |
|
|
|
|
|
 |
|
|
|
|
|
|
|
After the refractory model is created, the wax housing
is slipped over the refractory duplicating matrix. |
|
|
|
|
|
 |
|
|
|
|
|
|
|
The chrome cobalt framework is waxed onto the matrix
housing. Bredent retention beads or cyrstals can be used
to create a more retentive surface. |
|
|
|
|
|
 |
|
|
|
|
|
|
|
Vaseline is brushed onto the model as a separating agent
to keep the bonding agent from adhering to the model. |
|
|
|
|
|
 |
|
|
|
|
|
|
|
After the overcasting is fitted, DTK Adhesive is placed
into the wax housing (as seen above) and onto the
retention tail of the matrix housing. |
|
|
|
|
|
 |
|
|
|
|
|
|
|
The partial framework is pressed onto the model firmly.
Excess adhesive should be cleaned off the model and
frame. |
|
|
|
|
|
 |
|
|
|
|
|
|
|
This shows the final product. Since both metals are of
the same type where the partial is removed & inserted,
the case is optimally biocompatible. |

VS-3 SV Instructions |
|
The VS3 SV Patrix is waxed onto the copings using SV
paralleling mandrel. A lingual arm is not needed. |
|
|
|
|
|
 |
|
|
|
|
|
|
|
The patrix can be reduced by about a third in height.
After casting and fitting, polish the attachment
lightly. |
|
|
|

|
 |
|
|
|
|
|
|

model onto the wax matrix housing. |
|
|
|
|
|
|
|
|
|
 |
|
|
|
|
|
|
|
The framework is then cast, deplated and fitted. The
matrix is inserted using the insertion pin. |
