|
 |
Subgingival prep. A large wedge would tend to indent a mylar strip, and it
would be hard to achieve a subgingival seal. |
|
 |
Greater
Curve "Wide" in place. The matrix was secured around the tooth. Access
window was cut with a carbide. Rounded contour burnished in. |
|
 |
Ready
for cut back.

Final
restoration.

Case B |
|
 |
Class
III prepped and ready for fill on tooth #10.
|
 |
Greater
Curve tofflemire band in place. Retainer for the matrix has been placed on
the labial. Due to the arc of the Greater Curve band, the cavity prep is
very accessible. A portion of the band as been cut away on the lingual
providing additional access. A contact opening is created with a small
football finishing bur using a side to side motion. The transition from the
periphery of the opening to the adjacent tooth is imperceptible.
|
 |
The
cavity prep has been filled. The bond to the opposing contact is easily
broken with a metal spatula.
The bond
was weak due to its small size, and the bond was against the smooth surface
of the adjacent tooth contact.

 |
Finished
restoration at the distal of tooth #10.
Note the
rounded contour at the distal that can be accomplished with the Greater
Curve system.
The
mesial was previously restored with the traditional mylar strip and a wood
wedge.
As
expected the mesial contour is flattened leaving a black triangle.
