Indian Matrix Bands – Stainless Steel No. 8 (Straight)

Indian Matrix Bands – Stainless Steel have a good rigidity.
It has the ability to be contoured.
It prevents gingival excess.
It has the strength to offer resistance for condensation.
Easy Removal from the tooth.

Indian Matrix Bands Stainless Steel No.8 (Straight) is a properly encountered piece of metal with the primary function of the matrix is to restore anatomic proximal contours and contact areas.
A properly placed matrix should: Be rigid against the existing tooth structure.
Matrices are placed for interproximal restorations to aid in restoring normal contour and contact areas
and to prevent extrusion of restorative materials into gingival tissues.

INDICATION –
The matrix bands are used in Class II restorations.
Used to support and give form to the restoration during its placement and hardening.

Material: Stainless Steel

Pack Of 12 Bands

Fold the band to form a loop notice that when the band is folded, one edge has a smaller circumference than the other this design accommodates the difference in tooth circumferences at the contact and gingival levels.
There are two main rules for correct placement of the matrix system on the tooth:
Open end of the retainer head is ALWAYS placed toward the gingiva.
Smaller circumference of the band is always placed toward the gingiva.
Based on the two rules above, the following is also true:
The occlusal edge of the matrix band must be placed in the retainer with the occlusal edge facing the retainer.
In the LRQ & ULQ, the screw side of retainer is faces the buccal surface of the tooth;
in the URQ & LLQ, the flat side of the retainer faces the buccal surface of the tooth.
These rules serve as a guide to how the matrix band must be positioned in the retainer.
With the rules in mind, place the two ends of the band in the slot of the locking vise (occlusal edge of the band facing the retainer)
and position the band in the correct slot of the head, such that the rules above will be satisfied. Turn the small knob clockwise,
lowering the screw into the vise and thus locking the matrix band within the retainer.
Fit the matrix onto the tooth.
The band should be seated around the tooth such that:
1. The occlusal portion of the band extends 1.5 – 2.0 mm above the marginal ridge of the adjacent tooth
and the Cavo surface margin–this allows for proper condensation of the amalgam in the marginal ridge area.
2. The gingival portion of the band extends 0.5 mm below the gingival CSM.
Tighten the matrix band around the tooth.
To tighten the matrix band around the tooth, turn the long knob; this will pull the matrix band up along with the sliding body,
thus decreasing the diameter of the matrix band and tightening it around the tooth. Tighten the matrix as much as possible around the tooth, this allows for proper amalgam condensation and contour development.
To check that the explorer is tightly adapted to the gingival surface, use an explorer and try as hard as possible to place the tip between the
matrix band and the gingival Cavo surface margin; you should not be able to do so. This also helps to remove any unsupported enamel left in the area.
Place the wedge, once it is seated tightly in the gingival embrasure, loosen the matrix band slightly by turning the knob 1/4 of a turn.
This prevents the matrix band from being too tight, which may lead to an open contact and may hinder proper condensation of the
amalgam into the proximal Cavo surface margin areas,
Finally use a spoon excavator or burnisher to burnish the matrix band to the adjacent proximal contact area.
