Matrix Systems Q2

Across
A tooth that has been prepared for a class II, III, or IV restoration will have at least one proximal _____________ removed that must be replaced. A matrix band provides a temporary wall to hold the restorative material as it is being placed.
The ______________ slot of the retainer is always positioned in the mouth with the slot facing toward the gingiva.
The purpose of a matrix system is to act as a ______________ interproximal wall during the restorative procedure, restore interproximal anatomic contours, and create an external surface against which the restorative material is packed.
Either the T-band or the spot-welded band is used to fit the ______________ molars when a matrix is needed for a primary restoration.
When a posterior metal matrix band and retainer are placed, the seated matrix band should extend approximately one millimeter _____________ the gingival margin of the preparation.
The ______________ retainer with a universal band is the most common matrix system used for class II posterior restorations.
To contour a metal matrix band for posterior teeth, place the band on a paper pad and rub the inner surface of the band with a ______________ or the end of a mirror handle until the ends begin to curl.
A wrench turns the coil ______________ to tighten the band The coil cannot be manually turned with the fingers.
The universal matrix band is made of a thin, _____________ stainless steel material.
The ______________ of the tension ring of the Palodent system are placed between the band and the wedge to create a solid closure around the cavity preparation.
Down
Howe pliers, rather than an amalgam ______________, are the instrument of choice when positioning a wooden wedge.
The _____________ knob is used to increase or decrease the size of the matrix band loop after it has been placed on the tooth.
The____________matrix system produces a tight anatomic contact for composite resin materials used in the posterior teeth.
Composite resins have inorganic filler particles that can be scratched or marked by stainless steel. The newer bonding materials also can ______________ with the stainless steel bands, causing the materials to set improperly.
The ______________ system does not require a retainer to hold the band in place
The center of the matrix band should be contoured in the proximal contact area so the final restoration will have proper contact with the ______________ tooth.
First Bend the wings of the T-band to form a U-shape 4, then Slip the free end of the band through the U formation, next, Holding the free end of the band toward the facial, place the band loop on the tooth last, Holding the free end of the band toward the facial, place the band loop on the tooth.
The ______________band is used for the deeper class II preparations that require gingival extensions to compensate for the loss of a cusp.
The clear ____________matrix is used for anterior composite resin and glass ionomer restorations.
A ______________ is used to apply pressure to the apical and gingival walls of the preparation. The wedge presses the band against the tooth, causing a slight, temporary separation of the teeth.
