Question

The larger side of the universal matrix band loop is always directed toward which part of the tooth?

1) Mesial
2) Distal
3) Occlusal
4) Gingival

Answer 1

The larger side of the universal matrix band loop is always directed toward the occlusal surface of the tooth to accommodate the larger surface area for dental restorations.

Step-by-step explanation:

The larger side of the universal matrix band loop is always directed toward the occlusal surface of the tooth. This orientation is crucial because the matrix band is used to recreate the proper shape of a tooth when a dental filling is placed. The occlusal surface is the top surface of the teeth used for chewing, and the matrix band needs to be wider at this end to accommodate the larger surface area that is often involved in restorations. In contrast, the narrower side of the loop should be oriented toward the gingival side, where the tooth and the gum meet.
