摘要：
A matrix ring includes a body that has a yoke, a first side arm extending from a first end of the yoke, a second side arm extending from a second end of the yoke, a first tine extending downwardly and inwardly from the first side arm, and a second tine extending downwardly and inwardly from the second side arm and converging toward the first tine. A first tip covers at least a portion of the first tine, and a second tip covers at least a portion of the second tine. The first and second tips are each bifurcated by a tine gap to provide a first tip finger and a second tip finger.
