摘要:
A dental separator ring includes an elastic body having a first end and an opposed second end spaced from the first end. The body has three axes defined by a front to rear reference line of the body, a side to side reference line of the body, and a top to bottom reference line of the body. A first surface engager is connected to the first end of the body by a first connector, and a second surface engager is connected to the second end of the body by a second connector. The first connector allows motion of the first surface engager in all three axes, and the second connector allows motion of the second surface engager in all three axes. A third surface engager and a fourth surface engager that allow motion in all three axes may also be included in the separator ring.
