ABSTRACT:
The element is adapted to be fitted as an annular band around a tooth and to be secured to a dental appliance to hold the same in position. It includes a strip metal element having two end portions, which are adapted to overlap in the annular band, a first slide-snap fastener part, which is carried by one of the end portions and includes a tunnel member defining a tunnel passage extending longitudinally of the strip metal element, and a detent spring secured to the tunnel member and extending longitudinally in the passage, a second slide-snap fastener which is carried by the other of the end portions and includes a plurality of barblike oblique detent teeth spaced apart in the longitudinal direction of the strip metal element and movable relative to the first fastener part in a closing direction into the tunnel passage. At least part of the detent spring protrudes transversely into the passage generally at an acute angle to the closing direction and is selectively interengageable with the detent teeth in a plurality of positions, which determine respective diameters of the annular band.
