A dental appliance for use with a variety of different sizes and shapes of elongated wire-like members including: a metal tubular member for attachment to a band which band encircles a tooth for support and with the metal tubular member forming an open passage extending from one end of the tubular member to the other end of the tubular member. The open passage has a greater height than width and with the passage large enough to receive different sizes and shapes of wire-like members. An insert member has a size in one direction approximately the same as the width of the open passage and having a size in the other direction substantially equal to one-half of the height of the open passage so that two inserts substantially fill the open passage. Each insert also forms an elongated passage having a cross-section smaller in size than one-half of the cross-section of the open passage through the tubular member, thereby providing for a variety of different size passages through the combination of the tubular member and one or two of the inserts within the tubular member.
