A practical treatise on mechanical dentistry . ment of the neck of the root should besecured. For this purpose Dr. A. I. F.

It is very simple to adjustand operate, and has the advantage over other instruments of thiskind, that, as you do not have to twist the entire instrument, thewire does not incline to slip off the root or lacerate the gum. Dr. Buxbaum gives instructions for using his dentimeter asfollows: Pass one end of a soft wire through tube at C, as shownin Fig. 2 of accompanying illustration, and wrap once around knobD. Pass the other end of wire through tube at E, as shown inFig. 2, and wrap around knob F. Place the loop H around thetooth or root. While unscrewing the screw, by holding milled nutB between the thumb and forefinger of right hand, you must makeconstant traction on loop around the tooth by gently pulling on Fig. barrel A, held between thumb and finger of left hand; this will givea perfect twist, as shown in Fig. 3. Unfasten ends of wire from theknobs D and F and withdraw from dentimeter. The result isshown in Fig. 4. Other and simpler instruments for taking measurements of teethor roots have been devised, notably those by Dr. Edward C. Kirk,and Dr. Geo. M. Weirich, of Philadelphia, which are shown inFig. 388. 4. In order to transfer this measurement accurately to the band-ing material, cut the wire loop in the center and spread the endsin opposite directions, as shown in Fig. 389. It is then laid onthe piece of gold to be used for the band (which should be 22-caratand about 30 gage) ; this should be cut the exact length of the ivire, 5o6 MECHANICAL DENTISTRY. \u and about }i of an inch in width, unless for special reasons it isnecessary to have it wider.
