' This part of the Work not only requires skill to be obtainedlonly by long-end carei1tl study and experie nce, but its proger performanoe takes much timeand undivi ed. attention ,and sets of artificial teeth are mai1i1yf9r this reason, more expensive than is warrantedby the cost of materi al the time actually occupied. in fitting them t the no uth of the patient.

The curved bands thus formed, are subsequently. bent to conform" with the contour of the gum as shown in Figures 8 and 9.

The teeth 5 have transverse slots 8 to which the bands are fitted "and it will be apparent that when the teeth are strung on the band in their regular anatomical order and the bands are bent at their ends to prevent of relative displacement of the teeth, the band and the teeth provide collectively a set "of teeth which as an entirety may be fastened on a dental model, and that when both'the'upper and lower sets are thus applied, correct anatomicalarticulation is assured; I

The upper'and lower sets of teeth after having: been-assembled as hereinabove described, are fastened together in anatomically correct relative positions by means of wire loops 9' which engage the bands at intervals between the teeth and which after the sets have been fastened in the wax plates on the dental models, are broken and removed.

It will be understood that the bands which support the teeth may be of any desired form in "cross section, and that their protruding ends instead of being'bent to hold the teeth in place, may, for the same purpose, be provided with nuts'or knobs of solder or cement.

' IIrFlgL1r 10 of the drawings, the band 10 is placed exteriorly of the teeth which are secured thereto, as at 12, by cement or other suitable means.

In Figure 10, the holding element is made in sections which are placed between the teeth of each set.

The sections are preferably made in the form of pins 13 which are curved for alinement in an imaginary compensating curve and which fit snugly in sockets 14 in the sides of the teeth.

In the use of my invention, the two sets of teeth arranged and fastened together as shown and described, are supplied to the dentists in various sizes, shapes and shades to meet different requirements.

The operator places the sets on the models in a dental articulator, as usual, and after I the wax in which they are set, has hardened,

the wires which held the sets together, are

cut and removed.

. Owing to the conformity of the bands on "which'the teeth are assembled, with the compensating curve and the contour of the gums to which the sets are fitted, the correct position and relative arrangement of the teeth on the models is "obtained without individual adjustment and without the measurements, calculations and care ordinarily required;

The pliability of the bands permits of the sets being fitted to gums of irregular form in any given size.

In case but part of the teeth of either set are required, the other. teeth are removed from the holders before the sets are fastened in the mouth plates, and in the event of it being necessary to replace one or moreof the teeth on account of wear or breakage,

.the operator cuts through the porcelain or other material of which the teeth are made, to the slot through which the band passes, removes the broken or worn tooth and replaces the same with a tooth which is recessed to fit upon the band.

After the new tooth is positioned on the band between the others, its recess which'is, open at the upper or lower end thereof, is

filled with a vulcanite or other suitable material, as indicated at 15 in Figure 6 of the drawings.

The channeled teeth may be re-inforced by means of a metal-bushing which is fitted? and baked in the channel throughwhich the metal band passes, as shown at 16 in' Fig:
