A practical treatise on artificial crown- and bridge-work . ollars, filling about two-thirds of the DETACHABLE BRIDGE-WORK. 259 depth of the collars with a plastic filling-material, packing it wellaround the retaining-poste; Select Buitable cusp crowns for themolar and cuspid, and place them in the ends of the hands toascertain the occlusion. If too long, shorten the cusps or reducethe bands with engine corundums or rotary files, and when thecorrect articulation is found form a small square shoulder in thelingual edge of the cuspid and in the posterior grinding-surfaceof the molar. Fill the remaining portion of the collars withplastic mixed somewhat thinner than the first lot, and set thecusp crowns in position. If there are antagonizing teeth themere closing of the patients jaws will force the crowns to there are no antagonizing teeth the crowns can be readilytapped to place with the mallet, using a piece of wood as adriver. Allow the filling-material to set firmly, trimming offany excess which may exude around the collars. Fig. Bridge supports or piers constructed on this plan are strongand durable, and likely to withstand any strain. Take animpression, and proceed to fit seamless collars to telescope overthose already set upon the cuspid and second molar roots. Itwill be remembered that these collars are so made that each sizetelescopes into the next higher series. If the proper sizes areselected for the outside or female bands, the work of fitting isreadily and quickly accomplished, forming tubes which slideeasily over the supporting piers, and at the same time fit is only necessary to take care in shaping the tubes not to drivethem too far up on the mandrels and thus stretch them so as todestroy the fit. To the outer end of each of the tubes solder asmall piece of gold plate, forming partial caps so placed as torest when in position upon the shoulders previously cut in thecusp crowns. Adjust a truss bar of half-round gold wire, to thee
