The impression is then thoroughly coated withsandarac varnish, after which it is dipped for a moment in water,and filled with a wet mixture of one part marble-dust with twoparts of plaster; using great care to perfectly fill the caps andmolds of the teeth. Wait until this mixture has become quitehard; remove the cup, and with a suitable knife chip oft theplaster without marring the cast; secure a good articulating Fio. impression and transfer it to the east to obtain an exact repro-duction of tlie relative occlusions of all the teeth such an articulation in hand, and with the means alreadydescribed for swaging gold or platinum plate to fit the cusps andarticulating surfaces of either the natural or artificial teeth, itshould be within the capacity of any competent dentist to com-plete a suitable bridge; although there are practical points thatcan only be imparted by clinical instruction and actual demon-stration in the mouth. Such a bridge is shown in position bvFig. 478. CHAPTER XIII. PAKTIAL CAP AND PIN-BRIDGE METHODS. Dr. W. F.
