Principles and practice of operative dentistry . Fig. 476. ©no H H. Weagant trephines. the Consolidated Dental Manufacturing Company, the inlay will receive afine polish, and, not being of porous material, it will show no tendency todiscoloration. This method is, however, open to one very serious objec-tion,—viz., the necessity of sacrificing a large amount of sound dentaltissue in order to give a circular outline to the walls of the cavity. Forthis reason, principally, the method has never been employed to any greatextent. A very beautiful and close joint may be made by this method ifthe joint is ground while the inlay is in situ. This may be accom-plished by cutting the inlay a size larger than the cavity which is toreceive it, and slightly tapering the section until the lower end will freelyenter the margins of the cavity. It may then be cemented to an enginemandrel, and ground into place by revolving it in the cavity, using pul-verized pumice moistened with water as the grinding medium, just as theplumber grinds the joint of a water-cock.
