Abstract: A dental implant system including an implant having an incisal portion for insertion into a alveolar receptor site formed in the jawbone to receive the implant, a collar having a beveled shape extending superiorly from the incisal portion with a smooth polished surface, a threadless cavity extending from the occlusal end of the implant partially into said embedded incisal portion with the cavity having a recessed groove adjacent the proximal end of the incisal portion, a removable healing cap adapted to be placed into the threadless cavity of said implant with said healing cap having a resilient shoulder projecting therefrom to engage said groove for forming a sealed interlock during an extended healing period and a single post abutment member for insertion into the threadless cavity of the implant after removal of the healing cap.

Abstract: An osteoblastic stimulated implant contacting bone in the body in which is provided a self contained unit positioned between the base of the implant and a cap member, a chamber positioned between the cap member and the base, containing a current generating unit, which can be a piezo electric element, a battery, a coil and magnet, or the like, wherein the movement of the cap towards the base will cause a flow of current into the base member.

Abstract: A porcelain denture tooth for attachment to the denture plastic base, mounted to the gums, made with a unitary thinwalled metal embedded support, U-shaped in cross-section, embedded in the denture tooth body, with portions of the U-shaped metal retainer extending outside the tooth body to form ahead portion for attachment to the denture base.

Abstract: A dental appliance for maintaining axis parallelism of dental dowel pins when positioning replicas of teeth taken from impressions in a model of the mouth, which employs a plate, connected pivoting links, or a rail, having a plurality of apertured seats for mounting the dowel pins therein in positions conforming to the configurations of the teeth and for maintaining axis parallelism of the dowel pins, said apertured seats being permanently mounted to each other in predetermined transverse positions, to provide a simplified structure for locating the mounted dowel pins with respect to the impressions of the teeth.
