ABSTRACT OF THE DISCLOSURE A self-threading dental anchor including a proximal head end providing a manipulating end section for permitting the coupling thereof to a cooperating driving tool, and a threaded anchoring portion extending from the proximal head end. The anchoring portion threads are in the range of 60-100 threads per inch, preferably 84 threads per inch with standard threads and 96 threads per inch with a buttress type thread, to provide for fast insertion with minimum torque. The anchoring portion has an elongated distal pilot end portion in the axial direction approximately equal to the thread pitch of approximately 0.010 to 0.012 inches. A second threaded anchoring portion may be connected to the distal pilot end portion of the first mentioned anchoring portion to provide a frangible reduced thickness portion therebetween, which is readily visible. Preferably, each thread has a height of approximately 0.0020 to 0.0025 inches, Modified embodiments of the dental anchor are pro- vided with stop members spaced preferably midway along the length of each anchoring portion to limit the depth of in- sertion thereof into a channel which extends into a tooth understructure. The stop members can be formed by providing an unthreaded portion, by deforming, heading, offsetting, stamping, splaying, and the like. -36-
