Abstract
Dental anchoring means of the kind including a threaded pin which is located in a hole in a tooth. Before insertion into the hole, the pin is integral with a shank through a neck which allows the pin to break off from the shank after insertion. The pin and shank are located in a longitudinal open-ended bore in a connecting member which is arranged to be secured in a dental handpiece. The pin and shank are fixed in the bore by forming an enlarged head on the shank which is a force fit in the bore. This locks the pin and shank securely in the bore during use and the connecting member can be of different material from the shank and pin.
