Abstract A dental procedure for providing a secure anchor in the mouth to which a denture can be attached utilizes a temporary post having a threaded shank carrying a cylindrical head. A natural tooth root is drilled and tapped to form a threaded hole in which the shank of the temporary post is received. An impression is taken of the face of the tooth root and the protruding head of the temporary post. The temporary post is removed and a cap, prepared from the impression and having a hole in it where the head projection occurred, is secured to the tooth root. A permanent post is then utilized which has its head in the form of a denture retainer atop a threaded shank. The threaded shank of the permanent post, after being coated with dental cement, is inserted through the hole in the cap and is screwed into the tooth root. With the shank fully inserted, the head of the post overlaps the hole in the cap. sits upon the cap to seal that hole, and aids in maintaining the cap in place on the tooth root.
A method for providing a secure anchor in the mouth to which a denture can be attached, comprising the steps of a. drilling and tapping a hole in a tooth root to receive a post having a shank with mating threads, b. screwing the threaded shank of a temporary post into the tapped hole so that the cylindrical head of the temporary post protrudes from the tooth root, c. making an impression of the face of the tooth root and the protruding head of the temporary post, d. from the impression, preparing a cap having a hole in it where the protruding head occurred, e. removing the temporary post, f. securing the cap to the face of the tooth root, and g. securing to the tooth root, through the hole in the cap, a permanent post having a threaded shank carrying atop it a denture retainer.
