ABSTRACT:
A frame has a pair of rails extending substantially in parallel relation. These rails are secured together at spaced points by cross webs and posts depend from these cross webs which support tooth-like portions secured together. The rails are arranged to be implanted respectively in grooves cut in the lower edge of the alveolar ridge of the upper jaw bone and in an area inwardly of the mouth of such edge such as in the palatine bone. The rails, posts and tooth-like portions are integrated into a one-piece unit and are all coated with porcelain to provide an attractive assembly as well as to provide structure that forms a physiological seal with mouth tissue.
