Abstract: The disclosure is of a novel dental crown form and the method of its installation. The crown form of the invention is a tubular shell of a flexible polymeric resin corresponding generally to the configuration of a natural tooth. An embodiment of the crown form may be characterized in part by the means for fluid communication between the interior and the exterior of the shell, in the sidewall at points on the surface corresponding to the mesial and distal tooth surfaces. When applied to a tooth stump, filler is forced from the shell interior through the means to establish contact with adjacent teeth. The cured filler so expressed supports the crown form in position. The crown forms of the invention are also characterized by slits in specific positions of the shell sidewalls, having a uniform width. The slits permit the crown forms to flex open and closed along a hinge axis on the occlusal surface, thereby facilitating installation on a variety of tooth sizes.
