Background

The normal tooth abutment has a certain degree of convexity, which can not only make the adjacent teeth closely arranged to form a correct abutment, also has guiding effect on food during chewing, and can maintain gingival tension to prevent food from being jammed. When the clinical tooth adjacent surface hole is filled, the forming sheet is needed to replace the missing tooth side wall, and the gingival clearance is put into the wedge to enable the forming sheet to be tightly attached to the tooth surface, so that the material is convenient to be pressed and formed in a sealing manner, and the normal adjacent surface shape of the tooth is recovered.

The existing formed sheet is usually small and thin, and cannot penetrate into subgingival and be fixed when encountering deeper subgingival defects, so that the metal bean cotyledon formed sheet is applied and extends subgingivally on the basis of the conventional formed sheet, but the bean cotyledon formed sheet is softer and is not easy to fix when in use. Clinically, a mixing knife is sometimes used for molding, the mixing knife is high in hardness, flat in appearance, easy to place and easy to hold with a long handle, but the mixing knife does not belong to a special tooth filling tool, so that a molding device capable of being conveniently held and rapidly fixing a molding piece is needed.
