Abstract: Dental restoration. A glass filament mesh matrix has inner and outer faces, the inner face being adapted to be bonded to a natural tooth. An outer face of proper color is adapted to receive the final buildup of composite. The process of applying dental surface restoration matrix to the face of an existing natural tooth, comprising the following steps:a. Lubricating the surface of the natural tooth,b. Applying a glass filament matrix to the natural tooth, the matrix being impregnated with curable material,c. Curing the matrix,d. Removing the matrix from the natural tooth,e. Applying composite surface material of the proper color to the outer surface of the matrix,f. Replacing the matrix on the natural tooth with a bonding agent,g. Curing the matrix by either heat or light.

Abstract: Mastication force dampening dental implant has a cylindrical casing adapted to be implanted in a jawbone. A resilient insert is mounted in the casing and has a first shaftway. A nut is anchored in the insert coaxially with the first shaftway. A threaded shaft is mounted in the first shaftway, the shaft being threaded into the nut. The shaft has a second shaftway in its top portion. A head is fixedly connected to the first shaft at the top of the casing. A tooth or denture retention post is mounted on the head. The retention post is removably mounted in the top of the second shaftway.

Abstract: Process of making a post for inserting a false tooth in a vacant space between first and second good teeth having the following steps. Cut first and second small indentations in the sides of each first and second good tooth facing the vacant space. Make a plaster model of the first and second good teeth. Insert wax in the gum saddle between the two existing teeth of the model. Insert pontic having interior and exterior portions, one portion having a first wing and the other portion having a second wing. Apply wax to the first wing so that it extends into the first indentation. Apply wax to the second wing so that it extends into the second indentation. Remove the pontic portions separately with the wax attached to them with the saddle wax adhering to the lingual pontic portion. Cast each pontic portion separately by the lost wax process. Whereby the two castings may be inserted separately in the first and second indentations and fastened together.
