Abstract
Abstract This disclosure describes a composition of matter made up of approximately 50 percent by weight calcium carbonate, approximately 50 percent by weight polymethylmethacrylate plus sufficient methyl methacrylate monomer to form a dough. This filled acrylic resin composition is useful in dental splinting methods. Also disclosed is a dental splinting method employing this filled acrylic resin composition in combination with interproximal pins and an elastic connector.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
63 words
A process of dental splinting comprising: a. placing preformed, noncorroding metallic interproximal pins between selected adjacent teeth; b. applying in contact with the teeth and pins a dough-like filled acrylic resin, leaving the ends of the pins uncovered; c. allowing the filled acrylic resin to cure and harden; and d. interconnecting the ends of the pins with at least one elastic connecting means.
Claim 2
Dependent Claim
32 words
The process of claim 2 wherein said dough-like filled acrylic resin comprises substantially one-half by weight calcium carbonate, substantially one-half by weight polymethylmethacrylate and sufficient methyl methacrylate to form a dough-like substance.
Claim 3
Dependent Claim
83 words
A construction for dental splinting comprising: a. interproximal pins situated between selected adjacent teeth in the upper jaw and in the lower jaw; b. a cured, filled acrylic resin composition located longitudinally alongside the teeth and in contact with them, wherein part of the exterior end portions of the pins extend outward from the surface of the acrylic resin material; and c. at least one elastic connector engaging exterior end portions of the upper pins and exterior end portions of the lower pins.
Claim 4
Dependent Claim
23 words
The construction of claim 1 wherein the elastic connector engages exterior end portions of upper and lower pins which are relatively angularly displaced.
Claim 5
Dependent Claim
50 words
A noncorroding metallic bifurcated interproximal pin for use in dental splinting comprising: a. an elongated portion having a blunt tip; and b. a bifurcated portion connected to said elongated portion, wherein said bifurcated portion has a generally V-shaped configuration and the furcated portions each terminate in an outwardly curving portion.
