Abstract
Abstract Using a highly flowable silicone putty which can be combined with catalysts to set, dentures can be repaired and modified by flowing the putty onto the dentures, allowing it to set while in intimate contact therewith, removing the dentures from the set putty for effecting changes, and subsequently reinserting the dentures in the set putty to effect any necessary changes, modifications or repairs. Prior art practices often used dental stone which had to be chipped away from the dentures when effecting repair or modification. Methods of repairing and modifying dentures herein described involve the steps of forming a flowable mass of moldable, settable silicone putty which has been mixed with a catalyst to cause it to progressively set, molding said putty to a denture surface and allowing it to set while in intimate contact with said denture, thereafter extracting said denture from said putty by flexing the latter, effecting the necessary changes to said denture and subsequently replacing said denture in said set putty by flexing the latter to obtain the proper positioning thereof for effecting any necessary changes and repairs.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
136 words
A method of repairing dentures comprising the steps of: (1) gluing a broken denture together along its break to restore it to its original integral configuration; (2) mixing a moldable, settable putty with a catalyst, said putty being a silicone type, (3) gently forcing a portion of said putty under pressure onto a surface of said glued broken denture so it conforms to and extends across said break, thereafter allowing said putty to set-up, (4) removing said broken denture from the resulting impression in said putty, (5) separating said denture along said break and removing denture material on either side thereof; (6) replacing said denture in the impression in said putty; and (7) subsequently adding settable plastic material to the area of said break to bond pieces of said denture together as a unitary, serviceable denture.

Claim 3
Independent Claim
183 words
A method of relining denture which contain a wash material on the roof pallate surface comprising the steps of: (1) mixing a moldable settable putty with a catalyst, said putty being a silicone type; (2) gently forcing a portion of said putty under pressure onto the surface of the wash material disposed on a denture with teeth in a sufficient amount to cover it with at least a layer of 1/4 of an inch, and allowing said putty to set-up thereafter; (3) placing said putty and denture in a dowelled two-part jig and setting the teeth of the denture and said putty with plaster-like material respectively in opposite parts of said jig and allowing said plaster-like material to harden, (4) subsequently separating said jig, (5) removing said wash material from the surface of said denture and (6) reassembling said jig with a settable liquid plastic material between said denture and said putty in sufficient amount to fill the cavity left by removal of said wash material and allowing said plastic material to set-up and bond to said denture thereby effecting a reline thereof.
