| titleOfInvention | Dental clutch fabrication |
| abstract | An improvement in the dental clutch fabrication means shown in U.S. Pat. No. 3,508,333 is described herein. The improvement permits use of but a single set of clutch support forks for endentulous and dentulous patients and provides preformed bearing pin guide means for greater precision of operation. The dental clutches, which are intaglio castings of the teeth, are formed on support forks that are secured in precise relationship to each other by jig means which has a separation plate to separate the clutches as they are formed. The clutches are preferably cast in the patient''s mouth, directly on the teeth. The improved support forks described herein are combined with plates having bearing pin guide surfaces which have a preformed contour so that no difficulties are encountered in the forming of this guide surface. Two types of bearing surfaces are provided; a substantially flat planar surface for endentulous patients and a dished surface, preferably having a particular shape to encourage purely lateral and protrusive movements, for dentulous patients. The plates have means to index their position to the fork when casting the clutches and can be attached or unattached to the forks. The plates are preferably supported from the forks with attachment means which permits their removal so that they can be supplied in pairs and the undesired bearing surface can be removed from one of the forks which can then be used for forming the mandibular clutch, while the fork bearing the desired bearing surface is used for the maxillary clutch. |
