| 181 | Breakaway devices for stabilizing dental casts and method of use | US426771 | 1999-10-26 | US6142779A | 2000-11-07 | Sharon Crane Siegel; Ronald Bruce Gunderson |
| A device for efficiently, accurately and consistently securing dental casts while an articulator is attached thereto includes a spine connecting a first stabilizing pad at one end to a second stabilizing pad at an opposite end. The device includes a breakaway feature which allows a connection between the casts to be broken with manual force. The first stabilizing pad and the second stabilizing pad are secured to maxillary and mandibular casts with an adhesive or the like, or by other methods such as magnets, to create a rigid connection between the accurately related maxillary and mandibular casts. The breakaway feature allows a technician to easily break the connection between the maxillary and mandibular casts with manual force after the articulator has been attached to the casts. | ||||||
| 182 | Auxiliary tool for occluding apparatus and method of mounting dentiform model on occluding apparatus | US134996 | 1998-08-17 | US5967776A | 1999-10-19 | Han-Joon Kim |
| An occluded state and an opened state are reproduced on an occluding apparatus by a pair of upper and lower dentiform models using a bite at the time of occlusion and a bite at the time of opening which are extracted from a patient. For the reproduction, a D plate (Dual Mounting Plate) 9 is used. When the D plate 9 is used, it is possible to produce a C block which is integrated with an upper jaw teeth mode 4 by gypsum and an S1 block (or an S2 block) for a spacer which is mounted between the C block and an upper mounting plate 11 (12). The occluded state and the opened state can be reproduced using the dentiform models by replacing the S1 block and the S2 block with each other. | ||||||
| 183 | Dental model articulator | US916533 | 1997-08-21 | US5957688A | 1999-09-28 | Edwin T. Van Valey |
| A dental model articulator includes two hinge-jointed arms, each arm having segments connected at a hinge joint having mating elements, one integral to each segment of an arm. One element includes two cymbals that are coaxial on a major hinge axis and concave facing which resiliently capture between them a node of the mating element on the other segment which has the form of opposed, outwardly facing convexities. Multiaxial motion between the segments of each arm is accommodated by the rotation of the convexities of the node within detents at the apices of the cymbals. The extremities of each arm terminate in cylindrical rod-like elements that are parallel to the major hinge axis. The rods engage with transverse, cylindrical channels either cut-in, molded-in or affixed to the models. With the models positioned in centric occlusal relationship and the arms adjacently positioned and engaged, the four rods are adhesively fixed in the channels. Once fixed, the two hinge joints together define a single hinge axis posterior and interjacent to the models. Further, each hinge joint can allow the node elements to release from the axis detents and slide between the cymbals to permit protrusive and lateral masticatory motions between the dental models. | ||||||
