Abstract A mounting plate is formed from plastic and with a first one of its planar surfaces substantially flat and otherwise formed to be affixed to a dental model. A connecting rib, formed to extend out from the other planar surface of the mounting plate, and along its entire length, has a modified "T" shaped configuration with a vertical leg extending up from the planar surface and a cross-arm extending out to each side of the leg so as to form a groove to each side of the vertical leg between the planar surface of the plate and the opposed surface of the cross-arm. A slot is formed through the central rib of each articulator with a shoulder extending from each wall of the slot into the slot but so as to leave a narrow passage sized to receive the vertical leg of the modified "T" shaped rib. The grooves formed between the cross-arm of the rib and the plate surface, in turn, receive the shoulders that extend into the slots, all so as to tightly receive the connecting rib of the mounting plate and firmly but removably secure the mounting plate, and any dental mold affixed thereto to one of the bows of the dental articulator.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
185 words
A dental articulator, comprising: (a) a lower jaw; (b) an upper jaw pivotally mounted to said lower jaw; (c) a lower member carried by said lower jaw; (d) an upper member carried by said upper jaw; (e) at least one slot formed in said lower member so as to extend inwardly from an edge thereof and including at least one slot formed in said upper member so as to extend inwardly from an edge thereof, wherein said slots in said upper and lower members are each formed with shoulders extending from the sides thereof into the slot but so as to be spaced from each other to leave a slit therebetween; and (f) a dental model mounting plate for each member being formed with a rib and wherein the dental model mounting plate rib is formed as a modified "T" with the vertical leg thereof extending up from a planar surface of the dental model mounting plate and having a cross arm extending to each side of the vertical leg, said rib and slot being sized to releasably mount the mounting plate to the articulator.
Claim 2
Dependent Claim
185 words
A dental articulator, comprising: (a) a lower jaw; (b) an upper jaw pivotally mounted to said lower jaw; (c) a lower member carried by said lower jaw; (d) an upper member carried by said upper jaw; (e) at least one slot formed in said lower member so as to extend inwardly from an edge thereof and including at least one slot formed in said upper member so as to extend inwardly from an edge thereof, wherein said slots in said upper and lower members are each formed with shoulders extending from the sides thereof into the slot but so as to be spaced from each other to leave a slit therebetween; and (f) a dental model mounting plate for each member being formed with a rib and wherein the dental model mounting plate rib is formed as a modified "T" with the vertical leg thereof extending up from a planar surface of the dental model mounting plate and having a cross arm extending to each side of the vertical leg, said rib and slot being sized to releasably mount the mounting plate to the articulator.
Claim 3
Dependent Claim
47 words
The dental articulator of claim 1, wherein the cross arm forms a pair of grooves between itself and the planar surface of the mounting plate; and wherein the grooves are sized to accommodate and receive said shoulders formed in said slots of said upper and lower members.
Claim 4
Dependent Claim
14 words
The dental articulator of claim 1, wherein the mounting plate is formed from plastic.
Claim 5
Dependent Claim
11 words
The dental articulator of claim 3, wherein the plastic is vinyl.
