Claims
- 1. A dental oral stimulator comprising a mounting means with a concave depression to provide a bearing surface, said mounting means being supportable at an ergonomically appropriate position for dental manipulation, an occipital simulator in the form of a hollow open topped semispherical bowl having an outer surface of the bowl generated about a simulated occipito-atlantal joint, said bowl being supported in said mounting means with the bearing surface of the mounting means complementary to the outer surface of said bowl, position control means to allow controlled relative movement between the bearing surface of said mounting means and said bowl to simulate a range of anatomical movements useful in dental treatment by a human skull about its occipito-atlantal joint, a transverse jaw support plate removably mounted within said bowl, said plate passing through the axis of the simulated occipito-atlantal joint, training jaws removably supported on said jaw support plate with said plate and jaws being located so that movement of said bowl in said bearing surface of the mounting means controlled by said position control means causes said training jaws to move to simulate movement of jaws in a skull about the occipito-atlantal joint.
- 2. A dental oral simulator comprising a support arm attachable to a support member, a concave dish fixed to the end of said arm with a concave depression of said concave dish providing a bearing surface, said support arm and concave dish being supportable at an ergonomically appropriate position for dental manipulation, gate means in the concave dish provided by a pattern of interconnected slots to accommodate movement of substantially 37.degree. and 25.degree. forward and 12.degree. back and 15.degree. to 20.degree. on either side, a complementary occipital simulator provided as a hollow open topped semispherical bowl having an outer surface of the bowl generated about a simulated occipito-atlantal joint when said outer surface of said bowl is supported in said concave dish with a position control member to protrude through said gate means to allow controlled relative movement to simulate movement in the sagittal plane between the concave dish and said bowl similar to a range of anatomical movements useful in dental treatment by a human skull about its occipito-atlantal joint, holding means operable to allow the bowl to be held in any one of a number of positions for dental training predetermined by the location of the position control member in the gate means to retain said bowl in a selected position, a jaw support plate removably mounted within the bowl, said plate passing through the axis of the simulated occipito-atlantal joint, training jaws removably supported on said jaw support plate with said plate and jaws being located so that movement of said bowl in the bearing surfaces of the concave dish controlled by the gate means, position control member and position holding means causes the training jaws to move to simulate movement of the jaws in a skull about the occipito-atlantal joint.
- 3. A dental oral simulator as claimed in claim 2 wherein the gate means has three parallel grooves with the central groove on the central axis of the dish and the other grooves symmetrically positioned about the central groove and with a transverse groove connecting the three parallel grooves.
- 4. A dental oral simulator as claimed in claim 3 wherein the transverse movement through said gate means is provided at approximately 8 degrees from the rearward position end of the groove.
