Abstract
A temporo-mandibular joint prosthesis comprising: a first part for attaching to a temporal bone; a second part for attaching to a mandible bone; and a mechanism linking the first part and the second part. The mechanism defines a range of motion of the first part relative to the second part for when the first and second parts are attached to a temporal bone and a mandible bone, respectively. The mechanism includes a rotary joint providing a rotational range of motion of the first part relative to the second part; and a first slider joint providing a first translational range of motion of the first part relative to the second part.

A temporo-mandibular joint prosthesis comprising:
- a first part for attaching to a temporal bone;
- a second part for attaching to a mandible bone;
- and
- a mechanism linking the first part and the second part, the mechanism defining a range of motion of the first part relative to the second part for when the first and second parts are attached to the temporal bone and the mandible bone, respectively, the mechanism including:
- a rotary joint providing a rotational range of motion of the first part relative to the second part;
- a first slider joint providing a first translational range of motion of the first part relative to the second part;
- and
- a second slider joint providing a second translational range of motion of the first part relative to the second part,
- the rotary joint comprising a first element and a second element, a surface of the first element rotatably interfacing with a surface of the second element, wherein the first part is linked to the first element by the first slider joint.
