Abstract
Mandibular prosthesis (10) for a mandibular side of a temporomandibular joint, mandibular (200) and cranial cutting guide, cranial prosthesis (50) for the temporomandibular joint, temporomandibular joint (100) and set, and procedure for inserting a temporomandibular joint (100).
Claims25
A mandibular prosthesis for a mandibular side of a temporomandibular joint, comprising:
- a head part to replace the condylar head, and
- an attachment plate for attachment to the mandible wherein the attachment plate comprises:
- a lateral portion that has been formed and is intended for abutting the lateral side of the ramus, and
- an upper portion, forming one unity with the lateral portion,
- wherein,
- the upper portion comprises at its underside a plane support surface for resting on a flat cutting surface provided at the upper side of the ramus after removing the condylar head, the head part comprises a mounting section for mounting a joint head, wherein the mounting section is forming one unity with upper portion.
(canceled)
A mandibular cutting guide for arrangement at the ramus and at least partially around the condylar process, comprising at least
- a lateral wall section for abutment against the outside of the ramus, and
- a guide surface for guiding a cutting instrument when cutting off the condylar head along the guide surface, wherein the guide surface provides a cutting-start-region and a cutting-end-region, and wherein a cutting stopper is provided at the distal end of the cutting-end-region.

A cranial cutting guide for arrangement at the zygomatic arch in the region of the temporomandibular joint comprising at least
- a lateral wall section for abutment against the outside of the zygomatic arc, and
- a planar guide surface for guiding a cutting instrument when cutting off parts of the zygomatic arc, wherein the guide surface provides a cutting-start-region and a cutting-end-region, and wherein a cutting stopper is provided at the distal end of the cutting-end-region.
A one piece cutting guide with a first part comprising a cranial cutting guide for arrangement at the zygomatic arch in the region of the temporomandibular joint comprising at least a lateral wall section for abutment against the outside of the zygomatic arc, and a planar guide surface for guiding a cutting instrument when cutting off parts of the zygomatic arc and a second part comprising a mandibular cutting guide for arrangement at the ramus and at least partially around the condylar process, comprising at least a lateral wall section for abutment against the outside of the ramus, and a guide surface for guiding a cutting instrument when cutting off the condylar head along the guide surface.
(canceled)
A cranial prosthesis for a cranial side of a temporomandibular joint, comprising
- a lateral portion that has been formed and is intended for abutting the lateral side of zygomatic bone of the cranium,
- a main body, forming one unity with the lateral portion, comprising
- an upper portion that has been formed and is intended for abutting the fossa,
- a lower portion with a joint pan that has been formed and is intended for receiving a joint head of a prosthesis for the mandibular side of the temporomandibular joint.
