Mandibular resection template
View Patent ↗The present invention relates to a mandibular resection template including a central component which is prepared for attachment to a segment, for example a symphysis segment of a jawbone, such as a mandible or maxilla. At least two separating tool guide portions are present at the central component, a positioning aid being provided between the two or more separating tool guide portions in order to obtain a spatially correct orientation of the mandibular resection template with respect to the jawbone.
1. A mandibular resection template comprising: a central component which is prepared for attachment to a mandible or a maxilla, wherein at least two separating tool guide portions are present at the central component, and wherein a positioning aid is provided between the at least two separating tool guide portions in order to obtain a spatially correct orientation of the mandibular resection template with respect to the jawbone, wherein the central component is in the form of a frame having two horizontal webs, wherein on a front side and/or an upper side of at least one of the horizontal webs a center line marker is present.
2. The mandibular resection template according to claim 1 , wherein the positioning aid is configured as a notch and bead combination, notch, bore, prism, color marker, pin, screw or navigation positioning and/or as a positioning fin prepared for entering into contact with a portion of a mandibular bone.
3. The mandibular resection template according to claim 1 , wherein the positioning aid projects transversely from the central component.
4. The mandibular resection template according to claim 1 , wherein the two horizontal webs are connected to each other at their distal ends via the two separating tool guide portions configured as saw blade guide portions.
5. The mandibular resection template according to claim 4 , wherein the two separating tool guide portions and the two horizontal webs take a rectangular shape at least in a frontal projection.
6. The mandibular resection template according to claim 4 , wherein the two horizontal webs and the two separating tool guide portions are configured as a uniform and/or one-piece/integral and/or single-material component.
7. The mandibular resection template according to claim 1 , wherein either of the separating tool guide portions are in the form of a saw blade guide portion including a saw slit which is dimensioned to guide a bone separating tool.
8. The mandibular resection template according to claim 7 , wherein on both sides of the saw slit a bone separating tool contact face parallel thereto is formed.
9. The mandibular resection template according to claim 7 , wherein the saw slit protrudes completely through a material forming the same and, in addition, is configured in extension of its longitudinal extension to be open on one side or on two sides.
10. The mandibular resection template according to claim 9 , wherein the material forming the saw slit is block-shaped and/or one of the horizontal webs is in the form of a rectangular beam.
