Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
134 words
A maxillofacial bone clamp for attachment to a maxillofacial bone, comprising: means for engaging the maxillofacial bone, the means for engaging comprising arch with a facial wing and a posterior wing for conforming to a facial cortical surface and an antifacial cortical surface, respectively, of the maxillofacial bone or clamping the maxillofacial bone between the facial wind and the posterior wing; a stabilizing ridge extending from a concave side of the arch between the facial wind and the posterior wing and connected to a concave portion of at least one of the facial wing and the posterior wing for strengthening the bone clamp and for antirotationally engaging a crestal groove in the maxillofacial bone; and at least one threaded fastener for engaging the engaging means and attaching the engaging means to the maxillofacial bone.
Claim 2
Dependent Claim
134 words
A maxillofacial bone clamp for attachment to a maxillofacial bone, comprising: means for engaging the maxillofacial bone, the means for engaging comprising arch with a facial wing and a posterior wing for conforming to a facial cortical surface and an antifacial cortical surface, respectively, of the maxillofacial bone or clamping the maxillofacial bone between the facial wind and the posterior wing; a stabilizing ridge extending from a concave side of the arch between the facial wind and the posterior wing and connected to a concave portion of at least one of the facial wing and the posterior wing for strengthening the bone clamp and for antirotationally engaging a crestal groove in the maxillofacial bone; and at least one threaded fastener for engaging the engaging means and attaching the engaging means to the maxillofacial bone.
