Implant for reconstruction of temporomandibular joint. |
摘要 |
<p>A surgical TM joint implant is described having two parts: a first part (14) for covering or replacing the natural glenoid fossa of a natural TM joint, and a second part (30) for replacing the natural condylar head of the joint. The first part (14) includes a plate (13) having a fossa cavity (15) defined by a relatively deep concave portion (23) and an anteriorly located concavoplanar portion (23a). The second part (39) has a condylar head engaging the concavo-planar surface (23a) and establishing therewith a planar contact area (49) which minimizes the unit stress transmitted between the first and second parts, thereby providing for an even load distribution between their engaged planar surfaces.</p> |
