We have developed a pure titanium mandibular head cap and applied it to the orthopedic site of the mandibular head in condyloplasty and arthroplasty.It is shaped to cover the mandibular head so that natural head form and structure can be restored when the cap is worn and stabilized.In addition, this mandibular head cap has tiny holes in its margin to accomodate the expected bone infiltration and has holes for screws at the parietolateral part so that it can be secured with bone-marrow screws that match the mandibular head and neck.The titanium cap comes in three sizes-large, medium, and small-that can be chosen according to the size of the mandibular head.<BR>The surgical procedure involving this titanium mandibular head cap follows condyloplasty. The coarse surfaces and bony lumps of the mandibular head are ground and eliminated with a surgical bur.Next, the cap is placed on the mandibular head to be stabilized diagnally or vertically with screws.In some cases, the articular tubercle is removed to facilitate forward movement of the mandibular head.<BR>In our practice, this procedure was indicated for temporomandibular arthrosis that was unresponsive to longterm conservative therapy (disc displacement without reduction), temporomandibular arthrosis deformans, and ankylosis of the temporomandibular joint.This paper primarily addresses, in summary, the procedures and application methods.
