Patient was first sent in March of 1992 with a large multilocular lesion of the left mandible diagnosed as an ameloblastoma. | |
  |
The tumor was excised and mandibular position maintained with a bone plate. In July 1992 mandibular continuity was restored with a bone graft from the iliac crest. | |
  |
Following 6 months of healing 4 ITI implants were placed into the graft in February 1993. | |
     |
Prosthesis fabrication began in July 1993 (fig 6) and was completed in October (fig 7 thru 11). The distance from implant level to occlusal plane made it necessary to use custom designed "Extender System" components (also called Bone Graft components" of 8mm in length. The prosthesis on top of the abutments added another 20mm to the occlusal level. This creates an extremely unfavorable lever arm situation that must be dealt with. Occlusion was designed to be as light as possible with no excursive contacts. The fact that the patient had no feeling in the tissues buccal to the prosthesis made her tend to chew exclusevely on the opposite side thereby reducing the potential load on the implant prosthesis. The hollow screw implants used would probably today be solid screws instead. | |
 |
The restoration has been in place now for 5 years without need of adjustment of any kind. A most satisfactory solution to a very difficult problem. | |
