There are many problems in treating a mandibular fracture in an edentulous old patient. It is generally described that the use of osteoplate introduces better postoperative courses. AO osteosynthesis is one of the most suitable operation techniques for such a case. AO plate for mandibular fracture, however, is not formed well for fitting to the surface of the lower part of the mandible. A small 1/4 rolled plate for the finger fracture was selected as a material for the mandibular osteosynthesis. The bending test of the small 1/4 rolled plate was done at the five locations on the 10mmφ columnar polypropyrane bar (0°, 15°, 30°, 45°, 60° : as an angle of rag screw). The bars with the plate set by 0°-30°of rag screw presented no problem on strength.
