ABSTRACT
Currently, fixation with "absorbable plates and screws" is widely used for the treatment of facial bone fracture. But it is carefully used for mandible fracture, because it needs much stronger skeletal stability caused by deviation in part of fracture. And there are some complications by using it. We need "absorbable plates and screws" depending on the case of fracture site of mandible and combined fracture. And it was classified favorable or unfavorable fracture according to the aspect of fracture site. In favorable fracture without deviation of symphysis, only "one absorbable plate and screws" has been used, and in unfavorable fracture, we used "two absorbable plates and screws". In the cases of body and angle fracture, "two absorbable plates and screws" have been used because there is more underneath load in body and angle fracture than in symphysis fracture. As this way, we basically used Biosorb FX(R) 2.0 system and applied 21 patients in 34 cases. Finally, we got enough skeletal stability in mandibular fracture and there were not any complications such as malocclusion, ununion and late tissue response. So we report these results along with document consideration.
