초록

Objectives : The titanium fixation system has been used in orthognathic surgery for fixation of bone segments
usually, but the biodegradable fixation system was developed and also being used. The strongest
point in the biodegradable system is that no extra operation should be needed to remove fixation materials.
In spite of this merit, oral & maxillofacial surgeons hesitate to use this system in fracture or orthognathic
surgery. In this study, as we got some clinical experiences, we'd like to report the result of clinical study
using the biodegradable fixation system in orthognathic surgery.
Patients and Methods : A total of 35 patients composed of 17 males and 18 females with 25 osteotomies
in maxilla and 34 osteotomies in mandible were fixated with the biodegradable fixation system(Inion CPS®).
We investigated methods of stabilization, fixation time, and complications on the basis of the method as
above.
Results : Four 2mm thick L shaped plates with 7 holes of which 1 hole was removed were fixed in maxilla
with six 2.0×7mm screws. Three 2.5×16~18mm screws were used to fix superior ramus area and one
mandibular angle area in mandible. It took about 27.4 minutes in maxilla, 25.3 minutes in mandible to
perform the fixation which took longer time than the titanium system(9.5 minutes in maxilla, 8 minutes in
mandible). Generally, there was no problem except 9 cases in which there were some complications.
Conclusions : In most cases, the biodegradable fixation system can be used without problem in usual
orthognathic surgery. But, this system is inferior to the titanium fixation one in some respects such as fixation
time, size, and physical property. Some supplementations for such weak points as aforementioned
should be needed for the universal use of biodegradable materials.
