Arch Bar versus Titanium Mini-Plate Fixation in Anterior Segmental Osteotomy /
Orthognathic Surgery (Cohort Clinical Study)

Aims and objectives: To compare the efficacy and outcome of arch bar versus plating fixation on the integrity of the
osteomised segment.
Materials And Methods: The study involved a total of 43 patients (86 jaws) undergoing upper (Wassmund) and
lower (Kole) anterior segmental osteotomy from (2006-2013) in the Maxillofacial Department in Al-Salam
Teaching Hospital/Mosul. The sample was divided into two groups, group A (43 jaws), the osteotomized segments
fixed with the arch bar, while group B (43 jaws) fixed with mini-plates. The clinical evaluation includes the following
criteria: pain, swelling, bleeding, wound healing, oral hygiene ,integrity of stabilization, relapse rate and duration
of operation.
Results: Clinical parameters as pain, swelling, and wound healing show no significant differences between groups;
on the contrary, the bleeding scale and gingival health scale show very high significant differences in p-value. The
integrity of stabilization immediately in operation reveals stable surgical correction in both groups. Still, one jaw
from each group develops significant mobility (grade II) that necessitate the use of additional local types of fixation.
Duration of operation: this manure could be operator skill dependent, in that most cases managed clinically in
teaching hospitals necessitating some delayed time in operative work, but as a mean time overall patients in group
A was 90 minutes, while in group B was 77 minutes.
Conclusions: According to this study, we prefer to use an arch bar rather than manipulates for fixation of anterior
segmental osteotomies.
