Abstract: The aim of the current
study is to assess the efficiency of poly-L- lactic acid (PLLA) plating system
for LeFort I maxillary advancement stability in combination with bilateral
sagittal split ramus osteotomy (BSSRO). The current study was conducted on 16
patients with age range 20-33 years old with skeletal class III. After
preoperative workup, all patients were submitted for Le Fort I maxillary
advancement and mandibular setback by BSSRO. The patients were divided into 2
equal groups. Titanium miniplates and monocortical screws were utilized for fixation
in group I while, PLLA plating system was used for group II. Statistical
significant differences were identified between the two groups in S-ANS
perpendicular to SN, S-PNS perpendicular to SN, S-PNS parallel to SN and S-A
point parallel to SN. Moreover, no statistical significant differences were
identified in S-ANS parallel to SN and S- A point parallel to SN. In
conclusion, these results suggested a slight tendency for vertical impaction
after Le fort I osteotomy in group II, although difference in time course
changes were not clinically apparent and normal occlusion was established in
all patient.
