Clinical Trial Summary
The purpose of this study is to evaluate the reliability of using mandibular osteosynthesis a
2.3mm reconstruction bone plate in the maintenance of the space, contour, and mandibular bone
preservation during marginal mandibular resection.
Description:
This prospective study included 16 patients (n=16) suffering from presence of mandibular
central benign lesions indicated for marginal mandibular resection.
Patient history included personal data (name, age, sex, and occupation), date of lesion
discovery, mode of growth (rapid or slow), and symptoms (e.g. pain and/or ipsilateral
paresthesia of the lower lip).
Clinical examination included the site and extent of mandibular bony expansion and covering
soft tissues (normal, ulcerated from indentation of opposing teeth, or scarred due to
previous incisional biopsy).
Radiographical examination involved orthopantomography (OPG) and axial and coronal computed
tomography (CT) scans to assess the lesion extensions.
All patients are operated under general anesthesia which was induced by intravenous access.
Intubation is routinely performed in nasoendotracheal fashion.
Intraoral buccal and lingual incisions 2-3 mm away from the free gingival margins are carried
out around the teeth to be included in the resection.
The plastic template is adapted to the buccal cortex of the mandible to aid in the final
adaptation of a 2.3 mm reconstruction bone plate (Antonhib, Germany). The osteotomy lines are
marked using a long shank surgical tapered fissure bur. a 2.3 mm reconstruction bone plate is
then fit in place and fixed to both the proximal and distal segments then removed. The
osteotomies completed and the resected segment is removed, and the reconstruction plate is
then replaced by the aid of screw holes in both the proximal and distal segments. The
intraoral wound is carefully closed in double layers using a combination of interrupted and
horizontal mattress resorbable 3/0 sutures.
post operative follow up clinically regarding soft tissue healing, pain, infection, and plate
exposure or plate fracture. Radiographically, Panoramic radiographs are taken immediately and
axial and coronal computed tomography at six months post-operatively.
