The advantages are:
(1) Stabilization of osteotomized bone fragment can be sure and complete.Relapse is less than with wire osteosynthesis.
(2) In mandibular osteotomy, owing to monocortical osteosynthesis, damage to neurovascular bundle and root of teeth is rare.Miniplate can be used in maxilla that has thin layer of cortical bone.
(3) Le Fort I osteotomy, zygomatic arch suspension wiring to stabilize bone fragments is unnecessary.
(4) The period of intermaxillary fixation is shorter than wire osteosynthesis. Opening of the mouth can be possible during operation and immediate postoperation.
Since 1982, we used miniplate in 63 cases of orthognathic surgical procedure with very satisfactory results.
