The treatment of maxillo-facial fractures requires
a special understandinG of both orthopedic and dental
principles. Apart from a meticulous examination, the
most important factor in this treatment is the anatomically
correct reduction and rigid fixation of the fracture
according to the pre-existing occlusion.(l)
In recent years, bone plating system in connection
with surgery of the extremities have been developed to
fulfil a completely functionally stable connection of
the fragments VJhichmust remain firm for the period required
for healing of the fracture and the restoration
and maintenance of correct occlusion in cases with standing
full or partial dentition without disadvantages of
employing intermaxillary fixation. The compression plate
system solves one of the two basic problems namely stable
redu~tion and fixation and it is far superior to all other
methods for this purpose. (2)
The primary goals of treatment of mandibular fractlITeSare
to re-establish proper occlusal relationship,
adequate function, and esthetic ho..rmony.
1.
The main surgical objective is to provide sufficient
immobilization of the fragments to allow normal bony
heal~ngto occur. This goal is most often achieved by
closed reduction using maxillo-mandibular fixation (MMF)
However, oral and maxillofacial surgeons and others invalved
in the treatment of mandibular fractures have long
been aware of complicating situations that can limit or
precludethe use of N~F. As a result, a number of techniques
have evolved to provide internal fixation so as to
minimize or eliminate the need for MMF and to more precisely
align the bony fragments.(3,J+,5,6)
A prolonged period of immobilization of a fractured
mandible b;ymaxillo-mandibular fixation is not without
complications. In addition to the discomf'ort and inconvenience
experienced by the patient, it can cause postoperative
embarrassment of the air way, (7)disrupt the
normal intake of food, and offer a serious problem in the
treatment of a mentally deficient, an epileptic, an uncooperative,
or an unconscious patient. If immobilized
for prolonged periods of time, ankylosis may. develop in
patients with fractured mandibles who have had sufficient
trauma to the temporomandibular joint with resultant hemarthrosis.(
8) Because of these complicating situations,
a new technique is presented to eliminate or considerably
decrease this period of maxillo-mandibular fixation.
This involvesimmobilization of fractured mandibles after
open reduction with the use of compression screw plate
system.(9) It offers a more rigid fixation and better
resists muscular forces that tend to displace such fractures,
there is little or no need for maxillo-mandibular
fixation (Zero to two weeks). The patient is able to
effect jaw function while the fracture heals.(IO)
Compression fixation of fractures and osteotomies
has gained wide acceptance in recent years, Danis(ll)was
probably the first to design a rigid longitudinal compression
system using a plate screwed to the bone cortex
and compressed by a device incorporated in the plate.
Using this technique, Danis was successful in securing
radiological " Primary bone healing " in fractures of
the forearm bones and ti bia. (12)
