Orthodontic and surgical technical advances in recent years have resulted in treatment opportunities for a whole range of craniofacial skeletal disorders either in the adolescent or adult patient.
In the growing child these can include myofunctional orthodontic appliance therapy or distraction osteogenesis procedures, whilst
in the adult the mainstay approach revolves around orthognathic surgery.

The literature agrees that for a change in craniofacial morphology to remain stable, the muscles acting upon the facial skeleton
must be capable of adaptation in their structure and, therefore, their function. Failure of the muscles to adapt to the change in
their length or orientation will place undesirable forces on the muscle attachments leading to potential instability of the skeleton.
Adaptation can occur through various processes including those within the neuromuscular feedback mechanism, through changes
within muscle structure or through altered muscle physiology, and through changes at the muscle/bone interface.

Evaluation of Pressure Changes in Orthognathic Surgery using Pressurex® in 3 Years of Follow-up

Despite its importance, the measurement of pressure in orthognathic surgery often receives little attention. Pressurex® (SPL – Sensor Products LLC, USA) is one of a few pressureindicating sensor films that reveals pressure distribution and magnitude between any two contacting, mating or impacting surfaces, and is currently viewed as a golden standard for that purpose. This study was designed to test Pressurex® in orthognathic surgery.
