The OraStretch press is a jaw motion rehab system. It is a user operated device that opens jaw to stretch the oro-facial tissues and mobilize the temporomandibular joint (TMJ). It is used primarily to prevent and treat trismus and scarring or fibrosis from radiation therapy, surgery, and trauma. On average, 54% of oral and 62-85% of nasal cancer patients will experience trismus from surgical and radiation treatments. The system is also used to treat TMJ disorder and dysfunction. Trismus or jaw hypomobility is the inability to open the mouth.
