Gelb Appliance

A Gelb appliance is a device that sits on the posteriors and repositions the mandible to control the positioning of the jaw and avoid excess force. In addition to controlling the positioning of the jaw, it also maintains the mandible arch shape. It brings the condyle into a more anterior, resulting in an inferior position in the fossa, and increases the vertical opening, which can relieve pain.

Appliance overview

The Gelb splint provides complete protection for the posterior and allows for more tongue space by cutting away the anterior coverage which is beneficial for patients who snore, have sleep apnea, and/or have a large tongue. However, the appliance does not retrain your patients’ muscles to actually prevent the root cause of their TMJ.
