Posterior Shim System

​

A bilateral posterior stabilization device results in parallel maxillary and mandibular planes.   Molar stabilization prevents or completely eliminates slant, thus maximizing oropharyngeal airway opening.

​

An anterior stabilized jaw registration device results in slant, an acute angle between the dental arches, narrower at the posterior than anterior. Slant in the jaw registration for a sleep apnea patient assumes a suboptimal treatment position that diminishes airway opening.
