Posterior Bite Plane

Same concept as an anterior biteplate except it comes between upper and lower posterior teeth, causing an amount of space to be available between the upper and lower anterior teeth. This in turn would allow the anterior teeth to erupt.

A posterior biteplate is used to correct an anterior open bite It is often used with other appliances such as an expander. It does so by allowing the anterior teeth to erupt (extrude) while preventing the posterior teeth from erupting (some relative intrusion of the posterior teeth).
May also be used along with fixed appliances to allow the trapped tooth to come into occlusion.
