Many of us use bite splint therapy as a way to deprogram muscles, confirm a seated joint position, protect teeth and restorations from wear, treat TMD symptoms and engage patients.  Most of us fabricate these ourselves in a conventional manner with alginate impressions, analog bite records and cold cure acrylic.  Some utilize a lab to fabricate their splints on mounted casts with processed acrylic. Today there is a digital solution to splint fabrication.  The advantages are amazing fits requiring no reline and only minimal adjustments.  The acrylic is very dense with no voids and extremely polishable.
