Abstract
A two stage intra-oral protective system is provided for protecting teeth, lips, and jaw from injury and/or for supporting the temporomandibular joint (TMJ) in a relatively fixed (stable) position thereby stabilizing the TMJ during head contact activity and/or permit the components of a TMJ disorder to be realigned for proper healing. Stage one is a mandibular orthodontic repositioning appliance and stage two is a mouth guard providing maxillary and mandibular teeth seats whereby the two stages harmoniously work together for protection and/or healing of the TMJ.
