An interocclusal sports prophylaxis includes a core having an arch shaped occlusal plate with upwardly extending buccal and lingual walls. A labial force dispersal shield and molar framing braces extend downwardly from the plate at incisor and lingual zones of the plate. The occlusal plate is thickened at the molar and incisor zones so that breathing spaces are provided between mandibular occlusal surfaces not registered with the zones and a mandibular face of the plate. A shock absorption dentition encasement is molded over the upper surface of the core and also covers the molar and incisor zones. The prophylaxis is heated in water, seated in the mouth and then biting pressure is applied to embed the maxillary dentition in the encasement and the lower incisor and molar occlusal surfaces in the encasement covering the zones.

An interocclusal appliance includes a maxillary impression preform of a resilient thermoplastic having a low softening temperature, e.g. 36&deg; C., such as an EVA copolymer having approximately thirty percent vinyl acetate. The preform is molded over and unitarily bonded to a base having a planar bottom face contacted by mandibular occlusal surfaces. The base is formed of a thermoplastic having a higher softening temperature, e.g. 70&deg; C., with the bond between the preform and base characterized by high shear strength. The preform includes a bight shaped centric relation positioning channel having a thick footing and draft along lingual, buccal and labial walls. The appliance is fitted by immersion in hot water to soften the preform, seating the maxillary arch within the channel and biting, such that the impression of the maxillary dentition embeds in the softened preform. Upon cooling, the preform is transformed into a reusable resilient encasement for the maxillary dentition. Suitable thermoplastics for implementation as the base include an EMA copolymer, blends of EMA and EVA or TPU or blends of TPU and EVA.
