Abstract: A moldable portion for use with protective equipment, guards, braces, or the like for use to protect from injury and facilitate healing of the same are disclosed herein. This moldable portion includes a thermoplastic semi-crystalline propylene ethylene copolymer having a crystallinity of about 2% to about 65% that is between about 85% to about 99% of the moldable portion and a microwave susceptor that is about 1% to about 15% of the moldable portion These moldable portions may be adapted to be positioned adjacent an area of an user's anatomy it is intended to protect, and may be prepared for customization by heating to a temperature of about 60° C. to about 100° C. and shaped and configured to be affixed to a portion of the protective equipment.

Abstract: A self-customizable dental appliance adapted to lie within the mouth of a person including occlusal pads with a connecting arch or a u-shaped style base with upstanding labial and lingual walls. The appliance is formed of a semi-crystalline polyolefin polymer or crystallizable blend. In one embodiment, the appliance is formed of elastomeric propylene-ethylene polypropylene, optionally including high density polypropylene. An optional occlusal lifting pad can be used in the self-customizable dental appliance.
