On this day in 1967 Jack Cathcart was granted the patent for Custom Fittable Mouth Protector. U.S. Patent No. 3,333,582.
This invention relates to mouth protectors and more particularly to a mouth protector of the custom fittable type.
A custom fitted mouth protector is one fitted to the teeth of the individual who it to use it, and thus provides for better retention and greater comfort to the wearer. It is therefore to be preferred over one which is not so personalized.
