Therapeutic device for massaging gingival tissue

Claim 1

A therapeutic device for, inter alia, massaging gingival tissue comprising a body member having an arcuate longitudinal conformation so as to fit the mouth from front to rear, said body member including first and second longitudinally extending webs, and a transverse web bridging between said first and second longitudinally extending webs, said first and second longitudinally extending webs each respectively issuing upwardly and downwardly from substantially opposite ends of said transverse bridging web, said first and second longitudinally extending webs and said transverse web defining upper and lower generally superposed channels in said body member, said upper and said lower channels respectively accomodating teeth in the upper and lower jaws of a user of said device; said transverse bridging web comprising first and second overlying webs of predetermined thickness, said first and second overlying webs defining therebetween an interiorly located continuous transverse slot, said first and second overlying webs being compressible through the area of said transverse slot for elastically impermanently deforming said first and second longitudinally extending webs inwardly towards the clinical crowns of teeth and into the gingivae of a user of said device; said first and said second longitudinally extending webs each carrying at least one interiorly located substantially linear slit extending continuously therethrough, said at least one slit in each of said webs terminating in at least one graduated notch of predetermined configuration, said first and second longitudinally extending webs being respectively expansible about its at least one slit in opposite correspondence to a compressive force exerted upon said transverse bridging web, and each of said first and second longitudinally extending webs including a corresponding pair of interior surfaces, each pair of said interior surfaces issuing incipiently oppositely from said transverse bridging web through a corresponding pairs of chamfers, said chamfers having a continuous emphasis throughout said device; said first longitudinally extending web having an upper and a lower end, each of said upper and said lower ends having a discretely aligned plurality of slots therein, each of said slots opening outwardly into a corresponding upper and lower channel, and said second longitudinally extending web having an upper and a lower end, each of said upper and lower ends having a discretely aligned plurality of slits therein, each of said slits in said second longitudinally extending web corresponding to a slot in said first longitudinally extending web, said first and second longitudinally extending webs being respectively contractable through the areas of their respective slots and slits as a compressive force is exerted through said transverse bridging web for thereby overfitting the clinical crowns of teeth and abutting the gingivae of a user of said device.
