Abstract

Abstract A periodontal and dental cleaning and periodontal stimulating device for both interdental spaces of anterior teeth and interproximal tunnels of posterior teeth comprising an elongated body member having a tapered configuration and fabricated of a material which is partially elastic and is deformable on contacting the hard surfaces of the teeth or firm, healthy gingival tissue, and a core member ensheathed within the body member. The core member is fabricated of a material which is generally stiff axially of its length and sufficiently bendable in all other directions when the device encounters the hard surfaces of the teeth and firm, healthy gingival tissue to enable the device to pass through the spaces and tunnels, but is also sufficiently resistant to bending to enable the device to depress or displace unhealthy, edematous or inflamed gingival tissue in the spaces and tunnels.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 344 words
A periodontal and dental cleaning and periodontal stimulating device comprising: an elongated body member having a forward end and a rear end, said body member being tapered in configuration from its rear end toward its forward end so that the cross-sectional configuration thereof progressively diminishes from said rear end to said forward end; and a core member disposed within said body member and extending substantially from said rear end thereof substantially to said forward eNd thereof; said core member being enclosed within and ensheathed by said body member; said core member being substantially circular in cross-section throughout its length; said device being adapted for insertion into and partially through the interdental spaces of a human''s anterior teeth and into and partially through the tortuous interproximal tunnels of a human''s posterior teeth; said body member having sufficient length between its forward and rear ends to permit the forward end thereof to enter the entrance openings of said interdental spaces and tortuous interproximal tunnels, pass through said spaces and tunnels, and exit through the exit openings of said spaces and tunnels before the rear end thereof reaches said entrance openings; said body member being fabricated of a material which is deformable to enable said body member to conform to the configuration of said spaces and tunnels, as such configuration is defined and formed between the lateral walls of adjacent teeth and the incisal and occlusal contact area limits and the gingival tissue; said core member being fabricated of a material which is generally stiff axially of its length to prevent pressure at the forward end of said body member from buckling said device, yet which material is bendable in all directions by forces applied by the surfaces of the teeth and healthy gum tissue laterally to said core member to enable said core member, and the body member ensheathing it, to pass through said interdental spaces and interproximal tortuous tunnels without damaging the gingival tissue present therein and yet sufficiently resistant to bending in all directions laterally to said core member to depress edematous gingival tissue.
Claim 2
Dependent Claim 344 words
A periodontal and dental cleaning and periodontal stimulating device comprising: an elongated body member having a forward end and a rear end, said body member being tapered in configuration from its rear end toward its forward end so that the cross-sectional configuration thereof progressively diminishes from said rear end to said forward end; and a core member disposed within said body member and extending substantially from said rear end thereof substantially to said forward eNd thereof; said core member being enclosed within and ensheathed by said body member; said core member being substantially circular in cross-section throughout its length; said device being adapted for insertion into and partially through the interdental spaces of a human''s anterior teeth and into and partially through the tortuous interproximal tunnels of a human''s posterior teeth; said body member having sufficient length between its forward and rear ends to permit the forward end thereof to enter the entrance openings of said interdental spaces and tortuous interproximal tunnels, pass through said spaces and tunnels, and exit through the exit openings of said spaces and tunnels before the rear end thereof reaches said entrance openings; said body member being fabricated of a material which is deformable to enable said body member to conform to the configuration of said spaces and tunnels, as such configuration is defined and formed between the lateral walls of adjacent teeth and the incisal and occlusal contact area limits and the gingival tissue; said core member being fabricated of a material which is generally stiff axially of its length to prevent pressure at the forward end of said body member from buckling said device, yet which material is bendable in all directions by forces applied by the surfaces of the teeth and healthy gum tissue laterally to said core member to enable said core member, and the body member ensheathing it, to pass through said interdental spaces and interproximal tortuous tunnels without damaging the gingival tissue present therein and yet sufficiently resistant to bending in all directions laterally to said core member to depress edematous gingival tissue.
Claim 3
Dependent Claim 54 words
A device according to claim 1, wherein said body member is formed from a partially elastic material so that on being deformed by the narrowest cross-sectional area of the interdental spaces or interproximal tunnels it will subsequently expand to conform to larger cross-sectional areas of the interdental spaces and interproximal tunnels on encountering them.
Claim 4
Dependent Claim 14 words
A device according to claim 1, wherein said body member is conical in shape.
Claim 5
Dependent Claim 14 words
A device according to claim 1, wherein said body member is triangular in cross-section.
Claim 6
Dependent Claim 17 words
A device according to claim 1, wherein said core member is a rod having a uniform cross-section.
