1. A gum growth pad comprising:
a) a nonporous first layer; b) an absorbent second layer placed upon and in contact with said nonporous first layer; c) a dried medication capable of being liquified by saliva impregnated within said absorbent second layer; d) a semi-permeable third layer covering said absorbent second layer with said dried medication forming a pocket completely filled by said absorbent second layer; and e) means for sealing said nonporous first layer to said semi-permeable third layer about a periphery thereof.
14. The method of delivering medication at a controlled rate directly onto human tissue within the mouth of a person utilizing a pad, said pad consisting essentially of a nonporous first layer, an absorbent second layer on one side of said nonporous first layer, and a semi-permeable third layer covering the absorbent second layer forming a sealed pocket completely filled with said absorbent second layer, said method comprising the steps of:
a) impregnating said absorbent second layer with medication in a liquid form and then drying said medication; and b) placing said pad within the mouth of said person with the semi-permeable third layer in contact with the tissue to receive said medication for permitting the saliva within said mouth to penetrate said semi-permeable third layer causing the dried medication to liquify and diffuse through said semi-permeable third layer.
20. A method of delivering medication at a controlled rate onto buccal mucosa tissue within the mouth of a person by utilizing a pad, said pad consisting essentially of a nonporous first layer, a medication-carrying second layer on one side of said nonporous first layer, and a semi-permeable third layer covering the second layer and sealed to said nonporous first layer so as to enclose the second layer therein, said method comprising the steps of:
a) impregnating said second layer with medication which is capable of being liquified by saliva and transported in liquified form by diffusion from said second layer; and b) placing said pad within the mouth of the person with the semi-permeable third layer in contact with the buccal mucosa tissue in order to have saliva from within the mouth of the person penetrate the semi-permeable third layer to liquify the medication in the second layer and cause the saliva-liquified medication to diffuse through the semi-permeable third layer onto the buccal mucosa tissue.
19. A gum pad comprising:
a) a nonporous first layer which is stable and flexible such that it can be mounted in place on the gums in the mouth of a person; b) a second layer placed upon and in contact with said nonporous first layer; c) a medication carried in said second layer which is capable of being liquified by saliva and transported in liquified form by diffusion from said second layer; d) a semi-permeable third layer covering said second layer which is permeable to saliva from the mouth of the person, such that, when said gum pad is mounted with said nonporous first layer on the gums of the person and with said semi-permeable third layer in contact with buccal mucosa tissue facing toward the gums, saliva can penetrate through said semi-permeable layer to said medication-carrying second layer and liquify the medication therein and transport it in liquified form by diffusion through said semi-permeable third layer to the buccal mucosa tissue of the person; and e) means for sealing said nonporous first layer to said semi-permeable third layer so as to enclose the second layer, therein.

growth pad 10 comprising a nonporous first layer 12 with an absorbent second layer 14 placed upon the nonporous first layer 12. A medication 16 in a liquid form is impregnated within the absorbent second layer 14 and then dried. A semi-permeable third layer 18 covers the absorbent second layer 14 with the dried medication 16. A facility 20 is for sealing the nonporous first layer 12 to the semi-permeable third layer 18 about a periphery thereof. The medication 16 is may be a gum tissue growth substance 21. The nonporous first layer 12 is applied high up or low down against the gum tissue 26 of the teeth 28 in the mouth of a person 24, with the semi-permeable third layer 18 against the buccal mucosa 22. Saliva in the mouth of the person 24 will penetrate through to the semi-permeable third layer 18 and cause the dried gum tissue growth substance 21 in the absorbent second layer 14 to liquify and diffuse through the semi-permeable third layer 18, to enhance the growth of the gum tissue 26, reverse age related gum recession, protect against gingival disease and loss of teeth 28. The nonporous first layer 12 contributes stability, but allows flexibility, so that the pad 10 can adapt to the cavity without buckling or curling.
As best seen in FIG. 3, the nonporous first layer 12 is a synthetic thermoplastic sheet 30. The absorbent second layer 14 is a sponge-like cushion 32. The semi-permeable third layer 18 is a thin membrane sheet 34. The sealing facility 20 is a hot-bond adhesive 36.
The gum growth pad 10, as best seen in FIGS. 4 and 5, has an elongated generally tubular shaped body 38 with bulb shaped ends 40, to supply a large posterior area of the gum tissue 26 and help stabilize placement between the buccal mucosa 22 and the gum tissue 26 of the teeth 28. The nonporous first layer 12 is flat, while the semi-permeable third layer 18 is curved on the tubular shaped body 38, so as to fit snugly and comfortably between the buccal mucosa 22 and the gum tissue 26 in the mouth of the person 24.
The gum tissue growth substance 21 can be a drug diphenylantoin sodium known as by the trademark name DILANTIN, which is ordinarily used to treat and prevent seizures, with a well known side effect for gingival hyperplasia. DILANTIN has recently been shown to stimulate the formation of bone, as well as gum tissue.
The gum tissue growth medication 16 can also be an immuno-suppressant agent, such as cyclosporin or nifedipine. Immuno-suppressant agents are also known to stimulate gum growth. The gum tissue growth medication 16 can also be a nerve growth factor, a protein gene product, or a bone growth protein. Bone growth protein stimulates the repair of bone and tooth-anchoring connective tissue. All these substances have the potential of preventing and treating periodontal disease.
To use the gum growth pad 10, the following steps should be taken:
1. Apply the nonporous first layer 12 high up or low down against the gum tissue 26 of the teeth 28 in the mouth of the person 24.
2. Make sure that the semi-permeable third layer 18 is against the buccal mucosa 22.
3. The dried gum tissue growth substance 21 in the absorbent second layer will become liquified when saliva in the mouth of the person 24 penetrates through the semi-permeable third layer 18.
4. The liquified gum tissue growth substance 21 will diffuse through the semi-permeable third layer 18, to enhance the growth of the gum tissue 26.
5. The gum growth pad 10 will not interfere with speech and cause no discomfort.
6. Application of the gum growth pad 10, two to three times weekly, will regenerate the tooth anchoring connective gum tissue 26 to help protect against gingival disease.
