Abstract

Abstract A method of and system for the treatment of periodontal diseases is disclosed wherein a patient, using a delivery device, applies a medicament directly to the infected site. The delivery device may comprise a piece of tufted dental floss, an interdental brush, a syringe, or a night time application tray for forcibly applying medicament to the infected site. The delivery device carries a supply of an antimicrobial or antibiotic medicament, preferably a tetracycline, dichloride or hydrogen peroxide solution or gel. By flossing, brushing, injecting, or by forcibly disbursing the medicament with the delivery device, the patient can apply the medicament directly on or in close proximity to the infected site (i.e., bony support structure of the teeth). The medicament (tetracycline) bonds with the bony structure to promote bone regeneration, decrease osteoclastic activity and to allow osteoblastic activity to continue with a consequent decrease in bone loss rate while promoting bone growth (regeneration). Through the use of an oxygenation agent (hydrogen peroxide), fluoride, dichloride, or other medicaments, microbial activity, plaque development, and pathologic processes are decreased.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 119 words
A method of treatment for periodontal disease wherein said disease causes deterioration of bone structure around or supporting a patient's teeth, said method comprising the steps of: delivering a medicament to the bony structure of the teeth affected by periodontal disease using a delivery device capable of being used by the patient without help from a dental professional so as to cause the medicament to at least partially bond with said bony structure thereby to substantially continuously slow osteoclastic activity and to allow a net positive osteoblastic activity and resulting in a net regeneration of the bony structure of teeth; and repeating such delivery of said medicament the extended course of treatment until the bony structure has sufficiently regenerated.
Claim 2
Independent Claim 119 words
A method of treatment for periodontal disease wherein said disease causes deterioration of bone structure around or supporting a patient's teeth, said method comprising the steps of: delivering a medicament to the bony structure of the teeth affected by periodontal disease using a delivery device capable of being used by the patient without help from a dental professional so as to cause the medicament to at least partially bond with said bony structure thereby to substantially continuously slow osteoclastic activity and to allow a net positive osteoblastic activity and resulting in a net regeneration of the bony structure of teeth; and repeating such delivery of said medicament the extended course of treatment until the bony structure has sufficiently regenerated.
Claim 3
Dependent Claim 44 words
The method of claim 1, wherein said step of delivering said medicament includes using a delivery device carrying a supply said medicament sufficient to treat all of the periodontal disease sites of the patient's teeth without re-application of the medicament to the delivery device.
Claim 4
Dependent Claim 52 words
The method of claim 1, wherein said step of delivering said medicament comprises flossing the periodontal disease sites with a length of dental floss, said floss having means for holding a supply of said medicament sufficient to treat all of the periodontal disease sites without re-application of the medicament to said floss.
Claim 5
Dependent Claim 22 words
The method of claim 1, further comprising the step of subgingvially applying said medicament to the exposed areas proximate said infected sites.
Claim 6
Dependent Claim 12 words
The method of claim 1, wherein said medicament is an antimicrobial medicament.
Claim 7
Dependent Claim 14 words
The method of claim 5, wherein said antimicrobial medicament is a solution of tetracycline.
Claim 8
Dependent Claim 25 words
The method of claim 6, wherein said tetracycline solution has the tetracycline equivalent of about 125 mg of tetracycline hydrochloride in a 5 ml quantity.
