Abstract

The present invention is directed to devices and methods for administering at least one effective dose of at least one therapeutic substance to at least one of the maxillary sinuses of a patient in need thereof. Alternate embodiments may comprise administration of the at least one effective dose of at least one therapeutic substance to both maxillary sinuses, where the administered therapeutic substance(s) are either the same or differ from sinus to sinus. Still further alternative embodiments may comprise more than an initial effective dose administered to a patient'"'"'s maxillary sinus(es), so that the therapeutic substance may be delivered over time, thereby requiring a larger dose be deposited within at least one of the maxillary sinuses so that the maxillary sinus(es) serve as a therapeutic substance depot for long-term release to the target structure(s).

Claims

1. A method to treat a patient'"'"'s periodontal disease and the symptomatic anatomical structures innervated by the trigeminal nerve and in need thereof, comprising:

providing a delivery device adapted for insertion into the patient'"'"'s nasal cavity and operative connection with one of the patient'"'"'s maxillary sinus opening;

inserting the delivery device into the patient'"'"'s nasal cavity until it reaches at least one of the patient'"'"'s maxillary sinus openings;

administering at least one effective dose of at least one therapeutic compound selected from the group consisting of an analgesic, an anesthetic, an anti-inflammatory compound, an antioxidant compound, an antiviral, an antibiotic, and bone morphogenic protein (BMP) via the delivery device through the at least one maxillary sinus opening, wherein the at least one effective dose comprises a volume of at least 0.3 milliliter;

depositing the at least one effective dose within the maxillary sinus; and

treating the structures innervated by the trigeminal nerve with the at least one therapeutic compound.

2. The method of claim 1, further comprising treating a patient with endodontic disease.

3. The method of claim 1, further comprising treating a patient with orthodontic pain.

4. The method of claim 1, further comprising treating a patient with temporomandibular disorder.

5. The method of claim 1, further comprising treating a patient in need of scaling, root planning and/or deep cleaning.

6. The method of claim 1, further comprising treating a patient in need of a root canal treatment.

7. The method of claim 1, further comprising treating a patient with dental caries.

8. The method of claim 1, further comprising treating a patient in need of full mouth reconstruction.

9. The method of claim 1, further comprising treating a patient before and/or while moving the patient'"'"'s teeth with braces.
