Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a hand-held dental implant for applying a drug to the subgingival space to prevent and treat periodontitis. This invention relates to a device for preventing and treating peritis.

(Conventional technology) Periodontal disease is a major cause of tooth loss in adults.

The first step in preventing periodontal disease is maintaining an oral environment free of food debris, detached tissue, and bacteria.

Brushing with a toothbrush and toothpaste is helpful in keeping the oral cavity clean, but it is not very effective at removing food debris and plaque buildup from between the teeth. And it has little effect in the subgingival space.

Dental plaque remaining in the subgingival space causes gingivitis, an inflammation that is considered a precursor to periodontal disease.

(Problem that the invention seeks to solve) Medications are available that are effective in killing bacteria in the gums and reducing gingivitis and periodontal disease. However, it is difficult for consumers to administer drugs to the subgingival area at home. Recognizing this problem, manufacturers invented a device called the "water pik". It passes pressurized water through a small, retained nozzle that hits the teeth and gums and helps remove food debris. However, this device is unsuitable for administering medication into the subgingival space, and even if it does, the medication will remain in the cavity.

An object of the present invention is to provide a periodontitis prevention and treatment device that can inject a viscous or gel-like drug into the subgingival space or between the gums for the treatment of gingivitis and periodontal disease. .

SUMMARY OF THE INVENTION The present invention is an improvement on US Pat. No. 4,617,918.

The device of the invention is filled with a suitable drug, can be held in the hand,
It consists of a tube that can be squeezed. The drug has the fluidity of a gel and is administered through a tube extending at a physiological angle. The tube is fitted with a tip made of elastic rubber or synthetic resin having an orifice of appropriate size.

The device of the present invention is used by removing the protective cap from the elastic tip. This tip is then inserted into the proximal area towards the crus. Holding the device in this position, gently push its tip into the subgingival space. The tube is then pressed to force the drug through the extension tube and flexible tip into the subgingival space. This procedure is repeated on the side and side of each tooth, including the gum margin.

(Example) Hereinafter, the present invention will be described in detail with reference to the accompanying drawings. In the accompanying drawings, the same parts are designated by the same numbers throughout. 1
0 shows a complete hand-held periodontal device according to the inventive concept.

Device 10 includes a housing 12 having a threaded aperture 14 adapted to receive an externally threaded neck 16 of a container from which medicament can be contained and expressed. The tube 10 may be made of synthetic resin or metal, and may be of a collapsible type or of a flexible type. A handle 2 provided integrally with the housing 12
0 extends along the container or tube 18, but extends slightly away from the container to facilitate operation of the device 10 while squeezing the container or tube 18.

To facilitate application of the drug, housing 12 has a tubular portion or passageway 22. The tubular portion or passageway 22 extends at an angle with the rest of the housing at an angle of 20 to 45 degrees, preferably 30 degrees, from coaxial with the container or tube 18. A further offset passageway 24 extends at an angle to the passageway 22, and the passageway 24 extends toward the passageway 24 at an angle of 30 degrees in a direction opposite to the axis of the container or tube 18. This angle is variable between 20 degrees and 45 degrees, but 3
0 degrees is most desirable.

A flexible tip 28 is provided at the end of the passageway 24, with a drug passage groove 26 tapering toward the tip 28, optionally to provide the desired size and shape of the drug to be applied. It is also possible to obtain

A cap 30 may be provided at the end of tip 28, as shown in FIG. Bead 32 on cap 30
is provided, and in cooperation with the bead 34 of the tip 28, the tip 2
8 snap closure mechanisms.

In another cap embodiment shown in FIG. 4, the tip is 28°
Threads 42 are formed on the inside of the cap 40 to mate with threads 44 on the tip 28' for closure.

In FIG. 3, a pushable, refillable valve 50 is shown. The valve 50 has an externally threaded neck portion 52 for releasably securing it to the housing 12.

The valve 50 is formed of a resilient, resilient material such as rubber or a plastic with rubber-like properties. When the housing 12 is squeezed, the valve 50 functions as a manual pump to intermittently force the drug toward the tip, and the squeezed /
8 and a baffle 60 to restore the original state. screen 5
8 allows air to enter through the air intake 56 but prevents drug from exiting from the air intake 56. Baffle 60 reduces the possibility of air intake 56 becoming clogged.

In use, the angle of the passageway and the position of the tip 28, 28' facilitates positioning the tip in the desired position, and the angled passageway facilitates visualization within the oral cavity.

Appropriate yield point of gel drug
significantly improves the effectiveness of the products used. If the yield point is too high, it will be difficult to apply the product through the small opening in the tip. thixotropy
A characteristic required for drugs is low xotropy. The drug is subjected to large shear forces as it is forced through the small opening in the tip. Rapid reconstruction of the solid structure will improve retention of the product within the subgingival space and at the gum margin.

The gel-like drug used for the treatment of gingivitis mentioned above is made from appropriate antibacterial agents, oxygen treatment agents, antibiotics, anti-inflammatory agents, anti-calculus agents, sodium bicarbonate, and other substances recognized as effective for the treatment of gingivitis. Become. The device also uses fluoride, calcium chelate,
um chelating) and antinuclear substances (antin).
Gel-like agents such as nucleating ingredients) or other suitable substances can also be used for removal. It can also be used to apply local anesthetics such as benzocaine to relieve pain in the inflamed area.

If desired, it can also be used to apply drugs that do not have a yield point or have low rheology, such as water. Agents of this type can be easily applied with this device.
