Description

The utility model relates to medicine, namely dentistry, and can be used in the treatment of inflammatory diseases of peri-implant tissues.

A mouth guard for administering a medicinal product into the periodontal tissues is known (RU Patent No. 2339335, dated 18.06.2004). A cavity was made in the mouth guard, which created pressure inside the mouth guard, pressing the medicinal product into all the gum pockets near his teeth.

The disadvantage of this mouthguard is its low tightness, which leads to the loss of activity of medicinal preparations due to constant exposure to oral fluid.

A device is known for introducing preparations into periodontal tissues and a tooth canal with a permanent vacuum in the treatment of combined endo-periodontal pathologies. (Malanin I.V., Golub Yu.N. Modern science-intensive technologies. - 2005. - No. 4 - P. 50-52). The device is an elastic cap, made for the entire dental row, to which a hollow elastic balloon is attached, to create a permanent vacuum.

The disadvantages of this device are that its creation is quite labor-intensive, and its independent use at home is also excluded.

A custom-made mouth guard for the treatment of focal periodontitis is known (patent for utility model 222135, dated 12/12/2023). The custom-made mouth guard for the treatment of focal periodontitis is made with a cutout of the occlusal surface and adjacent vestibular and oral surfaces to the level of the necks of the teeth, and the space for placing the medicine is made in the area of the periodontal inflammation focus with a depth of 1-10 mm.

The disadvantage of this mouthguard in the treatment of peri-implantitis is the creation of weak pressure inside the mouthguard due to the existing cutout, which is unable to deliver the medicine under the peri-implant cuff.

A custom-made mouth guard for the treatment of periodontal diseases is known (RU Patent No. 136328, published on 10.01.2014), adopted as a prototype, with recesses for placing replaceable pads, is intended for the treatment of inflammatory periodontal diseases. On the inner surface of the custom-made mouth guard, on the vestibular and oral sides in the area of the necks of the teeth and gums, there are recesses 5-8 mm wide and 2-3 mm deep, allowing for the placement of disposable replaceable pads moistened with various liquid preparations for the treatment of periodontitis, ointment and gel preparations for the treatment of periodontitis on a fabric basis, after the use of which high-quality antiseptic treatment of reusable mouth guards is possible.

The disadvantage of the mouthguard is that oral fluid gets under the mouthguard. In addition, this mouthguard cannot be used to manage patients during acute inflammation and in the postoperative period due to contamination of the foam rubber with inflammatory exudate or wound discharge.

The technical result is an increase in the effectiveness of treatment of inflammatory diseases of periimplantitis.

The technical result is achieved in that the mouthguard is made in the form of an arc from a transparent acrylic polymer with a thickness of 1.5 to 3 mm, the guide chambers with a depth of 1 to 4 mm are made with the possibility of placing a medicinal product in the area of the inflammation site, inside which there are drainage grooves with a depth of 0.5 to 1 mm, which are directed perpendicular to the peri-implant cuff, while the edges of the mouthguard along the guide chambers from the inner surface are made of an elastic polymer, and along the outer surface of the mouthguard, at a distance of 2 to 3 mm from the edge, along the entire perimeter there is a rigidity profile with a thickness of 0.8 to 1.2 mm.

The device is illustrated by the following figures:

The mouth guard for application of the medicinal substance to the gingival or cuff edge is made in the form of an arc made of transparent acrylic polymer with a thickness of 1.5 to 3 mm. Using a thickness of less than 1.5 mm may lead to deformation of the mouth guard when closing the mouth and, as a consequence, to a breach of tightness and destruction of the drug by oral fluid. Increasing the thickness of the mouth guard to more than 3 mm may lead to inconvenience of its use. On the inner surface of the mouth guard on the vestibular and oral sides from the side of the implant 6 there are recesses - chamber guides 1 (Fig. 1, 2, 4, 6) with a depth of 1 to 4 mm with the possibility of placing the medicinal product in the area of the inflammation site. The depth of the formed bed is determined by the required volume of the medicinal product used. The edges of the mouthguard along the guide chambers from the inner surface are made of elastic polymer 2. Inside the guide chambers there are drainage grooves 3 with a depth of 0.5 to 1 mm, which are directed perpendicularly to the peri-implant cuff. Increasing the depth of the drainage grooves can weaken the mouthguard structure, and decreasing it can reduce the accuracy of delivering the medicinal gel to the inflammation site. On the outer surface of the mouthguard, at a distance of 2 to 3 mm from the edge of the mouthguard, along the entire perimeter, a rigidity profile 4 (Fig. 1-4, 6) with a thickness of 0.8 to 1.2 mm is made. The specified localization of the rigidity profile, increasing the elasticity of the mouthguard, is the most convenient location on the mouthguard for the patient. The size of the rigidity profile is set by the minimum thickness necessary to eliminate possible deformation of the mouthguard.

The production of a mouthguard is as follows:

After intraoral scanning of the upper and lower jaws, the boundaries of the mouth guard 10 are marked on the computer model of the jaw 9 (Fig. 4, 5). The model of the jaw 9 is obtained by computer modeling and volumetric printing, after which the guide chambers 1 are modeled above the inflammation site. Then, the model is scanned again. The mouth guard is made by computer modeling and milling. Then, the drainage grooves are cut out and the elastic polymer 2 and the stiffness profile 4 are attached. The mouth guard is made in two types: with an application on the implantation artificial crown 5 (Fig. 1) and with the implantation prosthesis removed on the implant plug 11 (Fig. 2).

The device operates as follows.

The medicinal product in the form of a gel is applied to the guide chamber 1 using a cotton swab or brush, the patient applies the mouth guard to the dental arch until it contacts the inner surface of the teeth so that he or she can close the mouth completely. The elastic polymer 2 facilitates the convenient application of the mouth guard, while a valve is created that prevents oral fluid and food from getting under the mouth guard, which significantly increases the tightness of the conditions inside the mouth guard and helps protect the medicinal product from destruction by oral fluid. The drainage grooves 3 located inside the mouth guard on the side of the guide chambers 1 direct the action of the preparation directly to the inflammation site in contact with the gum 8 (Fig. 1), the jaw bone 7 (Fig. 1) and the implant 6 (Fig. 1). The rigidity profile 4 helps to avoid deformation of the mouth guard when it closes with the antagonist teeth, thereby additionally maintaining the tightness inside the mouth guard and protecting the administered preparation from spreading under the mouth guard. The mouth guard is made in two types: with application to the implantation artificial crown 5 (Fig. 1) and with the implantation prosthesis removed, on the implant plug 11 (Fig. 2).

The proposed individually created mouthguard with insulation for obtaining guide chambers for the drug, drainage grooves and a rigidity profile allows for the introduction of drugs directly to the inflammation site in ointment and gel forms, strictly dosed and for a certain time, maintaining hermetic conditions. This mouthguard can be used in acute inflammatory processes, as well as a bandage in the postoperative period.
