Description

The utility model relates to medicine, namely to maxillofacial surgery and surgical dentistry, and can be used to close the socket after tooth extraction and to prevent atrophy of the alveolar bone and gums after tooth extraction.

Currently, dental implantation is a priority in dentistry. Therefore, the problem of full-fledged tissue regeneration in the area of the socket of the extracted tooth or "preservation of the socket" is relevant and one of the most important issues of modern surgical dentistry [Fevraleva A.Yu., Davidyan A.L. Atlas of plastic surgery of soft tissue around implants. M .: Poly Media Press, 2008. - S. 82-83].

A known method of closing the hole after tooth extraction using resorbable and non-resorbable membranes [Pikos M.A. Maxillary sinus membrane repair: Report of a technique for large perforations. J. Implant Dent, 1999 - No. 8 - P.29-34].

The disadvantage of this method is the complication of surgical intervention, the need for additional fixation of membranes. The use of these membranes is not always effective and is characterized by significant financial costs.

The known method of plastics of the alveoli after tooth extraction (Patent RU No. 2282408, IPC A61B 17/24 - 27.08.2006, Bul. No. 24), including filling the hole with osteoplastic material, closing the hole with a flap, fixing the flap with sutures to the edges of the wound, characterized in that two vertical incisions are made along the edges of the hole from the vestibular side, the muco-periosteal flap is separated, then, departing from the distal edge of the flap, the periosteum is dissected and separated from the mucous membrane to the distal edge of the flap, while leaving the periosteum attached at the distal edge of the flap, filling the hole tightly of the tooth with hydroxyapatite granules, the formed flap from the periosteum is rotated at an angle of 90 ° and the socket of the extracted tooth is covered.

Disadvantages: the use of additional material - hydroxyapatite, additional trauma - incisions and separation of the flap, the complexity of manipulation without skills.

A known method of treating a "dry hole" (Patent RU No. 2417780, IPC A61C 19/00, A61K 31/41, A61K 33/06, A61K 35/14, A61P 1/02 - 05/10/2011, bull. No. 13), consisting in the fact that a mixture prepared from the patient's blood of a fibrin clot and powder of calcium hydroxyapatite and metrogil (0.5 g) is injected into the socket of the extracted tooth. The clot is formed by taking blood from the patient's vein in an amount of 15-25 ml, followed by centrifugation at a speed of 10-12 thousand rpm for 5-7 minutes. Then the hole is closed with a collagen membrane "Taho-Comb", which is fixed with sutures to the edges of the gums.

Disadvantages: the possibility of infection of the Tacho-Comb membrane, inflammation and suppuration of the contents of the hole, the development of alveolitis with subsequent atrophy of the alveolar process, as well as a long time spent on fixing the membrane (15-20 minutes).

A known method for the prevention of atrophy of the alveolar bone and gums after tooth extraction (Patent RU No. 2604389, IPC A61M 1/38, A61C 19/00, A61K 31/216, A61K 35/14, A61P 1/02 - 10.12.2016, bull. 34), which consists in the fact that a preliminary blood sample is taken from the patient's vein, a fibrin clot is prepared from it, and the clot is mixed with a filler. Blood sampling is carried out in two 10 ml tubes. A fibrin clot in test tubes is obtained by centrifuging blood at a speed of 1300 rpm for at least 8 minutes. A clot from one tube is mixed with 0.5 g of the drug "Osteomatrix". The resulting mass is filled with the tooth socket. The clot from the second tube is squeezed out to extract the liquid phase and used as a membrane covering the well. The edges of the hole are sutured with two z-sutures. At the same time, 3 days before and 4 days after tooth extraction, oral baths of 0.01% Miramistin solution are used, 20 ml 3 times a day.

Disadvantages: the complexity of blood sampling in a dental surgery room, the use of additional equipment-centrifuges, the use of additional material - "Osteomatrix".

A known method of treating a wound after tooth or implant extraction (Patent RU No. 2238047, IPC A61B 17/24, A61K 38/39 - 20.10.2004, Bulletin No. 29), which consists in filling the hole with a bone modulator and closing the wound with a wound covering in the form of collagen a plate covered with a layer of fibrin glue components, which is placed under the exfoliated soft tissue.

Disadvantages: lack of free access to a collagen plate covered with a layer of fibrin glue components, additional financial costs.

This product is taken as a prototype.

The objective of the claimed utility model is the possibility of closing the socket after tooth extraction and direct loading on the alveolar process in order to reduce the degree of atrophy of the alveolar process.

The technical result of the utility model is to simplify and accelerate the closure of the socket after tooth extraction, visual control over the healing process of the socket, load on the alveolar ridge in the area of the extracted tooth.

The technical result is achieved by the fact that a device is used to close the hole after tooth extraction with a mono-product made of medical silicone, consisting of a saddle-shaped supra-alveolar part 6-7 mm wide, 4-5 mm high, 7-8 mm thick with two oval concave membranes extending from it 0.7-1.0 mm thick, enclosing the alveolar process outside and inside.

The essence of the utility model is illustrated by drawings, which show:

figure 1 - General view of the device;

figure 2 - View of the device superimposed on the hole after tooth extraction.

In the figures, the following positions are indicated by numbers: 1 - saddle supraalveolar part, 2 - semi-oval concave membranes.

Implementation of the utility model.

The device for closing the socket after tooth extraction is made in the form of a mono-product made of medical silicone, for example, from the manufacturers of Forplast, Kraton, AlphaGary, Kraiburg, and consists of a saddle-shaped supraalveolar part 1 with a width of 6-7 mm, a height of 4-5 mm, a thickness of 7- 8 mm with two oval concave membranes 2, 0.7-1.0 mm thick, extending from it, enclosing the alveolar process outside and inside.

After tooth extraction with passive postoperative treatment, due to the lack of load on the alveolar process, its atrophy occurs on 1 / 3-1 / 4 of the alveolar process against the background of microcirculation disorders associated with both general and local causes. Therefore, the load on the alveolar process in the area of the socket of the extracted tooth will reduce its atrophy.

The device for closing the socket after tooth extraction works as follows, see Fig. 2. The device is placed on the socket of the extracted tooth with the saddle part and the oval membranes are pressed against the alveolar process, squeezing air from the concave part. There is a suction of membranes to the mucous membrane of the alveolar process. We recommend that the patient eat in the usual way, because the chewing surface is preserved, but after eating, rinse your mouth with antiseptic agents. The next day, a re-examination is carried out for the presence of the device, as well as through transparent silicone - inspection of the hole without removing the device. If it falls out, we teach the patient to independently apply the device to the socket of the extracted tooth. The treatment is carried out within 2-3 weeks.

Thus, the claimed method for closing the socket after tooth extraction, in comparison with the prototype, has a simpler technique and consists of a device in the form of a mono-product made of medical silicone, consisting of a saddle-shaped supra-alveolar part with two oval concave membranes extending from it, enclosing the alveolar process from the outside and inside with the possibility of self-application and removal by the patient at home.
