Description

The technical field to which the utility model relates.

The invention relates to the field of medicine, in particular, to dental prostheses with a clammer system on a dental bone implant and can be used in orthopedic dentistry.

State of the art

A known implant according to the method of surgical preparation of the lower jaw for prosthetics consists in the fact that a spherical hole is made in the bone tissue, a spherical insert made of elastic material is inserted into it and an implant is screwed into the insert, made in the form of a screw with a wedge-shaped leg, while before closing the implant, the mucosa - a periosteal flap under it is placed a demineralized bone graft (see US Pat. RU No. 2125845, IPC A61B 17/24, publ. 02/10/1999).

The disadvantage of this implant is that when biting, there is excessive pressure on the jaw bone in the area of the implant seat and injures the jaw bone.

A dental bone implant is known, comprising first and second bone grafts, wherein the first bone graft is sized and shaped so as to fit snugly against the buccal surface of the periodontal alveolar process around at least one tooth and reconstruct at least one tooth part of one or more periodontal bone defects, the second bone graft is sized and shaped to fit snugly against the lingual / palatal surface of the periodontal of the alveolar bone around at least one tooth and reconstruct at least one additional part of at least one periodontal bone defect, this part and additional part together complementarily cover one or more periodontal bone defect (see US Pat. RU No. 2518131, class A61F 2/28, A61C 8/00, published on 10/10/2012).

The disadvantage of this implant is the complexity of manufacturing, trauma and breaking the implant seat.

The closest in technical essence and the achieved positive effect, and adopted by the authors as a prototype, is a clasp system for fixing a partial denture with a single tooth, consisting of a base with artificial teeth and a clasp, with a mechanical device consisting of patrician internal and external matrix, made in the form of a hinge, and at the second end - the seat of the clasp in a fixed socket on an artificial tooth crown, while the external matrix for it is mounted in the basis of the prosthesis with the possibility of a scheme together with the prosthesis, and the inner patricia is made spherical and connected to the shoulder of the clasp, and the seat in the clasp nests is made on an artificial tooth crown vertically or horizontally with a lingual, palatine, or approximate surface.

In a clasp system, the system is mounted on a plate prosthesis.

In the clasp system, the outer matrix is fixed in the saddle part of the arch prosthesis (see Pat. RU No. 2538641, IPC A61C 13/00, A61C 13/265, A61C 13/267, publ. 10.01.2015).

The disadvantage of this clamping system is that when biting, the system exerts excessive pressure on the jaw bone in the area of the seat.

Utility Model Disclosure

The objective of the proposed utility model is the development of a dental prosthesis with a clasp system on a dental bone implant, with the exception of pressure and trauma to the jaw bone in the area of the implant seat, improved blood flow, decreased atrophy of the bone tissue and mucous membrane of the entire jaw, relieving pressure on the mucous membrane during opening teeth, increasing the service life of the remaining teeth.

The technical result that can be obtained using the proposed utility model is to eliminate pressure and trauma to the jaw bone in the area of the implant seat, improve blood flow, reduce atrophy of the bone tissue and mucous membrane of the entire jaw during opening of the teeth, and increase the service life of the remaining teeth.

The technical result is achieved using a dental prosthesis with a clasp system on a dental bone implant, consisting of an implant with an abutment and a clasp system, while at one end of the clasp there is a mechanical device consisting of an internal patrician and an external matrix, made in the form of a hinge device, and on the second end - the seat of the clasp in a fixed socket on the abutment, while the outer matrix is fixed in the base of the prosthesis with the possibility of removal with the prosthesis, and the patrician the inner one is spherical in shape and connected to the shoulder of the clasp, while the clasp seat for the implant abutment is made in the form of a ring, which is then installed under the abutment, fixed with the help of the latter with the possibility of depreciation of the prosthesis on the implant using a clasp system.

Utility Model Implementation

A dental prosthesis with a clasp system on a dental bone implant consists of an implant 1, an abutment 2, a clasp system (not indicated in Fig.), While at one end of the clasp there is a mechanical device consisting of an internal patric 3 and an external matrix 4, made in the form hinged device 5, and at the second end - the seat of the clasp in a fixed socket 6 on the implant 1, the matrix 4 is external, which is fixed in the basis of the prosthesis with the possibility of removal with the prosthesis, and the inner patricia 3 is made ovidnoy shape and is connected to the clasp shoulder 7, wherein the seat clasp in the implant 1 at abutment 2 is made in the form of a ring 8 which is then positioned under the abutment 2 is fixed by the latter, with the depreciation of the prosthesis on the implant 1 by means klammernoy system.

A dental prosthesis with a clammer system on a dental bone implant is made and installed as follows.

At one end of the clasp, a mechanical device is fixed, consisting of an internal patricia 3 and an outer matrix 4, made in the form of a hinge device 5, and at the second end, a clasp seat is mounted in a fixed socket 6 on the implant 1, the outer matrix 4 of which is fixed in the basis of the prosthesis ( or the intermediate part of a fixed prosthesis) with the possibility of removal together with the prosthesis, and the internal patricia 3 is spherical and connected to the shoulder 7 of the clasp, while the seat of the clasp for the abutment 2 is made in the form of rings 8, which is then mounted at the abutment 2 is fixed by the latter with the possibility of damping the prosthesis on the implant 1 by means klammernoy system then bone spherical operate well, it is set to implant 1 to the existing methods.

Thus, the proposed dental prosthesis is in limbo and does not compress the tissue of the prosthetic bed during opening of the teeth, when biting, the prosthesis is immersed in the mucous membrane of the prosthetic bed by the amount of mucosal compliance, and when opening the mouth, the prosthesis returns to its previous position, while it It massages tissues under the prosthesis, improves blood flow, reduces atrophy of bone tissue and mucous membranes, and extends the life of remaining teeth. To chew food, the masticatory muscles develop significant pressure, it would turn into a destructive force, hammering a tooth into the hole, if there were no morphological structures in the periodontium (see. Theory and prosthetics clinic with partial removable dentures. EI Gavrilov, “Medicine”, 1966, p.), And since a removable prosthesis with a clasp system works as a shock absorber, it replenishes the lost opportunities of the periodontium and stops further excessive destruction of the periodontium. Given these theoretical developments, it can be assumed that the absence of periodontal implant 1 leads to detrimental consequences, and the presence of a clammer system protects the implant 1 seat from destruction and increases the life of the implant 1.

Example. Patient K., born in 1940, complained of poor fixation of complete dentures after a three-time prosthesis. Objectively: the mucous membrane of the transitional fold is attached at a level of 3-4 mm from the top of the alveolar process, on the alveolar part it is thinned, anemic, not palpable, painless on palpation. Diagnosed with type III atrophy of the toothless lower jaw according to A.I. Doinikov. Surgical preparation is proposed - implantation, which was carried out after preliminary anesthesia. Implants with a pre-installed clasp system according to the proposed utility model were inserted into the bone to a depth of 7.0 mm in the area of missing 32, 23 teeth, the mucoperiosteal flap returned to its place, the wound edges were sutured. The patient was examined after 10 days, the condition of the mucous membrane of the alveolar part was assessed as normal, the palpation was painless, there was no hyperemia and inflammation, a removable prosthesis was made and installed. Chewing function does not suffer, fixation and stabilization is good, the patient successfully uses prostheses.

A removable prosthesis with a clasp system on the dental bone implant was installed on another 5 patients, which also gave positive results.

The proposed utility model in comparison with the prototype and other well-known technical solutions has the following advantages:

- the exclusion of pressure and injury to the jaw bone in the area

seat

- improvement of blood flow;

- reduction of atrophy of bone tissue and mucous membrane;

- increase the service life of the remaining teeth;

- the ability to massage the tissues under the prosthesis.
