RU202296U1 - Dental bur for the formation of diastema in a horse - Google Patents

Abstract

The utility model relates to veterinary dentistry. The task of the utility model is to create a boron that allows one to simultaneously expand the diastema (three), without the risk of causing iatrogenic injury to the animal. The problem is solved by placing on the cylindrical body of a bur (1) with an abrasive coating (2) and with a rounded working end (3), between the second end of the bur and its shank (4), free from abrasive chips of the ring 5. The ring acts as a passive limiter movement of the bur to exclude unintentional apical advancement. The surface of the rounded working end of the bur (3) is made without coating with abrasive grit. The technical result consists in the possibility of a controlled simultaneous expansion of the diastema (trema) between the distal teeth, especially in the area of insufficient visual control, to a width that does not interfere with the self-cleaning of tissues in the area of the teeth, limiting the diastema (trema), preventing injury to the swollen mucous membrane of the gums. 1il.

Description

The utility model relates to medicine, namely to veterinary dentistry, and is designed to create conditions that ensure self-cleaning of the interdental spaces of a horse's fragmented dental arch from food debris.

The anatomical norm in horses is a continuous dental arch. As a result of congenital or acquired pathology, as well as in connection with age-related changes, there is a possibility of the formation of diastemas and three different widths and shapes.

The presence of diastemas (and three) prevents the preparation of a food lump, which provokes the development of pathology of the chewing apparatus and the gastrointestinal tract. In addition, narrow diastemas less than 2.0-3.0 cm in size (Peter K. Goody, 2004 c.) Serve as retention points for food debris, increasing the likelihood of developing inflammatory-dystrophic diseases of the oral cavity. Diastema 2.0-3.0 cm wide is considered less pathogenic (Peter C. Goody, Topographic Anatomy of the Horse, Gordon Baker, Equine Dentistry; 2004, p. 113). The wider the diastema (or trema), the less the risk of accumulation of food debris, their rotting and as a result of inflammation of the gingival mucosa and underlying tissues. The diastema (or treme) can be expanded using a cone-shaped bur, used to shorten the extra-alveolar part of the tooth (page 67, Fig. 5).

The disadvantage of boron is the impossibility of forming the surfaces of the teeth, limiting the diastema (or three), without undercuts. Especially when working in the distal parts of the mouth (Borisov I., Roydev R., Diseases of the teeth in horses, J. Vetpharma, No. 4, 2012, pp. 64-67).

The closest in technical essence and the achieved result is a cylindrical bur by the Komet Company described in the catalog on page 4 No. S 6881.314 016. The structured diamond tool basically consists of a shank and a hardened profile element made of stainless steel, which is coated with selected grains by means of electroplating technology to provide a uniform, reliable and stable finish. Turbine shank. Bur shape: cylindrical, parallel shoulder shoulder, shortened, with a rounded working end surface. Rough processing. The grain size is 151 µm. Designed for preparation under a crown, preparation of cavities. This boron was taken as a prototype.

The disadvantage of the prototype is the execution of the working surface of the bur, which does not allow to simultaneously expand the diastema (three) to a width that does not interfere with the self-cleaning of the interdental spaces of the fragmented dental arch in the area of the teeth limiting the diastema (three). In addition, the use of the described bur can lead to the infliction of iatrogenic injury to the animal during the expansion of the diastema between the distal teeth in the area of insufficient visual control.

The task of the utility model is to create a bur that allows one to expand the diastema (three) at once, without the risk of causing iatrogenic injury to the animal in the process of expanding the diastema between the distal teeth.

The problem is solved due to the fact that on the cylindrical body of the bur with an abrasive coating, between the working part of the bur and its shank, there is a ring free from abrasive chips, which acts as a passive limiter of the movement of the bur, and part of the surface from the end of the working part of the bur adjacent to the ring is made not covered with abrasive grit.

The technical result consists in the possibility of a controlled simultaneous expansion of the diastema (three), between the distal teeth, especially in the area of insufficient visual control, to a width that does not interfere with the self-cleaning of tissues in the area of the teeth that limit the diastema (or three), and prevent injury to the swollen mucous membrane.

The claimed technical solution is illustrated by a drawing, where the figure shows a general view of a dental bur for the formation of a diastema in a horse:

Item 1 denotes a cylindrical bur body;

item 2 indicates the abrasive coating of the working side surface of the bur;

pos. 3 denotes the end working surface of the bur, free from abrasive;

item 4 indicates the shank of the bur;

Item 5 designates a ring free of abrasive grit.

A dental bur for the formation of a diastema (or treme) contains a steel cylindrical body 1, on the lateral working surface of which an abrasive coating 2 is applied, made using an abrasive of supercoarse grain size (GOST 9206), and the end rounded working surface of the bur 3 is free from abrasive, while , between the shank 4 and the surface of the opposite end of the cylindrical bur, the ring 5 is rigidly fixed, the diameter of which is 1/5 of the diameter of the cylindrical bur body, and the height (thickness) of the ring is 2-2.5 mm.

A dental bur for the formation of a diastema (trema) in a horse works as follows.

To form a diastema (trema), boron is introduced into the horse's oral cavity, pushing apart soft tissues with a rounded working end 3, while a cylindrical bur 1, with its lateral working surface of a bur, covered with an abrasive material of supercoarse grain size 2, expands the gap between the teeth (coating with an abrasive supercoarse grain allows minimize intervention time). The presence of ring 5 (passive limiter of unintentional apical advancement of the bur) prevents the removal of hard tissues from the occlusal surface. At the same time, the end face of the bur 3, free from abrasive chips, pushes the gum away without causing injury to it in the event of inflammation associated with the impossibility of self-cleaning of the interdental spaces of the fragmented dental arch, leading to uneven edema of the gum tissue. Equipped with a ring and abrasive restriction, a bur, pushing apart the tissues of the interdental space, expands the gap, then ring 5 comes into action, which prevents injury to the surface of the gums and soft tissues of the tongue, palate and inner surface of the cheek.

Thus, the task has been solved and the result, which consists in a one-stage atraumatic formation of a diastema (three), especially in the area inaccessible to adequate visual control, has been achieved.
