RU24092U1 - GALVANIC PIN - Google Patents

Abstract

A galvanic pin, consisting of an extra-channel part and an intra-channel part in the form of a needle, characterized in that the extra-channel part of the galvanic pin is a cylindrical head with a diameter of 4 mm and a width of 3 mm with a groove in the form of a linear recess 1 mm deep, and the intra-channel part is a cone-shaped needle with thread and two vertical grooves with a depth of 0.5 mm in its upper part, and the grooves are arranged symmetrically relative to the axis of the pin.

Description

The utility model relates to medicine, namely to therapeutic dentistry.

Despite the efforts of doctors, periodontitis remains a fairly common disease in the section of therapeutic dentistry. This obliges us to look for new methods and devices in the treatment of this disease.

An analogue of the claimed device, the authors propose a device for electrophoresis of depophoresis, which is used in the treatment of complicated caries of various types of periodontitis. It serves to introduce drugs into the area of the endodont and periodontium through the root canal system of the tooth and create a depot of the drug substance in these areas // Nedoseko V.V., Vetkova K.V. The use of copper phosphate hydroxide depophoresis in therapeutic dentistry, Moscow Clinical Stomatology, 2001, No. 10 p.27-30 //. At the same time, copper hydroxide of calcium is introduced in a small amount into the passable part of the root canal of the tooth, and an active electrode in the form of a needle is placed there. The passive electrode is fixed extraorally on the skin of the cheeks or lips. A device for electrophoresis of depophoresis is connected to the electrodes and the procedure is carried out in the liver for 10-20 minutes, using direct or alternating current of a small value of 0.2-1.5 mA.

The disadvantage of this device is the need for repeated visits to patients of a medical institution for conducting a course of electrophoresis, consisting of 3-10 procedures under the supervision of medical personnel.

To improve the quality of treatment, as well as to reduce the number of visits to the hospital, patients are offered a galvanic pin // Knappwost A. Neue Entwicklungen zur Depot-ioaaphorese von Kurpferverbingen, Zahnorztl. Z.

Depot-ionophorese von Kurpferverbingen, Dtsch Zahnorztl. Z. 1977, No. 32: P.463- 465 //, which the authors used as a prototype. This pin consists of intra-channel and non-channel parts. The pin is made of two metals that make up a galvanic pair (for example, copper-zinc, zinc-silver), which allows to obtain a constant electric potential inside the tooth canal. The non-channel part of the original pin is made in the form of a sphere with a diameter of 4 mm, the intra-channel part is made in the form of a needle. For depophoresis, the passable part of the root canal is filled with copper-calcium hydroxide and a galvanic pin is inserted into the channel. After this, the carious cavity of the tooth is closed with a temporary filling, leaving a medicinal substance and a pin in the tooth for 15-30 days, depending on the form of the disease. In the temporary filling, opposite the extra-channel part of the pin, a hole is made with boron, through which the exudate formed in the tooth should flow out during treatment. The presence of a small value of a direct current inside the channel (a few μA) and the duration of exposure allow a milder treatment without visiting a doctor during this period.

The disadvantages of the described device.-V-. - there is a need to create a temporary filling covering the tooth and drilling holes in it, which significantly reduces the strength of the temporary filling, and it is difficult to do technically.

The authors propose a galvanic pin, consisting of two parts: extra-channel 1 and intra-channel 2.

Design features of this pin:

The pin is made of two metals that make up the galvanic pair: the extra-channel part of copper or zinc and the intra-channel part of zinc or silver, respectively. Non-channel part: consists of a cylindrical head.

4 mm in diameter and 3 mm wide, on which there is a groove for a screwdriver 3 1 mm deep. The intracanal part is made in the form of a needle 7. The upper part of the needle is a downward converging cone 4 with a diameter of 3.5 mm at its widest point. There is a thread 5 on the cone. In addition, there are two vertical grooves b, 0.5 mm deep, symmetrically with respect to the pin axis. Next, the cone passes directly into the needle, the length of which, based on the clinical situation, can be adjusted by cutting it.

The advantages of this pin in contrast to the prototype are:

1. The thread on the top of the needle allows you to securely fix the pin in the root canal without resorting to the use of a temporary seal, which simplifies the work of the doctor.

2. Two vertical channels on the upper part of the needle provide free outflow of fluid and exudate resulting from the proteolysis of organic components from the tooth canal during treatment, which prevents the onset of a pain symptom and accelerates the elimination of inflammatory phenomena in the periodontium by reducing edema.
