TR202018327A2 - Brushing methodology and wear assessment device - Google Patents

Abstract

The present invention relates to a brushing tester that abrades toothbrush, toothpaste and tooth specimens and observes the wear process. The aim of the invention is to develop a brushing test device that automates interim observations and measurements in order to determine the effectiveness and possible damages of the brushing process during the brushing of tooth samples using brushes and / or paste. A 3-axis brush movement has been added to simulate the reality of the brushing process of individuals. Circular brushing can also be done in this way and the sweeping style of brushing movement that physicians recommend to their patients will be simulated in this way and it is aimed to give an idea about the effective brushing method by comparing it with other methods. Another aim of the invention is to develop a mechanical and electronic system that will be used to detect abrasions on the teeth.

Description

DESCRIPTION SCRUBBING METHODOLOGY AND WEAR ASSESSMENT DEVICE Technical Area This invention uses tooth brush and toothpaste to use tooth surfaces and filling materials. a brushing methodology that monitors the wear and the wear process on the relates to the wear assessment device. Prior Art Equipment for testing toothbrushes and pastes, and tooth and filling materials for toothbrushes It is possible to observe the corrosive effects on These devices are long-term It is operated continuously so that the effects can be observed.

In the European Patent No. EP2405784, which is one of the examples known in the art, the paste is removed with a toothbrush. its abrasive effects on teeth and surrounding soft tissues during use An automatic device to be used for monitoring is mentioned. of this device brushing action; foodstuffs such as strawberries, textiles, chalk, sponges and plant leaves. It is done on the surfaces and the abrasive effects of brushing are compared. the effects of long-term use of brushes on the teeth, which are explained in the application devices that allow testing. Thanks to these devices, many It is possible to test tooth samples together with different brushes.

Purpose and Brief Description of the Invention The object of the invention is to make tooth samples using a brush and/or paste (paste together with the brush). the effectiveness of the scrubbing process during brushing (with or without use), It is a tool that automatically performs intermediate observations and measurements in order to determine the damages it may cause. It aims to develop the brushing test device. In this process, individuals brushing It is planned to simulate using the brush in different axes during

Another purpose of the invention is the mechanical and development of the electronic system.

Definitions of Invention Elements The scrub test device developed with this invention is given in figures for better explanation. The parts and parts in the field are numbered and the corresponding number of each number is given below. given. 1. Tester 2. Brush 3. Holder 4. Sensor(pr0be) . Weight Detailed Description of the Invention The subject of the invention is the brushing test device (1) under the long-term effect of the brush (2) of the tooth samples. It is used to observe wear. Tooth sample fixed under the brush (2) It can stand alone or by placing many teeth side by side as well as in the mouth. It is also possible to simulate the patient's mouth. The tooth as a sample, as well as the prosthesis or It is also possible to test a filled tooth sample.

The long-term abrasions that will occur on the tooth, filling and prosthesis due to the effect of the brush (2) are tested. It can be detected in a short time by continuous brushing with the device.

The movements of the brush (2) on the surface are periodically in the x, y and directions. will occur, unlike many brushing testers, the additional thanks to the movement in all 3 planes perpendicular to each other and forming the entire possible outer surface Circular brushing (including sweeping motion) on planes shall be simulated.

Sweeping brushing, which is the correct toothbrushing action recommended by dentists movement and the circular brushing method that patients frequently apply. effects can be observed. In addition, on the same tooth samples It is compared with the simultaneous experimentation of different types of brushing movements. results can be obtained. In this way, the physicians recommended to their patients Contribution to the literature by making studies on brushing and oral hygiene rules. is intended to be provided.

Thanks to the weights (5) superimposed on the carrier of the brush (2), the brush (2) The pressure force on it can be adjusted. The said thrust force In order for it to be even during circular brushing, the outer surface of the brushed should be horizontal. connection will be provided.

Components such as water and paste should also be brushed in order to fully observe the abrasion effect. It can be applied on the tooth by means of the test device (1) or it can be applied at certain intervals during can be sprayed. A 5-year scrubbing of the tooth sample subjected to wear inspection. 5 years with 3,600 repetitions of a 2-minute brushing session for The effect created by brushing twice a day can be observed throughout. This test is 5 days non-stop. can be completed with practice. During this test period, wear on the tooth Wear measurement shall be made periodically (at defined intervals) for understanding.

A probe (4) for wear measurement on tooth, denture and/or filling surface will travel. A session corresponding to a predefined value, such as every 6 months or 1 year brushing After the number of counts, the sensor (4) automatically checks the wear on the sample. will do. "x" and "y" so that the sensor (4) can fully scan the surface of the sample tangential measurement of the sensor (4) to the sample surface by moving it in the directions it will be provided.

In order for the sensor (4) to measure accurately, the sample surface must be cleaned.

Because the paste and contaminants remaining on the surface during the roughness measurement do not affect the measurement results. they will break it. For cleaning, clean the surface by spraying clean water on the sample. cleaning will be done.

The measurement of the roughness on the sample surface is also Detection of large fractures and sample displacement/extraction. it will provide. Wear of the brush (2) also causes an increase in roughness on the sample. can happen. For this reason, even the measurements on the sample alone, the brush (2) Feedback on the wear or replacement of the brush (2) during the testing process and/or The effect of the brush (2) change frequency on wear is also determined by the sensor (4) periodically. It can be determined by the measurements made.

Abrasions on the brush (2) and the sample; different toothpastes, brushes of different hardness (2) brushing (2) compression forces provided by different weights (5), speeds in different "x" and/or "y" and/or directions, the results of the brushing planes (different brushing methods), - ambient temperatures created by different water temperatures, It is possible to control comparatively. Even this parameter Measuring at the same time as differentiating some of the changes It can be performed with the test device (1) with sample and brush (2) clamping unit.

Images of the wear of a healthy tooth and an unhealthy tooth are shown in figure 5, figure 6, figure 7. shown. The wear control is especially "I", "i", "h" and "k" which are external wear. will check for changes in dimensions.
