PCT No. PCT / EP97 / 05118 Sec. 371 Date Mar. 16, 1999 Sec. 102(e) Date Mar. 16, 1999 PCT Filed Sep. 18, 1997 PCT Pub. No. WO98 / 16169 PCT Pub. Date Apr. 23, 1998In order to ensure a good cleaning of the interdental spaces, an interdental cleaner comprises an elongated, rod-like carrier of a first plastics material, which is covered in partial areas of its surface by at least one insert or support made from a second plastics material, which is softer than the first plastics material. The insert can be placed in a recess formed in the carrier and positively held therein. If the first plastics material of the carrier and / or the second plastics material of the insert or support contains one or more additives, the cleaning and care action can be varied and optimized. For the production of an interdental cleaner, the second plastics material of the insert or support is injection moulded onto the first plastics material of the carrier, the carrier and the insert or support being manufacturable in a two-component injection moulding process.

Description

technical field [0001] The present invention relates to an interdental cleaner or a toothpick and a method of manufacturing a corresponding interdental cleaner or toothpick. Background technique [0002] It has been scientifically proven for some time that cleaning the interdental space is of special importance for maintaining the health of the teeth and especially of the periodontium, since gum disease and disease of the periodontal tissue, so-called periodontitis, are the most common In some cases, they originate from the interdental space. The cause of the above-mentioned morbidity is mainly due to lack of cleaning of the interdental spaces, wherein the lack of cleaning of the interdental spaces leads to osteolytic processes. [0003] It has been found that the interdental spaces cannot be adequately cleaned with manual or electric toothbrushes, necessitating the use of special cleaning devices. Dental flosses known for a long time, such as dental floss, have not been s...

AI Technical Summary

Problems solved by technology

The tooth contact area cannot be cleaned with a wooden toothpick as there is still a risk of caries formation

[0005] In addition, there is a disadvantage when using wooden toothpicks: for reasons of stability, due to their low bending stiffness, they must have a certain cross-section or core diameter, which is larger than the opening of the slightly open interdental space, so that they cannot into the narrow cross-sectional area of ​​the interdental space

This process is labor intensive and therefore interdental cleaners are relatively expensive to manufacture
