Dental cleaning instrument |
摘要 |
A dental cleaning instrument for cleaning the interproximal area between teeth is constructed with three threads of yarn. The first thread is initially supported on a first post and a second thread of yarn is supported on a second post. The third thread is wound on a bobbin and then interlaced around and between the first and second threads in a figure-8 pattern, while the first and second threads are simultaneously advanced in a direction normal to the plane in which the bobbin is moving. The resulting instrument consists of woven threads having a combined denier in the range of 480-1240, with superior spreadability and separation of ends.
