Cofferdam brace for use in dentistry

摘要

The connecting rib (3) tensions the two clamp jaws (1, 2) in relation to one another. Each clamp jaw has at least one locating surface (6) locatable against a tooth (4). The locating surfaces have a friction-increasing top layer, which is structured, being diamond-impregnated. In the area of each clamp jaw, an operating surface is formed, which can be brought into engagement with an insert tool, and which is provided with a friction-increasing top layer. The operating surface is formed as a recess (8, 9) in the clamp jaws (1, 2). It is also structured, with diamond impregnation.
