Marking-plate dispenser for instrument that prepares tooth-root passage

摘要

The dispenser is box-shaped and comprises plates which limit the penetration depth of the preparing instrument. Part of the space between bottom and cover is of height roughly equal to the plate thickness, and a guide separates the individual plates and positions one at a point where there is a loading opening in the bottom and a further opening in the cover, a plate passing through both. A rib divides the space between bottom and cover into two chambers to accommodate plates of different types. Each chamber has a guide separating the plates and positioning them at the openings. When the dispenser is inserted in the loading sleeve, the latter covers both openings in the cover.
