ABSTRACT:
A polishing dental instrument includes a polisher, which is vibrated by a drive shaft connected to a motor-driven drive via an eccentric pin. The eccentric movements are elastically transferred to two arms via two compression springs. The arms are fixed to a displaceably guided bearing sleeve positioned in a casing. The polisher which is guided in the bearing has an end piece whose lateral edges are adapted to smooth or clean the tooth root surface. As a result of the elastically transferred reciprocating movements of the eccentric pin a very fine smoothing of the root surface is obtained.
