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 the 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.
