US 2015/0086941 A1 · DENTAL TREATING APPARATUS

Abstract

A dental treating apparatus according to the present invention includes: a hand piece; a head unit; a driving unit; a resistor for load detection; a load comparing unit; and a control unit. The hand piece drivably holds a cutting tool on the head unit. The driving unit drives the cutting tool in a normal rotation direction or in a reverse rotation direction. The resistor for load detection detects a load applied to the cutting tool. The load comparing unit compares the detected load and a reference load each time driving for rotating the cutting tool in the reverse rotation direction by a predetermined rotation angle is performed. The control unit controls the driving unit based on a result of comparison by the load comparing unit.

Dependent claims

A dental treating apparatus, comprising:

a hand piece for drivably holding a cutting tool on a head unit;
a driving unit for driving said cutting tool, assuming that a normal rotation is a rotation in a direction in which said cutting tool cuts an object to be cut and a reverse rotation is a rotation in an opposite direction of said normal rotation;
a load detecting unit for detecting a load applied to said cutting tool;
a load comparing unit for comparing the load detected by said load detecting unit and a reverse rotation reference load;
and
a control unit for controlling said driving unit based on a result of comparison by said load comparing unit, each time said driving unit performs driving for rotating said cutting tool in said reverse rotation direction.
