Abstract: A tool tip (10) for a tool being intended for a dental treatment, in particular for a piezoelectric scaler, comprising—a first section (11) extending in a first direction (D1) and—a second section (12) extending in a second direction (D2), the second direction (D2) being inclined relative to the first direction (D1), wherein the first section (11) has at least partially a flat basic body (5).

Abstract: A tool (1) for a medical treatment, in particular for a dental treatment, comprising: —a handpiece (40) having an ultrasound vibration source (30), —a moving part (10), performing, in an operating state, a vibration movement in a vibration direction (VD), and —a tool tip (20), in particular a scaler tip, being connected to the moving part (10) in an interface section (15), wherein in a non-vibrating state the tool tip extends in an extending direction, being slanted to the vibration direction of the moving part (10), in the interface section (15).

Abstract: A tip element (1) preferably for a dental treatment device, in particular a scaler, wherein the tip element (1) performs an ultrasonic vibration during its utilization, comprising—a first end section (10) for reversibly attaching the tip element (1) to a hand piece, a second end section (20) forming a dental tool and—a motion transformation section (30) arranged between the first end section (10) and the second end section (20), wherein, for transforming an ultrasonic vibration having a first vibration direction (V1) to an ultrasonic vibration having a second vibration direction (V2), the motion transformation section (30) has a first bended subsection (31) and a second bended subsection (32).
