PURPOSE: An ultrasonic scaler tip for the implant operation is provided to be able to maintain the scaling function to a specified level even when the end part of the ultrasonic scaler tip for the implant operation is worn away to some extent. CONSTITUTION: An ultrasonic scaler tip for the implant operation comprises a body portion(310) and an end part(320) formed on the leading end of the body portion. In the end part, multiple grooves are successively formed so that a protrusion part is formed. In the body portion, a coolant flow way is formed so as to supply cooling water to the end part. The boundary of the body portion and the end part is the abrasion limit.
