Dental treatment device with variable cooling
摘要:
In the case of a treatment device, in particular a dental treatment instrument, having a tool, such as a dental drill, driven by a drive unit, and a conduit for delivery of a cooling medium to a treatment site worked by the tool, the quantity of the cooling medium delivered to the treatment site is dependent upon the removal power of the tool or upon the torque exercised by the tool.
