摘要： In a method for controlling a torque of a motor of dental and surgical handpieces to not exceed a set-point value when screwing in implant members, a motor current for applying the set-point torque is determined immediately before screwing in an implant member with the handpiece and the motor current is limited to the set point value with a motor control during subsequent screwing in of the implant member. The device for carrying out the method has a torque limiter, connectable to a tool receptacle of a handpiece, and a motor current measuring device for measuring a motor current of the motor of the handpiece.

摘要： A fluid supply system that may be used interchangeably to supply fluid for use in dental instrumentation including irrigation, application, aeration, and evacuation for treating a patient's mouth. The fluid supply system includes a dental handpiece that has at least one valve arranged within and operably disposed upon said handpiece, and is used to allow flow between the fluid supply system and the patient's mouth. The fluid supply system can also be used to decontaminate dental unit water lines when used with anti-microbial fluids such as sodium hypochlorite.

摘要： An exhaust manifold for a dental handpiece system receives at an inlet thereof return air flow provided by a dental handpiece. A unidirectional valve couples the inlet to a common manifold space which in turn couples to ambient air by way of a filter. By applying filtration on the backside of the unidirectional valve, air entering the common manifold space cannot thereafter reenter the return air conduit and thereby contaminate the same handpiece or other handpieces in a multiple handpiece system. A replaceable filter unit avoids accumulated debris and promotes better sanitary conditions.
摘要翻译：用于牙齿手柄系统的排气歧管在入口处接收由牙齿手柄提供的回流气流。单向阀将入口连接到公共歧管空间，该歧管空间又通过过滤器耦合到环境空气。通过在单向阀的后侧上进行过滤，进入公共歧管空间的空气不能在此再次进入返回空气管道，从而在多个手持件系统中污染相同的手持件或其他手持件。可更换的过滤器避免积聚的碎屑，并促进更好的卫生条件。

摘要： A dental instrument support mechanism for establishing stable support for dental instruments such as a dental cutting tool, a drill, a fiber scope and the like. The dental instrument support mechanism is formed with a base portion, and a support arm connected to the base portion at one end for holding a dental instrument at another end. The dental instrument held by the support arm is fixedly maintained a positional relationship with a dental object in an oral cavity of a patient. The dental instrument support mechanism is attached to one of a head, face, jaw, tooth of the patient or a treatment bed.
