摘要： Improvements in material-to-material connections are provided. For example, metal-to-metal connections are improved, such as the interface connection between a dental handpiece bur tube (10) and a component such as bearing (12). At least one marking, such as a laser marking (20) is provided such that an amount of excavate material (21) is excavated from the marking (20). When a component such as a bearing (12) is positioned upon the bur tube (10), a portion of the excavate material (21) is physically impinged between the two components (10, 12) filling any spaces or gaps therebetween.

摘要： A dental handpiece (10) of the type having a body (11), a head (13) and a neck (12), is improved by having at least one portion of the handpiece (10) formed by metal injection molding or MIM. The use of MIM allows for improved fabrication and function. According to one aspect of the invention, the head (13) and neck (12) of the handpiece (10) are MIM-formed as a single or unitary piece.

摘要： A detection system for remotely determining the speed of a rotating tool tip in a pneumatic dental handpiece. A means for detecting the speed of the rotating tool tip monitors a periodic mechanical function at the pneumatic hose connected to the handpiece. The monitored periodic mechanical function serves to provide feedback that is used to control the speed of the rotating tool tip. The means for detecting the speed of the rotating tool detects a mechanical function of the rotating tool tip, which in transmitted to a controller. The controller in turn regulates the operation of an air supply valve in response to the detected mechanical function. The valve regulates the flow of air to the handpiece. By continuously adjusting the flow of air through the valve into the pneumatic hose, the speed of the rotating tool is maintained at the desired cutting speed.
