Abstract: A hydraulically actuatable shift element (100) includes a clutch piston (101), a fast fill piston (102), a fast fill valve (103), a fast fill pressure chamber (126), and a clutch pressure chamber (117). The fast fill valve (103) includes a sealing body (132) and a control body (131). Before the actuation of the shift element (100), the sealing body (132) is in a first switching position, in which the fast fill pressure chamber (126) is connected to a pressurized oil source (108) and, after the actuation of the shift element (100) in a second switching position, seals off the fast fill pressure chamber (126) with respect to the rest of the hydraulic system. The control body (131) has a first pressure surface (A18) and a second pressure surface (A19), wherein, in the first switching position, only the first pressure surface (A18) is pressurizable from the pressurized oil source (108).

Abstract: A device for disinfecting, sterilizing and/or maintaining medical, especially dental, instruments comprises a maintenance and cleaning chamber for accommodating instruments to be conditioned and means for supplying different cleaning or maintenance media for cleaning, disinfecting or sterilizing and/or maintaining the instruments in subsequent steps. The start times of the conditioning cycles for the different instruments are staggered.

Abstract: A dental system may trans-illuminate teeth using a light source for producing examination radiation by directing the examination radiation at a tooth to be examined. An optical image of the tooth illuminated by the examination radiation may be acquired. The light source may include a light-guiding and/or light-deflecting element that faces the tooth to be examined being embedded in a transparent. The light-guiding and/or light-deflecting element may be embedded in a transparent, flexible coupling body that is provided to rest on the tooth or the gingiva of the tooth.

Abstract: In a dental system for the transillumination of teeth having a light source for producing examination radiation, irradiation means for directing the examination radiation at a tooth to be examined, and means for acquiring an optical image of the tooth illuminated by the examination radiation, the irradiation means includes light-guiding and/or light-deflecting elements, at least the light-guiding and/or light-deflecting element facing the tooth to be examined being embedded in a transparent, flexible coupling body that is provided to rest on the tooth or the gingiva of the tooth.

Abstract: A method and corresponding system for operating a dental handpiece, wherein the handpiece comprises a motor for driving a tool. the method comprises (a) sequentially capturing values of a physical parameter, which—at least approximately—represent the power or energy fed to the motor, (b) forming an integration value by integrating the values captured in (a), and (c) automatically reducing a power or energy fed to the motor if the integration value formed in (b) exceeds an upper threshold value. The integration value formed in (b) represents a measure of the power integrated over time and can thus be used at least approximately as a measure of the temperature of the instrument. The automatic reduction in the power or energy fed to the motor performed in (c) can therefore effectively act against a further increase in temperature or allow cooling if the temperature of the instrument exceeds an upper threshold value.

Abstract: A motor-driven handpiece, which has a grip sleeve with a head area for mounting a tool, in particular for the preparation of tooth substance and/or bone substance, in which the head area is at least partially surrounded or encapsulated by a thermoplastic material which, compared to the material of the rest of the grip sleeve, has a lower thermal conduction value.
