Description

The present invention relates to a dental treatment device and the use of a powder or a scale tip for such a dental treatment device.Tooth treatment devices are known from the prior art. For example, the prior art describes dental treatment devices provided for a tooth prophylaxis. Such a tooth prophylaxis is provided for removing calculi, plaque, discolorations and / or biofilms from the tooth. Typically, a scale and / or powder gas jet unit is used to remove and clean the tooth. In the last 20 years, such dental treatment devices have been optimized for different tooth regions and even allow the cleaning of a tooth in the periodontal pocket comprising delicate dentin at the tooth root. However, treatment of such regions requires substantial adaptations to avoid damage to the teeth. Therefore, devices designed, for example, for carrying out various dental treatments, in particular using the same instrument, such as a scale or a powder gas jet unit, must be configured such that their operating parameters can be adjusted accordingly in order to avoid damage to the tooth, in particular to the tooth dentin. In the past, several approaches have been introduced into powder gas jet units and / or scalers to avoid the incorrect operational setting being a risk to a patient. For example, it is known from the prior art that a pressure for a powder chamber in which the powder-gas mixture is generated is adjusted when the powder chamber is replaced. Thus, it is possible to use different powder chambers, each of which is specified for a particular powder or dental treatment. These powder chambers may be replaced and the proper gas pressures adjusted to produce the desired powder-gas mixture.Document WO 91 / 07 144 discloses a mouthrinse device which can be operated in a first operating mode and a second operating mode. The output of the discharged liquid in the first mode is different from that in the second mode, and by using a switch, switching can be performed between the first and second modes. It is provided that the switch automatically returns to the position for the first operating mode as soon as it is no longer actuated by the user. This allows switching between two operating stages during treatment.With the state of the art in mind, the technical object of the present invention is to provide a dental treatment device which further simplifies the handling of the dental treatment device and in particular reduces the risks to a patient treated during the treatment.The object is achieved by a dental treatment device according to claim 1 and the use of a powder or a scale tip for such a dental treatment device according to claim 14. Advantages and preferred embodiments of the invention are discussed in the dependent claims, the specification and the figures.According to a first aspect, a dental treatment device is provided which comprises a powder gas jet unit and / or a scale, wherein the dental treatment device is configured for operating a handpiece and comprises a base station, wherein the dental treatment device comprises a control unit which is configured and defined such that it resets, in particular automatically, at least one operating parameter on the dental treatment device for carrying out a dental treatment after and / or before a treatment cycle.Contrary to the prior art, it is provided that by using the control unit, the at least one operating parameter is reset before and / or after the treatment cycle, in particular before and / or after each treatment cycle. In particular, it is provided that the at least one operating parameter is reset to a defined and / or predetermined operating parameter before and / or after each treatment cycle. This ensures that, at the beginning of a new treatment cycle, clearly defined operating parameters are set by the user, which parameters are known to the user and are expected by the user. As a result, it is no longer necessary for the user to check which operating parameters are currently set in order to avoid incorrect parameter settings leading to an operating mode hazardous to the patient. The risk of injury to a patient is even reduced, since it can be avoided that at the beginning of the treatment cycle an adjustment of the operating parameters is inadvertently used, which could be dangerous for the tooth and / or the patient.It is preferably provided that the at least one operating parameter which is reset is not zero. As a result, it is advantageously possible to start directly with the next treatment cycle and not to adapt the operating parameter to a value different from zero if the at least one operating parameter is zero at the beginning.The powder gas jet unit is intended to provide a powder-gas mixture jet directed at a tooth surface to remove calculi, plaque, discolorations and / or biofilms. In this case, the powder gas jet unit also ejects a flushing fluid, in particular flushing liquid, which encloses the ejected powder-gas mixture jet. If the powder-gas mixture impinges on the tooth in order to abrasively influence the tooth surface, dust formation can thus be reduced by the flushing fluid. To provide the powder-gas mixture, the tooth treatment device comprises a powder chamber. The powder chamber can be reversibly attachable to the base station, in particular to an upper side of the base station and / or to a side wall of the base station.The powder chamber is preferably configured to store and accumulate powder, preferably in a powder accumulation component. Such a powder accumulation component can be conical, semi-conical and / or funnel-shaped. The accumulation component may include an inner sidewall facing the tube, the inner sidewall being inclined with respect to a longitudinal direction of the tube. Preferably, the inclination of the inner side wall is varied over a direction parallel to the longitudinal direction, in particular in order to avoid bridging effects of the powder.The powder chamber is in particular configured to generate the powder-gas mixture within the powder chamber. Therefore, the powder chamber comprises, for example, a gas inlet and a powder-gas mixture outlet. Thereby, the powder chamber not only retains the powder, but is also used for generating the powder-gas mixture within the powder chamber. For the production of such a powder-gas mixture, a tube, for example a Venturi tube, is used, for example. The tube is preferably arranged within the powder chamber, in particular within the powder accumulation component. The tube has a first end face and a second end face which are arranged opposite each other. The first end face faces the gas inlet, while the second end face ends within the swirl section. In use, gas entering the gas inlet is directed to the first face end of the tube and passes through a portion between the gas inlet and the first face within the powder accumulation surface comprising powder. Thereby, powder is transported through the tube to the second end side to enter the swirling portion of the powder chamber. The powder is mixed with the gas in the swirling portion to produce the powder-gas mixture which leaves the powder chamber via the powder-gas mixture outlet. The gas inlet and the powder-gas mixture may be integrated into components on opposite sides or into a common component, for example a base on one side of the powder chamber. Alternatively, it is also conceivable for the powder-gas mixture outlet to be located in a closure, preferably a removable closure or cover, while the gas inlet is arranged on the underside in a base of the powder chamber. The tube can be arranged centrally, in particular concentrically to a housing of the powder chamber, or offset from the centre in a cross section perpendicular to the tube. In this case, an asymmetric funnel having no rotational symmetry with respect to each rotation may preferably be used.In particular, the tooth treatment device is configured to perform at least two different treatments for the powder gas jet unit. In particular, it is provided that the powder gas jet unit is configured to carry out a subgingival treatment and / or a supragingival treatment. Depending on the type of treatment, the powder chamber may be replaced, in particular to use the correct powder in the abrasive powder-gas mixture.The scale serves to remove calculi, biofilms and / or dirt from the tooth surface by scraping. In particular, the dental treatment device comprises an ultrasonic scaler configured to perform a vibratory movement of the scaler instrument tip in use. Preferably, the scleral instrument tip is interchangeably attached to a handpiece of the sclera. The handpiece of the scale preferably comprises a vibration source which is implemented, for example, by a stack of piezoelectric elements. Depending on the shape and design and / or the wear state of the dental instrument tip, the amplitude and / or frequency of the vibration movement can be adapted. The handpiece of the powder gas jet unit may comprise a permanently installed nozzle element. Alternatively, it is also conceivable for the nozzle element to be attached to the handpiece in an exchangeable manner. The powder gas jet unit, in particular the handpiece including the nozzle element, is designed for modification for a specific dental treatment. For example, it is conceivable that a nozzle tip can be attached to the outer front side of the powder gas jet unit, i.e. at the distal end of the powder gas jet unit, in order to adapt the powder gas jet unit for a specific treatment, in particular for a subgingival treatment, which makes it necessary for the powder-gas mixture to exit laterally.Furthermore, it is provided that the handpiece of the powder gas jet unit is connected to the base station via a supply line. It is also conceivable for the handpiece to be connected directly to the powder chamber without the powder-gas mixture being initially transferred into the base station and subsequently into the supply line which is connected to the handpiece of the powder gas jet unit. The handpiece of the scale is preferably connected to the base station and comprises electrical signal lines and a flushing fluid line for providing electrical signals, in particular for the vibration source and the flushing fluid, respectively.It is also conceivable for the powder chamber to be arranged directly on the handpiece. Such devices, which are referred to as "cell phones", are also included within the terms handpiece and dental treatment device within the meaning of the invention.The base station is in particular the centre for the organization of the supply of materials and / or signals for the operation of the scale and / or the powder-gas mixture. It therefore supplies on the one hand the required signals and / or materials, for example the powder-gas mixture and / or the flushing fluid, and on the other hand electrical signals, for example the signal for the scaler, in order to operate the powder-gas jet unit and the scaler in a suitable manner. The base station may also be part of a dental chair.In particular, it is provided that the base station also has a control unit which is preferably designed to adapt the operating parameters during the treatment. For example, the base station comprises a human-machine interface, which comprises, for example, a command button and / or a display for setting the operating parameters during dental treatment. In this case, without looking at the device, the user can set the parameters while cleaning the tooth. At a point in time, he can be clear of the set parameters, for example if he places the dental instrument or the powder gas jet unit and / or the scale on the carrier only for a short time. There may be situations, however, where the user is distracted and does not know the current operating parameters when resuming use. In this case, it may start a new treatment cycle to ensure that the proper and desired operating parameters are set.Preferably, the operating parameters, which are in particular different from zero, represent a low or a minimum performance value which is used for the most gentle treatment possible with the tooth treatment device.In particular, it is provided that a trigger event is defined, so that upon the occurrence of the trigger event, the treatment device resets the at least one operating parameter to a defined and determined, in particular predetermined, operating parameter.Preferably, the handpiece and the base station are connectable or connected to one another in a non-treatment mode, wherein the control unit is designed and set such that it resets the operating parameter when establishing and / or cancelling the connection in order to form a trigger event. In this case, the handpiece can be simply connected to a holding element, for example the base station, and the control unit receives the information that the handpiece has been attached to the base station or removed therefrom. This triggers a signal for resetting the at least one operating parameter. Such an approach is particularly advantageous because it even allows the user to reset the operating parameters simply by returning the handpiece to the base station, rather than manually returning the parameter values to the original operating value, for example, via a display or command button. This simplifies the handling of the tooth treatment device.For example, the holding elements and / or the base station comprise a weight detector or an optical detector which detects the attachment or removal of the handpiece to or from the base station. In a specific embodiment, the handpiece or the retaining element is attached to the side of the base station. However, it is also conceivable for the handpieces to be mounted, in particular suspended, on the front side of the base station when they are connected to the base station.Preferably, it is provided that the control unit is designed and defined such that it resets the at least one operating parameter for dental treatment during or after a cleaning mode. This ensures that the correct operating parameters are set each time a cleaning mode is called. This can be advantageous in particular when a treatment has to be interrupted, since cleaning is absolutely necessary and the user waits until the use is ended. In order to ensure that the user uses the correct operating parameters after restarting the treatment, the cleaning mode also triggers a reset of the operating parameters.Preferably, it is provided that the control unit is designed and defined such that it resets the operating parameters when the tooth treatment device is switched on and / or off. As a result, it is possible, for example in the event of a power failure and / or restart of the system, to continue the process since the user knows the set operating parameters known to him.Preferably, it is provided that the at least one operating parameter relates to a fluid pressure. It is also conceivable that this operating parameter is set differently for the powder gas jet unit and the scale. For example, the operating parameter comprises two different values, one value being provided for the powder gas jet unit and the other value being provided for the scale. Preferably, it is provided that the operating parameter relates to a vibration mode of the scale. This makes it possible to automatically adjust the forces that can be used by the scale.It is also possible to set a water flow rate for the scale to a value between 30 ml / min and 50 ml / min. Preferably, the preset operating value is close to the minimum value, for example, 30 ml / min. The water flow rate for the scale is equal to or different from the water flow rate in the powder gas jet unit. In particular, it is also provided to use the minimum value for the operating parameter which is reset by the control unit.For example, it is provided that a power of the scale, i.e. the power used for actuating the vibration source formed by piezoelectric elements, is set to a value between 1.7 and 3.4 W. This set and predetermined operating value is different from those values that can be used in a boost mode with a power of between 3.4 and 6.8 W.According to a further approach, the operating parameters relate to a pressure of the gas for producing a powder-gas mixture. For example, the normal pressure is between 1950 and 2150 mbar and a pressure between 2800 and 3000 mbar is available in a boost mode. Preferably, the operating parameter is set to a value used in the normal operating mode, preferably having the lower minimum of the operating mode.In particular, it is provided and intended that the reset is carried out for a set of operating parameters, which includes the operating parameter relating to a vibration mode of the scale, the operating parameter relating to the pressure of the gas for generating the gas mixture and / or the operating parameter relating to the fluid pressure. A data set preferably stored in the control unit preferably comprises the set of operating parameters to be reset, wherein the data set is automatically used for resetting all these values in order to establish the same state for the entire treatment apparatus at each triggering of the reset, for example by attaching the handpiece to the base station or at another triggering event.It is also conceivable that the at least one parameter is reset in response to the triggering event and another parameter is reset in response to another triggering event. This allows additional handling of the powder jet device by selectively triggering certain triggering events in order to bring about a certain and desired reset of the at least one parameter or of the other parameter.Preferably, it is provided that the control unit is designed and defined such that the operating parameters are automatically selected depending on a user and / or patient. This is a more personalized selection of operating parameters that can increase the comfort for the patient and / or user. For example, it is possible for the treatment device to identify the current patient and / or user and to set the standard values to a specific value selected for this user and / or patient. As a result, it is possible, for example, to use a specific set of operating parameters as the standard operating parameters if the patient reacts extremely sensitively to the scale and the powder-gas mixture. It is also possible to adapt it, for example, for children or older people who may have different sensitivities to the various dental treatments.Preferably, it is provided that the tooth treatment device has a status signal element which is designed and defined in such a way that it notifies the user during the treatment whether the operating parameter has been changed. In particular in the case of long-lasting treatments, the user can forget that he has already changed the operating parameters during the treatment. The status signal element, for example a corresponding LED or a corresponding light, advantageously informs the user about the change. For example, it is conceivable that a light turns off as soon as the operating parameter previously reset by the tooth treatment device has been changed. The user can thus easily return to the preset operating parameters to continue the process.It is further provided that the tooth treatment device has a powder chamber arranged interchangeably on the base station, wherein the control unit is configured to determine the operating parameters when the powder chamber is exchanged. It is preferably provided that the powder gas jet unit is designed such that it can handle different types of powder chambers. These powder chambers can be interchanged with one another and preferably require different pressures which are generated within the powder chamber in order to provide the optimized powder-gas mixture for a particular treatment. These powder chambers are part of a set of different powder chambers which can be replaced by removing or attaching the powder chamber. The operating parameters can also be adapted to this replacement of the powder chamber. In other words, the operating parameters used for the one powder chamber may deviate from the operating parameters reset for the second powder chamber. Consequently, the control unit is designed and defined to store and process different sets of operating parameters for resetting, in particular depending on the powder chamber attached to the base station.Preferably, it is provided that the dental treatment device has an exchangeable instrument tip, wherein the dental treatment device is designed and determined to set the operating parameters after the exchange of the instrument tip. In particular, the operating parameters can be adapted, for example, to the working state and / or the type of instrument tip attached to the powder chamber. This also ensures less hazardous treatment for the patient, taking into account all aspects of the dental instrument used.Preferably, it is provided that the tooth treatment device is designed and determined such that the operating parameters are adjusted when the handpiece performs a defined movement. For example, it is conceivable for the handpiece to have an acceleration or orientation sensor, for example a MEMS sensor. Such sensors are known, for example, from mobile telephones which serve to determine the current orientation of the mobile telephone. These can also be used in the handpiece to automatically reset to the default values. This allows, for example, the user to be reset to the standard values or the operating parameters by a defined movement. For example, a fast up and down movement or a fast rotation allows the values to be reset. This simplifies the treatment considerably and simplifies, in particular, the setting of the parameters.Preferably, it is provided that the control unit is integrated into the base station. Alternatively, it is also conceivable for the control unit to be located outside the base station.A further aspect of the present invention is the method for operating a dental treatment device according to the present invention, wherein the at least one operating parameter is set,when a handpiece is attached to or removed from the base station, and / orwhen the cleaning mode is carried out, and / orwhen the dental device is switched on and / or off.All specifications and advantages discussed and explained in connection with the tooth treatment device apply analogously to the use of the tooth treatment device and vice versa.A further aspect of the present invention is a use of the powder in the dental treatment device, in particular in its powder chamber or in a scaler, in particular an ultrasonic scaler, according to the present invention. Another aspect of the present invention is a use of a scaler tip in the dental treatment device according to the present invention. All the advantages and specifications discussed in connection with the dental treatment device apply analogously to the use of the powder / the scale tip and vice versa. The powder preferably has a grain size of less than 25 μm. In particular, the powder is intended for carrying out a subgingival or a supragingival treatment. This ensures a gentle and comfortable treatment, in particular in the case of a supragingival treatment. In particular, the powder comprises glycine, erythritol and / or chlorhexidine digluconate. The use of such a powder is advantageous in particular since it ensures that a probability of clogging or caking is reduced, in particular by using the filter liquid from the network, in particular in the nozzle element, in particular if a filter system is used. Furthermore, the dental treatment device is optimized for the powder and the scleral tip, so that the advantages of the invention are developed in particular by using the powder and / or sclera. At the scleral tip, the expelled flushing fluid is optimized to the position of the tapered tip end of the scleral tip, particularly to aid removal in the treatment zone. Further, data analyses can be evaluated more accurately because they are based on experiences of those powders and / or scale tips that can be used in the dental appliance. The dental treatment device is preferably marketed as EMS AIRFLOW Prohylaxis Master. In particular, the dental treatment device can inform a user whether the correct powder or the correct scale tip is used.Unless expressly described, individual embodiments or their individual aspects and features can be combined or interchanged without limiting or expanding the scope of the described invention if such a combination or such an exchange is expedient and within the meaning of this invention. Advantages described with respect to one embodiment of the present invention are also advantageous for other embodiments of the present invention where applicable.In the figures: FIG. 1 shows a tooth treatment device according to a first embodiment of the present invention in a perspective view, and FIG. 2 shows a tooth treatment device according to a first embodiment of the present invention in a schematic view.Referring to FIG. 1, a dental treatment apparatus 100 according to a first embodiment of the present invention is shown. In particular, the dental treatment device 100 comprises a powder gas jet unit 10 and / or a scale 20. The powder gas jet unit 10 is preferably used to provide a powder-gas mixture jet to remove calculi, plaque and / or biofilms by abrasive action of the powder-gas mixture impinging on the tooth surface. In particular, it is provided that the powder gas jet unit 10 is configured to provide a jet of the powder-gas mixture which is surrounded by a fluid, in particular a flushing fluid, which reduces the dust formation in a targeted treatment zone which is struck by the jet of the powder-gas mixture. In particular, the powder gas jet unit has a handpiece 11 and a nozzle element 12. The powder gas jet unit 10 is preferably provided for carrying out different tooth prophylaxis treatments, in particular a subgingival treatment on the one hand and a supragingival treatment on the other hand. Depending on the treatment provided, the nozzle element 12 may be modified, for example by replacing the nozzle element 12 and / or by adding a nozzle tip to the nozzle element 12, the nozzle tip allowing, for example, penetration into the periodontal pocket to suitably treat a tooth root without risking injury to a patient.For generating the powder-gas mixture, the dental treatment device 100 comprises a powder chamber 13, which is preferably attached to an outer side of the base station 30. Depending on the treatment provided, a selection of the powder and / or the settings for generating the powder-gas mixture can be changed. Specifically, the powder chamber 13 is provided not only for collecting and storing powder but also for generating the powder-gas mixture inside the powder chamber 13.Preferably, the powder chamber 13 comprises a powder accumulation component, for example formed by a conically shaped funnel, which preferably has a step-like internal course in order to avoid bridging of the powder.The powder chamber 13 further comprises a gas inlet, preferably at a bottom side of the powder chamber 13, and a powder-gas mixture outlet, preferably arranged at the top side of the powder chamber 13. The powder chamber 13 preferably comprises a tube, in particular a Venturi tube, which has a first end face facing the gas inlet and a second end face end which ends within the swirl section. The tube is preferably arranged within the powder accumulation component, in particular in such a way that a space is formed between the gas inlet on the one hand and the first end-face end of the tube on the other hand. This allows the gas flowing into a powder accumulation portion to force powder provided by the powder accumulation component to enter the tube at the first end face and to be accelerated toward the second end face and supplied to the swirl portion. After the powder-gas mixture has been generated in the swirl section, the powder-gas mixture exits from the powder chamber 13 preferably via an outlet channel which is introduced into a closure on the upper side of the powder chamber 13.In the embodiment shown in FIG. 1, the powder chamber 13 and the tooth treatment device 100 are configured such that the powder chamber 13 can be exchanged in a tool-less manner. In particular, in the embodiment shown in FIG. 1, a clamping mechanism is provided which clamps the powder chamber 13 between the clamping element 17 and the base station 30. The clamping element 17 further comprises an inner channel for guiding the powder-gas mixture into the base station 30 for being supplied to the handpiece 11 via a supply line 14. In the embodiment shown in Figure 1, a supply line 14 is connected to the base station 30. However, it is also conceivable for the supply line 14 to be connected directly to the powder chamber 13. It is also conceivable that the powder chamber 13 is arranged only on the upper side of the base station 30 and is configured such that the powder-gas mixture outlet and the gas inlet are arranged in a base region of the powder chamber 13.For switching between different treatments, it is preferably provided that a set of different powder chambers 13 is present, which are each specialized for a specific dental treatment or can at least be prepared by the user for different treatments. Thereby, it is possible to modify the dental treatment system 100 and prepare it for another dental treatment by merely selecting the powder chamber 13 and replacing the powder chamber 13 with the desired powder chamber 13. The different powder chambers 13 comprise, for example, different powders, which differ from one another, for example, in the grain size and / or the type of powders used. Thus, it is possible to use the correct powder, especially for subgingival treatment requiring a smoother abrasive action.The dental treatment device 100 from FIG. 1 comprises, in addition to the powder gas jet unit 10, also a scaler 20 which can be used for removing dental stone and / or dental plaque. In particular, this scaler 20 comprises a scaler tip, i.e. an instrument tip 22, which can be interchangeably attached to a handpiece 21. The handpiece 21 is connected to the base station 30 preferably via a supply line 24 which preferably comprises electronic control lines and / or a flushing fluid line. In particular, the scaler 20 is an ultrasonic driven scaler. Such an ultrasonic driven scaler preferably performs a vibratory motion, which is triggered by an ultrasonic source, preferably incorporated in the handpiece 21. Such an ultrasonic source comprises piezoelectric elements, for example, and is controlled via the electronic supply or control line.The dental treatment device 100 further comprises a liquid container 50, for example a water container. In particular, it is provided that the liquid container provides liquid both for the powder gas jet unit 10 for forming the surrounding flushing liquid for the powder-gas mixture jet on the one hand and for the scaler tips for conducting the flushing fluid to the treatment zone of the scaler tips, i.e. the instrument tips 20.In particular, it is also conceivable for the handpieces 11, 21 to be replaceable or to be attached to the supply lines 14, 24 in a replaceable manner. Furthermore, the supply lines 14, 24 could be interchangeably connected to the base station 30 and / or the powder chamber 13.In addition, the dental treatment device 100 comprises a control unit 33, which is designed and defined for controlling the operating parameters of the scale 20 and / or the powder gas jet unit 10. For example, it is necessary to adjust the pressure supplied to the powder chamber 13 in order to generate the powder-gas mixture provided for the respective treatment. Further, the vibrational forces during treatment must be adjusted, as well as the performance of the ejected flushing fluid for the scale 20 and / or powder-gas mixture 10.Preferably, the dental treatment device 100 comprises a human-machine interface that allows a user to adjust operating parameters of the dental treatment device 100, preferably during treatment. As a result, it is possible, for example, to increase or decrease the intensity or power of the ejected powder-gas mixture jet, the ejected flushing liquid and / or the vibration movement of the scale tip 22, for example with regard to its amplitude and / or frequency. The human-machine interface 35 is provided, for example, as a command button and / or as a touchscreen integrated into the base station 30. It is also conceivable that the human-machine interface 35 is implemented via a Bluetooth connection or a wireless connection between the base station 30 and a mobile receiver with a display in order to adapt the operating parameters preferably during dental treatment.In Fig. 2, a schematic illustration of a second embodiment of the present invention is shown. The second embodiment substantially corresponds to that shown in FIG. 1, but does not use, for example, a clamping element 17 for attaching the powder chamber 13, so that in this version the gas inlet and the powder-gas mixture outlet are located or arranged in the base region of the powder chamber attached to the upper side of the base station, i.e. a corresponding coupling section adapted to the gas inlet and the powder-gas mixture outlet is integrated into the base. The base preferably forms a one-piece element which cannot be divided further without destroying it.Preferably, the control unit 33 is designed and defined such that it resets at least one operating parameter on the dental treatment device 10 for carrying out a dental treatment after and / or before a treatment cycle. This ensures that the same conditions are present at each start of the treatment cycle by a user. As a result, the user does not first have to check whether the last stored parameters could generate a use mode that is hazardous to the patient. For example, it might be critical to avoid the patient from feeling the force of the powder gas jet unit for supragingival treatment when the user starts subgingival treatment. This could damage the root of the tooth. If the user has forgotten the last state or parameter and simply starts the next treatment cycle, this could lead to unintentional incorrect operation of the dental treatment apparatus 100. At least the resetting of the operating parameters or the at least one operating parameter to the standard values makes an additional check before the treatment cycle superfluous or redundant. This is another approach than in the prior art, which has a control unit 33 that does not change the operating parameters during or between two treatment cycles.To trigger a reset of at least one parameter or a plurality of parameters or all parameters, a specific configuration or handling may be expedient. For example, it is conceivable that the handpieces can be attached to the base station 30, in particular to specific holding elements 19, 29. These holding elements 19, 29 are arranged, for example, on the sides of the base station 30 and serve for receiving the handpiece 11, 21 during a non-treatment mode. After the use of the scale handpiece 21 and / or the powder gas jet unit handpiece 11, the user, for example, clips or hangs the handpiece 11, 21 to the base station 30. To carry out such a triggering event, the holding element 19, 29 and / or the base station 30 can comprise a weight sensor or another detector which detects the presence or absence of the handpiece 11, 21 on the holding element 19, 29. This allows the user to reset the standard values by simply moving the handpiece 11, 21 back onto the holding element 19, 29. This is also advantageous in that no complicated reset is required at the machine interface, but the default values are automatically reset. This can be used by the user to quickly return to the parameters stored as reset values.Alternatively and / or additionally, the control unit 33 is designed and defined to set the operating parameter for the dental treatment during or after a cleaning mode. Such cleaning modes are preferably carried out regularly and repeated, for example, during a non-treatment mode, preferably in each non-treatment mode between two treatment cycles. These cleaning modes are intended to provide a clean powder gas device 10 and / or a clean scale 20, preferably for the next patient, so as to ensure that the correct settings for the patient are present at each start of the treatment cycle. Further, the user is informed that the cleaning mode has been performed.Additionally and / or alternatively, it is provided that the control unit 33 is designed and defined such that it resets the operating parameters when the tooth treatment device 100 is switched on and / or off. It can thus also be ensured that the correct settings are always present when the tooth treatment device 100 is restarted.Preferably, the operating parameters are non-zero. This also eliminates the need to change the operating parameter after starting the dental treatment device 100, and the user may instead immediately start treatment.Preferably, the operating parameter relates to a fluid pressure, in particular the liquid used for flushing for the powder gas jet unit 10 and / or the scale 20. Another operating parameter may be the pressure used to generate the powder-gas mixture in the powder chamber 13 and / or a power stage of vibration of this scale instrument tip. In particular, it is provided that the control unit 33 is designed and defined in such a way that it resets a set of operating parameters in such a way that a defined operation is automatically established or ensured for the scale 20 and the powder gas jet unit 20 when the user starts his dental treatment cycle.Reference Number:10 Powder gas jet unit 11 Handpiece 12 Nozzle element 13 Powder chamber 14 Supply line 17 Clamping element 19 Holding element 20 Scale 21 Handpiece 22 Instrument tip 24 Supply line 29 Holding element 30 Base station 33 Control unit 35 Human machine interface 50 Water container 100 Dental treatment deviceReferences included in the specificationThis list of documents cited by the applicant has been produced in an automated manner and is only included for the better information of the reader.
