Dental oven

An articulator having a maxillary member and a mandibular member, which are connected to each other via condylar articulations, wherein a maxillary adaptor is attachable or attached at the maxillary member and a mandibular adaptor at the mandibular member, wherein a maxillary alignment member especially is form-fittingly connected to the maxillary adaptor and a mandibular alignment member is especially form-fittingly connected with the mandibular adaptor, and wherein the alignment members are automatically alignable to each other and comprising scanning members, by means of which the arrangement of alignment members and adaptors is scannable in a scanner and especially the relative position thereof moreover is detectable in relation to the articulator via the scanner.

Articulator and articulator auxiliary device

Dental device

Methods for manufacturing a dental restoration for a patient and dental ceramics production devices are disclosed. A dental restoration may be designed based on a scan of the patient's mouth, using a CAD software module. The software module may produce conveyor channels for a positive model based on the dimensions of a muffle in relation to the size and shape of the positive model. The conveyor channels may extend at an angle of between 0&#xb0; and 130&#xb0; away from an axis of the pressing channel, the axis being located essentially along an isotherm inside the muffle. A docking site may be selected based on a position with the greatest wall thickness of the positive model. The present disclosure allows the creation of a high-quality dental restoration in a very efficient fashion, in particular when lithium disilicate is used as the dental ceramics material.

Process and device for manufacturing a dental restoration

The invention relates to a dental furnace wherein a firing chamber is heated up in a first heating-up period at a first heating-up rate of more than 501 K/min, in particular more than 1001 K/min, which heats the furnace to at least 10001 C., in particular to 1100-12501 C. The first heating-up period is followed by an intermediate heating period, which is at least five minutes long, in particular at least ten minutes long, the gradient or heating-up rate of which is adapted to the material to be sintered in the dental furnace (), and wherein this is followed by an end heating-up period () during which heating up is effected at a heating-up rate of more than 301 K/min, in particular approximately 501 K/min, and wherein during this the furnace temperature is held for at least five minutes, in particular for at least 25 minutes, above the temperature toward the end of the first heating-up period, and wherein forced cooling of the furnace () is performed after this.

Dental furnace

The invention relates to a dentel device for the treatment of a dental restoration part, comprising at least one operating program, a storage of the dental device and at least one detection device for at least one object. The detection device can detect data of the object and this data, in particular together with an operating program associated with the object, can be stored in a storage of the dental device or can be compared to the data of objects which have been stored in advance in the storage of the dental device. The dental device, depending on the comparison result of the data of a detected object with the data of objects which have been stored in advance in the storage of the dental device, starts the associated operating program or shows it for selection.

The invention relates to a dental furnace, in particular a firing furnace or press furnace, for firing or pressing a dental restoration part which is receivable in the furnace, possibly after pre-heating in a pre-heating furnace, and which is placeable on a base, in particular centrally thereon, wherein the dental furnace comprises a firing chamber whose diameter is larger than, in particular at least twice as large as, the largest dental restoration part to be fired, and which comprises a control device and an operating unit at the or for the dental furnace (), wherein by means of the operating unit () the size and/or the weight and/or the number of the dental restoration part(s) () to be fired or pressed is adjustable in units.

Occlusionom

A dental furnace having a display device and an operating device () for the dental furnace, is provided, the operating device being integrated in particular in the display device by forming a touch screen (), and the operating device () facilitating the selection of programs for the firing of dental restoration parts in the dental furnace. The operating device () allows in particular the input of further parameters for a firing cycle. An operating element () facilitates the control of a final firing program of the dental furnace, namely with different values for the temperature as well as for the duration of the final firing, the operating element () making possible the simultaneous adjusting of temperature and duration parameters of the final firing.

Dental furnace having a combined display and operating device

A process for manufacturing a dental restoration part as well as a dental furnace are provided in which the dental restoration part is produced on a foundation by means of applying at least two layers, wherein initial data, in particular three-dimensional data of the foundation, are stored in a memory device, and picture data, in particular three-dimensional data concerning the outer contour of the dental restoration part to be produced and the layers of the dental restoration part to be applied, are determined and in particular stored. It is provided that the dental restoration part is positioned at least partially during its production within the picture recording area of a picture recording device (), and that before finishing the dental restoration part () and upon the application of at least one layer, the latter is recorded at least with regards to the thickness of the layer and/or its color, is displayed in particular via a display device (). Furthermore, the layer recorded is compared with the picture data () at least regarding the thickness of the layer. An error signal is produced if the layer applied does not correspond to the predetermined layer in accordance with the picture data () regarding the thickness of the layer and/or the color and/or the other parameters.

Process for manufacturing a dental restoration part and a dental furnace for manufacturing the same

The invention relates to a dental furnace wherein a firing chamber is heated up in a first heating-up period at a first heating-up rate of more than 501 K/min, in particular more than 1001 K/min, which heats the furnace to at least 10001 C, in particular to 1100-12501 C. The first heating-up period is followed by an intermediate heating period, which is at least five minutes long, in particular at least ten minutes long, the gradient or heating-up rate of which is adapted to the material to be sintered in the dental furnace (), and wherein this is followed by an end heating-up period () during which heating up is effected at a heating-up rate of more than 301 K/min, in particular approximately 501 K/min, and wherein during this the furnace temperature is held for at least five minutes, in particular for at least 25 minutes, above the temperature toward the end of the first heating-up period, and wherein forced cooling of the furnace () is performed after this.
