An intraoral device includes a shell form including a top surface, a bottom surface, an arcuate anterior edge, a posterior edge and a nominal depth between the top and bottom surfaces thereof, an arcuate channel formed within the shell form along the anterior edge, open at the top surface, the channel including dental impression material enabled by process to accept a plurality of maxillary anterior teeth of a user forming a mold, a bottom plate assembled to the bottom surface of the shell form may be interchangeable, the bottom plate conforming to the peripheral shape of the shell form, the bottom plate hosting at least one incline angle on the bottom surface thereof.

Systems and methods for providing oral devices using at-home dental impression kits are disclosed herein. An example method includes scheduling an at-home dental impression kit to be sent to a user that includes at least (i) one or more dental trays and (ii) one or more sets of dental putty that are configured to capture the gingiva of the user without distorting the gum lines of the user. The example method further includes scanning a first impression that is representative of the user’s upper jaw, and a second impression that is representative of the user’s lower jaw. The example method further includes generating a digital rendering of an oral device, and uploading the digital rendering to an application for viewing by the user. The example method further includes fabricating the oral device based upon digital rendering, and scheduling the oral device to be sent to the user.

The invention relates to an automatic stirrer for mixing dental cast materials. The automatic stirrer comprises a mounting frame, a water supply mechanism, a plurality of first water tanks and a driving motor, wherein the water supply mechanism, the first water tanks and the driving motor are mounted on the mounting frame, and the water storage amount of the first water tanks can be regulated and controlled; the first water tank regulates and controls the water storage amount in the first water tank through an electronic water level control switch or a sealing plug arranged in the first water tank; a sealing plug through hole of a conical structure is formed in the center of the sealing plug, a spherical blocking floating ball capable of floating upwards and blocking the sealing plug through hole is installed in the sealing plug through hole, and a water valve is further arranged on the first water tank. The automatic quantitative water supply device can realize automatic quantitative water supply and is convenient to use.

To solve the following problem, in which scanning a cast dental model may result in missing crucial areas of detail which may be more readily visible in the dental impression, for example, areas of detail in the interproximal regions and the retracted gingival sulcus around a crown preparation may not be captured accurately, conversely, regions which may be difficult to accurately scan in a dental impression may be more readily visible in the cast model.SOLUTION: A three-dimensional scanning method includes the steps of: a region for replacement in a first point cloud of a dental object; and patching the region for replacement with a corresponding region from a second point cloud of a dental object.SELECTED DRAWING: Figure 12

A device for use in producing a dental impression is disclosed. The device has a material receiving region into which dental impression material is received in use. The material receiving region is shaped to fit over an upper and a lower dental arch of a person. The device also has a base which forms the bottom of the material receiving region, an outer wall forming an outer side of the material receiving region, an inner wall forming an inner side of the material receiving region, and a region of open space which is partially surrounded by the inner wall, except that the region of open space has an open end / side towards rear of the device. The height of the inner wall relative to the base is less than height of the outer wall relative to the base.
