Systems and methods for securing artificial teeth to a dental prosthetic base with a gradient polymer are disclosed herein. An example system includes one or more processors and a memory communicatively coupled with a 3D printing device and the one or more processors. The memory stores a set of instructions thereon that, when executed by the one or more processors, cause the one or more processors to: generate a print file representative of a polymeric dental prosthesis, the print file including (i) a first material, (ii) a second material that does not chemically bond with the first material, and (iii) a gradient transition zone bonding the first material to the second material that is a gradient polymer of the first material and the second material; and print, via the 3D printing device, the polymeric dental prosthesis based on the print file.

A device comprising; a controller arranged to receive data for an article to print; a sub-device comprising a resin source arranged to provide material for printing the article; a radiation source arranged to direct radiation for the printing of said article; a plurality of stations, said stations including a printing tank in which the article is printed, at least one cleaning station for cleaning the printed article and a curing station arranged to at least partially complete the curing of the printed article; a build surface upon which the article is arranged to be printed; wherein controller is arranged to move the build surface and the plurality of stations relative to each other.

A system for forming a product with different size particles is disclosed. The system comprises at least one print head region configured to retain a first group of print heads configurable to additively print at least a first portion of the product with a first material and a second group of print heads configurable to additively print at least a second portion of the product with a second material. The described system may also comprise a processor configured to regulate the first group of print heads and the second group of print heads to distribute the first material and the second material. A method of making an object by ink jet printing using the disclosed system is also disclosed.

A method of producing a dental object (100), including the steps of producing a pillared support structure (101) on the dental object (100); and producing a lattice structure (103) for reinforcing the support structure (101).

A method for directly printing orthodontic and dental appliances on the teeth of a patient. The tooth is scanned with a scanner which is communicated with a computer controller configured to recognize the anatomy of the tooth. The surface of a tooth of the patient is then prepared in order to receive the type of appliance designated for the patient. Using image data from the print head, the computer controller prepares a three-dimensional blueprint or design of an appropriate orthodontic or dental appliance. The computer controller controls the type and amount of material that is distributed through the print head only when the print head passes over the recognized anatomy so as to directly print the corresponding appliance onto the tooth layer by layer as the print head makes successive passes over the surface of the tooth.

The invention relates to a computer-implemented method for providing a template for a casting matrix configured for casting one or more artificial gingiva parts of a removable denture. The casting matrix comprises one or more recesses. Each of the recesses has a 3D geometric form, which is a negative of a 3D geometric form of a section of the removable denture with one of the artificial gingiva parts to be casted.

Systems and methods for orthognathic surgical planning are described herein. An example computer-implemented method can include generating a composite three-dimensional (3D) model of a subject's skull, defining a primal reference frame for the composite 3D model, performing a cephalometric analysis on the composite 3D model to quantify at least one geometric property of the subject's skull, performing a virtual osteotomy to separate the composite 3D model into a plurality of segments, performing a surgical simulation using the osteotomized segments, and designing a surgical splint or template for the subject.

The present invention relates to a method of producing a dental object (100), comprising the step of producing a support structure (101) on the dental object (100) having a predetermined breaking point (103) arranged such that a residual portion (105) of the support structure (101) remains on the dental object (100) after the predetermined breaking point (103) is separated.

An artificial tooth molding apparatus comprises: a calculation control unit (10) configured to calculate and convert 3D graphic data (D_g) required for a process of molding an artificial tooth into continuous tomographic data (D_1) and to output the tomographic data (D_1); an elevation means (20) configured to form the artificial tooth (T); a tank (30) containing the ceramic mixture solution (S) provided for immersion of the formation stage (22) of the elevation means (20); an irradiation means (40) configured to irradiate the formation stage (22) with ultraviolet rays; and a filter part (50) configured to filter an ultraviolet irradiation area irradiated with the ultraviolet rays.

In some embodiments, systems, apparatuses, and methods are provided herein useful to orthodontic systems. In some embodiments, an orthodontic system comprises a carrier structure comprising a base, a plurality of groups of support structures, a plurality of orthodontic appliances associated with one of the plurality of groups of support structures, and at least one rail extending from the base, and an assembly structure comprising a body, a plurality of complementary pieces associated with one of the plurality of orthodontic appliances, at least one channel configured to interface with the at least one rail to allow the assembly structure to be moved from a first position to a second position with respect to the carrier structure, wherein movement of the assembly structure with respect to the carrier structure causes the plurality of complementary pieces to mate with the plurality of orthodontic appliances.
