An additively manufactured dental crown with a wall having a bottom edge and an occlusal portion joined with the wall opposite the bottom edge. The wall and occlusal portion form an interior surface and an opposing exterior surface. By using additive manufacturing and materials for such, the dental crown can have thin walls with a thickness of less than 300 microns at the thinnest portion of it and can include fine printed features such as identifiers, internal ribs, slots, porous meshes, and retention elements.

A method for producing a zirconia sintered body includes: heating a zirconia molded body or a zirconia pre-sintered body, the heating includes a temperature increasing step, and a rate of temperature increase in a temperature region from a temperature at which the zirconia starts to shrink to a temperature at which the zirconia finishes shrinking in the temperature increasing step is adjusted to enable the zirconia molded body or the zirconia pre-sintered body to shrink at substantially a constant rate during temperature increase in each of zones of when the temperature region is evenly divided into a plurality of zones of specific temperature ranges.

A method of making an all-zirconium one-piece dental implant has: oral scanning after implantation of artificial tooth roots, 3D archiving, making temporary dentures, and making integrated permanent dentures. The oral scanning is executed by an optical scanner and generates a digital file of a denture model, a five-axis processing machine makes a temporary denture according to the digital file of the denture model to provide fitting information to modify the digital file of the denture model or make a permanent denture. Making the permanent denture with an all-zirconium material without metal support comprises the five-axis processing machine forming a through hole in the permanent denture.

A dental bulk block for a CAD/CAM machining process. The dental bulk block is a glass-ceramic block having a crystalline phase embedded in an amorphous glass matrix. The crystalline phase includes lithium disilicate as a main crystalline phase, no sub-crystalline phase exists, and the crystalline phase has a mean grain size of 0.01 to 1.0 μm and a crystallinity degree of 25 to 45%. The dental bulk block can improve machinability during cutting such as CAD/CAM machining in the state of a high-strength workpiece with high flexural strength, thereby reducing a tool resistance and a wear rate, increasing a tool life span, and reducing edge chipping during a machining process. In addition, a dental restoration with desired translucency variations can be manufactured through a simple process of machining a block and altering post-heat treatment conditions, and thus can be realized with various shades.

The present disclosure provides methods, devices, systems, and computer-implemented methods for forming and placing attachments for use with dental appliances, and more particularly to the design, manufacture, and use of three-dimensionally printed attachment templates for use with orthodontic devices. Dental attachment templates include a cavity with one or more openings for injecting and bonding attachment material directly on a patient's tooth, which allow accurate placement of the attachments while providing the dental practitioner flexibility during the attachment forming process. Digital dental attachment template model techniques can be used to accurately place the cavity and opening.

A dental restoration system (1) for restoring a tooth at least during healing of an implant construction (5) being set into a jaw of a patient comprises a crown abutment (3) and a locking member (2). The crown abutment (2) is configured to be positioned on a gingiva former (4) mounted to the implant construction (5). The locking member (2) has a contact face (212) and a fixing structure (24) configured to be fixed to the gingiva former (4). The crown abutment (3) has a through hole (31) configured to receive the locking member (2) such that the contact face (212) of the locking member (2) contacts the crown abutment (3) and the fixing structure (24) at least partially extends out of the crown abutment (3). The crown abutment (3) is made of an abutment material configured to bond with a crown material used to build a crown (6).
