Problems solved by technology

[0005] Although the method described in the '154 patent can be used to manufacture high quality dental restorations, the method may still be suboptimal in some situations
In particular, since most restorations are curved to some extent, using a square frame can be a waste of resources
Additionally, the square frame of the '154 patent may not permit machining in all areas and / or from all angles required for some applications
Also, in some cases it may be difficult to fit the screws into the desired position during the installation of the restoration

Embodiment Construction

[0037] figure 1 , figure 2 with image 3 Shown are various dental devices 10 that may be manufactured by an exemplary system 12, described at Figure 4 shown in and described in detail below. Figure 1 to Figure 3The dental device 10 can be made of any type of material to have any desired shape. For example, the dental device 10 may be made of a metal such as titanium, titanium / aluminum / vanadium alloys, titanium / aluminum / niobium alloys, titanium / zirconium alloys, cobalt / chrome alloys, or other similar alloys. It is also contemplated that the dental device 10 could alternatively be made of a non-metallic material, such as ceramic, plastic, or a composite material, as desired. Dental device 10 may include, inter alia: superstructure (eg, bridges, crowns, dentures, and other restorations) 14; substructure (eg, abutments, rods, implants, screws, and other similar structures) 16, The structural configuration provides seating for the superstructure 14 ; and a template (eg, dri...

Abstract

A workpiece is disclosed for use in making a dental device. The workpiece may have a ring-shaped frame, and a base form of the dental device additively manufactured inside the ring-shaped frame. The workpiece may also have at least one connector extending between the base form and the ring-shaped frame.

Description

technical field [0001] The present disclosure relates generally to a manufacturing system, and more particularly, to systems and methods for manufacturing dental devices including restorations, support structures, and drill holes or surgical templates, and to dental devices and the use in manufacturing dental devices artifacts. Background technique [0002] Additive manufacturing is the process of creating three-dimensional parts by depositing overlapping layers of material, usually under computer-guided control. One additive manufacturing technique is known as direct metal laser sintering (DMLS). DMLS technology uses a laser to direct a high-energy beam into a medium of powdered metal at precise locations that correspond to the features and dimensions of the part to be manufactured. When the energy beam contacts the powdered metal, it causes the powdered metal to melt and weld together and to the previously melted layers of the part. [0003] In some cases, parts created...
