Embodiment Construction

[0076] The following description provides an example of how the invention may be applied to make an implant-supported dental bridge. It should be understood that an implant-supported dental bridge is a specific type of dental restoration which, in use, is secured to a plurality of dental implants already placed in the patient's jaw, thereby retaining the dental restoration in the patient's mouth. Typically, implant-supported bridges are used to replace multiple teeth. Implant-supported bridges are typically made from a metal base structure to which porcelain veneers are added prior to assembly to give the bridge the desired finished shape and appearance. The basic structure of a bridge is often referred to as the "framework" or "superstructure".

[0077] It should be understood that the present invention is not limited to the manufacture of implant-supported bridges, but may also be used, for example, in the manufacture of other types of dental restorations, such as single-to...

Abstract

A method of manufacturing an article, comprising taking an article formed in an initial state via an additive manufacturing process and performing a second manufacturing process to transform the article into a second state, which comprises mounting the article in a holding device, processing at least one first feature on the article, which comprises processing at least one set of mounting features on the article, re-mounting the article via the at least one set of mounting features, and then processing at least one second feature on the article.

Description

technical field [0001] The invention relates to a method for producing an article, for example an article comprising at least one dental restoration. Background technique [0002] Rapid manufacturing techniques are becoming more widely used to produce a variety of parts. In particular, the technique of building parts layer by layer is becoming more widely known and used industrially to make custom parts. Selective laser sintering is one such rapid manufacturing technique whereby articles can be built layer by layer from powdered materials, such as powdered metals. For example, a layer of powder material may be applied to the bed of a laser sintering machine, and the laser directed to sinter or melt selected portions of the powder material to form the first layer of the part. Another layer of powder is then coated on top and the laser is again directed to sinter or melt another layer of the part. The process is repeated until the entire part is formed. The formed part is ...
