Embodiment Construction

[0017] Referring to Fig. 1, this method is generally suitable for manufacturing multiple elements for filling damaged parts of mammalian teeth.

[0018] In order to implement this method, a model for filling one or more defective parts of one or more dental organs must first be constructed. This model can be realized by two methods, which can be made directly in the mouth, namely Method A; it can also be used by conventional materials (alginate, silicone or other materials) to create a dental model for the defect part in the denture maker’s Manufactured in the laboratory, method B. This dental model will be processed in the laboratory of the denture maker in order to obtain a positive model.

[0019] In the first method A, the dentist uses a grinder or a hole punch to remove the insufficient tooth tissue in operation step 1 in order to repair and define a new solid 2 defined by healthy tissue, which has a dial out oblique Degrees of wall shape. So far, what needs to be done is to ...

Abstract

The invention relates to a method for producing high-geometric precision elements made from a neutral material. Using different types of prosthetic restoration, said elements are intended to fill the damage caused in teeth by dental caries or tissue alteration having other causes. The inventive elements are also intended to be used to produce high-precision dental crowns or other related dental devices. The method is characterised in that: a model (10), which is designed to fill the missing dental tissue that has been destroyed, is made either in vivo, updating and defining a new volume (2) that is bordered by healthy tissue and having a tapered wall, or in vitro, taking an impression in the mouth of a dental preparation using an impression compound, said impression then being cast in plaster, and updating and defining a new volume (2) using said positive plaster model; the measurements of said model (10) are then taken in 3D using a three-dimensional measuring apparatus (4, 15, 17) with light wavefront analysis and volume analysis which is carried out using shots, a projector (15) being positioned at an angle to a camera (17) and said projector (15) and camera (17) being mechanically and geometrically linked to a revolving platform (18) that is used to support the model by means of a frame (19) in order to obtain good triangulation; the data are processed electronically (12) to remodel the morsels of volume; the files are subsequently modified electronically to determine exactly the desired profile; and the final element to be implanted is machined with a digitally-controlled machine (6, 23, 24, 22).

Description

Technical field [0001] The present invention relates to a method for manufacturing an inlay made of neutral materials with very accurate geometric dimensions. The inlay is used to fill the damage caused by the hard tissue of the tooth by inlay or mounting, or to use a large Accurate manufacturing of part or all of the crown, or other inlay devices that are measured in vivo by a denture manufacturer, or are based on wax molds, resin molds, or other plastic material molds. Background technique [0002] In the field of dentistry, there are currently a variety of methods and mechanical devices that are used to fill the tooth tissue material defects in the tooth crown or other parts due to tooth decay or other reasons. [0003] At present, for dental caries or dental tissue decadence, in order to suppress dental caries and decadence, dentists use a grinder or a hole punch to remove the damaged part, and make a cavity through the above-mentioned equipment, or prepare in the cavity Fill...
