Embodiment Construction

[0017] Referring to Figure 1, the method is generally applicable to the manufacture of a plurality of elements for filling damaged mammalian teeth.

[0018] In order to carry out the method, it is necessary first to construct a model for filling one or more missing parts of one or more dental organs. This kind of model can be realized by two methods, it can be made directly in the mouth, that is, method A; it can also be made with the help of conventional materials (alginate, silicone or other materials) to make a tooth model for the defective part, and then in the denture maker's Prepared in the laboratory, namely Method B. This dental cast will be processed in the denture maker's laboratory in order to obtain the positive cast.

[0019] In the first method A, the dentist removes incompetent tooth tissue by means of a grinder or a hole punch in operation step 1 in order to repair and define a new volume 2 bounded by healthy tissue, which has a pull-out angle. degrees of wal...

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 invention relates to a method for the manufacture of inlays made of neutral material and of very precise geometrical dimensions, which are used for filling damages caused on the hard tissue of teeth by setting or mounting, or for filling Precision manufacturing of partial or complete crowns, or other inlay devices by a denture maker by measurements made in vivo, or based on measurements made with wax or resin or other plastic material models. Background technique [0002] In the field of dentistry, there are currently various methods and mechanisms for filling the loss of tooth tissue material in the crown or other parts of the tooth due to dental caries or other reasons. [0003] At present, for caries or decay of tooth tissue, in order to inhibit caries and decay, dentists use a grinder or a hole puncher to remove the damaged part, and make a cavity through the above instrument, or prepare in the cavity Filling into a plastic material: mercury- ...
