Definitions
- the invention relates to a digital impression taking method for producing a dental prosthesis.
- the invention also relates to an architecture of apparatus for the implementation of such a method.
- the term "dental prosthesis” must be understood in its most general sense. It relates to all kinds of prostheses proper, such as crowns, “onlay”, veneers, etc., as well as all other similar devices.
- the more recent processes implemented in the prosthesis laboratory although very efficient due to the technology used to scan the master models prior to the fabrication of the crown coping and machining according to the "CAD / CAM" processes, remain however dependent impressions made in the mouth by the dentist. They are not exempt, in whole or in part, from the drawbacks linked to these production steps.
- the invention sets itself the goal of a digital impression-taking process for the production of a dental prosthesis aimed at overcoming the drawbacks of the devices of the known art, and some of which have just been mentioned.
- the method according to the invention makes it possible in particular to no longer have to resort to fingerprinting by the dentist, and its plaster casting by the prosthetist, main sources of errors and requiring long re-iterations, and ultimately expensive.
- a digital radio fingerprint is taken using X-rays.
- the dental practitioner will be able to take digital impressions using either a medical scanner if they practice in a care establishment that has them. other purposes or a pseudo scanner (for example of the type marketed under the brand "NEWTOM 0 ", registered trademark).
- a medical scanner if they practice in a care establishment that has them. other purposes or a pseudo scanner (for example of the type marketed under the brand "NEWTOM 0 ", registered trademark).
- a pseudo scanner for example of the type marketed under the brand "NEWTOM 0 ", registered trademark.
- Such a device can be installed in a room with typical dimensions 3 x 3 meters, or even less. As a result, it can be installed in most dental offices. More generally, use will be made of a scanner-type X-ray generator, that is to say making it possible to obtain a tomography.
- a digital data processing system with a recorded program advantageously cooperates with specialized prosthesis design software and receives the aforementioned digital files. This makes it possible to design the prosthesis sought and controls the machine tool for the manufacture of the prosthesis. This can be indifferently, as has been indicated, a metal crown, a mono-colored ceramic crown, a mono-colored facet, an "onlay", etc. These prostheses can be sent directly to the dentist.
- the radiographs are completely reproducible and the quality of the radiography does not depend on the person who took it. It should also be added that the doses of X-rays are, taking into account the technology used and the acquisition times of the order of a few seconds, completely harmless for the patients.
- the main object of the invention is therefore a method of taking an impression in an area included in the maxillofacial sphere of a patient for the production of a prosthesis and / or a device called "master model", characterized in that said fingerprint is a radio-digital fingerprint made using an X-ray generating apparatus and in that it comprises at least subsequent steps for generating a digital data file from said fingerprint and production, based on said data contained in said digital file, of said prosthesis and / or of said "master model” device.
- the invention also relates to an architecture of apparatus for the implementation of this method.
- FIG. 1 very schematically illustrates the main steps of the digital method of taking an impression and producing a dental prosthesis, according to one mode preferred of the invention, and shows the distribution of tasks between a dental office in which the impression is taken and a laboratory of dental prostheses in which the production of the prosthesis is carried out.
- the first step consists in taking a radio-digital imprint of the oral cavity of patient P, once the so-called "mouth care” work is finished.
- the digital radio print can be performed by a dentist or his dental assistant (not shown in the figure). It is carried out using an X-ray generator, under the general reference 1, of the medical scanner type or of the so-called “pseudo-scanner” type, as previously indicated.
- X-ray generator under the general reference 1, of the medical scanner type or of the so-called "pseudo-scanner” type, as previously indicated.
- Such devices are well known per se. They are used in other areas of medicine. It is therefore unnecessary to describe them further.
- the patient must go to an annex room in which the X-ray generator 1 is located.
- the second step includes the generation of a digital file 2.
- a digital file 2 is generated at the output of the apparatus 1 X-ray generator, file on which appear teeth prepared, for example for installation a crown, preferably on a scale of 1 - 1.
- the digital file 2 thus constituted is transmitted to the dental prosthesis laboratory or more generally to a center for manufacturing such prostheses, under the general reference LPD. he can be transmitted in various modes and in particular in the two main modes below.
- a first possible mode of transmission is the telematic way, in the general sense of this term: modem, transmission by a local network, by an Internet network or by an intranet network connecting dental offices and one or more laboratories of dental prostheses, etc. .
- This mode of transmission has been symbolically represented by the general reference It.
- the file is firstly recorded on a physical medium: floppy disk, tape, CD-ROM (read-only, for example of the "CD-R” type, or rewritable, for example of the "CD-RW”), etc.
- the recorded medium is transmitted by conventional channels: mail, carrier, etc.
- This mode of transmission has been symbolically represented by the general reference D.
- the file 2 is received by a telematic transmission line T connected to a microcomputer 3, or, more generally, to a digital data processing system with recorded program, via a modem 30 for example.
- the microcomputer 3 can process the data received, that is to say the file 2, immediately or store them for later use in a mass memory 31. It also includes various conventional organs, both internal (processor, etc.), as external (various peripherals such as screen, keyboard, mouse, etc.).
- a recorded support reader symbolized by a floppy drive 32.
- the latter is used in particular for reading the file 2, when it is recorded on a medium D.
- the microcomputer 3 can record one or more specific program (s) in the form of specialized design software (s). prosthesis, advantageously on a hard disk: mass memory 31.
- programs for converting file formats are also implemented in the microcomputer 3. These programs make it possible to convert, as necessary, the initial format of the file 2 received, in a format suitable for the order of machine tools which will be specified below.
- the first case concerns a prosthesis that will be called "aesthetic" or intended for the anterior sector (teeth participating in the smile) of a patient to be treated.
- a screed, metallic or ceramic is first made. This clevis thus produced is taken care of by the prosthetist (not shown) who personalizes one or more permanent teeth. This is done by laying ceramic, by modeling it, by a gradation of color, by rendering a certain saturation and a certain luminosity. This step is symbolized by the reference 6 (manual processing) in Figure 1.
- the second case concerns a prosthesis that will be called "non-aesthetic" or intended for the posterior sector of the mouth of a patient to be treated.
- the prosthesis can be definitively manufactured by machining (machine tool 5) and sent directly to the dentist sending the radio-digital files 2. In this case, there has been almost no human intervention since taking the radio impression. digital (1 x-ray generator device) until the crown is produced.
- the method according to the invention also remains compatible with the traditional working methods of a prosthesis laboratory. For prosthetists who wish to continue working artisanally according to a "master model” and develop the screed and any finishes themselves, it is possible, upon receipt of the radio-digital files 2, to make a master model by stereo-lithography.
