The medical team in Sofia, Bulgaria, has more than 15 years of experience with immediate load implants and has received numerous rewards and recognition. Dental implant Dental implants are the best solution to replace one or more missing teeth. It gives natural look to the dentition and integrates perfectly in your mouth. Dental implant is made from titan, which is a perfectly biocompatible and solid material.
The object of the invention is a method for producing and compliance control of a dental prosthesis from an outlet mouth parameters with a color imaging device, characterized Resultat cap prothesiste dentaire marseille that it comprises the following steps: The present invention relates to a method for producing and compliance control of a dental prosthesis from an outlet mouth parameters with a color imaging device.
We know that the denture manufacturing are performed by technicians who are not necessarily close to the dental practitioner or are produced in industrially oriented units in highly geographically distant from the place of installation country but the labor costs of out are lower. The prosthesis thus produced remotely, is sent by mail to the dental practitioner and it is necessary to deliver a prosthesis that is not only suitable dimensionally, this not being the object of the present invention, but also perfectly suited aesthetically.
It was in fact essential for a prosthesis: The hue at large is paramount and additional information can achieve optimal results. This is where the problems arise because it is necessary to determine not to only subjectively settings but also through actual measurements, repeatable, verifiable.
Then, once these parameters determined, we need to check that the aid complies with these settings once manufactured, so as not to deliver a prosthesis that would be inappropriate.
Poor workmanship resulting in significant costs as it takes: It is imperative to ensure upstream quality control installation, from the production, a certainty for the practitioner to receive a ready prosthesis to ask, established limits during the shade-taking.
The first difficulty is precisely the shade taking. The tooth shade and matches the color of the tooth, that is to say, brightness, saturation, hue but can also incorporate any parameter that affects the appearance of the tooth as translucency or transparency, or yet its surface condition.
When carrying out a dental prosthesis, Resultat cap prothesiste dentaire marseille is necessary that this prosthesis resume the same colors as the neighboring teeth or as close as possible to go unnoticed in the patient's mouth. According to a known technique, evaluating the shade of a tooth can be done visually by a dentist.
The dentist performs the shade taking for the realization of the dental prosthesis by comparing the patient's tooth and reference teeth of a color chart. Tints thus determined, are then provided to a technician to enable the latter to select mixtures of pulp used in the manufacture of the corresponding prosthesis.
Cette technique de mesure est peu fiable. This measurement technique is unreliable. The appreciation of the colors of a tooth is subjective and can vary from one practitioner to another because of the perception of the eye mechanism.
This measure is also influenced by environmental factors such eg lighting conditions. To overcome the practitioner's perception errors, a more objective evaluation can be performed using a spectrum analyzer of a tooth subject to a light beam.
Such a device comprises a handle and a measuring head contacting the tooth to be measured, the measuring head being connected to the transmission-reception means by a bundle of optical fibers. The handle comprises a light source such as light emitting diodes LEDs and the measuring head comprises light sensors.
However, this device can only perform one-off measures on the tooth. According to another embodiment, it is also possible to use an imaging device for performing a mapping of the tooth.
The captured image is then subjected to image processing such as automatic segmentation to determine a set of characteristics of the tooth.

Such a shooting device comprises a measuring head and a handle. The head includes at least one image sensor, an optical system and an LED lighting system for illuminating the shooting area.
Although it allows to carry out a two-dimensional measurement, this device has a relatively bulky measurement head. Another drawback of these known devices is related to the fact that the measuring head remains fixed relative to the handle. Therefore the use of these devices is limited to a front portion of the patient's dental arch.
Also, even though the devices of the prior art can be used for carrying out the method according to the invention, the apparatus described below for carrying out the method according to the present invention achieves a better result. This system aims to overcome the disadvantages of the prior art by providing a device with a very compact measuring head to perform a two-dimensional analysis, while having access to all the teeth in the mouth.
The method of making and control is particularly optimized. For this purpose, the dental shade measuring apparatus includes a housing, a handle and a measuring head, said measuring head includes: According to one embodiment of the apparatus, the set of orientation comprises at least a first half-shell capable of being joined to a second half-shell to form a hollow shell defining a cavity configured to receive said proximal end, said cavity having on its inner surface a surface radially projecting intended to cooperate with a plurality of housing having a complementary shape formed on the outer surface of the proximal end for the different angular positions of the measuring head relative to the housing.
Advantageously, the set of orientation comprises a locking means for locking the measuring head in a defined angular position relative to the housing. It is therefore understandable that the shade determination focusing on the patient's tooth and limiting the interaction of adjacent teeth, is freed from the impact of the entire environment of the affected tooth.
Other features and advantages of the process according to the present invention appear from the following description of particular embodiments, given as nonlimiting examples, and the description of the device used, this with reference to the accompanying drawings, in which: These measures can achieve complete and precise mapping of changes in various characteristics of the tooth.
In particular, this mapping determines the tooth shade for the realization of a dental prosthesis according to the process of the present invention. The apparatus includes a handle 10 graspable surmounted by a housing 11, one end of the housing 11 being provided with a measuring head 20 for acquiring spectral data or images.Jan 04, · 7 posts published by hannahkawaii during January Produit Dentaire.
