Two en-face OCT systems have been used.

Digital Dentistry — Digital Impression and CAD/CAM System Applications

Podoleanu, Mike Huighes, Philippe Laissue, Cezar Clonda – Optical Coherecte Tomography as a non invasive method used in ceramic material defects identification in fixed partial dentures, Dental Target, nr. Heat from the laser melts the powder here it strikes under guidance of the scanner system. Through this technique can be produced up to 80 pieces in only one step. No final curing is required as in stereolithography, but since the objects are sintered they are porous.

The detection of these marginal adaptation problems allows all the corrections in order to avoid the failure of the prosthetic treatment. Simulatoarele aparatului dento-maxilar by Dorin Bratu Book 1 edition published in in Romanian and held by 2 Protezarij member libraries worldwide. En-face OCT images from different metal-ceramic, integral ceramic fixed partial prostheses and implant mezzo protezraii are shown. A parallel between the classic casting technique and this new technology reveal the least has several advantages: After the detection of the materials defects the numerical simulation method was used in order to estimate the effect of the masticatory forces on the fractures propagations in the ceramic materials.

Log In Sign Up. The image in R is the magnification of the area in the bottom of the image L. The image in a is the magnification of clinicr area of marginal adaptation in the vestibular zone, slice 23 from 94; b represent the slice 44 from 94, zoom, 8 degree in air scanning of the same sample.

Express, 3,http: Amprenta si modelul in proteza fixa by Dorin Bratu Book 1 edition published in in Romanian and held by 2 WorldCat member libraries pfotezarii. The second system, equipped with a confocal channel at nm, uses a high NA interface optics allowing clinife mm image size. Bratu, Dorin Overview.

Axial extensions of the preformed crown should replicate, as closely as possible, dimensions and contours of the original tooth form. On the both sides of the during the assembly into the articulator. The Gypsum in excess will be removed before it becomes harder. After the denture is fully formed, the piston is raised to elevate the object. The conformer is made of Plexiglas.

The centring of the impression over the main device, applied over the base plate. Poor marginal adaptation of the metal ceramic fixed partial denture that can lead to secondary cavities to the pillar teeth. C-scan images from a integral pressed ceramic crown at two magnifications. The powder supply system is similar in function to the build cylinder. Remember me on this computer. When the Gypsum becomes harder, we remove the impression, the basic plate and the side arms are opened.

It also comprises a cylinder and piston. It has 2 faces: Excess powder is simply brushed away and final manual finishing may be carried out. With a blade or a special device type MODEL-CUT for sectioning, we remove the excesses of Gypsum, we divide the mobile dental dies which are parallel to the milled edges. Positional accuracy of four die tray systems J Prosth Dent ; Both output fibers from DC2 are connected to two pin photo-detectors in a balanced photo-detection unit.

The component parts are washed, dried and reassembled in the support in numerical line. The model has a base which The traditional physical and analogous working permits its assembly into a simulating intermaxillar model is cliice through different technologies in the instrument. Using fehnice scanning it was possible to investigate the marginal fit of the fixed partial dentures to the pillar teeth. The space maintainer of green colour is applied on the basic side of the support.

In this case the piston moves upward incrementally to supply powder for the process. We apply the Gypsum paste on the basic side of the model and the articulators arm profezarii its assembling in the articulator. The marginal fit of the fixed partial dentures can be investigated especially by microscopic devices that are very hard to use in oral cavity. Simulatoarele ADM si principiile functionale ale ocluziei: Thank you for your participation!

Classification of the working model with mobile detachable dental dies: This saves some finishing time compared to stereolithography. Podoleanu, Fast scanning transmissive delay line for optical coherence tomography, Opt.

Help Center Find new research papers in: The impression is washed, dried, the borders in excess will be reduced; we mark on the posterior side of the impression, the middle of the crests in the posterior region and the median line in the frontal zone. Much progress has been made over the years in improving surface finish and porosity. The model from the support. Restaurarea dintilor devitali by Dorin Bratu Book 1 edition published in in Romanian and held by 2 WorldCat member libraries worldwide.

The configuration of the second system, as shown in Fig. It may take a considerable time before the part cools down enough to be removed from the machine. A computer driven translation stage TS is used to construct B-scan images by stopping the frame scanner and moving TS along the optical axis of the reference beam.

Light from the SLD source is injected into the system via the directional coupler DC1 which splits the light towards the two arms of the interferometer, the probing and the reference arm respectively.

Polymer – acrylic resins; – polyurethanic protezarik – epoxydic resins; – epiminic resins.
