The model is secured by closing the arms. Thus, heat from the laser need only elevate the temperature slightly to cause sintering, greatly speeding the process. Excess powder is simply brushed away and final manual finishing may be carried out.

Light back-scattered by the sample passes a second time through the object arm and is guided towards the single mode directional coupler DC2 via DC1 where it interferes with that coming from the reference arm. Frameworks for fixed partial denture made out of dental alloys through classic techniques currently involve many errors like marginal and internal gaps due to temperature contractions Fig. We apply the Gypsum paste on the basic side of the model and the articulators arm for its assembling in the articulator.

The ACCU-TRAC eliminates the tennice which need a more laborious technology for the obtainment of models with mobile dental dies, being indicated in the fixed and composed prosthetics. Masters, Three-dimensional confocal microscopy of the human optic protezatii in vivo, Opt. Axial extensions of the preformed crown should replicate, as closely as possible, dimensions and contours of the original tooth form.

A transversal resolution better than 5 microns is obtained in the OCT channel. After the denture is fully formed, the piston is raised to elevate the object. We remove the model from the support with the overturned white base plate, with the central ribs upside. Fujimoto, Optical coherence microscopy in scattering media, Opt.

The marginal fit of the fixed partial dentures can be investigated especially by microscopic devices that are very hard to use in oral cavity. The component parts are washed, dried and reassembled in the support in numerical line.

The working model with mobile and detachable parts can be classified as follows: Simulatoarele aparatului dento-maxilar by Dorin Bratu Book 1 edition published in in Romanian and held by 2 WorldCat member libraries worldwide. No supports are required with xlinice method since overhangs and undercuts are supported by the solid powder bed. Large parts with thin sections may require as much as two days of cooling time.

Also the microscope can reveal only the surface problems of adaptation. The space maintainer of green colour is applied on protezari basic side of the support. Amprenta si modelul in proteza fixa by Dorin Bratu Book 1 edition published in in Romanian and held by 2 WorldCat member libraries worldwide.

Both output fibers from DC2 are connected to two pin photo-detectors in a balanced photo-detection unit. A nitrogen atmosphere is also maintained in the fabrication chamber which prevents the possibility of explosion in the handling of large quantities of powder.

The configuration of the second system, prtezarii shown in Fig. Jackson, Coherence imaging by use of a Newton fehnice sampling function, Optics Letters, 21 21, 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. The powder supply system is similar in function to the build cylinder. Sectioning of the mobile dental dies. In this case the piston moves upward incrementally to supply powder for the process.

Bratu, Dorin Overview. Help Center Find new research papers in: Using cervico-incisal scanning it was possible to investigate the marginal fit of the fixed partial dentures to the pillar teeth.

The image in a is the magnification of the area of marginal adaptation in the proximal zone, slice 5 from 94; b represent the slice 15 from 94, zoom, 8 degree in air scanning of the same sample. An inferior face is provided with ribs which serve at the removal of the model from the main device.

Studies on the Importance of Metal-ceramic Bond in Merging Ceramic Mass on Metal Component

En-face OCT images from different metal-ceramic, integral ceramic fixed partial prostheses and implant mezzo structures are shown.

Two en-face OCT systems have been used. 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. The image in a is the magnification of the 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.

Polymer – acrylic tehniice – polyurethanic resins; – epoxydic resins; – epiminic resins. It has a canal with embattled border and a rib with numbers from 1 to 59which permit the reattachment of the sectioned segments from the working model the mobile dental die The space retainer is made out of semi-rigid and the other components of the prosthetic field into the green material, which is adapted to the main device base support of a unique position.

Heat clijice the laser melts the powder here it strikes under guidance protezaii the scanner system.

The image in R is the magnification of the area in the bottom of the image L. Bazele clinice si tehnice ale protezarii fixe Book 2 editions published between and in Romanian and held by 3 WorldCat member libraries worldwide.

The ACCU-TRAC system is an efficient one fast and cheap and precise in the accomplishment of models with dental dies which eliminate the pines, being indicated in fixed and composed prosthetics. Through this technique can be produced up to 80 pieces in only one step. Systems which permits the obtainment of mobile dental dies without swivel: Bazele clinice si tehnice ale protezarii edentatiei totale Book 2 editions published between and in Romanian and held by 4 WorldCat member libraries worldwide.

No final curing is required as in stereolithography, but since the objects are sintered they are porous. The side arms are made of plastic material, allowing the entire fixing of the mobile dental dies and prptezarii.
