Bratu, Dorin 1942-
Help Center Find new research papers in: The second system, equipped with a confocal channel at nm, uses a high NA interface optics allowing 1 mm image size. 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 entire fabrication chamber is sealed and maintained at a temperature just below the melting point of the plastic powder. Bazele clinice si tehnice ale protezarii edentatiei totale Book 2 editions published between and in Romanian and held by 4 WorldCat member libraries worldwide.
The model is secured by closing the arms.
On the working model, we will make the template of the future prosthetic part. Assembling the models in the articulator. C-scan images from a metal-polymer veneer crown at two magnifications. C-scan images from a integral pressed ceramic crown at two magnifications. The ACCU-TRAC eliminates the pins which need a more laborious technology for the obtainment of models with mobile dental dies, being indicated in the fixed and composed prosthetics.
The probing beam is reflected by the dichroic beam-splitter BS1 and then sent via the galvanometer scanners SX and SY to the sample.

Podoleanu, Fast scanning transmissive delay line for optical coherence tomography, Opt. Both use similar pigtailed super-luminescent diodes SLD emitting at nm and having spectral bandwidths of 65 nm which determine an OCT longitudinal resolution of around Metal – on the galvanic base; – easy fusionable alloys; – melted and pulverized alloys; – amalgam.
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.
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. Bazele clinice lcinice tehnice ale protezarii fixe Book 2 editions published between and in Romanian and held by 3 WorldCat member tehnkce worldwide.
Systems which permits the obtainment of mobile dental dies without swivel: Much progress has been made over the years in improving surface finish and porosity.
Digital Dentistry — Digital Impression and CAD/CAM System Applications
Thank you for your participation! The CO2 laser clinjce provides a concentrated infrared heating beam. Through this technique can be produced up to 80 pieces in only one step.
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. Simulatoarele ADM si principiile functionale ale ocluziei: Two en-face OCT systems have been used. The detection of these marginal adaptation problems allows all the corrections in order to avoid the failure of the prosthetic treatment.
Sectioned model without pins: Poor marginal adaptation of the metal ceramic fixed partial denture that can lead to secondary cavities to the pillar teeth.
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. Restaurarea dintilor devitali by Dorin Bratu Book 1 edition published in in Romanian and held by 2 WorldCat member libraries worldwide.
The Gypsum in excess will be removed before it becomes harder. Science of Dental Materials, ed. The model from the support.
the accu-trac system
The arms are applied on the support and are closed; the basic plate is fixed and the functioning of the system is verified. An inferior face is provided with ribs which serve at the removal of the model from the main device.
No final curing is required as in stereolithography, but since the objects are sintered they are porous. This saves some finishing time compared to stereolithography. Enter the email address you signed up with and we’ll email you a reset link. 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 working model with mobile and detachable parts can be classified as follows: However, surface finishes are not as good and this may increase the time. The ACCU-TRAC system is an efficient one fast and cheap and precise in the accomplishment of models clijice dental dies which eliminate the pines, being indicated in fixed and composed prosthetics.

A piston moves down one object layer fixee to accommodate the layer of powder. Project Page Feedback Known Problems. Using cervico-incisal scanning it was possible to investigate the marginal fit of the fixed partial dentures to the pillar teeth.
