Abstract

Introduction. The technologic procedures to realise galavano-ceramic fxed partial dentures can lead to aeric inclusions, at various depths in the ceramic layers. These material defects could initiate partial or total fractures in the esthetic parts of the dentures with the detachment of these from the infrastructure. The aim of this study was to use a non-invasive method in order to analize galvano-ceramic fxed partial dentures. Method and the material. Twenty-three units galvano-ceramic fxed dentures have been used for this study (fg.1, 2). 250 slices at an interval of 20 microns each have been created for each investigation. The OCT system employed in this investigation was the one using the 1300 mm wavelength. Results. As a result of OCT investigation of the galvano-ceramic fxed partial prosthesis, various material imperfections of the ceramic mass, situated at the cervical areea, with different volumes and forms, have been identifed. 3D reconstructions were developed from bidimensional image slices. Conclusions. In conclusion, the optical coherent tomography is a non-invasive technique that permits the detection of structural imperfections in the galvano-ceramic fxed partial prosthesis.
