Abstract
The present study was performed to compare the reproducibility of each of the porcelain and composite laminates to the selected shade (A-2). The effects of the laminate thickness (0.5 mm and 1mm) and that of the luting resin shades on the final shade of the laminate samples were also investigated. This study was carried out on 84 laminate samples i.e 42 porcelain laminate samples (IPS Corum) and 42 composite laminate samples (Tetric Ceram). The shade of the laminate materials (porcelain / composite ) which was used in fabricationlaminate was A-2. Each laminate sample was square in shape with a side ‘gth 10 mm. Half of the laminate samples had 0.5mm. - This study was conducted for the purpose of discussing the possibility degree of consensus selected color cosmetic veneer manufactured for humans indirect way by using different tones of resin adhesives. In previous studies were discussed factors affecting the degree cosmetic crust color , including shell thickness and color of teeth under the crust and the surrounding tissue crust color in many Alrasat of Assapqh . While not discuss the impact of color grade adhesive resin on the degree of color cosmetic veneer teeth.
In this study was to examine this factor influenced the degree of color cosmetic crust , was also discussed the effect of the manufactured material for cosmetic crust thickness and the degree of their color. Been making of copper specifically in the production department using the machine lathe programmed the computer to be used in the preparation of samples chaff plastic used in this study and number four and eighty sample 42 samples made from material porcelain and 42 samples made of resin material , indirectly, where the color of each sample of Alaainat. - Results were calculated and statistically tabulated were as follows : 1. Cosmetic veneer manufacturer of porcelain material and found it more compatible with the degree of pre - selected color and statistical terms burden compared with veneer manufacturer of plastic resin material. 2. Plastic shell with a thickness of 1 mm to many compatible with the selected color tone for the crust thickness of 0.5 mm. 3. When you use the adhesive resin results were more in line with the degree of pre - selected color. 4. There was also high Ahsaúih results of the effect of a color grade adhesive resin on the degree of the chosen color of the plastic shell. * Recommendations : - Prefer to use plastic crust thickness of 1 mm to hide the darker teeth. - Prefer to use the crust made of porcelain in cases of dark - colored teeth. - Recommends further development of in the directory chromatography industry to accommodate the different materials used in the manufacture of cosmetic veneer.
