Final Color

The final color of all-ceramic restorations may be influenced by the varying thickness of the dental abutment. Eighty A2 color (MO and LT) ceramic discs and eighty A3.5 color and four different thicknesses composite discs of were produced. The measurements were performed using the Vita Easyshade spectrophotometer. The results were statistically analyzed. Conclusion: There are no significant differences (perceived by the human eye) of the color parameters in the CIE L*a*b* system when comparing different combinations.

ABSTRACT Loss of tooth structure occurs due to caries, endodontic treatment, or fracture caused by trauma; restoring these teeth is difficult task for a clinician. Post and core is an option for teeth when excessive tooth structure is lost and teeth need to be restored with crown and bridge procedure. They can be prefabricated post with composite built up or a one-piece custom-made post. The custom-made cast metal post and core have disadvantage due to their color that imparts grayish hue to overlying ceramic restorations. Masking the metal core can enhance the esthetic of all ceramic restorations that are placed over the cast post and core. A case report is being presented where the metallic core was masked with ceramic built up on labial surface of metal core. How to cite this article Shah NP, Gaikwad AM, Ram SM, Nadgere JB.

Background: To present the benefits of high power lasers (Er: YAG and Nd: YAG) over the use of the high speed turbine for the extraction of ceramics restorations, without damaging the surfaces of the teeth; being a relatively easier and faster procedure without the use of anesthetic agents, and the preparation of the ceramic restorations and cementing in the single session; with a follow-up of 1 year. Objective: The benefits of lasers over high-speed turbine mechanical instrumentation for crown removal encompass efficient restoration recovery without damage to tooth surfaces; and a relatively easier and faster procedure without the use of anesthetic agents. Methods: The Er: YAG laser (no contact; 3.2-4.0 W, 20 Hz) was used to extract the porcelain prosthesis, followed by a gingivectomy with the Nd: YAG laser on tooth 12 to improve the gingival contour. The dental surfaces where the ceramic prosthesis will be cemented were scanned. Then, CAD / CAM technology was used to make the ceramic veneers that were cemented in the same session. Results: The efficacy the Er:YAG laser energy was observed by the decreased of the time to remove all-ceramic materials through ablation of bonding cements, reducing working time by 75% compared to a high-speed turbine. Conclusions: An Er: YAG laser can safely remove lithium disilicate crowns with the settings used in this study. Laser-assisted removal of all ceramic PDFs is a promising treatment protocol. The use of the Nd: YAG (2.0 W power, short 20Hz, 320 µm optical fiber, in contact) laser allowed gingivoplasty to be performed, automatically cauterizing avoiding post-operative bleeding, and facilitating the preparation of ceramic restorations the same day. The use of high-power lasers and the use of accompanying CAD / CAM technology allowed this clinical case to be completed in a single visit without the use of temporary restorations, achieving absolute patient satisfaction.   Keywords Er:YAG; Nd:YAG; Lithium disilicate ceramic; CAD/CAM.
