How to Finish All On 4 Cases with Nano Ceramic, Trilor Bar, Pink Layering Tutorial
TLDRThis tutorial offers a comprehensive guide on the All-on-Four dental procedure using Nano Ceramic and Trilor Bar. The process begins with milling the Nano Ceramic jacket in a dedicated program, followed by preparing the Trilor Bar and ensuring a passive fit. The surfaces are meticulously cleaned and treated with a bonder before fusing the two components. The restoration is then shaped and contoured with attention to natural aesthetics. The video demonstrates the layering of pink composite to replicate gum tissue, using various shades and tools for a realistic appearance. The final steps include curing, staining to simulate veins, and applying a glaze for a lasting finish. The method is designed for immediate practical application, as evidenced by a student's successful case featured in the video.

Q & A
What is the main material used for the nano ceramic jacket in the All on Four cases?
-The nano ceramic jacket is milled from a high performance techno polymer matrix with 78% zirconia and multi-directional glass fiber reinforcement.
What type of burs are recommended for grinding the nano ceramic after milling?
-Diamond or tungsten carbide burs are recommended for grinding the nano ceramic after milling.
How is the surface prepared before fusing the Trio bar to the nano ceramic jacket?
-The surface is prepared by steam cleaning both the jacket and the bar to remove oil and dirt, followed by sandblasting with aluminum oxide at 110 mu at two bar.
What is the role of a bonder in the process of fusing the Trio bar to the nano ceramic jacket?
-The bonder, such as PEG Bond or Bond LC, acts as a mediator between the materials and the fusing agent, ensuring a strong bond between the Trio bar and the nano ceramic jacket.
What is the recommended curing time for the bonding agent in a UV box?
-The recommended curing time for the bonding agent in a UV box is no longer than 90 seconds.
How is the excess cement cleaned off after joining the parts together?
-The excess cement is cleaned off with a micro brush after joining the parts together.
What is the purpose of using a hot steam cleaner to remove wax from the excess holes in the bar?
-The hot steam cleaner is used to remove wax from the excess holes in the bar to ensure a clean surface for the cement and to prevent contamination.
How does the layering of the pink tissue with composite material contribute to the final appearance of the restoration?
-The layering of the pink tissue with composite material helps to create a natural and three-dimensional appearance, mimicking the look of the patient's gum tissue.
What is the significance of applying a trans cover gel for the final curing cycle?
-The trans cover gel is spread across the entire surface of the pink to eliminate the inhibition layer, ensuring a thorough curing of the restoration and preparing the surface for polishing or glazing.
Why is it important to avoid using light cure only resins in this process?
-Light cure only resins can be difficult to cure later in the process, which may affect the durability and integrity of the restoration.
What is the recommended method for glazing the surface of the restoration?
-Nanov vanish from Draver is recommended for glazing the surface due to its ability to be applied very thin and not yellow over time.

π Nanoceramic Jacket and Trio Bar Preparation
This paragraph outlines a comprehensive tutorial on creating a nanoceramic jacket and Trio bar. It begins with milling the nanoceramic jacket using a dedicated program and a disc containing 78% C Trois, a high-performance polymer matrix. The recommended milling strategy involves diamond or tungsten carbide burs. After milling, a fit check is performed to ensure a passive fit of the Trio bar into the jacket. The surfaces are prepared by steam cleaning and sandblasting with aluminum oxide. A bonder is applied to both materials, and they are fused together using a resin. The restoration is then cured in a light box for 7 minutes. The paragraph emphasizes the importance of cleaning the materials, preparing surfaces, and ensuring a secure fit before proceeding to the next steps.
π¨ Layering and Glazing the Pink Tissue Nano Ceramic
The second paragraph details the process of layering and glazing the pink tissue on the nano ceramic restoration. It starts with applying a dark pink composite at the junction of natural tissue and the Trio bar, followed by a light pink layer for a more natural emergence profile. The light pink is also used around the neck of the teeth, with flowable pink being easier for small areas. The paragraph explains the use of a silicone tool and modeling liquid for blending and achieving a seamless junction. It also covers the application of red and blue stains to mimic veins and the use of orange pink paste for the final layer. The restoration is then cured in a UV light box and any gaps are filled before a final curing cycle with a trans cover gel to ensure a thorough curing and eliminate the sticky layer on the surface.
π Final Polishing and Glazing
The final paragraph focuses on the finishing touches to the restoration, including polishing and glazing. It emphasizes the importance of using a glaze that does not yellow over time, such as Nanov Vanish, and applying it carefully to avoid bubbles or pits. The glaze is applied for approximately 4 to 5 minutes in the UV light box. The paragraph concludes with a call to action for viewers to like, share, and subscribe to the channel, and to watch a related video on contouring teeth for a more in-depth understanding of achieving natural-looking results.
