Ivoclar Variolink Esthetic DC (Dual-Curing) Kit & Refills is a versatile and crucial component in modern dentistry, primarily used for the adhesive cementation of dental restorations. Its dual-curing capability combines the benefits of both light-curing and self-curing mechanisms, ensuring a secure and durable bond between restorative materials and the tooth structure. This feature provides flexibility in various clinical scenarios, where complete light exposure may be challenging. The composite is meticulously engineered to facilitate precise and reliable cementation of dental restorations. It plays a pivotal role in anchoring restorations like crowns, bridges, inlays, onlays, and composite fillings securely in place. Its adhesive properties promote a strong bond, contributing to the longevity of dental work. Furthermore, the composite is formulated for ease of use, enhancing its practicality for dental professionals. Whether in the context of esthetic restorations or structural repairs, this composite stands as an invaluable tool in the armamentarium of dental professionals, promoting optimal patient outcomes and the preservation of oral health.
Indication

Direction To Use:
Initial Situation:
- Assess and identify tooth 36 with an insufficient composite filling as the target for restoration.
Preparation:
- Prepare the tooth by removing the existing insufficient composite filling and any additional decay or damaged tissue. This step is essential for creating a clean and suitable surface for the new restoration.
CAD Image of e.max CAD-Restoration:
- Create a computer-aided design (CAD) image of the e.max CAD restoration, which is a ceramic restoration made from lithium disilicate glass ceramic. This image serves as a digital blueprint for the new restoration.
Try-In of Crystallized and Characterized Restoration:
- Try in the crystallized and characterized e.max CAD restoration to ensure it fits properly and assess its appearance. Variolink Esthetic Try-In paste (neutral shade) is used for this purpose.
Etching of Prepared Dental Surface with 37% Phosphoric Acid (Total Etch):
- Condition the prepared dental surface by etching it with 37% phosphoric acid, typically known as Total Etch. This step enhances the bonding between the tooth and the new restoration.
Application of Adhese Universal using the VivaPen:
- Apply Adhese Universal, a dental adhesive, to the prepared tooth surface. This is often done using the VivaPen for precise and controlled application.
Pre-Polymerization of Excess Material:
- Pre-polymerize any excess adhesive material by using a dental curing light, such as the Bluephase Style. The quarter technique is employed, with a maximum distance of 10mm and a 2-second exposure per quarter of the restoration.
Convenient Removal of Excess Material with a Scaler:
- Remove any excess adhesive material using a scaler, ensuring the restoration's fit and appearance are precise.
Application of Glycerin Gel (Liquid Strip):
- Apply glycerin gel, also known as Liquid Strip, to protect the restoration during the final curing process.
Final Restoration After One Week:
- The final restoration is typically completed. The patient may return for a follow-up visit after one week to assess the stability and success of the restoration.
