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.
