Application Instructions
The application of OptiBond Solo Plus involves a straightforward process. Proper surface preparation, including etching, is crucial before applying the adhesive. The adhesive should then be applied, air-thinned, and light-cured for optimal bonding strength.
Surface Preparation⁚ Etching
Before applying OptiBond Solo Plus, proper surface preparation is essential to achieve optimal bonding. This process begins with etching the enamel and dentin surfaces of the tooth. The etching process involves the application of a dental etchant, typically a phosphoric acid solution, to create a micro-porous surface. This micro-porosity is crucial as it allows the adhesive to penetrate and form a strong bond with the tooth structure.
For effective etching, apply the etchant for a duration of 15 seconds to both the enamel and dentin. Following the etching period, thoroughly rinse the etched area with water to remove all traces of the etchant. It is vital to ensure that no etchant residue remains as it can interfere with the bonding process and weaken the overall bond strength. After rinsing, gently air-dry the tooth surface, ensuring it is clean and free from moisture before proceeding with the adhesive application. Proper etching is a key step in ensuring the long-term success of the restoration.
Applying OptiBond Solo Plus
Following the surface preparation, the next critical step involves the application of OptiBond Solo Plus. Using an applicator, gently apply OptiBond Solo Plus to the etched enamel and dentin surfaces. It is important to use a light, brushing motion while applying, ensuring that the adhesive is evenly distributed across the entire prepared area. The application should be done for approximately 15 seconds, allowing the adhesive to thoroughly penetrate the etched surfaces.
Avoid pooling of the adhesive in any particular area, as this can lead to uneven bonding. The goal is to achieve a thin, uniform layer of OptiBond Solo Plus on the tooth structure. This single-component adhesive is designed for easy application, eliminating the need for multiple layers which simplifies the process and reduces the risk of errors. Proper application ensures that the adhesive can effectively bond to the etched tooth surface, providing a strong foundation for the subsequent restorative material.
Air Thinning and Light Curing
After applying OptiBond Solo Plus for the recommended 15 seconds, the next step is crucial⁚ air thinning.
