3M Filtek Z250 XT Refill Syringe Universal Composite Resin - A1 (Pack of 1 Syringe)

The 3M Filtek Z250 XT Refill Syringe Universal Composite Resin in shade A1 is a nanohybrid dental restorative material. It is engineered for a broad spectrum of restorative applications, encompassing direct anterior and posterior restorations, core build-ups, splinting, and indirect restorations such as inlays, onlays, and veneers. This composite resin offers a balanced combination of robust mechanical properties and esthetic outcomes.

Delivered in a syringe, the material allows for direct dispensing into the cavity preparation. It demonstrates excellent handling characteristics, facilitating easy sculpting and shaping without slumping or sticking to instruments prior to light curing. A dental adhesive is required to establish a permanent bond between the composite and the tooth structure.

Filtek Z250 XT is a visible light-activated composite. Each increment of the restorative material, up to 2.5 mm, can be light-cured efficiently within 10 to 20 seconds using a visible light curing unit with adequate intensity. The nanohybrid formulation contributes to high flexural strength, diametral tensile strength, and wear resistance, alongside improved polish retention.

Key Features : 

Nanohybrid composite suitable for direct anterior and posterior restorations, core build-ups, splinting, and indirect restorations.
Syringe delivery system ensures easy dispensing and sculptability with a non-sticky consistency.
Light-cured in 10-20 second increments for efficient application.
Classified as a Class II medical device.

Preparation: Clean teeth with pumice and water. Select the appropriate shade by evaluating the tooth's gingival, body, and incisal areas. Use a mock-up to test the shade match. Isolation: Use a rubber dam or cotton rolls with an evacuator for isolation. Direct Restorations: Cavity Preparation: Clean and round cavity; remove residual materials. Pulp Protection: Apply calcium hydroxide and a light-cure glass ionomer liner if needed. Matrix Placement: Use Mylar strips or matrix bands for anterior and posterior restorations. Adhesive System: Follow instructions for etching, priming, and adhesive application. Dispensing: For syringes: Turn the handle clockwise to dispense, then counterclockwise to stop flow and cap the syringe. Placement: Apply composite in increments, overfill slightly, and contour with composite instruments. Curing: Cure each increment with a high-intensity light (400 mW/cm²). Follow recommended exposure times based on shade. Finishing: Contour with fine diamonds or burs. Use finishing strips for proximal surfaces. Adjust Occlusion: Check and adjust occlusion with articulating paper and fine diamonds. Polishing: Polish with the Sof-Lex Finishing and Polishing System. Indirect Procedure: Dental Operatory: Shade Selection: Choose the shade before isolation. Preparation and Impressioning: Prepare tooth and take an impression. Laboratory Procedure: Casting and Trimming: Prepare and trim the cast, apply separating medium. Composite Application: Place die back into the articulated arch; add and slightly overfill with incisal composite. Light cure for 10 seconds, then remove die to avoid sticking. Finish curing. Remove excess composite, develop inclines and ridges. Carefully remove the prosthesis from the die; ensure clean separation from the cured restoration. Check restoration on the master die for fit, flash, and undercuts. Adjust and polish as needed. Dental Operatory Procedure: Roughen the interior surfaces of the indirect restoration. Clean the prosthesis in a soap solution using an ultrasonic bath and rinse thoroughly. Cement the prosthesis using a 3M ESPE resin cement system, following the manufacturer’s instructions
