Description

Clearfil Ray Posterior CAS NO 150825-41-5 is a high-performance, light-cured dental composite resin designed for posterior restorations. This advanced material is engineered to deliver exceptional durability, wear resistance, and a precise color match, making it a cornerstone of modern restorative dentistry. It is an essential component for dental professionals and laboratories seeking reliable, long-lasting solutions for direct fillings and core build-ups.

Application

• Direct Posterior Restorations: Primary use for Class I and Class II fillings in molars and premolars, where high masticatory forces are present.
• Core Build-Up Material: Used to rebuild the coronal portion of a tooth prior to the placement of a crown, providing a stable foundation.
• Foundation for Indirect Restorations: Serves as an ideal base material for inlays, onlays, and crowns fabricated in a dental laboratory.
• Repair of Existing Restorations: Effective for repairing chipped or fractured composite or amalgam fillings.
• High-Stress Bearing Areas: Suitable for use in areas subject to significant occlusal load due to its superior mechanical properties.
