Dental Sectional Contoured Metal Matrices & Anterior Strips Kit (TOR VM Type No. 1.398 / 1.888 / 1.330)

Precision Dental Sectional Contoured Metal Matrix Systems

Achieving tight, anatomically correct proximal contacts and preventing composite overhangs are critical challenges in direct restorative dentistry. Our Dental Sectional Contoured Metal Matrices System provides restorative clinicians with predictable anatomical contours, tight physiological contact points, and tight cervical adaptation without gingival margin impingement. Manufactured from premium surgical-grade spring stainless steel, these pre-formed matrices resist deformation under packing pressures while conforming smoothly to natural tooth morphology.

Three Specialized Clinical Configurations

• No. 1.398 – Sectional Contoured Matrices Kit (100 Pcs + 2 Rings):
  The universal benchmark for Class II posterior restorations. Includes 4 anatomical sizes (Small, Small with ledge, Medium, Medium with ledge, Large, Large with ledge) along with 1 standard round ring and 1 delta ring for optimal wedge placement[cite: 43].
• No. 1.888 – Anterior Matrices & Proximal Strips Set (30 Pcs):
  Engineered specifically for Class III, IV, and anterior diastema closures. Contains 18 proximal anterior contoured strips and 12 twin anterior matrices, restoring natural incisal and cervical contours effortlessly[cite: 43].
• No. 1.330 – Sectional Matrices with Clamping Clips (36 Pcs + 1 Spring Clamp):
  Features 9 anatomical profiles (NO.1 to NO.9) with built-in lateral subgingival extensions and a high-tension center separation clamp for seamless single-hand placement.

Key Clinical Advantages & Features

• Pre-Contoured 3D Curvature: Replicates natural proximal convexities, eliminating flat interdental surfaces and food impaction post-restoration[cite: 43].
• Dual Thickness Availability:
  • 0.035 mm (Ultra-Thin): Ideal for tight interproximal spaces and standard composites, requiring minimal tooth separation[cite: 43].
  • 0.050 mm (Standard Hard): Delivers higher rigidity for deep subgingival margins and firm condensing forces[cite: 43].
• Cervical Subgingival Ledge Extensions: Specially shaped apron tabs seal deep subgingival cavity floors, eliminating resin flash and subgingival overhangs[cite: 43].
• Resilient Separation Rings: Specially tempered alloy rings generate steady separation force between teeth, compensating for matrix band thickness to ensure rock-solid contact points[cite: 43].
• Organized Compartment Trays: Packaged in indexed multi-compartment autoclavable organizer boxes for quick chairside identification and hygienic storage[cite: 43].
