Key Features and Components

Matrix Type
These are Lug Matrices (also known as universal contoured matrices with lugs). The lugs are small projecting tabs on the matrix body that allow easier handling with forceps and provide a secure purchase point for specialized tensioning or retaining systems.

Anatomical Contouring
Like other TOR VM premium matrices, these are pre-contoured anatomically to accurately restore the natural convex proximal surfaces and ideal marginal ridge heights of premolars and molars. This makes them especially suitable for Class II restorations.

Kit Contents
The kit contains 18 assorted Lug Matrices, providing the clinician with a practical range of sizes to achieve an optimal fit across different tooth dimensions.

Material and Thickness
The matrices are constructed from thin, durable medical-grade stainless steel, commonly available in 0.050 mm (standard) and 0.035 mm (ultra-thin) thicknesses. This allows for tight contact formation while maintaining excellent resistance to deformation.

Retention and Application
Lug matrices are typically used with specific retainers, tensioning rings, or wedges to press the matrix firmly against the tooth margin and generate the necessary interproximal tooth separation. The integrated lugs enable secure gripping and stable positioning during placement.

Clinical Benefits

Enhanced Manipulation
The presence of lugs provides superior control during placement, especially in areas with difficult access or limited visibility.

Accurate Contact Formation
These matrices are designed to help establish a tight, anatomically correct proximal contact, reducing common post-operative complications such as food impaction.

Versatility
Lug matrices offer an alternative approach to traditional sectional and circumferential band systems, giving clinicians greater flexibility when managing complex restorative cases.
