Key Features and Components

Function
This kit is designed for use with a specialized retaining ring (not included in the matrix pack but essential for full system performance). The retaining ring provides the necessary separation force to press the matrix tightly against the adjacent tooth, ensuring accurate proximal wall formation.

Contour (Anatomy)
Each matrix is precisely pre-contoured to mimic the natural convexity of the proximal tooth surface. This results in superior anatomical shape, ideal marginal ridge height, and excellent embrasure formation, offering significant advantages over traditional circumferential matrices.

Material and Thickness
The matrices are manufactured from high-quality, durable stainless steel to withstand condensation forces during restorative procedures. They are available in two thickness options for clinical adaptability:

• 0.050 mm (Standard): Provides strength and rigidity for most cases.

• 0.035 mm (Ultra-thin): Ideal for tight interproximal spaces where minimal matrix thickness is required.

Quantity
The N 1.198 kit contains 30 pieces of assorted sectional matrices, offering a practical and versatile working supply.

Assortment (Sizing and Height Options)
The kit includes a balanced range of matrix sizes and designs to suit various clinical situations, including:

• Small, Medium, and Large sizes

• Premolar matrices with shorter height

• Molar matrices with taller height

• Matrices with prominent subgingival extensions for managing deep cervical margins

System Integration

This kit is designed to be used as part of a complete sectional matrix system, which also requires:

• Separating Rings, such as the TOR VM Delta Ring N 1.498 or similar designs, to provide strong and controlled separation force.

• Wedges, which seal the cervical margin and stabilize the matrix band.

Clinical Advantages

Tight Contact Points
The primary clinical benefit is the predictable formation of firm interproximal contact points, achieved through the strong and controlled separation provided by the retaining ring.

Natural Anatomy
The anatomical contour of the matrices significantly reduces the need for extensive post-operative finishing and polishing, saving valuable chairside time.

Minimized Flash
Accurate cervical adaptation ensures effective gingival sealing, which greatly reduces composite flash and material overflow, improving marginal quality.
