Key Features and Components

Function
This kit is designed to be used with a specialized retaining ring (not included in the matrix pack but essential to the system). The ring provides the separation force needed to press the matrix tightly against the adjacent tooth, ensuring proper containment and shaping of the restorative material.

Contour (Anatomy)
Each matrix is precisely pre-contoured to mimic the natural convex anatomy of the proximal tooth surface. This results in superior anatomical form, ideal marginal ridge height, and excellent embrasure formation when compared to traditional circumferential matrix systems.

Material and Thickness
The matrices are constructed from high-quality, durable stainless steel. For clinical flexibility, they are typically available in two thickness options:

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

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

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

Assortment (Sizing and Height Options)
The kit includes a balanced assortment to suit different clinical situations, including:

• Small, Medium, and Large sizes

• Premolar matrices with shorter height

• Molar matrices with taller height

• Matrices with extended subgingival borders for managing deep cervical margins

System Integration

This kit is intended to be used as part of a complete sectional matrix system, which also requires the following components:

• Separating Rings, such as the TOR VM Delta Ring N 1.498 or similar designs, which generate strong and consistent separation force.

• Wedges, used to seal the cervical margin and stabilize the matrix against the tooth.

Clinical Advantages

Tight Contact Points
One of the main benefits of this system is the predictable creation of firm interproximal contact points, achieved through the controlled tooth separation provided by the retaining ring.

Natural Anatomy
The contoured matrix design significantly reduces the need for excessive finishing and polishing, saving valuable chairside time while achieving natural tooth anatomy.

Minimized Flash
Accurate cervical adaptation helps seal the gingival margin effectively, greatly reducing composite flash and improving marginal integrity.
