Key Features and Function

Sectional Matrix System Component
This ring is specifically designed for use with sectional contoured metal matrices and interproximal wedges. It plays a critical role in restoring proximal tooth walls with high precision and anatomical accuracy.

Delta (Double Tine) Design

Double Tines (Delta Shape)
The defining feature of this ring is its Delta-shaped double tine (prong) design. This design offers superior wedging efficiency and enhanced stabilization during restorative procedures.

Secure Installation
The double tines allow for stable, non-fluctuating placement on the tooth, ensuring consistent positioning throughout the procedure.

Wedge Integration
The tines are specifically shaped to function optimally with both standard fixing wedges and silicone add-on wedges (such as TOR VM models 1.861 or 1.866). These tines are often inserted into preformed holes in the add-on wedges, ensuring a complete and reliable gingival seal.

Tooth Separation and Contouring

Tooth Separation Force
The inherent spring tension of the stainless steel material provides a consistent and controlled separation force between adjacent teeth. This compensates for the thickness of the matrix band and ensures a tight, anatomically correct contact point after removal.

Superior Contouring
By delivering firm separation and stable pressure, the Delta Ring allows the sectional matrix band to accurately adapt to the natural tooth contours, resulting in precise proximal anatomy.

Material and Sterilization

Material Construction
The ring is manufactured from high-tensile-strength stainless steel, ensuring durability, resilience, and resistance to repeated mechanical stress.

Sterilization
As a reusable instrument, the Delta Ring is fully autoclavable, allowing compliance with strict infection control and sterilization standards.
