Key Features and Specifications

Targeted Anatomy (Code 1.491)
The 1.491 designation refers to a matrix shape specifically engineered for molar restorations, which present unique anatomical challenges. These matrices feature a wider buccolingual dimension to match the broad width of molars, a deeper cervical skirt to manage subgingival or deep interproximal margins, and a pronounced proximal contour to accurately recreate the large, convex contact areas characteristic of molars.

Material
The matrices are manufactured from thin yet robust medical-grade stainless steel. This material provides the strength required to withstand high condensation pressures commonly encountered in deep molar restorations without permanent deformation.

Thickness Options
Like other TOR VM matrices, these are typically available in multiple thickness options to suit different clinical conditions:

• 0.050 mm (Standard): For routine restorative cases requiring higher rigidity.

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

System Integration
These matrices are designed to function as part of the TOR VM sectional matrix system. They are used in combination with TOR VM separating rings or spring clips such as N 1.003 or N 1.004, which provide the necessary tooth separation force and ensure tight adaptation of the matrix against the tooth.

Versatility and Sizing
The kit typically includes a range of Small, Medium, and Large sizes, all tailored to molar anatomy. This variety ensures accurate fitting across different molar dimensions and diverse clinical scenarios.
