Contoured Sectional Metal Matrix without Ledge ($25 \text{ \textmu m}$) - Latus

Contoured sectional metal matrices from the Ukrainian manufacturer Latus are an essential tool in restorative dentistry. They are specifically designed for the accurate and high-quality restoration of the contact point and anatomical contour when filling Class II cavities (posterior teeth).

Technology and Features

• Sectional Shape: Unlike circumferential or strip matrices, sectional matrices are in the form of individual petals that are placed only on the area of the tooth where the wall is missing (the proximal surface). This provides better visualization and access to the working field.

• Contoured Shape: The matrix has a convex, anatomically correct profile that mimics the natural shape of the tooth's lateral surface. This allows for the formation of the contact point in the most convex part of the tooth, ensuring optimal contact with the adjacent tooth.

• Thickness ($25 \text{ \textmu m}$): This is a very thin matrix, ideal for use with composite materials. Minimal thickness ensures:

  • Minimal gap between the matrix and the adjacent tooth, which facilitates the restoration of a tight contact point.

  • Ease of removal after material polymerization.

• Material (Metal): Metal provides the necessary rigidity and elasticity. It allows the matrix to withstand the pressure of wedges and the separating ring system, which is essential for creating a firm contact.

• "Without Ledge": This specification means the matrix has a simple, smooth shape without additional lingual or buccal ledges (wings), making it versatile for most cases.

Advantages of Use

• Accurate Contact Restoration: In combination with the separating ring and wedges, the matrix ensures the formation of a tight, anatomically correct contact point, which prevents food impaction between the teeth.

• Contour Formation: Helps reproduce the correct contour and convexity of the tooth's lateral wall, which is important for gingival health.

• Isolation: Creates a barrier that prevents restorative material from entering the interdental space.

• Versatility: Suitable for use with composites, glass ionomers, and other restorative materials.

Latus sectional metal matrices, due to their thinness and contoured shape, are an important tool for achieving high quality and longevity in Class II restorations.
