Key Features and Function

Primary Function
The primary purpose of this clip is to create and maintain temporary interproximal tooth separation (wedging force). This separation compensates for the thickness of the matrix band and ensures that, once the clip is removed, a tight and natural contact point is established between the restored tooth and the adjacent tooth.

Design
The clip is constructed as a durable metal ring with two precisely shaped tines (forks). These tines are designed to engage accurately with the small cylindrical tubes or holes on the edges of TOR VM Saddle or Sectional Matrices, ensuring secure and stable positioning.

Application
The clip is applied using dedicated TOR VM forceps (N 1.099-2). The forceps expand the ring, allowing the clinician to place it over the matrix and along the proximal box margins. Once released, the inherent spring tension of the ring generates the required separating force.

Material
The clip is manufactured from robust, corrosion-resistant stainless steel or Nickel-Titanium (NiTi). These materials provide excellent spring memory, allowing the clip to withstand repeated sterilization cycles while maintaining consistent separating power.

Stability and Gingival Adaptation
The continuous tension of the ring holds the sectional matrix band tightly against the gingival margin. This secure adaptation minimizes the risk of restorative material overflow (flash or overhang) and improves marginal integrity.
