Molar and premolar restorations are particularly complicated as they require attentive management of high biting forces and large chewing surfaces which can lead to a higher fracture risk. Hence, the materials and the tools chosen for these restorations are important in ensuring their success. Ultimately, the function of the real tooth is what you seek to emulate.
As such, the Metal Contoured Matrices for molars and pre-molars are the exact instruments you would want added to your collection. These matrices are anatomically contoured and are made of stainless steel which provides perfect approximal form and contact. Consequently, you are left with a dependable and practical restoration.
All of the Tor VM matrices come in packs of 12 pcs each and are available in two different thicknesses; 0.035 mm and 0.050 mm, so it is important to specify the thickness when purchasing the product. Additionally, the Metal Contoured Matrices designed for premolar restorations are available in the following shapes:
1) Without Ledge – No. 1.501 (matrix width is 5mm)
- Provides a smooth contoured profile and supports natural proximal contours.
2) Bilateral
- Bilateral contour design which is suitable for a variety of premolar cases and securely support consistent proximal adaptations.
- Available in two different shapes: No. 1.502 and No. 1.506
3) Left Ledge – No. 1.503
- left-sided ledge design which supports proximal adaptation.
4) Right Ledge – No. 1.504
- Right-sided ledge design which helps accommodate restorative needs.
5) One Central Ledge – No. 1.505
- A central ledge configuration with an elongated anatomical profile.
When it comes to the Metal Contoured Matrices designed for molar restorations, the available shapes are as follows:
1) Without Ledge
- Supports the natural proximal contours.
- Is available in two different matrix widths: No. 1.511 (7mm) and No. 1.517 (6mm).
2) Bilateral – No. 1.512
- Designed with a bilateral contour which is perfect for molar restorations.
3) Left Ledge – No. 1.513
- Left-sided ledge design.
4) Right Ledge – No. 1.514
- Right-sided ledge design.
5) One Central Ledge – No. 1.515
- Elongated central ledge design which supports natural proximal contours.
The above listed matrices can all be installed with a Tofflemire or Nustrem retainer, a Supermat system (which sometimes requires shortening of the matrix edges for a better fit), a Slot ring or a Slot springclip.
In closing, not only do these matrices provide precise adaptations which further help achieve accurate proximate contours but they are also notably versatile – with each shape being suited for various clinical situations. They are available individually and in two kits for Molar and Premolar which includes 6 pcs of each shape. This way you can experience the benefits of all and discover your favorites.
