During certain class II restorations, particularly when separating the approximate surfaces of adjacent teeth, sectional matrices might not be the most ideal tool. At times, more complete tooth engagement is required with a more pronounced anatomical shape. In such cases, the lug matrices would be a better fit and provide the required features for a more precise and accurate restoration. This is due to the adjustable contact point which exists in these matrices, as it allows for their tightening to the adjacent tooth in any of the three directions.
The component that makes lug matrices so advanced are the holes located on the three distinct matrix edges. They are specifically designed for increased reliability in matrix handling upon installation and extraction. This is especially convenient as the installation process can be done with both the rings and the Tor VM Linear Pliers - which are equally suitable for sectional matrices. Such dual usage entails monetary benefits in addition to spatial advantages.
These anatomically preformed matrices are made of stainless steel and are available in packages of 12, 4,5 or 6 pcs. each. There are two available thicknesses: 0,050 mm and 0,035 mm and three different sizes: small, medium and large. There is also variation in models which you can choose from – either flanged or non-flanged matrices. Additionally, the Lug Titanium matrices are characterized by higher wear resistance and a more lasting quality. They also provide convenient working conditions and easier use due to their anti-glare effect
As previously demonstrated, the Lug matrices usefulness lies in its ability to adapt matrices to an adjacent tooth. However, their versatility and special features are what make them stand out in comparison to standard sectional matrices. Therefore, you must try at least one of the above-mentioned categories of Lug matrices and test out their ample advantages for yourself.
