Wenn you are used to work with retainers (tensors), for Class II premolar and molar restorations, it is best to use AnGer shaped polyester matrices. These matrices provide appropriate firm hold on tooth without causing unnecessary deformations.
AnGer Polyester Tapes are made of 0.05 mm or 0.075 mm thick polyester foil. This makes it easier to fit them into interdental spaces. Offered in 3 sizes 6, 8 and 10 mm wide. Choose the most comfortable size depending on the work done!
