_Occlusal-proximal restorations in the pos- terior region are fabricated frequently using pre- formed sectional metal matrices. These matrices are curved and very thin to facilitate reconstruc- tion of the anatomical tooth shape. A matrix re- tainer is not required for these matrices. However, they are sensitive, sometimes difficult to insert and even more difficult to remove if they adhere to the composite of the restoration. The new forceps have especially been designed for inserting and removing this type of matrix. It fulfils a number of requirements, including: _curvedworkingbeakstomaintaintheanatomical shape of the matrices; _sufficiently thin beaks to enable insertion into the occlusal and proximal space; _perfectly designed to allow for effective clamp- ing; _rigid working tips with maximum grip to ensure reliable clamping, so that a matrix adhering to the composite material of the restoration can be removed quickly; _resistant and sterilisable for daily use; and _in the open position, one working tip can be pre- cisely positioned, while the other tip can easily be moved into position for gripping._ 32 I I industry news _ Kohler Medizintechnik cosmeticdentistry 3_2011 Kohler Matrix forceps with tungsten carbide coating Kohdent Roland Kohler Medizintechnik Bodenseeallee 14–16 78333 Stockach Germany info@kohler-medizintechnik.de www.kohler-medizintechnik.de cosmeticdentistry _contact Fig. 1 Fig. 2 Fig. 3 Fig. 4 Fig. 5
