“Lucky Lock“ abutments form a clever, secure and cost-effective option for prostheses fixation. The retention attachment is mainly characterized by its very low construction height and its absolute uncomplicated handling. The various matrices facilitate an easy and fast realization of the optimal stripping force and a restoration of strongly diverging implant abutments. As an additional retaining element for individual bar or CAD/CAM frameworks we also offer Mini “Lucky Lock” abutments, which can be easily integrated in existing constructions.
