Ionomeric cement--a bone glue for device fixation.

Ionocap, an ionomeric cement, is a new bone replacement material. Its generic name is polymaleinate ionomer, and it is an inert standardized biomaterial which is offered in a two component system. Since 1988 the ionomeric cement has been evaluated clinically in different situations. Its unique properties of biocompatibility, biostability and permanent adherence to bone make this new material very useful in head and neck surgery.
