Bone prostheses made of glass ionomer cement are superior to those made of ceramics, especially because they are simple to produce and can be shaped easily using conventional grinding and milling tools. The prosthesis part required in each case can be shaped by the surgeon during the operation from freshly mixed glass ionomer cement, or an industrially prefabricated shaped element, which approximates to the ideal shape of the bone part to be replaced, can be adapted to the given anatomical conditions. |
