Claim:
1. A process for preparing a prosthetic element comprising a glass-ceramic body, said process comprising a) providing a basic body comprising an amorphous glass phase and containing the components of the glass-ceramic body to be prepared, and b) transferring energy to the basic body to induce conversion of a starting material of the basic body into at least one crystalline phase in a confined region, wherein energy is transferred to the confined region of the basic body by laser irradiating said region with a laser beam having a wavelength of at least 500 nm; and a first region of the basic body is subjected to a first conversion step to induce formation of a crystalline phase A in the first region, and a second region of the basic body different from the first region is subjected to a second conversion step to induce formation of a crystalline phase B in the second region, wherein the crystalline phase A formed in the first region is different from the crystalline phase B formed in the second region.
