摘要:
Certain embodiments of the invention relate to a method of manufacturing a dental bridge. In certain embodiments of the method, a pre-sintered blank made from a green body of ceramic material is subjected to a machining operation that transforms the blank into an intermediate product with a bridge structure and a support body linked to the bridge structure by one or several retaining sections that extend from the support body to the bridge structure. In certain embodiments, a sintering operation is then performed on the intermediate product while the retaining section(s) still link(s) the support body to the bridge structure.
