In a method for producing a bridge structure with or for tooth-simulating parts from a ceramic blank, an outer shape of the bridge structure is milled or formed together with sections retaining the bridge structure in the blank. The presintered bridge structure is released from the blank via the sections and is placed in a machining arrangement with a support for the respective bridge structure part and/or tooth- simulating part. The bridge structure thus released and supported is thereafter machined in the presintered state. The invention also relates to an arrangement for a bridge structure provided or intended for tooth- simulating parts and made of ceramic presintered material. By means of the invention, the machining can be done on relatively softer material, which places fewer demands on the machining and accelerates the latter. |
