The invention discloses a finish machining method for implant fixed bridge interfaces. The finish machining method comprises the following steps: acquiring oral cavity scanning data of a patient; designing a three-dimensional model of an implant fixed bridge according to the oral cavity scanning data; establishing a processing coordinate system by taking any interface as a reference interface and taking the reference interface as an original point; writing a body cutting processing program of the three-dimensional model of the implant fixed bridge based on the processing coordinate system, and writing an interface cutting processing program of each interface; clamping a metal disc material in cutting processing equipment, and calling the body cutting processing program by the cutting processing equipment, so as to form an implant fixed bridge body; and calling all interface cutting processing programs by the cutting processing equipment to form a plurality of implant fixed bridge interfaces. According to the finish machining method for the implant fixed bridge interfaces, the precision of positions among all the implant fixed bridge interfaces on the implant fixed bridge body can be improved, and therefore, the assembling precision of the implant fixed bridge interfaces and retainer matching interfaces is improved. The invention can be applied to the field of manufacturing of dental prostheses.
Description
technical field [0001] The invention relates to the field of manufacturing dental prostheses, in particular to a method for finishing the interface of implanted fixed bridges. Background technique [0002] The principle of implant-fixed bridge restoration is to implant the implant into the alveolar bone of the edentulous area, act as an artificial root and play a supporting role, and then place an abutment on the upper end of the implant to provide the retention part of the upper implant-fixed bridge. After the interface of the implant-fixed bridge is sequentially fixed together with the interface of the abutment retainer, the implant-fixed bridge and the artificial tooth form a whole, and finally the crown of the denture is cemented on the fixed bridge by cement. [0003] Currently, implant-fixed bridges are manufactured by subtractive machining. Firstly, the patient’s oral plaster model was manufactured using the existing technology, and the plaster model was scanned by a...
