ADDITIVE AND SUBTRACTIVE COMPOSITE PROCESSING AND FORMING METHOD FOR PERSONALIZED DENTAL IMPLANT ABUTMENT

摘要

An additive and subtractive composite processing and forming method for a personalized dental implant abutment, the additive and subtractive composite processing and forming method for a personalized dental implant abutment comprises the following steps: designing a personalized implant abutment: designing a personalized implant abutment according to medical case; data processing: designing cutting allowance for a part of the personalized implant abutment that needs to be cut, performing sectioning processing, which is required for additive manufacturing, on the abutment, and planning a cutting path for cutting the abutment; additive manufacturing: processing a semi-finished product of the abutment by means of additive manufacturing; subtractive manufacturing: cutting the semi-finished product of the abutment to manufacture the personalized implant abutment. The processing and forming method combines the advantages of additive manufacturing and subtractive manufacturing to achieve high efficiency and high precision for a personalized implant abutment, the method being suitable for cobalt-chromium alloys, titanium, titanium alloys and so on, and thus the range of available materials is wider.
