Abstract

Methods for threading ceramic materials, such as ceramic materials used for spinal implants or other biomedical implants. In some implementations, an expected rate of shrinkage of the block upon undergoing a firing process may be determined. A scaling factor may then be applied using the expected rate of shrinkage to select a tap having a size larger than a desired thread size. A green block may then be tapped with the selected tap to form a threaded opening in the green block. The block may be machined in order to remove cracks caused by the tapping process and/or to form the block into a desired shape/size. The green block may then be fired, which may result in a reduction of a size of the block and a size of the threaded opening.
