Method for embedding threaded apertured button in base of dental cast |
摘要 |
A novel method for embedding a button into a dental cast by forming a cavity and pouring a cold setting material such as a plastic into which a screw is inserted while the poured button is in the fluid form before final setting. The screw has a notch in at least one thread so that the molding material forms an interlock or detent in the notch, which is sheared upon removal of the screw.
