An indirect technique to prepare a multirooted pulpless tooth to receive a crown is presented. The crown also may be made on the newly completed core and its die. The procedure promotes the use of a commercial dental laboratory. The system, which uses divergent roots, results in a cast core having maximum retention.
介绍了一种为多根无髓牙制备以接纳牙冠的间接技术。牙冠也可在新完成的核及其代型上制作。该程序有助于使用商业牙科实验室。该系统采用发散的牙根，可形成具有最大固位力的铸造核。
