Abstract: Cleft alveolar is the bone defect in maxillary alveolar which is always complicated by cleft lip and palate. So far， using autogenous bone to repair bone defect in cleft alveolar is primary method. But，the method of  autogenous bone graft would lead to postoperative pain at the place providing bone， legacy scars on the skin， action inconvenience， unexpected hurt of the donor site or infection after surgery and so on. These complications would make the patients undertake more risks. The most important thing is that the heavy psychological burden may be arising in patients or patients’ parents. Thus， this method is hard to be accepted by patients and their family. With the gradual widespread of the cleft alveolar bone graft restoration，the method of using artificial material to substitute autogenous bone to restore cleft alveolar is taken by more people gradually. In this article the species， principle and result of the cleft alveolar restoring materials are compared. It will be the future direction that artificial material substitutes autogenous bone to restore cleft alveolar ultimately.
