中文摘要：

目前成功的人工种植牙材料主要是钛及钛合金，然而有无更理想的材料应用于人工种植牙，一直以来是牙种植体材料研究发展的重点。多孔钽作为具有良好生物相容性的骨植入材料，在骨科领域得到了广泛应用，受到人们的重视。近年来，多孔钽开始被用作人工种植牙材料，表现出良好的应用潜力。本文将对多孔钽人工种植牙的研究进展作一论述。

英文摘要：

At present, the successful dental implant materials are titanium and titanium alloy. However, whether a more ideal material can be used in dental implants, which has been the focus of dental implant materials research and development. With good biological compatibility, porous tantalum has been widely applied in the field of orthopedics and received people＇s attention. In recent years, porous tantalum has been used as a dental implant material, and it has a good application prospect. In this paper, we discuss the research progress of porous tantalum dental implant
