[摘要]种植义齿因其舒适美观、咀嚼功能恢复良好以及能够避免或减少天然牙的磨除，越来越多地应用于临床。钛基种植体与周围组织形成良好的骨性愈合即骨整合是种植义齿临床成功的关键。尽快达到良好的骨整合，对于实现种植体的早期负载甚至即刻负载和长期稳定十分重要。种植体表面生物化学修饰改性是提高骨整合的重要途径，各种活性肽/蛋白因其确切的成骨效果，近年来一直是国内外材料专家种植体表面修饰的研究热点。本文就种植体表面活性肽/蛋白修饰的研究进展作一综述。

    [Abstract]Implant denture has been widely used in the clinic due to its features of comfort and beauty. Besides, it brings a good recovery of masticatory function and a successful avoidance or reduction of the natural teeth’s preparation. The fine bone union(osseointegration)formed between the titanium matrix implant and its surrounding tissue is key to the clinical success of implant denture. It is quite important to achieve better osseointegration as early as possible so as to realize the early loading, even immediate loading and long-term stability of the implant. The modification of the implant surface is an important means to improve osseointegration. Various kinds of bioactive peptides/proteins have been the research focus in implant surface modification by the material experts owing to their certain bone growth. A review of the research progress is given in this paper concerning the bioactive peptide/protein modification of the implant surface. ......
