摘　　要：婴幼儿乳牙残冠残根在去净龋蚀组织后,其抗力形与固位形均较差,常规修复及非吸收短桩修复易出现修复体脱落的现象;生物修复虽能改善修复效果,但存在伦理问题及潜在的排斥和感染风险;聚乳酸可吸收内固定装置的应用,为婴幼儿乳牙残根的修复提供了广阔前景。本文就近年乳牙残冠残根修复治疗的现状作一综述。Restorative therapy for residual crown and root resulting from early childhood caries has been very difficult to perform in clinical settings. However, few non-infected tooth structures may be retained when gross carious lesions are removed. As a result, restoration by the traditional method or short non-absorbable post method will cause teeth to fall off easily because of poor resistance and retention by the teeth. Recently, biological restoration has become a novel restorative method for treating the residual root of deciduous teeth. This technique has turned out to be an acceptable and effective treatment method. However, certain ethical issues on this treatment method arise, which can potentially lead to rejection or a risk of cross infection to the recipient. The application of polylactic acid（PLA） absorbable material as intracannel fixation in children has now resolved these problems. Studies have demonstrated that PLA is a promising material for the restorative treatment of residual root in deciduous teeth. This article presents a review of the research progress on restorative therapy for residual crown and root of deciduous teeth in recent years.
