下半口无牙颌固定修复的整体式修复设计

The design of complete prostheses for fixed dentures in edentulous mandible

随着我国经济的发展和口腔种植技术的进步,越来越多的无牙颌患者选择种植义齿来恢复咀嚼功能,提高生活质量。无牙颌种植固定修复因其美观、舒适、能够更好地恢复咀嚼及发音功能而受到患者的青睐,按照其上部结构设计可分为整体式和分段式修复。整体式设计修复效果好,预后佳,具有较多优点:如种植体植入数目少,植入位置灵活,应力分布合理,具有最佳的生物力学环境等。因此,本文就下颌牙列缺失种植固定整体式修复的研究进展作一综述。

With the development of our country's economy and the progress of dental implant technology,more and more edentulous patients choose denture implant to restore masticatory function and improve the quality of life.Implant-supported fixed prostheses of edentulous jaw is favored by patients because of its beauty,comfort,better recovery of chewing and pronunciation function.According to its superstructure design,it can be divided into complete and sectional prostheses.Complete design has good repair effect and good prognosis,which has many advantages,such as less implant number,flexible implant location,reasonable stress distribution,and the best biomechanical environment etc.Therefore,this article reviews the research progress of implant-supported fixed complete prostheses for mandible edentulous.
