摘要:

背景:现阶段利用磁体的吸引力来增强下颌全口义齿、活动义齿以及颌面赝复体的固位力已取得较好的临床效果。
目的:就磁性附着体在可摘局部义齿及全口覆盖义齿中的固位力的研究状况作一综述。
方法:应用计算机检索Medline数据库(1996-01/2010-01),以“magnetic episomal agent,retention,complete denture,RPD,overdenture”为检索词;应用计算机检索中国知网数据库(1996-01/2010-01)、万方数据库(1996-01/2010-01),以“磁性附着体、固位力、全口义齿、可摘局部义齿、覆盖义齿”为检索词。
结果与结论:共收集175篇关于磁性附着体关于固位力研究的文献,中文72篇,英文103篇。排除发表时间较早、重复及类似研究,纳入33篇符合标准的文献。磁性附着体能显著提高下颌全口覆盖义齿以及可摘局部义齿的固位力,因此必须了解远中牙槽骨吸收对磁性附着体覆盖义齿固位力和功能的影响,以及局部缓冲对其改善的效果。目前大量学者对磁性附着体的材料和结构予以改进,以达到增强其固位力的目的,磁性附着体的固位力及其性能的发挥均有待于深入分析。

Abstract:

BACKGROUND: Satisfactory clinical effect has been already acquired to strengthen the retention of lower mandible complete denture, removable partial denture and prosthetic appliance utilizing the attraction force of magnet.
OBJECTIVE: To summarize the researches about the retention of magnetic attachment in the removable partial denture and complete overdenture.
METHODS: A computer search was performed in Medline database (1996-01/2010-01) using key words of “magnetic episomal agent, retention, complete denture, removable partial denture and overdenture” in English, and in CNKI database and Wanfang database (1996-01/2010-01) using key words of “magnetic attachment, retention, complete denture, removable partial denture and overdenture” in Chinese.
RESULTS AND CONCLUSION: There are 175 literatures about the retention of magnetic attachment, 72 Chinese literatures and 103 English literatures. Too old, repeated and similar studies were excluded, 33 literatures are included fitting the criteria. The magnetic attachment can significantly increase the retention of the lower mandible complete overdenture and removable partial denture. It is therefore required to understand the influence of the distal alveolar bone absorption on the retention and function of the magnetic attachment overdenture, as well as the meliorative effect on partial buffering. Many scholars have modified the materials and structure of magnetic attachment, so as to enhance the retention. Further studies are needed to further determine the retention and function of the magnetic attachment.
