对于牙列中缺失牙较多且余留牙多为残根、残冠者,或基牙临床冠较长、冠根比严重失调者,常规修复后常规义齿固位不良或摘戴、咀嚼时对基牙的侧向扭力较人造成基牙的松动、脱落、折断等问题。采用磁性附着体修复,对基牙的侧向力小,并能提供良好的固位和支持,咀嚼效率明显提高,牙槽骨吸收减少。美观性得到改善,且制作简单,经过1~4年的跟踪随访观察,获得了满意的修复效果,因其设计和制作有别于传统的可摘局部义齿,如何发挥出磁性附着体的优势并减少可能出现的问题,作出总结。
In dentition, there are many missing teeth and most of residual teeth are residual roots, residual crown, or the clinical crown of coronaries is longer, and the ratio of coronoid root is more serious than that of normal ones. Lateral torsion caused more than the abutment loose, fall off, broken and other issues. The use of magnetic attachment repair, lateral force on the abutment is small, and can provide good retention and support, chewing efficiency was significantly improved, reduced alveolar bone absorption. The aesthetics is improved and the manufacture is simple. After 1 to 4 years of follow-up and follow-up observation, a satisfactory repairing effect is obtained, and how to exert the advantages of the magnetic attachment due to its design and manufacture different from the traditional removable partial dentures Reduce possible problems and make a summary.
