MK1附着体义齿返修13例原因及改良修复方式分析

目的：探讨MK1附着体义齿修复病例返修的原因及改良修复方式分析。方法：对MK1附着体义齿修复的13 例返修病例, 分别从力学和义齿制作工艺角度分析返修的原因。结果：返修的原因中，部分是由于MK1附着体自身设计的限制，部分因技术引进，初期经验不足，对义齿设计和制作环节中的技术关键有所忽略所致；针对返修病例做出相应改进, 随访1～1.5a后效果良好。结论：临床使用MK1附着体时，修复医师应熟练掌握MK1附着体的特征和适应证，加强医患沟通；对患者及时随访，提高MK1附着体义齿修复的成功率。

The reasons why 13 MK1 attachment were re-fabricated and some methods for improvement

PURPOSE: To investigate the reasons why 13 MK1 attachment were re-fabricated and to suggest some improvement methods. METHODS: Mechanics and denture production technology were reviewed in 13 cases with MK1 attachment denture to determine the causes of failure. RESULTS: In some cases, MK1 attachments were poorly designed, while in other cases problems were found during denture design and production process due to limited experiences at the initial stage. MK1 attachments were re-done based on the specific cause and the outcome was good after 1~1.5 years of follow-up. CONCLUSIONS: When using MK1 attachment, prosthodontists should be familiar with the characteristics and indications of MK1 attachment. Meanwhile, we should strengthen doctor-patient communication and follow up patients timely to improve the success rate of MK1 attached denture repair.
