目的:探讨整体铸造支架式可摘局部义齿添加人工牙的修理体会。方法:对240例佩戴整体铸造支架式可摘局部义齿的患者进行义齿添加人工牙修理,比较修理前后视觉模拟(VAS)评分、咀嚼功能及1年后人工牙的磨耗程度。结果:修复后VAS评分明显低于修复前,两者比较差异有统计学意义(P<0.05),但牙槽骨吸收距离未见明显差异(P>0.05)。经过修复后义齿的固位稳定及咀嚼情况较修复前明显好转,在随访1年后,人工牙大多有轻到中度的磨耗,磨耗后出现23例颌位垂直距离缩短及2例下颌前移及偏移。结论:设计合理的支架连接体,并且尽量作添加人工牙和卡环的修理,可以延长义齿的使用寿命。
Objective: To discuss the repair experience of adding artificial tooth as a whole cast stent removable partial denture. Methods: Two hundred and forty patients who had cast cast removable partial dentures were treated with artificial teeth. The VAS score, masticatory function and the degree of wear of artificial teeth after one year were compared. Results: The VAS scores after repair were significantly lower than those before repair (P <0.05). However, there was no significant difference in alveolar bone resorption distance (P> 0.05). After rehabilitated, the retention of denture was stable and chewing was significantly improved compared with that before repair. At 1 year after follow-up, most of the artificial teeth had slight to moderate abrasion. After wearing, the vertical distance of jaw reduction and 23 cases of mandibular advancement were shortened And offset. Conclusion: The rational design of the stent connector, and try to add artificial teeth and snap ring repair, you can extend the life of the denture.
