目的:研究支架式可摘局部义齿对中重度牙周炎伴牙列缺损患者的修复效果。方法:对20例完成牙周治疗的中重度牙周炎患者采用支架式可摘局部义齿修复,分别记录义齿戴入时,戴入后3、6、12、24个月的菌斑指数(PI),龈沟出血指数(SBI)和牙周袋深度(PD)。结果:24个月后PI和SBI指数增加,但12个月后和24个月后PD指数下降情况与义齿戴入前比较均有统计学意义。结论:支架式可摘局部义齿对修复中重度牙周炎伴牙列缺损患者具有稳定基牙,促进牙周组织愈合的作用。
Objective: To study the effect of scaffold removable partial dentures on patients with moderate-severe periodontitis and dentition defect. Methods: Twenty patients with moderate-severe periodontitis who underwent periodontal treatment were treated with removable partial dentures. The plaque index (PI) at 3, 6, 12, and 24 months after wearing ), Sulcus bleeding index (SBI) and periodontal pocket depth (PD). Results: After 24 months, PI and SBI index increased. However, the decrease of PD index after 12 months and 24 months was statistically significant compared with that before denture. Conclusion: Stent-removable partial dentures have the effect of stabilizing abutments and healing of periodontal tissues in patients with moderate-severe periodontitis and dentition defects.
