套筒冠义齿修复牙周病伴牙列缺损的临床应用研究

Clinical investigation of telescopic denture treatment in periodontal diseases with denture defect

目的探讨套筒冠义齿修复牙周病伴牙列缺损的临床疗效。方法20例牙周病患者经牙周综合治疗病情稳定后进行套筒冠义齿修复,共制作套筒冠义齿24件,基牙共计146颗,其中松动牙81颗;比较分析牙周病伴牙列缺损患者修复前,修复后3、6、12个月基牙松动度、牙龈指数、牙周袋、牙槽骨高度、牙周膜宽度和硬骨板的丧失,并进行问卷调查。结果20例牙周病患者经修复治疗后,随着时间的推移,牙松动度减低,牙龈指数改善,牙周袋变浅,X线片显示基牙的牙周膜和骨硬板清晰完整,牙槽骨边缘高度未再见降低,骨密度明显增加,随访问答结果显示,患者的咀嚼功能显著提高,患者对义齿比较满意。结论套筒冠义齿修复牙周病伴牙列缺损具有良好的临床疗效。

Objective To study the clinical effects on patients with periodontal diseases after telescopic denture treatment. Methods 24 telescopic dentures in 20 patients who totally had 146 abutment teeth, including 81 of mobility were studied. The follow-up period varied from 3 to 12 months. The changes of periodontal pocket depth and gingival index and tooth mobility of patients with periodontal disease, the height of alveolar bone, periodontal width, the loss of lamina dura, questions by questionnaire were determined before and after prosthesis with telescopic denture. Results The observation time was 12 months. The results showed that the average depth of periodontal pocket and the tooth mobility decreased as time passed, and the gingival indexes were better. X-ray showed the lamina dura and periodontal ligament were clear, the height of alveolar bone remained stable, and the bone density increased. The kinds of foods they selected become more with telescopic dentures. Most of those patients were satisfied with their telescopic dentures. Conclusion The telescopic denture is a good method for the treatment of serious periodontal diseases with denture defect.
