末端根帽支撑的MK1附着体在下颌单侧后牙缺失修复中的临床应用

End cap support MK1 attachments in mandibular unilateral posterior teeth loss restoration and its clinical application

目的:评价末端根帽支撑的MK1附着体在下颌单侧后牙缺失修复中的临床效果。方法:以29例采用MK1附着体进行修复治疗的患者作为研究对象,实验组以10例患者修复体远中处有经根帽修复后的残根,其余19位患者作为对照组。1年后随访,从患者主观感受、临床检查及X线检查评价修复效果。结果:实验组、对照组患者对MK1附着体义齿的主观满意度分别为8.38+0.85、8.27+1.10,两组间无统计学差异(P>0.05)。实验组、对照组缺牙区牙槽嵴吸收例数分别为0例、5例,差异无统计学意义(P>0.05);实验组、对照组近缺牙区基牙牙槽骨吸收例数分别为0例、5例,差异无统计学意义(P>0.05);实验组、对照组义齿修整例数分别为1例、10例,差异有统计学意义(P<0.05)。结论:MK1附着体义齿稳定及固位性能良好,是一种较理想的下颌单侧后牙缺失的固定-活动联合修复体。末端残根根帽修复后更利于MK1的临床疗效。

Objective Evaluation end cap support MK1 attachments in mandibular clinical effect of unilateral posterior teeth loss restoration. Methods MK1 repair attachment therapy on 29 cases of patients studied,the experimental group to 10 patients in much of the restoration after root Cap restoration of residual root and the remaining 19 patients in the control group. Follow-up after one year, patients subjective experience, clinical examination and X-ray examination evaluation outcomes. Results Experimental group, control group for MK1 attachment denture patients with subjective satisfaction respectively 8.38 ±0.85, 8.27 ±1.10, no statistically significant differences between the two groups （P〉0.05）.Experiment group, and against group deficiency teeth district teeth slot Crest absorption cases number respectively for 0 cases,and 5 cases,differences no statistics meaning （P〉0.05）;experiment group, and against group near deficiency teeth district base teeth teeth slot bone absorption cases number respectively for 0 cases,and 5 cases, differences no statistics meaning （P〉0.05）;experiment group,and against group denture trimming cases number respectively for 1 cases, and 10 cases,differences has statistics meaning （P〈0.05）. Conclusion MK1 good attachment denture retention and stability, a more ideally unilateral mandibular teeth fixed-joint prostheses.After root end and root Cap repair more conducive to clinical efficacy of MK1.
