MK1精密附着体用于后牙游离缺失修复的效果观察

目的研究MK1精密附着体在后牙游离缺失修复中的疗效。方法采用MK1精密附着体为26例后牙游离缺失的患者进行修复治疗,经过8个月～4年的临床观察,从主观感受、临床检查、X线检查观察修复效果。结果24例患者认为附着体舒适、稳固、易适应、咀嚼有力、不影响美观、无明显食物嵌塞。临床检查及X线检查基牙无叩痛,无松动,牙龈无萎缩,义齿受力区牙槽嵴黏膜无红肿、压痛,义齿稳固无摆动。基牙无根尖周病变及牙槽骨吸收现象。2例患者戴用2年后义齿可摘部分近中的塑料牙面碎裂,改做金属面增加强度后,使用至今无破损。结论MK1精密附着体是一种较理想的修复后牙游离缺失的附着体。

Clinical Observation of MK1 Precision Attachment in Restoration of Posterior Distal Extension Edentulous

ObjectiveTo analyze the effect of MK1 attachment in restoration of posterior distal extention edentulous. Methods MK1 attachment was used for 26 cases with posterior distal extension edentulous. After 8 months to 4 years clinical observation,the results were obtained and evaluated basing on the following indices including subjective feeling,clinical and X-ray examination. Results 24 patients consider the attachment denture as comfortable,stable,adaptable,mastication convenience,good appearance and no obvious food impaction. There was no pain on percussion,loose,gingival retraction,swelling of mucosa on the edentulous ridge,apical periodontitis or alvelor obsorbsion. Only two patients complained the broken of resin-made occulusal surface after two years wearing. Conclusion The MK1 precision attachment is a quite favorable choice to restore posterior distal extension edentulous.
