摘　　要：目的 评价磁性附着体义齿修复Kennedy Ⅰ类牙列缺损的临床效果.方法 选择KennedyⅠ类牙列缺损患者30例,采用Magfit EX-600磁性附着体作为基牙冠外固位体,应用导平面板、栓体栓道作为义齿的稳定装置,制作磁性附着体可摘局部义齿,通过临床、X线检查和患者的主观感受评估患者的满意度.结果 随访1～3年,25例患者对义齿的功能和美观表示满意;另出现牙龈炎1例,磁体脱落2例,患者基本满意,总体满意率达93.3％.2例义齿远中磨牙区部位骨吸收,导致义齿后牙区基托下沉,义齿部分塑料基托出现裂隙或破损,患者不满意.结论 采用磁性附着体义齿修复KennedyⅠ类牙列缺损具有良好的固位和稳定性,患者反馈咀嚼效果良好,外形美观、体积小巧,感觉舒适,并且对基牙有保护作用.Objective To evaluate the clinical effects of magnetic attachment on Kennedy Ⅰdentition defect.Methods Totally thirty cases of Kennedy Ⅰ dentition defect were enrolled.Magfit EX 600 magnetic attachments were applied as the extra-coronal retainer on abutment,meanwhile the guide plane and key-key way were applied as the stablizinge apparatus for dentures.The removable partial dentures with magnetic attachment were fabricated in casting framework way.After the clinical examination,X-ray and patients＇ subjective feeling interview,the satisfaction status to the dentures was evaluated.Results Totally thirty patients were followed up for a period ranging from 1 to 3 years.25 patients were satisfied with the dentures in both function and esthetic results.Additionally,one patient was found to have gingivitis,and 2 patients were found the attachments loosened.These 3patients were considered basically satisfied subjects.The overall satisfaction rate was 93.3%.The rest 2 patients were found alveolar bone absorption,which led to base plate of molar teeth region sinking,and partial plastic base plate of denture cracked or damaged.Therefore the 2 patients were considered as unsatisfied subjects.Conclusions The removable partial dentures with magnetic attachment not only exhibit characteristics as compact,aesthetic and comfort,but also supply reliable retention,stablization,excellent masticatory efficiency and enough protection for abutments in patients bearing Kennedy Ⅰ dentition defect.
