临床种植覆盖义齿中Locator附着体与球帽式附着体的效果比较

Comparison of the Effect between the Locator Attachment and Ball Cap Attachment Used in Clinically Implant-supported Overdentures

目的:比较临床种植覆盖义齿中Locator附着体与球帽式附着体的效果。方法:选取2013年6月-2014年6月在笔者所在医院进行覆盖义齿修复的30例无牙颌患者作为研究对象,按照随机数字表法将其分为Locator组12例和球帽式组18例。Locator组采用Locator附着体修复,球帽式组采用球帽式附着体修复,在义齿完成后观察两组种植体口腔软组织状况,并对其进行满意度调查。结果:两组的牙龈指数、菌斑指数、牙石指数等口腔软组织相关指标比较差异均无统计学意义(P>0.05)。Locator组患者种植覆盖义齿的固位、舒适、咀嚼满意度均明显高于球帽式组,差异均有统计学意义(P<0.05)。结论:Locator附着体与球帽式附着体覆盖义齿均有较好的治疗效果,患者对Locator附着体满意度有较高的评价,可以优先考虑Locator附着体覆盖义齿修复。

Objective：To compare the effect between the Locator attachment and the ball attachment in clinically implant-supported overdentures.Method：98 edentulous patients for the cover denture in our hospital from June 2013 to June 2014 were selected,they were divided into the Locator group for 12 cases and the ball cap type group for 18 cases according to the random number table method.The Locator group was given Locator attachment,the ball cap type group was given ball attachment.After the denture completion,the conditions of implant soft tissue between the two groups were observed and the satisfaction survey to the patients was made.Result：The indexes related to oral soft tissue such as the gingival index, plaque index and calculus index of the two groups,there were no significant differences（P〉0.05）.The retention,comfort and mastication satisfaction of implant-supported overdentures in the Locator group were significantly higher than those in the ball cap type group,the differences were statistically significant（P〈0.05）.Conclusion：The treatment effects of the Locator attachment and the ball attachment in clinically implant-supported overdentures are better,patients had a higher evaluation for the Locator attached body satisfaction,can give priority to the Locator attachment overdenture.
