摘要: 目的: 研究locator种植覆盖义齿在老年人无牙颌修复中的的临床应用效果。方法: 纳入 2014年2月至2017年3月于滨州医学院附属医院口腔修复科接受 locator种植覆盖义齿修复的无牙颌患者,复诊时记录探诊深度(probing depth,PD)、改良菌斑指数(modified plaque index,mPLI)、改良龈沟出血指数(modified Bleeding Index,mBI)、边缘性骨吸收(marginal bone loss,MBL)。结果: 共纳入46名患者(139枚种植体),平均随访了25个月,139枚种植体均获得了良好的软硬组织效果,种植体留存率100%。平均PD、mPLI、mBI分别为2.0±; 1.2、1.5±; 0.7、0.8±; 0.5,种植体边缘骨吸收(MBL)近远中分别为(0.8±; 0.4)mm、(0.9±; 0.5)mm。口腔卫生维护不良(每次刷牙时间不足3分钟和每天次数不足2次)时PD、mPLI、mBI得分均明显高于口腔卫生维护良好时得分(P<; 0.05)。单颌种植体植入3-4枚边缘骨吸收明显小于单颌植入1-2枚(P<; 0.05)。结论: Locator种植覆盖义齿短期内能获得不错的软硬组织临床效果,设计时应尽可能增加种植体数目,永久修复后口腔卫生的正确维护是保证长期软硬组织稳定性的关键。

Abstract: Objective: To study clinical application of locator implant overdenture in elderly edentulous restoration. Methods: The edentulous patients who underwent locator implant overdenture restoration in the Department of Prosthodontics, Binzhou Medical College Hospital from February 2014 to March 2017 were included. The probing depth(PD) and modified plaque index were recorded at the time of follow-up. Plaque index, mPLI), modified Bleeding Index(mBI), marginal bone resorption(MBL). Results: A total of 46 patients(139 implants) were enrolled. The average follow-up was 25 months. The mean PD, mPLI, and mBI were 1.6±1.1, 0.9±0.6, and 0.8±0.5, respectively. The bone resorption at the implant margin was(1.2±1.0)mm, (1.1±0.9)mm. The scores of PD, mPLI, and mBI were significantly higher when oral hygiene was poor(less than 3 minutes for each brushing time and less than 2 times a day)(P<0.05). The bone resorption of 3-4 marginal implants was significantly less than that of 1-2 implants(P<0.05). Conclusion: Locator implant overdenture can achieve good clinical results in soft and hard tissues in a short time. The number of implants should be increased as much as possible when designing locator overdenture implant. Proper oral hygiene maintenance after permanent repair is the key to ensuring long-term soft and hard tissue stability.
