摘    要:目的 分析使用复合基台的全口固定式种植义齿组织面菌斑附着的特点,为指导患者口腔卫生的维护提供依据.方法 选取上颌全口固定式种植义齿修复患者21例,永久修复后3个月对修复体的组织面进行菌斑染色,收集图片通过Image J 2.1.4.7软件评估菌斑附着的特点.结果 永久修复体组织面菌斑附着面积百分比为(46.13±7.23)%.颊侧和腭侧菌斑附着面积百分比分别为(41.53±3.08)%和(53.76±3.07)%,腭侧菌斑附着面积百分比显著大于颊侧(t=16.750,P<0.001);游离端菌斑附着面积百分比为(71.86±2.00)%,显著高于前部(48.85±2.09)%(t=40.445,P<0.001)和中部(49.33±0.98)%(t=47.124,P<0.001).种植体间距离越小,永久修复体的组织面菌斑附着面积越大.结论 缩小腭侧组织面延伸、扩大种植体之间的距离、尽可能减小游离端面积有助于减少上颌全口固定式种植义齿组织面的菌斑附着.

Abstract:Objective To evaluate the plaque distribution on the fitting surface of fixed implant prostheses which were supported by multi-unit abutment. Methods 21 patients with maxillary full-arch implant-supported fixed prosthe-ses were collected. Plaque accumulation at the fitting surfaces were evaluated 3 months after restoration, by analyzing the digital photographs recorded by Image J 2.1.4.7. Results The average percentage of area covered with plaque was (46.13 ± 7.23)%. Plaque accumulation on the buccal and palatal area were (41.53 ± 3.08) and (53.76 ± 3.07)%respec-tively, with a significant difference (t=16.750, P<0.001). The free area (71.86 ± 2.00)%was significantly higher than the anterior area (48.85 ± 2.09)% (t = 40.445, P < 0.001), andalso the middle area (49.33 ± 0.98)% (t = 47.124 , P <0.001). The plaque percentage was higher when the distance between the implants was shorter. Conclusion To Mini-mize the palatal extension and free area of the prostheses ,and to maximize the distances between the implants ,were helpful to improve the oral hygiene control. It might be the key to keep a good outcome of the maxillary full-arch implant-supported fixed prostheses.
