目的
比较新型超声器械Vector系统治疗种植体周围炎与碳纤维刮匙龈下清创的疗效。
材料和方法
该研究包括11名植入至少两个螺钉型种植体的患者，这些患者具有探诊出血（BOP）、探诊囊袋深度（PPD）≥ 5 mm、以及至少1.5 mm的放射学骨丢失和暴露的种植体螺纹，该研究作为单盲随机临床试验进行。在基线时，每例患者随机选择一个植入物，使用Vector系统（试验）进行治疗，而另一个植入物（对照）使用碳纤维刮匙进行粘膜下清创。3个月后，重复相同的治疗。在基线、3个月和6个月后记录所有种植体表面的菌斑、BOP和PPD。在研究开始前和6个月后拍摄的X光片上记录骨水平。
结果
与基线相比，试验和对照种植体周围的口腔卫生在3个月和6个月时得到改善。6个月时，4个Vector治疗部位和仅1个刮匙治疗部位停止出血。在试验组和对照组中，基线和6个月之间的PPD和骨水平均无任何差异。
结论
尽管Vector系统治疗后BOP部位数量的减少幅度大于碳纤维刮匙治疗后，但两种方法之间无显著差异。
AIM
To compare the effectiveness of treatment of peri-implantitis with a novel ultrasonic device, the Vector system, with that of subgingival debridement with carbon fiber curettes.
MATERIAL AND METHODS
The study, comprising 11 patients with at least two screw type implants with bleeding on probing (BOP), probing pocket depth (PPD) > or =5 mm, and at least 1.5 mm radiographic bone loss and exposed implant threads, was carried out as a single blind randomized clinical trial. At baseline one randomly chosen implant in each patient was treated by the Vector system (test) while the other implant (control) was treated by submucosal debridement with a carbon fiber curette. After 3 months, the same treatments were repeated. Plaque, BOP, and PPD were recorded on all implant surfaces at baseline, and after 3 and 6 months. Bone levels were recorded on radiographs taken prior to the start of the study, and after 6 months.
RESULTS
Oral hygiene around both test and control implants was improved at 3 and 6 months compared with baseline. At 6 months, four of the Vector-treated sites, and only one site treated with curettes, had stopped to bleed. In neither the test nor the control group, were there any differences between baseline and 6 months regarding PPD and bone levels.
CONCLUSION
Although there was a greater reduction in the number of sites with BOP following treatment with the Vector system than following instrumentation with carbon fiber curettes, there was no significant difference between the two methods.
