Abstract

Surface contaminants on customized implant abutments could trigger an inflammatory response in the peri-implant tissues. The aim of this randomized controlled study was to assess the radiographic bone changes around implants restored with customized, platform-switched abutments, with and without autoclave treatment, 12 months after definitive restoration. Dental implants were placed 1 mm subcrestally in 64 systemically healthy patients (mean age: 63.3 ± 10.0 years; 31 patients had a history of periodontitis) to replace single or multiple missing teeth. According to a randomization list, abutments were subjected to steam and autoclave sterilization (43 implants, test group) or steam cleaning alone (44 implants, control group). Periapical standardized radiographs were taken at implant placement, prosthetic abutment connection, and 12 months after definitive cement-retained restoration. All implants were clinically stable without any sign of infection at the 12-month follow-up. An average marginal bone loss of 0.25 ± 0.19 mm was found in the test group compared to 0.35 ± 0.23 mm in the control group (no statistically significant difference), while the percentage of bleeding sites was significantly higher in the control group (8.7% ± 13.1% vs 19.1% ± 19.8%; P = .035). Autoclave treatment of customized abutments seems to reduce the inflammatory response around subcrestally placed implants.

使用和不使用无菌修复基台的冠下平台开关种植体的一年效果:随机对照试验
定制种植基台上的表面污染物可能会引发种植体周围组织的炎症反应。这项随机对照研究的目的是评估使用定制的平台开关基台修复的种植体在经过和未经高压灭菌处理的情况下,在最终修复 12 个月后周围骨质的放射学变化。64 名全身健康的患者(平均年龄:63.3 ± 10.0 岁;31 名患者有牙周炎病史)在牙冠下 1 毫米处植入种植体,以替代单颗或多颗缺失牙。根据随机列表,对基台进行蒸汽和高压灭菌(43 个种植体,试验组)或单独蒸汽清洗(44 个种植体,对照组)。在种植体植入、修复基台连接和骨水泥固位修复12个月后分别拍摄根尖周标准X光片。在 12 个月的随访中,所有种植体均临床稳定,无任何感染迹象。测试组的平均边缘骨量损失为 0.25 ± 0.19 mm,而对照组为 0.35 ± 0.23 mm(差异无统计学意义),而对照组出血部位的比例明显更高(8.7% ± 13.1% vs 19.1% ± 19.8%;P =;.035)。对定制基台进行高压蒸汽灭菌处理似乎可以减少胸骨下植入种植体周围的炎症反应。
