摘要
这项回顾性临床研究比较了两种不同的专业维持治疗(MT)方法(有无定期移除和净化假体组件)在植入物功能5年后对植入物周围炎症临床和生化参数的影响。基于患者记录的回顾性分析用于评估同一临床医生在私人诊所放置的牙科植入物周围的炎症临床和生化参数。在基线和每个随访年测定斑块指数(PI)、植入物周围探查深度(PPD)、粘膜退缩(REC)、探查出血(BOP)和放射学边缘骨水平。此外,在最后一次随访时,还评估了种植体周围的溃疡内活性金属蛋白酶8(aMMP-8)水平。所有参与者均接受MT测试,召回间隔为6个月。共选择了92名患者和132个植入物。在研究期结束时,12名植入12个植入物的患者被归类为辍学患者。其余80名患者和120个植入物分为两组:第1组(42名患者,62个植入物)接受MT,定期移除和净化假体组件;第2组(38名患者,58个植入物)接受MT,不定期移除和净化假体组件。在PI、PPD和REC方面,两组之间没有发现统计学差异。第1组出现BOP的部位数量在统计学上显著增加(12.4%vs 6.2%)。第2组的边缘骨丢失在统计学上高于第1组(0.23±0.6 mm vs 0.78±0.3 mm)。aMMP-8在第1组中的沟内水平在统计学上高于第2组。MT期间定期移除和净化假体组件的补充应用对植入物周围组织的炎症状态有显著的积极影响。
Effects of maintenance implant therapy with and without periodic removal and decontamination of prosthetic components on inflammatory peri-implant parameters.
This retrospective clinical study compared two different professional maintenance therapy (MT) approaches (with and without periodic removal and decontamination of prosthetic components) on peri-implant inflammatory clinical and biochemical parameters after 5 years of implant function. A retrospective analysis based on patient records was used to assess inflammatory clinical and biochemical parameters around dental implants placed by the same clinician in a private practice. The Plaque Index (PI), peri-implant probing depth (PPD), mucosal recession (REC), bleeding on probing (BOP), and radiographic marginal bone level were determined at baseline and at each follow-up year. Moreover, at the last follow-up visit, the peri-implant intrasulcular levels of active metalloproteinasis 8 (aMMP-8) were also assessed. All participants were under MT with a 6-month recall interval. A total of 92 patients with 132 implants were selected. At the end of the study period, 12 patients with 12 implants were classified as dropouts. The remaining 80 patients and 120 implants were classified into two groups: Group 1 (42 patients, 62 implants) received MT with periodic removal and decontamination of prosthetic components; Group 2 (38 patients, 58 implants) received MT without periodic removal and decontamination of prosthetic components. No statistical differences were found between the groups regarding PI, PPD, and REC. Group 1 presented a statistically significant higher number of sites with BOP (12.4% vs 6.2%). Marginal bone loss was statistically higher in Group 2 than in Group 1 (0.23 ± 0.6 mm vs 0.78 ± 0.3 mm). Intrasulcular levels of aMMP-8 were statistically higher in Group 1 than in Group 2. The supplemental application of periodic removal and decontamination of prosthetic components during MT had a significantly positive effect on the inflammatory status of peri-implant tissues.

The International Journal of Periodontics & Restorative Dentistry will
publish manuscripts concerned with all aspects of clinical periodontology,
restorative dentistry, and implantology. This includes pertinent research
as well as clinical methodology (their interdependence and relationship
should be addressed where applicable); proceedings of relevant symposia
or conferences; and quality review papers. Original manuscripts are considered for publication on the condition that they have not been published
or submitted for publication elsewhere.
