摘要

研究目的本研究的目的是评估直接与种植体连接或使用中间基台的螺钉固位修复体修复种植体三年后边缘骨水平的变化:36名部分缺牙患者接受了72颗种植体。每位患者接受 2 个种植体和 2-4 个螺丝固位的种植修复体。试验组的种植体采用直接与种植体肩部连接的螺丝固位修复体,对照组的修复体则采用3毫米的标准化中间基台连接。在基线期、6 个月、12 个月和 36 个月的随访中记录了临床和放射学数据:36 个月时,对照组的平均边缘骨量损失为 0.13 ± 0.18 mm,测试组为 0.20 ± 0.24 mm,组间差异不显著(P > .05)。36 个月时的临床变量(探诊窝深度、探诊出血和牙菌斑指数)在各组间也无显著差异。对照组的轻微并发症发生率为 6.7%,试验组为 5.3%。两组均未出现市长并发症。患者报告结果(PROs)显示,对照组的总体满意度平均值为9.40(标清0.82),测试组为9.37(标清1.06),组间无明显差异:使用带或不带中间基台的螺钉固位局部修复体修复骨水平种植体,3年后显示出相似的影像学和临床效果。

Marginal changes at bone-level implants supporting dental prostheses with or without intermediate standardised abutments after 36 months: Randomised controlled clinical trial

Marginal changes at bone-level implants supporting dental prostheses with or without intermediate standardised abutments after 36 months: Randomised controlled clinical trial

Objective

The objective of this study is to evaluate the changes at marginal bone level at implants restored with screw-retained prosthesis connected directly to the implants or with an intermediate abutment, after 3-year follow-up.

Material and Methods

Thirty-six partially edentulous patients received 72 implants. Each patient received 2 implants and a 2–4-unit screw-retained implant-prosthesis. The test group implants received a screw-retained prosthesis connected directly to the implant shoulder, the control group prosthesis were connected through a 3-mm standardised intermediate abutment. Clinical and radiological data were recorded at baseline and at 6-, 12-, and 36-month follow-up.

Results

At 36 months, the mean marginal bone loss was 0.13 ± 0.18 mm for the control group and 0.20 ± 0.24 for the test group, with no significant differences between groups (p > .05). Clinical variables (Probing Pocket Depth, Bleeding on Probing and Plaque Index) at 36 months also showed no significant difference between groups. Minor complications frequency was 6.7% in the control group and 5.3% in test group. None of the groups suffered from mayor complications. Patient Reported Outcomes (PROs) showed a General Satisfaction mean score in the control group of 9.40 (SD 0.82) and 9.37 (SD 1.06) in the test group with no significant differences between groups.

Conclusions

Bone-level implants restored with screw-retained partial prostheses with or without intermediate abutments showed similar radiographic and clinical outcomes after 3 years.

期刊介绍: Clinical Oral Implants Research conveys scientific progress in the field of implant dentistry and its related areas to clinicians, teachers and researchers concerned with the application of this information for the benefit of patients in need of oral implants. The journal addresses itself to clinicians, general practitioners, periodontists, oral and maxillofacial surgeons and prosthodontists, as well as to teachers, academicians and scholars involved in the education of professionals and in the scientific promotion of the field of implant dentistry.
