摘要

目的:本研究回顾性研究了以冠状微螺纹为特征的骨水平型2片内连接种植体系统的长期临床和影像学结果。方法:从延世大学口腔医院经验丰富的牙周病专家为691例患者放置的1845颗种植体中,选取284例患者放置的872颗种植体。这些选择的植入物随访超过10年,并纳入本研究。根据边缘骨水平的变化,使用电子记录和连续拍摄的x线片对种植体存活和治疗成功进行统计评估。结果:在12.3±2.0年的随访期间,872个种植体中有830个保持完整,种植体水平的累积存活率为95.2%,患者水平的累积存活率为88.4%。累积治疗成功率为种植体的87.0%和患者的76.1%,其特征是边缘骨丢失小于2mm。在830个存活的种植体中,113个固定体被分类为疾病,平均边缘骨损失为4.09±1.44 mm。Cox回归分析显示,长度为8 mm或更短的种植体更容易失败或发生病理性边缘骨吸收,风险比分别为3.71和2.00 (p)结论:在超过10年的随访期间,所研究的微螺纹、骨水平、2片、内连接种植体的生存和治疗成功是可以接受的。然而,较短的牙种植体表现出更高的失败倾向和过度的边缘骨质流失。

Long-term clinical and radiographic outcomes of a bone-level, 2-piece, internal connection implant system with coronal microthreads over 10 years of follow-up: a retrospective clinical study.

Purpose: This study retrospectively investigated the long-term clinical and radiographic outcomes of a bone-level type, 2-piece, internal connection dental implant system characterized by coronal microthreads.

Methods: A total of 872 implants placed in 284 patients were selected from 1,845 implants placed in 691 patients by experienced periodontists at Yonsei University Dental Hospital. These selected implants had been followed up for over 10 years and were included in the present study. A statistical evaluation of implant survival and treatment success, based on changes in marginal bone levels, was conducted using electronic records and consecutively taken radiographs.

Results: Over a follow-up period of 12.3±2.0 years, 830 of the 872 implants remained intact, yielding a cumulative survival rate of 95.2% at the implant level and 88.4% at the patient level. The cumulative treatment success rates, characterized by marginal bone loss of less than 2 mm, stood at 87.0% for implants and 76.1% for patients. Among the 830 surviving implants, 113 fixtures were classified as ailing, with an average marginal bone loss of 4.09±1.44 mm. Cox regression analysis revealed that implants 8 mm in length or shorter were significantly more likely to fail or experience pathologic marginal bone resorption, with hazard ratios of 3.71 and 2.00, respectively (P<0.05).

Conclusions: The survival and treatment success of the investigated microthreaded, bone-level, 2-piece, internal connection implants were acceptable over a follow-up period exceeding 10 years. However, shorter dental implants exhibited a higher propensity for failure and excessive marginal bone loss.
