Abstract

Objectives

This retrospective study primarily evaluated whether early radiographic bone loss (ERBL) predicts progressive bone loss (PBL), and secondarily assessed its association with implant survival and peri-implant diseases.

Methods

Adults with dental implants who were followed for at least 5 years were included. Implants presenting ERBL, defined as apical migration of the interproximal marginal bone involving exposure of the implant rough surface before insertion of the final prosthesis, were classified as ERBL+; non-exposure group was defined as implants without evidence of ERBL (ERBL−). Regression analyses were performed to evaluate associations with PBL.

Results

A total of 261 implants, 87 ERBL+, and 174 ERBL− were included. [Correction added on 8 March 2026, after first publication: The preceding sentence has been corrected.] Mean follow-up periods were 8.8 ± 3.0 years for the ERBL+ and 11.5 ± 1.7 years for the ERBL−. ERBL+ exhibited significantly greater PBL than ERBL− (−1.6 ± 1.0 mm to −2.3 ± 1.7 mm vs. −0.4 ± 1.2 mm to −0.5 ± 1.2 mm; p < 0.001). Implant survival was lower in ERBL+ (67.8%) compared with ERBL− (98.3%; p < 0.001). Peri-implantitis was diagnosed in 63.2% of implants in the ERBL+ group versus 5.2% in ERBL− (p < 0.001), and 68.4% of patients versus 6.1% of ERBL− (p < 0.001). [Correction added on 8 March 2026, after first publication: The preceding sentence has been corrected.] ERBL was the strongest predictor of greater PBL (+1.46 mm; p < 0.0001). Male sex (+0.40 mm; p = 0.02), smoking (+0.61 mm; p = 0.004), each additional implant (+0.17 mm; p < 0.0001), single-crown restorations (+0.66 mm; p = 0.005), and bone-level implants (+0.32 mm; p = 0.005) were associated with increased PBL.

Conclusions

ERBL is a strong predictor of PBL and is associated with a higher risk of implant loss and peri-implantitis onset.

一项长期回顾性研究：装载前早期x线骨丢失对种植体相关结果的影响。

目的：本回顾性研究主要评估早期放射学骨质流失（ERBL）是否预测进行性骨质流失（PBL），其次评估其与种植体存活和种植体周围疾病的关系。方法：对种植体患者随访5年以上。出现ERBL的种植体被分类为ERBL+，定义为近端间边缘骨的根尖移动，包括植入最终假体之前暴露种植体的粗糙表面；非暴露组定义为无ERBL证据的植入物（ERBL-）。进行回归分析以评估与PBL的关系。结果：共植入物259个，ERBL+植入物87个，ERBL-植入物172个。ERBL+组平均随访时间为8.8±3.0年，ERBL-组平均随访时间为11.5±1.7年。结论：ERBL+比ERBL-表现出更大的PBL（-1.6±1.0 mm到-2.3±1.7 mm vs -0.4±1.2 mm到-0.5±1.2 mm）。结论：ERBL是PBL的一个强有力的预测因子，并且与更高的种植体丢失和种植体周围炎发病风险相关。

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.
