Abstract：
OBJECTIVE: The aim of this retrospective study was to evaluate the outcomes of a two-piece implant system with a tube-in-tube internal connection after up to 15 years of clinical use.
METHODS: A retrospective follow-up examination of patients treated with internal tube-in-tube implants between 2003 and 2006 was conducted. The implant survival rates, peri-implant conditions (marginal bone loss, bleeding on probing, plaque index, probing depth), and technical complications were determined.
RESULTS: In total, 312 dental implants were placed in 152 patients. Of the original 152 patients enrolled, 245 implants in 112 patients were available for a follow-up evaluation after 11 to 15 years (mean observation time, 12.9 ± 1.1 years). The overall implant survival rate was 93.9%. Outcomes for MBL (1.49 ± 1.23 mm), PI (24.3 ± 22.2%), BOP (18.3 ± 28.7%), and PD (2.74 ± 1.21 mm) were observed. Selected parameters (time after implant surgery, smoking habits, bone augmentation (GBR)) showed an influence on MBL and PD.
CONCLUSIONS: The internal tube-in-tube implant system showed favorable long-term results. The correlation of MBL and PD with the patient-specific factor smoking habit is in accordance with other studies.
CONCLUSIONS: Camlog Root-Line implants with a tube-in-tube implant-abutment connection and a 1.6-mm polished neck configuration have demonstrated favorable long-term outcomes in daily clinical practice. However, it is important to note that these implants are no longer available on the market.

摘要：
目的：这项回顾性研究的目的是评估具有管中管内部连接的两件式植入系统在临床使用长达15年后的结果。
方法：对2003年至2006年期间使用管内植入物治疗的患者进行了回顾性随访检查。植入物的存活率,种植体周围条件(边缘骨丢失，探查时出血,菌斑指数,探测深度)，并确定了技术并发症。
结果：总计，在152例患者中放置312个牙种植体。在最初的152名患者中，112例患者中的245例植入物可在11至15年后进行随访评估（平均观察时间，12.9±1.1年）。植入物的总存活率为93.9%。MBL结果(1.49±1.23mm),PI(24.3±22.2%),防喷器(18.3±28.7%),观察到PD（2.74±1.21mm）。选定参数（植入手术后的时间，吸烟习惯,骨增强（GBR））对MBL和PD有影响。
结论：内部管中管植入系统显示出良好的长期效果。MBL和PD与患者特定因素吸烟习惯的相关性与其他研究一致。
结论：CamlogRoot-Line植入物具有管中管植入物-基台连接和1.6mm抛光颈部结构，在日常临床实践中显示出良好的长期结果。然而,重要的是要注意，这些植入物不再在市场上提供。
