The aim of this study was to analyze the clinical outcomes after using an innovative implant system characterized by a modern platform-switched Morse taper connection and an osteo growth induction titanium surface (a particular type of SLA surface). Peri-implant bone loss (PBL) and implant success rate were examined after a 1- to 3-year follow-up.
The study was conducted as a cross-sectional analysis on all patients treated from January 2011 to December 2014 using CLC CONIC implants. Implants were divided into 3 main groups, based on the duration of the follow-up (1 year, 2 years, and 3 years), then subgrouped by diameter, length, and type of prosthetic rehabilitation to compare differences in PBL. X-rays were taken at the time of surgery, at prosthetic loading, at 1 year, and then annually thereafter. Previously-established success criteria were used to assess the implants. Frequency analyses and comparisons between the means (with 95% CI) were conducted for the statistical analysis of the data collected.
One hundred twenty patients met inclusion and exclusion criteria, and completed the follow-up, and were thus eligible for the study, with a total of 261 CLC CONIC implants. The mean follow-up was 22.45 months. No implants failed, giving an overall success rate of 100%. The average PBL at 1-year follow-up was 0.047 mm, at 2 years it was 0.128 mm, and at 3 years it was 0.236 mm.
The CLC CONIC implant system had a high success rate after 1 to 3 years of follow-up, in line with previous reports in the scientific literature. Combining platform switching with the Morse taper connection enabled stable bone levels to be achieved in the short to medium term.
本研究旨在分析一种创新种植体系统的临床效果，该系统具有现代平台转换式莫氏锥度连接和骨生长诱导钛表面（一种特殊类型的SLA表面）。在1至3年的随访后，检查种植体周围骨丢失（PBL）情况和种植成功率。
本研究对2011年1月至2014年12月期间使用CLC CONIC种植体治疗的所有患者进行横断面分析。根据随访时间（1年、2年和3年）将种植体分为3个主要组，然后按直径、长度和修复类型进行亚组划分，以比较PBL的差异。在手术时、修复加载时、1年时以及此后每年拍摄X线片。采用先前确立的成功标准评估种植体。对收集的数据进行频率分析和均值比较（95%可信区间）以进行统计分析。
120名患者符合纳入和排除标准并完成随访，因此有资格参与本研究，共植入261枚CLC CONIC种植体。平均随访时间为22.45个月。无种植体失败，总体成功率为100%。1年随访时平均PBL为0.047毫米，2年时为0.128毫米，3年时为0.236毫米。
CLC CONIC种植体系统在随访1至3年后成功率较高，与科学文献中的先前报道一致。将平台转换与莫氏锥度连接相结合可在短期至中期实现稳定的骨水平。
