背景资料：共振频率分析（RFA）在临床上用于评估植入物稳定性，该应用的相关性已被广泛接受。然而，近十年来，共振频率（RF）与种植体稳定性的其他参数（如组织形态计量学骨-种植体接触（BIC）参数）之间的关系一直存在争议。目的：分析和澄清RF与组织形态计量学BIC参数之间存在争议的关系。（9mm长，空组4.0mm; Biohorizes（R）Implant Systems Inc.，Birmingham，AL，USA）植入6只比格犬下颌骨中。在植入物安装时以及植入物取出前第1、2、4、6和8周的监测期间，使用磁性Osstel Mentor（R）器械进行RFA评估。分别于术后8、6、4、2、1、0周处死动物，取出种植体。一组在植入后即刻的时间0获得。将样品包埋在甲基丙烯酸甲酯聚合物（Technovit（R））中并沿其长轴沿着切割。通过基于背散射扫描电子显微镜（BS-SEM）图像的非主观和系统方法评估BIC值。将不同时间点的BIC%与RFA评估的相应种植体稳定性商（ISQ）值进行比较。结果：BIC和ISQ值（Osstell Mentor（R））之间没有统计学显著相关性。这两个参数之间的关系的情况下，是在协议与以前的几项研究在人类和实验animals.Conclusions：BIC和ISQ值之间缺乏相关性表明，ISQ确定RFA是不能够识别RF和组织形态计量学数据之间的关系。
Background: Resonance frequency analysis (RFA) is applied clinically for the assessment of implant stability, and the relevance of this application is widely accepted. However, the relationship between resonance frequency (RF) and other parameters of implant stability, such as the histomorphometrical bone-to-implant contact (BIC) parameter, has become controversial in the last decade.Objective: To analyse and clarify the controversial relationship between RF and histomorphometrical BIC measurements.Material and methods: A total of 36 dental implants (9 mm length, empty set 4.0 mm; Biohorizons (R) Implant Systems Inc., Birmingham, AL, USA) with a soluble blasting media (sandblasting with soluble particles) surface were implanted in six beagle dog mandibles. RFA assessments were performed with a magnetic Osstel Mentor (R) device at the time of implant installation, and during the monitoring period at weeks 1, 2, 4, 6 and 8, before implant retrieval. The dogs were sacrificed and the implants were removed in block after 8, 6, 4, 2, 1 and 0 weeks, respectively. One group was obtained at time 0, immediately after the implantation. The samples were embedded in methyl methacrylate polymers (Technovit (R)) and cut along their long axis. BIC values were assessed by a non-subjective and systematic method based on backscattered scanning electron microscopy (BS-SEM) images. BIC% at the different time points was compared with the corresponding implant stability quotient (ISQ) values of the RFA assessment.Results: No statistically significant correlation between BIC and ISQ values (Osstell Mentor (R)) was identified. The absence of a relationship between these two parameters is in agreement with several previous studies in humans and experimental animals.Conclusions: The lack of correlation between BIC and ISQ values suggests that ISQ as determined by RFA is not able to identify the relationship between RF and histomorphometrical data.
