Periotest (Medizintechnik Gulden, Modautal, Germany) is a widely accepted implant stability measurement method, although the reliability is not well known. The aim of this in vitro study was to investigate the reliability of the Periotest in implant stability measurements. Thirty implants were placed in 3 cow ribs. The stability of each implant was measured by insertion torque, resonance frequency analyses, and Periotest and then compared. The Periotest values (PTVs) were measured by 4 different examiners. The measurements were repeated twice in both the buccal and mesial directions, for each implant at 2-hour intervals and the intra- and interobserver reliability of Periotest was measured. Results showed that the intraobserver reliability of the Periotest was excellent for the buccal PTVs but fair to poor for the mesial PTVs. The interobserver reliability of the Periotest was excellent for the buccal PTVs but poor for the mesial PTVs. No significance was found between the PTVs and IT values (P = .803) and PTVs and ISQ values, whereas a 47.1% significant correlation was detected between the IT values and ISQ values (P = .009). The present study indicates that only Periotest measurements from buccal result in excellent intra- and interobserver reliability for the quantification of the implant stability.
Periotest（德国莫道塔尔市古尔登医疗技术公司生产）是一种被广泛接受的种植体稳定性测量方法，尽管其可靠性尚不清楚。本体外研究的目的是调查Periotest在种植体稳定性测量中的可靠性。将30枚种植体植入3根牛肋骨中。通过植入扭矩、共振频率分析和Periotest测量每枚种植体的稳定性，然后进行比较。Periotest值（PTV）由4名不同的检查者测量。对每枚种植体在颊侧和近中方向每隔2小时重复测量两次，测量Periotest的观察者内和观察者间可靠性。结果显示，Periotest在颊侧PTV的观察者内可靠性极佳，但在近中PTV的观察者内可靠性一般至较差。Periotest在颊侧PTV的观察者间可靠性极佳，但在近中PTV的观察者间可靠性较差。PTV与植入扭矩值（P = 0.803）以及PTV与种植体稳定性商值（ISQ）之间未发现显著差异，而植入扭矩值与ISQ值之间检测到47.1%的显著相关性（P = 0.009）。本研究表明，仅颊侧的Periotest测量在量化种植体稳定性方面具有极佳的观察者内和观察者间可靠性。
