OBJECTIVES
To develop and validate a method for application of the Osstell ISQ device in the assessment of mini-implant stability.
MATERIALS AND METHODS
An adaptor was developed for attachment of Osstell's SmartPeg onto a variety of orthodontic mini-implants. For validation of the adaptor, Benefit mini-implants were inserted into bone blocks that mimicked different stability conditions. The Osstell device was used to assess mini-implant stability with the adaptor (test measurement) and conventional SmartPeg attachment (gold-standard measurement). Implant stability quotient (ISQ) values were assessed for agreement, repeatability, and reproducibility.
RESULTS
Strong positive correlations were found between ISQ values obtained using the novel adaptor and the conventional attachment. Repeatability and reproducibility of ISQ values with the adaptor were similar to those obtained with the conventional attachment.
CONCLUSIONS
A method was developed and validated to assess the stability of orthodontic mini-implants using the Osstell system. The novel mini-implant adaptor provided repeatable and reproducible measurements of mini-implant stability, which agreed with those obtained using a conventional SmartPeg attachment. This adaptor permits noninvasive stability assessment of various designs of mini-implants, most of which are incompatible with the conventional SmartPeg attachment.
目的
开发并验证一种应用 Osstell ISQ 设备评估微型种植体稳定性的方法。
材料和方法
为将 Osstell 的 SmartPeg 连接到各种正畸微型种植体上，开发了一种适配器。为了验证适配器，将 Benefit 微型种植体插入模仿不同稳定性条件的骨块中。使用 Osstell 设备通过适配器（测试测量）和传统的 SmartPeg 连接（金标准测量）评估微型种植体稳定性。评估了植入物稳定性指数（ISQ）值的一致性、重复性和再现性。
结果
使用新型适配器获得的 ISQ 值与传统附件获得的 ISQ 值之间存在强正相关。使用适配器获得的 ISQ 值的重复性和再现性与使用传统附件获得的 ISQ 值相似。
结论
开发并验证了一种使用 Osstell 系统评估正畸微型种植体稳定性的方法。新型微型种植体适配器可提供微型种植体稳定性的可重复和可再现的测量值，与使用传统 SmartPeg 附件获得的测量值一致。该适配器允许对各种设计的微型种植体进行非侵入性稳定性评估，其中大多数与传统的 SmartPeg 附件不兼容。
