This laboratory study determined the depth reached by self-shearing pins in dentin pin channels. Pin channels were prepared with the self-limiting shoulder twist drill for each of the four systems tested. Mean channel depth reached for the various pin systems was: Stabilok (small), 2.31 mm; Stabilok (medium), 1.78 mm; Reten Pin, 1.40 mm; and TMS (Regular), 2.04 mm. A coparison was also made by calculating the mean percent of penetration in relation to the depth of prepared pin channel: Stabilok (small), 92.50%; Stabilok (medium), 63.62%; Reten Pin, 66.67%; and TMS (Regular) 81.75%.
这项实验室研究确定了自攻螺纹钉在牙本质钉道中所能达到的深度。使用自限性肩部麻花钻为所测试的四个系统中的每一个制备钉道。不同钉系统所达到的平均钉道深度为：Stabilok（小号），2.31毫米；Stabilok（中号），1.78毫米；Reten Pin，1.40毫米；以及TMS（常规型），2.04毫米。还通过计算相对于所制备钉道深度的平均穿透百分比进行了比较：Stabilok（小号），92.50%；Stabilok（中号），63.62%；Reten Pin，66.67%；以及TMS（常规型）81.75%。
