The purpose of this preliminary study was to evaluate the effect of concentrated growth factor (CGF) on dental implant stability in type 2 bone using the resonance frequency analysis (RFA) device Smartpeg®.
The researchers carried out a prospective cohort study on a sample group composed of 12 patients (mean age=67) who required dental implants. Implant socket preparation (with and without CGF) was the primary predictor variable. In each patient, two dental implants were inserted in the anterior mandible. For the test group, one dental implant socket was covered with CGF membrane, while the other socket was prepared conventionally for the control group. Implant stability, as measured by RFA, was the outcome variable. Measurements were taken using the Ostell device at the time of implant placement and at the 1st, 2nd and 4th weeks.
Mean implant stability quotients (ISQs) were 67.00±4.573 for the study group and 64.75±5.065 for the control group. The difference between the two groups was not statistically significant.
It was found that CGF did not provide beneficial effect on dental implant stability in the early healing period in type 2 bone.
本初步研究旨在使用共振频率分析（RFA）设备 Smartpeg®评估在 2 型骨中浓缩生长因子（CGF）对牙种植体稳定性的影响。
研究人员对一个由 12 名患者（平均年龄=67 岁）组成的样本组进行了前瞻性队列研究，这些患者需要植入牙种植体。种植体窝预备（有和没有 CGF）是主要的预测变量。在每个患者的前下颌骨中插入两个牙种植体。对于实验组，一个牙种植体窝用 CGF 膜覆盖，而另一个窝则为对照组进行常规准备。使用 Ostell 设备在植入时以及第 1、2 和 4 周测量 RFA 测量的种植体稳定性作为结果变量。
研究组的平均种植体稳定性指数（ISQ）为 67.00±4.573，对照组为 64.75±5.065。两组之间的差异没有统计学意义。
研究发现，在 2 型骨的早期愈合期，CGF 对牙种植体稳定性没有有益的影响。
