Primary and secondary implant stability is of high importance for survival and success of dental implants in the short and long term. Measurements of implant stability during healing provide the opportunity to monitor the course of the osseointegration process.
To compare implant stability quotient (ISQ) by resonance frequency analysis (RFA), recorded with two different devices after implant placement.
Patients with the need of single tooth extraction in posterior sites of the maxilla and the mandible were treated in a surgical center. All patients received additional augmentation with a bovine bone substitute and platelet-rich fibrin (PRF) after atraumatic tooth extraction. After a healing period of 10 weeks, 28 self-tapping titanium-implants were placed. Implant stability was recorded with two different devices (Osstell and Penguin) at the time of implant insertion (T0), 10 days later (T1), and after 7 (T2), or 17 weeks (T3).
No implant was lost, and no postoperative complication occurred during follow-up. Patient cohort comprised 9 female (32.1%) and 19 male patients (67.9%), with a mean age of 52.8 years, 64.3 years, respectively. Mean overall insertion torque was 43.6 Ncm at implant placement with no significant difference between implant location, age, or gender. No patient dropped out. During observation period, a significant increase in mean ISQ was recorded with both devices. Significant positive correlations between insertion torque and ISQ were recorded with both devices at T0, T2, and T3. No significant differences were observed in ISQ-values between both devices, and measuring directions at any point of measurement.
Within the limitations of this cohort study, both devices were suitable for RFA-measurement and revealed comparable results. Due to the cordless design, handling of the Penquin device was more comfortable. Reusability of the Penguin MultiPeg-transducers may offer an additional benefit with regard on ecological aspects.
种植体的初期和二期稳定性对于牙种植体短期和长期的存活及成功至关重要。在愈合过程中测量种植体稳定性为监测骨结合过程的进展提供了机会。
比较种植体植入后使用两种不同设备通过共振频率分析（RFA）记录的种植体稳定性商数（ISQ）。
需要拔除上颌和下颌后牙区单颗牙齿的患者在一个手术中心接受治疗。所有患者在无创拔牙后均使用牛骨替代物和富血小板纤维蛋白（PRF）进行额外的骨增量。在10周的愈合期后，植入28颗自攻型钛种植体。在种植体植入时（T0）、10天后（T1）以及7周（T2）或17周（T3）后，使用两种不同的设备（Osstell和Penguin）记录种植体稳定性。
在随访期间，没有种植体丢失，也没有发生术后并发症。患者队列包括9名女性（32.1%）和19名男性患者（67.9%），平均年龄分别为52.8岁和64.3岁。种植体植入时的平均总体植入扭矩为43.6 Ncm，种植体位置、年龄或性别之间没有显著差异。没有患者退出。在观察期内，两种设备记录的平均ISQ均有显著增加。在T0、T2和T3时，两种设备记录的植入扭矩与ISQ之间均存在显著正相关。在任何测量点，两种设备的ISQ值以及测量方向之间均未观察到显著差异。
在本队列研究的局限性内，两种设备均适用于RFA测量，且结果相当。由于Penguin设备的无线设计，操作起来更舒适。Penguin MultiPeg传感器的可重复使用性在生态方面可能具有额外的优势。
