Abstract

Introduction: This retrospective study aimed to evaluate the influence of insertion torque and various clinical parameters on directional changes in implant stability, as measured by resonance frequency analysis (RFA), over a 12-week healing period.

Materials and methods: A total of 82 implants placed in 36 patients were analyzed. Insertion torque values (<35 Ncm or ≥35 Ncm) and Implant Stability Quotient (ISQ) measurements in buccolingual (BL) and mesiodistal (MD) directions were recorded intraoperatively and at weeks 1, 4, and 12. ISQ trends were compared across clinical variables including implant diameter, shape, length, placement timing, surface type, anatomical location, and patient gender.

Results: ISQ values demonstrated a time-dependent pattern, with an increase at week 1, a dip at week 4, and a rebound by week 12. Statistically significant changes were observed in both BL and MD directions (p < 0.05). Insertion torque ≥35 Ncm was consistently associated with higher ISQ values at all time points. Implant diameter and patient gender showed limited, time-specific effects. Other parameters, including implant shape, length, placement timing, surface type, and location, did not significantly affect ISQ values. Four implants failed during follow-up, corresponding to a cumulative success rate of 95.1%.

Conclusion: Insertion torque is a significant predictor of early implant stability. While ISQ values follow a dynamic healing pattern, direction-specific RFA provides valuable insights into changes in stability. These findings support the complementary use of insertion torque and RFA in clinical implant monitoring, particularly during the early healing phase.

种植体稳定性的时间依赖性变化和临床参数的影响：一项为期12周的基于共振频率分析的研究

简介：本回顾性研究旨在评估植入扭矩和各种临床参数对种植体稳定性方向变化的影响，通过共振频率分析（RFA）测量，超过12周的愈合期。材料与方法：对36例患者共82颗种植体进行分析。插入扭矩值(结果：ISQ值表现出时间依赖性模式，第1周增加，第4周下降，第12周反弹。BL、MD方向变化均有统计学意义（p < 0.05）。插入扭矩≥35 Ncm在所有时间点均与较高的ISQ值一致相关。种植体直径和患者性别表现出有限的、时间特异性的影响。其他参数，包括种植体形状、长度、放置时间、表面类型和位置，对ISQ值没有显著影响。随访失败4例，累计成功率95.1%。结论：植入扭矩是早期种植体稳定性的重要预测指标。虽然ISQ值遵循动态愈合模式，但特定方向的RFA提供了对稳定性变化的有价值的见解。这些发现支持在临床植入物监测中补充使用插入扭矩和RFA，特别是在早期愈合阶段。
