The primary stability of dental implants can be evaluated by insertion torque (IT) and resonance frequency analysis (RFA).
Assess the supposed relationship between the IT and RFA.
A systematic review was performed based on the PRISMA. The electronic search was performed in the PubMed, Web of Science, SCOPUS, Cochrane Library electronic, OVID, and Scielo databases. Manual searches were also performed. There was no restrictions regarding year of publication or language. The articles identified were assessed independently by 3 trained researchers. Clinical trials reporting the RFA values by means of implant stability quotient (ISQ) and IT were included.
The electronic and manual searches yielded 2017 studies. Twelve studies were included in the systematic review. There was no statistically significant correlation between ISQ and IT (r = .366; P = .079). The quality of the evidence was downgraded by risk of bias and indirectness; and the certainty of the evidence was low.
IT and RFA are independent and incomparable methods of measuring primary stability. Is important for clinicians to define only one method of evaluation for each implant.
牙种植体的初始稳定性可通过植入扭矩（IT）和共振频率分析（RFA）来评估。
评估 IT 和 RFA 之间的假定关系。
基于 PRISMA 进行系统评价。电子检索在 PubMed、Web of Science、SCOPUS、Cochrane Library 电子、OVID 和 Scielo 数据库中进行。还进行了手动搜索。没有关于出版年份或语言的限制。由 3 名经过培训的研究人员独立评估确定的文章。纳入报告通过种植体稳定性指数（ISQ）和 IT 测量的 RFA 值的临床试验。
电子和手动搜索共产生了 2017 项研究。系统评价纳入了 12 项研究。ISQ 和 IT 之间没有统计学上显著的相关性（r =.366；P =.079）。证据质量因偏倚风险和间接性而降低，证据确定性为低。
IT 和 RFA 是测量初始稳定性的独立且不可比的方法。对于临床医生来说，为每个种植体定义一种评估方法很重要。
