Assessment of Pain Associated With Insertion Torque and Correlation of Primary Implant Stability Measurement Methods

Assessment of Pain Associated With Insertion Torque and Correlation of Primary Implant Stability Measurement Methods

The objective of this observational study is to evaluate the primary stability of dental implants and the relationship between insertion torque and patients' pain levels assessed with the visual analogue scale (VAS)

Primary implant stability plays a key role in providing osseointegration. Higher insertion torque indicates higher primary stability. However, the effect of increased insertion torque on patient pain levels has not been clearly demonstrated. Several methods for measuring primary stability have been defined so far. Insertion torque, periotest measurements, and resonance frequency analysis are mostly preferred due to their ease of use and non-invasiveness.

The aim of the present study is to evaluate the relationship between insertion torque and patients' pain levels assessed with the visual analogue scale (VAS) and to assess the relationship between insertion torque, periotest measurements, and resonance frequency analysis.
