Correlation Between Implant Stability Quotient and Percussion Sound Frequency

Area of Science:

• Biomaterials Science
• Dental Implantology
• Acoustics

Background:

• Assessing initial dental implant stability is crucial for successful osseointegration.
• The implant stability quotient (ISQ) is a common measure, but acoustic properties are less explored.
• Bone density significantly influences implant stability.

Purpose of the Study:

• To investigate the correlation between the primary implant stability quotient (ISQ) and implant percussion sound frequency.
• To evaluate how bone density affects this correlation.

Main Methods:

• Dental cone beam computed tomography (CBCT) classified pig ribs into three bone density categories (D1, D2, D3).
• 96 dental implants were placed across these categories.
• Primary ISQ was measured, and percussion sound was recorded and analyzed for frequency.

Main Results:

• A statistically significant positive correlation was found between primary ISQ and bone density (HU value).
• A statistically significant positive correlation was observed between primary ISQ and percussion sound frequency.
• Significant differences in ISQ and percussion frequency were noted between D1 and D2/D3 bone, but not between D2 and D3.

Conclusions:

• Primary ISQ and percussion sound frequency are positively correlated.
• Acoustic analysis shows potential as a non-invasive method to assess implant stability.
• Bone density is a key factor influencing both ISQ and acoustic properties.
