Abstract：
OBJECTIVE: To determine the correlation between the primary implant stability quotient and the implant percussion sound frequency.
METHODS: A total of 14 pigs\' ribs were scanned using a dental cone beam computed tomography (CBCT) scanner to classify the bone specimens into three distinct bone density Hounsfield units (HU) value categories: D1 bone: >1250 HU; D2: 850-1250 HU; D3: <850 HU. Then, 96 implants were inserted: 32 implants in D1 bone, 32 implants in D2 bone, and 32 implants in D3 bone. The primary implant stability quotient (ISQ) was analyzed, and percussion sound was recorded using a wireless microphone connected and analyzed with frequency analysis software.
RESULTS: Statistically significant positive correlations were found between the primary ISQ and the bone density HU value (r = 0.719; p < 0.001), and statistically significant positive correlations between the primary ISQ and the percussion sound frequency (r = 0.606; p < 0.001). Furthermore, significant differences in primary ISQ values and percussion sound frequency were found between D1 and D2 bone, as well as between D1 and D3 bone. However, no significant differences were found in primary ISQ values and percussion sound frequency between D2 and D3 bone.
CONCLUSIONS: The primary ISQ value and the percussion sound frequency are positively correlated.

摘要：
目的：确定主要植入物稳定性商与植入物撞击声音频率之间的相关性。
方法：使用牙科锥形束计算机断层扫描（CBCT）扫描仪扫描了总共14头猪的肋骨，将骨标本分为三个不同的骨密度Hounsfield单位（HU）值类别：D1骨：>1250HU；D2：850-1250HU；D3：<850HU。然后，插入96个植入物：D1骨中有32个植入物，D2骨中有32个植入物，和D3骨中的32个植入物。对主要种植体稳定性商(ISQ)进行了分析，使用连接的无线麦克风记录打击声，并使用频率分析软件进行分析。
结果：发现原发性ISQ与骨密度HU值之间具有统计学意义的正相关（r=0.719；p<0.001），以及主要ISQ与打击声频率之间的统计学显着正相关（r=0.606；p<0.001）。此外，D1和D2骨之间的主要ISQ值和打击声频率存在显着差异，以及D1和D3之间的骨骼。然而,D2和D3骨的原发性ISQ值和打击声频率没有显着差异。
结论：主要ISQ值与打击声频率呈正相关。
