The purpose of this study was to evaluate the relationship between subjective bone quality assessments and objective implant stability values using Periotest and Osstell Mentor, which are widely used clinically, to assess the correlation between these 2 measurements.
A total of 211 dental implants (114 in the maxilla and 97 in the mandible) were placed in 162 patients (89 males and 73 females). Bone quality type was classified according to the Lekholm and Zarb classification. After implant placement, implant stability was measured using Periotest and Osstell Mentor. Implant stability was represented by the implant stability quotient (ISQ) values and periotest values (PTVs). All of the procedures were performed by 1 operator to reduce potential errors.
The ISQ values were higher in the mandible (72.77 ± 8.77) than in the maxilla (65.72 ± 8.65), whereas PTVs were lower in the mandible (-3.02 ± 2.63) than in the maxilla (-0.17 ± 2.82). A statistically significant correlation was found between bone quality type and both ISQ values and PTVs. A significant negative correlation was found between the ISQ values and PTVs (P < .01).
Both measurements seem to be useful in predicting implant placement prognosis and in determining loading protocols.
本研究旨在评估使用广泛应用于临床的 Periotest 和 Osstell Mentor 评估主观骨质量评估与客观种植体稳定性值之间的关系，以评估这两种测量方法之间的相关性。
共将 211 枚种植体（上颌 114 枚，下颌 97 枚）植入 162 名患者（男性 89 名，女性 73 名）中。根据 Lekholm 和 Zarb 分类法对骨质量类型进行分类。种植体放置后，使用 Periotest 和 Osstell Mentor 测量种植体稳定性。种植体稳定性用种植体稳定性指数（ISQ）值和 Periotest 值（PTV）表示。所有操作均由一名操作人员进行，以减少潜在误差。
下颌的 ISQ 值（72.77±8.77）高于上颌（65.72±8.65），而下颌的 PTV 值（-3.02±2.63）低于上颌（-0.17±2.82）。骨质量类型与 ISQ 值和 PTV 值均存在显著相关性。ISQ 值与 PTV 值之间存在显著负相关（P<0.01）。
这两种测量方法似乎都可用于预测种植体植入预后，并确定加载方案。
