Abstract

OBJECTIVES

Implant success depends on osseointegration that is influenced by macrogeometry, including thread design. Thread macrogeometry has a crucial role in achieving primary stability, particularly in low-density bone. Our study reviews the thread design's impact on implant stability, focusing on Straumann BLX (Straumann Co.) implants for practical insights.

MATERIALS AND METHODS

We searched the PubMed/MEDLINE and Embase for studies released until August 2023 using the following keywords: "implant", "macrogeometry", "thread", "thread depth", "thread pitch", "thread geometry", "macrodesign", "flute", "osseointegration", and "stability". In addition, 58 Straumann BLX implants with dynamic threads, which feature a deep thread design and incorporate a multi-helix flute structure to enhance primary stability across different bone densities, were reviewed retrospectively at our institute.

RESULTS

The literature demonstrated that thread pitch, depth, and flute design significantly affect stress distribution and initial stability, especially in low-density bone. Implants with deep threads and spiral flutes showed improved primary stability and insertion efficiency. Clinically, retrospective data from 58 cases supported favorable outcomes in challenging bone conditions such as posterior maxilla and implant replacement sites.

CONCLUSION

We need to determine appropriate designs for implants with the consideration of bone quality and implantation bed condition.

摘要

目的

种植体的成功取决于骨结合，而骨结合会受到包括螺纹设计在内的宏观几何形状的影响。螺纹宏观几何形状在实现初期稳定性方面起着关键作用，尤其是在低密度骨中。我们的研究回顾了螺纹设计对种植体稳定性的影响，重点关注士卓曼BLX（士卓曼公司）种植体以获取实际见解。

材料与方法

我们在PubMed/MEDLINE和Embase数据库中检索截至2023年8月发布的研究，使用以下关键词：“种植体”、“宏观几何形状”、“螺纹”、“螺纹深度”、“螺距”、“螺纹几何形状”、“宏观设计”、“凹槽”、“骨结合”和“稳定性”。此外，我们对本机构的58枚具有动态螺纹的士卓曼BLX种植体进行了回顾性研究，这些种植体具有深螺纹设计，并采用多螺旋凹槽结构以增强在不同骨密度下的初期稳定性。

结果

文献表明，螺距、深度和凹槽设计显著影响应力分布和初期稳定性，尤其是在低密度骨中。具有深螺纹和螺旋凹槽的种植体显示出更好的初期稳定性和植入效率。临床上，58例的回顾性数据支持在诸如上颌后牙区和种植体置换部位等具有挑战性的骨条件下取得良好结果。

结论

我们需要根据骨质量和植入床条件来确定种植体的合适设计。
