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.

一种多螺旋深槽螺纹种植体：综述及临床分析。

目的：种植体的成功取决于受宏观几何结构影响的骨整合，包括螺纹设计。螺纹宏观几何在实现初级稳定性方面起着至关重要的作用，特别是在低密度骨中。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Straumann BLX （Straumann Co.）种植体的实践见解。材料和方法：我们在PubMed/MEDLINE和Embase检索到2023年8月之前发表的研究，使用以下关键词：“implant”、“macrogeometry”、“thread”、“thread depth”、“thread pitch”、“thread geometry”、“macrodesign”、“flute”、“osseointegration”和“stability”。此外，我们回顾性地回顾了58例动态螺纹的Straumann BLX种植体，其特点是深螺纹设计，并结合了多螺旋凹槽结构，以增强不同骨密度的主要稳定性。结果：文献表明，螺纹间距、深度和凹槽设计显著影响应力分布和初始稳定性，特别是在低密度骨中。采用深螺纹和螺旋槽植入体可提高植入体的初始稳定性和插入效率。临床上，来自58例病例的回顾性数据支持在具有挑战性的骨条件下，如后上颌和种植体置换部位的良好结果。结论：需要综合考虑骨质量和种植床条件，选择合适的种植体设计。
