The prosthetic emergence profile is a factor potentially affecting marginal bone level around dental implants. The aim of this review is to provide a comprehensive analysis of the influence of the prosthetic emergence profile on peri-implant marginal bone-level stability. The marginal bone level is an important parameter in implant dentistry, reflecting the stability of dental implants, and it is a critical indicator of long-term implant success. Minimizing marginal bone loss around dental implants is a key factor for maintaining implant function, supporting peri-implant soft tissues, and achieving predictable aesthetic outcomes. The scientific literature presents various examples of evidence on the influence of emergence angle and prosthetic designs on marginal bone loss. Several studies suggest that emergence angles exceeding 30° and convex prosthetic designs may increase the risk of peri-implantitis and bone resorption, while others find no significant correlation. Moreover, several studies demonstrated the positive influence of taper joint connections on marginal bone stability. Although the current literature remains diverse, it is essential to prioritize cleanability and minimize plaque accumulation for a successful implant-prosthetic restoration. Proper maintenance and a continuous follow-up to monitor marginal bone loss are beneficial for obtaining stable and optimal long-term results.
修复体龈缘外形是可能影响牙种植体周围边缘骨水平的一个因素。本综述的目的是全面分析修复体龈缘外形对种植体周围边缘骨水平稳定性的影响。边缘骨水平是种植修复领域的一个重要参数，反映了牙种植体的稳定性，是种植长期成功的关键指标。尽量减少牙种植体周围的边缘骨吸收是维持种植体功能、支持种植体周围软组织并实现可预测美学效果的关键因素。科学文献提供了各种关于龈缘角度和修复体设计对边缘骨吸收影响的证据实例。几项研究表明，超过30°的龈缘角度和凸形修复体设计可能会增加种植体周围炎和骨吸收的风险，而其他研究则未发现显著相关性。此外，多项研究证明了锥形连接对边缘骨稳定性的积极影响。尽管目前的文献仍然存在差异，但对于成功的种植修复体而言，优先考虑清洁性并尽量减少菌斑积聚至关重要。进行适当的维护并持续随访以监测边缘骨吸收，有助于获得稳定且最佳的长期效果。
