Abstract
Tantalum dental implants have emerged as a promising alternative to conventional titanium implants, offering superior biocompatibility, osteoconductivity, and enhanced osseointegration. The distinctive properties of tantalum, particularly its highly porous trabecular structure, closely mimic the natural architecture of bone and facilitate optimal bone ingrowth and vascularization. This porosity creates an ideal environment for osteocyte infiltration and cellular attachment, promoting robust bone-implant integration, which is essential for long-term implant stability and success. Despite these advantageous biological properties, several significant challenges limit the widespread clinical adoption of tantalum dental implants. The high cost of raw tantalum material, and the requirement for specialized fabrication techniques - such as chemical vapor deposition and powder metallurgy - pose substantial economic and technical barriers. Additionally, the paucity of long-term clinical data, concerns regarding potential material degradation in the oral environment, and complexities in implant design optimization remain unresolved. While preliminary clinical studies demonstrate encouraging outcomes, comprehensive research is imperative to address these limitations and establish evidence-based protocols. This review critically examines the current state of tantalum implants in dental practice and provides insights into their potential role in advancing modern implantology.
