This article provides a comprehensive analysis of the biological and biomechanical foundations of osseointegration in dental implantology, its sequential stages, and the key determinants influencing the long-term stability of dental implants. Osseointegration is defined as the process of establishing a firm, functional, and histologically direct connection between the implant material and living bone tissue; therefore, the overall success of implant therapy is directly dependent on this mechanism. The article scientifically elucidates how the regenerative capacity of bone tissue, osteoblastic activity, angiogenesis, the micro- and macro-architecture of the implant surface, its chemical composition, and surface biocompatibility influence the effectiveness of osseointegration. In addition, the impact of patient-related factors—such as general somatic status, age, bone density and quality, metabolic disorders (diabetes mellitus, osteoporosis), harmful habits (smoking), oral hygiene status, inflammatory conditions, and the state of local blood circulation—on the osseointegration process is analyzed separately. The precision of the surgical technique, the degree of bone tissue trauma during implant placement, primary implant stability, the timing of functional loading, and the appropriate selection of the prosthetic protocol are highlighted as essential prerequisites for successful osseointegration. Furthermore, the article discusses modern implant materials, particularly the biocompatibility of titanium and its alloys, as well as the role of surface-modified implants (plasma-sprayed coatings, sandblasting, acid etching, and bioactive coatings) in achieving rapid and strong bone integration, based on current scientific literature. Moreover, the effectiveness of regenerative technologies currently applied to accelerate osseointegration and improve implant success rates—including growth factors and PRF/PRP methods—is also addressed. The findings of this study contribute to optimizing osseointegration in clinical dental implant practice, reducing the risk of complications, and ensuring the long-term functional stability of dental implants. This article has both theoretical and practical significance for dental practitioners, implantologists, and scientific researchers, offering evidence-based approaches aimed at improving implant treatment outcomes.
