AuthorsAbstractDental implant success is fundamentally dependent on effective osseointegration, a process governed by complex interactions between implant surfaces and the biological environment. Over recent decades, significant advancements in surface engineering have transformed implant design from passive structural components to biologically active systems that actively promote bone integration and long-term stability. This review provides a comprehensive overview of emerging dental implant surface technologies and their role in enhancing osseointegration. Surface modifications at micro- and nano-scales have been shown to significantly influence protein adsorption, cellular adhesion, and osteogenic differentiation. Techniques such as sandblasting, acid etching, anodization, plasma treatment, and laser texturing have improved surface roughness, wettability, and energy, thereby enhancing early healing responses. In addition, bioactive and functionalized surfaces incorporating antimicrobial agents, growth factors, and immunomodulatory materials have demonstrated the ability to simultaneously promote bone formation and reduce the risk of peri-implant infections. Advancements in manufacturing technologies, including additive manufacturing and sol–gel coatings, have enabled the development of customized and multifunctional implant surfaces. Furthermore, alternative biomaterials such as zirconia and polyetherketone have expanded the scope of implant applications, offering improved aesthetic and mechanical properties. Preclinical and clinical evaluations consistently indicate that optimized surface characteristics lead to improved bone-to-implant contact and long-term implant stability. Despite these advancements, challenges remain in standardizing surface modification techniques and translating experimental findings into clinical practice. Future directions focus on the development of smart, biomimetic, and patient-specific implant surfaces to further enhance clinical outcomes. 1. Introduction The fundamental biological mechanism by which dental implants perform well and can be referred to as the basic mechanism of dental implant success is known as the process of Osseointegration, which involves a direct straight stable interface of the living bone and dental implant surface devoid of the formation of an intervening soft tissue [1]. The long-term success of implant therapy has been significantly increased during the past several decades, though even in physiological and pathological states, the stability of the bone-implant interface is the key to success. Poor osseointegration failures have remained clinical problems that continue to exist today in the form of patients with compromised systemic health or bone quality. Peri-implant diseases, especially peri-implantitis disase is regarded as a leading cause of implant failure and is directly associated with the colonization by microbes and reactions of the host immune system [2]. Biofilms of pathogens that develop on the surface of implants have an impact on the local bone homeostasis which in turn trigger inflammatory cascade that induce local bone loss. This is a two-fold task of achieving rapid osseointegration and inhibiting bacterial attachment which has sparked a lot of research on how best to modify the nature of the dental implants surface. •••••••••••••••••••••••••••••••• ejprd.org- Published by Riset Publishing Services LLC.
