AuthorsABSTRACTBackground: Osseointegration is a critical determinant of long-term success in both orthopedic and dental implants, yet the underlying mechanisms vary due to differences in biomechanical loading, biological environment, and material interactions. A comparative understanding is required to bridge these domains and enhance translational outcomes. Objective: To comparatively analyze the biological, biomechanical, and material-driven mechanisms of osseointegration in orthopedic and dental implants and identifytranslational strategies for improving implant performance. Methods: A narrative review-based comparative framework was applied to evaluate cellular responses, molecular signaling pathways, surface engineering strategies, and clinical factors influencing osseointegration across implant types. Evidence from experimental, clinical, and material science studies was synthesized to identify common pathways and context-specific variations. Results: Both orthopedic and dental implants have some fundamental biological mechanisms in common, such as protein adsorption, osteoblast differentiation, and bone remodeling. However, unlike orthopedic implants that are mainly subjected to high mechanical loading and require better structural integration, dental implants are exposed to microbial challenges and tissue interactions. Surface engineering techniques such as nano-topography and bioactive coatings have shown promising results in augmenting osteogenic potential and minimizing complications. Translational techniques such as nanotechnology, drug delivery systems, and immunomodulation have shown promising potential in this area. , but differ in their clinical expression due to environmental and mechanical factors. Integrating insights from orthopedic and dental implantology supports the development of advanced biomaterials and personalized therapeutic approaches, improving implant longevity and clinical outcomes. 1. Introduction Osseointegration is described as a direct structural and functional relationship between living bone tissue and the surface of the implant. This is the fundamental basis for the long-term stability and success of the implants. This term was first introduced in dental implantology but has gradually been adapted for use in orthopedic surgery, where the long-term fixation of prosthetic components is critical for the restoration of joint biomechanics and the overall mobility of the patient. Although both types of implants share the need for osseointegration in the formation of a stable bone-implant interface, the biological determinants for this process are unique due to differences in anatomical location and the overall vascular supply to the region as well as the mechanical loading conditions and the overall host response to the foreign body. The early stages of osseointegration occur immediately after the insertion of the implant and are characterized by physicochmical interactions at the interface. Upon contact with blood, proteins such vitronectin, and albumin are rapidly adsorbed onto the as fibrinogen, surface of the implant. This is the provisional fibronectin, extracellular matrix for cell attachment. •••••••••••••••••••••••••••••••• ejprd.org - Published by Riset Publishing Services LLC.
