Objectives: To review clinical indications, biological considerations, and outcomes associated with conventional and immediate implant loading protocols and to highlight factors influencing successful osseointegration. Methods: A narrative review of current literature was performed focusing on implant stability, bone quality, implant surface characteristics, occlusal loading patterns, prosthetic design, and healing protocols. Comparative outcomes of immediate, early, and conventional loading strategies were analyzed to identify optimal clinical applications. Results: Conventional loading demonstrated predictable osseointegration with delayed functional loading, while immediate loading offered reduced treatment time and improved patient satisfaction. Advances in implant surface modification and macrodesign contributed to enhanced primary stability and accelerated healing. However, variability exists in reported marginal bone loss and long-term survival outcomes across loading protocols. Conclusions: Immediate loading can be successfully implemented in selected cases with adequate primary stability and favorable bone conditions. Conventional loading remains the gold standard for compromised clinical situations. Individualized case selection is critical for optimizing implant success.
