The occlusion of dental implants is a critical area that connects biomechanics with clinical decision-making. Unlike natural teeth, implants lack a periodontal ligament and adaptive mobility, which increases susceptibility to occlusal overload and mechanical complications. This seminar reviews core biomechanical principles for implant occlusion, including axial load distribution, occlusal scheme selection and adjustment, and management of functional occlusal forces, with emphasis on widely accepted guidelines for implant occlusion. These concepts are then contrasted with the realities of practice, such as anatomical limitations and the presence of adjacent natural teeth that share or modulate load. Through practical cases and force analysis, we illustrate how ideal recommendations are adapted to individual cases, and how to prioritize axial contacts, minimize lateral shear, and calibrate occlusal contacts to enhance longevity and function. The goal is to achieve a clear,
clinically actionable approach that aligns precision engineering with biologic response, enabling. dentists to deliver stable, comfortable, and durable implant-supported restorations.
