A comprehensive review of current literature, including clinical studies, legal rulings, and malpractice claims, was conducted to assess the legal implications of immediate loading implantology. The analysis focused on professional liability, patient consent, and complications during treatment. The evidence indicates that a high standard of care, including detailed preoperative planning, risk assessment, and clear patient communication, is essential in minimizing legal risks. Malpractice claims often arise from inadequate patient information or failure to follow established protocols. Proper documentation of informed consent and adherence to evidence-based dentistry (EBD) guidelines are crucial to protect both patients and practitioners. Immediate loading implantology offers numerous benefits, but it requires meticulous planning and patient management to avoid medico-legal issues.
