Dental implants have become an essential component of modern restorative dentistry, offering a predictable and long-lasting solution for tooth replacement. Their widespread acceptance is attributed to high success rates, preservation of alveolar bone, and improved esthetics and function. This review aims to provide a comprehensive overview of the foundational principles in implantology, covering the biological basis of osseointegration, anatomical considerations, implant types, assessment methods, surgical protocols, prosthetic planning, and future innovations. Emphasis is placed on the importance of thorough treatment planning, appropriate case selection, and a multidisciplinary approach to ensure optimal outcomes. This paper serves as a practical guide for clinicians seeking to strengthen their understanding of implantology and apply evidence-based protocols in clinical practice.
