Abstract

Basal implantology, also referred to as corticobasal implantology, strategic implantology, or bicortical implantology, is an advanced implant rehabilitation concept that utilizes the dense cortical bone of the maxilla and mandible for implant anchorage rather than the resorbable alveolar bone. Basal implants achieve primary stability through osseofixation in the cortical bone. This principle enables immediate functional loading, often within 72 hours, while avoiding additional procedures such as sinus floor elevation, guided bone regeneration, and block bone grafting. The concept of basal implantology has evolved considerably since the development of the first single-piece implant by Dr. Jean-Marc Julliet in 1972. Subsequent innovations by Dr. Gérard Scortecci and Prof. Stefan Ihde led to the development of modern Basal Osseointegrated (BOI), Basal Cortical Screw (BCS), and KOS implant system. This review summarizes the biological basis, historical development, biomechanical principles, implant designs, surgical protocols, indications, contraindications, prosthetic considerations, and current clinical evidence related to basal implantology. Recent advances in digital implant planning, CAD/CAM prostheses, and finite element analysis are also discussed.
