Immediate Functional Rehabilitation of Severely Atrophic Jaws Using Smooth-Surface Single-Piece Corticobasal Implants: A Clinical Case Series

A significant reduction in the alveolar ridge is a known result of prolonged edentulism, advanced gum disease, physical injury, and systemic disorders that affect how bone is built and broken down.The progressive resorption of the alveolar process results in a significant decrease in both the vertical and horizontal dimensions of the bone, thereby undermining the anatomical prerequisites for the stable placement of conventional dental implants.1,2 The resulting alveolar bone deficiency adversely affects implant positioning, prosthetic stability, facial aesthetics, phonetics, and overall oral health-related quality of life.2,3 Conventional rehabilitation of severely atrophic jaws often requires additional bone augmentation methods, such as sinus floor elevation, ridge augmentation, block grafting, and guided bone regeneration.4 Although these procedures have proven effective in clinical settings, systematic investigations indicate they may lead to increased surgical complications, prolonged healing durations, heightened sensitivity to technique, an elevated risk of graft resorption, and extended waiting periods for prosthetic
