Abstract

Because of physiological alterations, alveolar ridge resorption has been thoroughly investigated. Alveolar ridge resorption, a progressive process that cannot be stopped, can happen for a variety of reasons. These aspects include whether a removable dental prosthesis is being utilized, biomechanics pertaining to the functional loading and occlusal forces, and local and/or systemic issues. Regardless of the source of resorption, the reduction in bone availability brought on by its unavoidable progression has a major effect on the bucco-coronal aspect and may make it more difficult to place an implant in the ideal location. so jeopardizing the achievement of acceptable function, appearance, and treatment longevity. A surgical procedure called "ridge augmentation" entails grafting both soft and hard tissues to expand the alveolar ridge's size beyond its initial, insufficient dimensions. Alveolar bone dimensions can be increased both horizontally and vertically using a variety of reconstructive procedures. Usually, these surgeries are performed in cases where there is no sufficient edentulous tissues to support a dental implant.
