Role of Hydroxyapatite graft and Barrier membrane in Alveolar ridge augmentation: A Review

Abstract

Ridge augmentation, a critical procedure in modern dentistry, aims to restore the integrity and dimensions of the alveolar ridge after the extraction of tooth which resulting in loss of bone. Hydroxyapatite, a bioactive mineral renowned for its resemblance to natural bone, has emerged as a valuable material for enhancing ridge augmentation outcomes. Hydroxyapatite serves as an effective bone graft substitute and scaffold in ridge augmentation procedures. Its biocompatibility and osteoconductivity facilitate the regeneration of new bone tissue, promoting integration with the host bone. When applied within extraction sockets or over implant surfaces, hydroxyapatite mitigates bone resorption, preserving the alveolar ridge's structural integrity and facilitating successful dental implant placement. Furthermore, hydroxyapatite coatings on implant surfaces enhance osseointegration, contributing to long-term implant stability and functionality. In guided bone regeneration, hydroxyapatite combines with barrier membranes to create a conducive environment for bone regrowth while preventing soft tissue interference. Its porous structure facilitates cellular adhesion and vascularization, crucial factors for efficient bone formation. This abstract underscores the pivotal role of hydroxyapatite in ridge augmentation, underlining its potential to revolutionize dental implantology by offering a biocompatible and biomimetic solution for optimal alveolar ridge restoration.
