INTRODUCTIONPostextraction resorption is an irreversible process that causes a reduction in alveolar ridge width and height and, thus, can pose functional and aesthetic challenges for future implant and prosthetic rehabilitation. The resorption rate varies between individuals and between different time intervals within the same individual. Various factors have been reported to influence the resorption process.AIMThis review aims to discuss the factors influencing postextraction alveolar bone resorption and compare their significance.MATERIALS AND METHODSAn electronic search using Web of Science, PubMed, Scopus, and Google Scholar databases was conducted until May 2024. This review includes 40 articles. It summarizes the scientific evidence on the reviewed topic.RESULTSPostextraction resorption depends on numerous system and local factors, the most common of which are the extent of surgical trauma, morphological features of the socket, presence of infection, type and position of the tooth, periodontal biotype, type and time of prosthetic treatment, and some metabolic disorders and bad habits, such as smoking.Further research is necessary to determine how the knowledge of the factors influencing postextraction resorption can be used as a predictive factor for the expected amount of bone loss, and the exact methods that can prevent such resorption, such as ridge preservation, immediate implant placement, etc.CONCLUSIONPostextraction alveolar ridge resorption is an inevitable process that can hinder the implant and prosthetic rehabilitation of the dentition. Understanding the factors influencing this process can assist ridge preservation after tooth loss and the rehabilitation of the dentition
