Factors influencing post-extraction ridge atrophy

Many factors have been suggested as having an influence on post-extraction ridge atrophy. Among these, the most significant are:

• pre-existing pathological processes that have damaged the bone prior to extraction;
• excessive pressure from a removable prosthesis;
• the presence of a thin bone phenotype;
• the number of missing teeth, that is, the more teeth that are missing, the greater the atrophy.
