The aim of this study was to provide a critical appraisal based on a systematic review of the single\u2010rooted extraction socket (ES) classifications and subsequently, introduce a new classification system combining the cornerstones of the previously proposed systems and based on the latest consensus in implant dentistry. Following the systematic search process in PubMed, EMBASE, and SCOPUS databases 13 ES classifications were detected. The most repeated hard and soft tissue factors in the previous classifications were buccal bone dehiscence, interproximal bone, gingival recession, and soft tissue phenotype. However, there was minimal attention to patient\u2010related factors such as systemic conditions and smoking. Therefore, a new classification system based on the combination of patient\u2010related factors, clinical and radiographical parameters was proposed. This divides an ES into three types. Class I and II sockets are candidates for receiving immediate implant placement and conversely, a class III socket includes a compromised condition that requires multiple\u2010stage reconstruction mostly suitable for standard delayed implant placement with alveolar ridge preservation. Within the limitations of this study, the new classification system not only provides comprehensive inclusion of various crucial parameters in implant placement (such as prediction of future implant position and osteotomy difficulty, etc.) but also, in contrast to the previously introduced systems, is able to classify the ES prior to extraction and also, takes into the account the patient\u2010related factors as the class modifiers following the extraction.<\/jats:p>","DOI":"10.1111\/jerd.12967","type":"journal-article","created":{"date-parts":[[2022,10,5]],"date-time":"2022-10-05T11:15:16Z","timestamp":1664968516000},"page":"168-182","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":23,"title":["<scp>Single\u2010rooted<\/scp>
