The aim of the present report is first to characterize the extent of bone and soft tissue changes post\u2010extraction and second to identify potential factors influencing tissue preservation in order to facilitate successful treatment outcomes. The facial bone wall thickness has been identified as the most critical factor influencing bone resorption and can be used as a prognostic tool in order to identify sites at risk for future facial bone loss subsequent to tooth extraction. Clinical studies indicated that thin bone wall phenotypes exhibiting a facial bone wall thickness of 1\u00a0mm or less revealed progressive bone resorption with a vertical loss of 7.5\u00a0mm, whereas thick bone wall phenotypes showed only minor bone resorption with a vertical loss of 1.1\u00a0mm. This is in contrast to the dimensional soft tissue alterations. Thin bone wall phenotypes revealed a spontaneous soft tissue thickening after flapless extraction by a factor of seven, whereas thick bone wall phenotypes showed no significant changes in the soft tissue dimensions after 8\u00a0weeks of healing. In sites exhibiting a limited bone resorption rate, immediate implant placement may be considered. If such ideal conditions are not present, other timing protocols are recommended to achieve predictable and pleasing esthetics. Socket preservation techniques for ridge preservation utilizing different biomaterials and\/or barrier membranes often result in a better maintenance of tissue volumes, although the inevitable biological process of post\u2010extraction bone resorption and bone modeling cannot be arrested. In summary, the knowledge of the biological events driving dimensional tissue alterations post\u2010extraction should be integrated into the comprehensive treatment plan in order to limit tissue loss and to maximize esthetic outcomes.<\/jats:p>","DOI":"10.1111\/prd.12167","type":"journal-article","created":{"date-parts":[[2016,12,21]],"date-time":"2016-12-21T03:50:55Z","timestamp":1482292255000},"page":"73-83","source":"Crossref","is-referenced-by-count":359,"title":["Clinical
