Hard and soft tissue measurements of the extraction site were obtained pre\u2010extraction and were repeated 6\u20138\u00a0weeks post\u2010extraction at defined points using a key.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>After a 6\u2010 to 8\u2010week healing period, the total ridge thickness in the crestal midline reduced by 15% of the original value.
