However, limited evidence is available for posterior sites. We evaluated the dimensional changes in posterior extraction sockets using four approaches: modified free gingival graft (MFGG); MFGG with xenograft (MFGG\u2009+\u2009XG); guided bone regeneration with titanium membrane and xenograft (TM\u2009+\u2009XG); and unassisted socket healing (USH).<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>Patients requiring posterior tooth extraction were randomly assigned to one of four groups (<jats:italic>n<\/jats:italic>\u2009=\u200922\/group).
