Furca Gingiva M

A 58-year-old man requests extraction of the tooth #19 with supraocclusion (Fig.1).  After extraction, the septal gingiva has to be sectioned to remove underlying granulation tissue thoroughly.  The buccal plate is missing.  Ossogen (allograft, Fig.2 *) is placed around the septum (red dashed line).  The socket opening is covered by BioXclude and approximated with 4-0 PGA suture, followed by periodontal dressing.  With the septum's support, bone graft is expected to heal without too much ridge collapse.  The mesial and distal sockets behave as 2 small premolar ones, getting ample blood supply.  The socket heals in 20 days (Fig.3).  The sockets heal with preservation of the septum (Fig.4: S), while there is formation of the cortical plate on the top of the ridge 10 months postop (Fig.5: ^).  It is safe to place a 5x10 mm implant with guide (Fig.6), whereas it may be necessary to place bone graft lingual to the implant at #18 associated with free hand surgery (Fig.7: >).   Return to Lower Molar Immediate Implant, No Deviation 18 种植 位点保存 Xin Wei, DDS, PhD, MS 1st edition 01/22/2020, last revision 07/03/2021
