The conventional “Crown Removal First” strategy was applied in the TM group
In TM group, as the crown was removed prior to the root(s), the incision and the creation of a bony window should be designed accordingly to allow sufficient exposure of the the crown of the IMTM. The wound care was the same as we have described in the NM group.Standard postoperative care and instructions were given to both groups of patients routinely. Patients were instructed to remove the sutures at the second follow-up appointment (day 7).
