title: Hemorrhage in the floor of the mouth after second-stage surgery: case report.
abstract: Placement of dental implants in the interforaminal region of the mandible is generally considered a routine, simple, and safe procedure. However, severe bleeding and hematoma in the floor of the mouth have been reported as a rare but potentially fatal complication related to the placement of an implant in this region. The following report describes a case of life-threatening hemorrhage in the floor of the mouth after second-stage surgery to place the healing abutment. The implants were forced to match with the prosthesis in a severely atrophic upper jaw, resulting in a perforation of the lingual cortex and mucosa of the floor of the mouth. Clinicians who place implants should be knowledgeable in the treatment of such a serious complication.
