Implant-Prosthetic Rehabilitation of Mandibular Posttraumatic Severe Dentoalveolar Loss With a Reconstructive Staged...

This clinical report describes the oral rehabilitation of a 25-year-old male patient who lost the lower incisors, right canine, and a significant amount of anterior mandibular bony and soft tissue following severe dentoalveolar trauma due to a car accident. The patient's young age, anterior esthetic zone in the lower jaw, previous mandibular fracture, and extended bony and soft-tissue defect hindering ideal 3-dimensional implant placement oriented the therapeutic plan toward a staged approach, with several reconstructive surgical procedures before implant rehabilitation. The treatment involved deepening the labiobuccal vestibule and lingual sulcus to correct cicatricial shrinkage due to previous surgical fixation of the mandibular fracture, vertical guided bony augmentation to regenerate adequate volumes of bone, free gingival graft to achieve sufficient height and thickness of peri-implant soft tissues, and a prosthetic-driven surgical procedure to place the implants in a good functional and esthetic position. This therapeutic approach restored function and esthetics and achieved outcome stability at 3-year follow-up.
