Long-term Follow-up of Implant Installation Following Multiple Distraction Osteogenesis in Maxillofacial Gunshot Wounds.

ABSTRACT

Distraction osteogenesis (DO) is a reconstruction technique developed in the fields of oral and maxillofacial surgery and plastic surgery, addressing both vertical and horizontal bone deficiencies and enhancing soft tissue volume to facilitate subsequent dental implant placement. In this treatment method, devices are placed to stretch the bone gradually to stimulate the formation of new bone, effectively filling the existing defect to treat maxillofacial deformities or repair posttraumatic injuries. This case report presents an almost 20-year long-term follow-up of jaw defect reconstruction resulting from a gunshot injury, using DO with multiple distractors. Details on the frequency, period of DO, and subsequent implant installation in the distracted anterior jaw area are outlined. This case exhibits DO treatments that reconstructed effectively severe bone defects in the jaws. The quality of bone generated during the DO process was both functionally and esthetically satisfactory for subsequent implant rehabilitation.
