RESUMEN

Distraction osteogenesis is a biologic process of new bone formation, between the surfaces of bone segments that are gradually separated by incremental traction. This method of providing additional bone and soft tissue for implant placement is becoming more common. This clinical report describes the use of distraction osteogenesis and a fixed implant-supported prosthesis to treat a premaxillary defect. A major esthetic concern with alveolar distraction osteogenesis is obtaining a predictable position of the transosteal portion of the implant in relation to the newly generated bone ridge crest. Additional clinical and experimental studies are needed to provide guidelines for predictable esthetic outcomes. (J Prosthet Dent 2008; 100:250-253)

SUMMARY

Alveolar DO is becoming an established method of providing additional hard and soft tissue to sites requiring dental implants. The fixed restoration of an anterior maxilla and the esthetic problem that was encountered due to the unpredictable final bony ridge crest position were described. Additional clinical studies are needed to provide guidelines for predictable esthetic outcomes.
