Alveolar ridge augmentation by distraction osteogenesis using titanium implants: an experimental study

Vertical distraction of the severely resorbed mandible

“…This observation is in agreement with data of Samchukov et al (1999). In a dog study, at 52 weeks after distraction, it has been shown that the thickness of the cortical bone in the distraction zone is slightly thinner than that of native cortical bone (Oda et al 1999).…”

“…Possible complications of the distraction procedure are fracture of the mandible, wound dehiscence and nerve disturbance (Gaggl et al 2000). Other complications might occur like osteomyelitis, lack of bone formation and bone resorption of the superior segment (Oda et al 1999). The last two complications may be due to the severely resorbed mandible with its poor blood supply.…”

“…Preliminary studies in animals have shown the very good quality of generated bone, with adequate potential for implant osseointegration (Block et al 1996(Block et al , 1998Oda et al 1999Oda et al , 2000. To the best of our knowledge no studies in humans are available in the literature evaluating the formation of new bone induced by vertical distraction of the severely resorbed anterior mandible.…”

Influence of periosteal coverage on the osteointegration and stability of dental implant distractors

“…Sub-periosteal dissections and corticotomies are usually required for the installation of the distractor device in conventional distraction osteogenesis (Perdijk et al 2009). However, the importance of periosteum preservation has been espoused by various authors who observed that new bone formation was greater over the lingual than buccal distraction region, presumably due to the greater amount of damage to the buccal periosteum (Sawaki et al 1996;Oda et al 1999). Another proponent for periosteal preservation was the increased resorption of the bony regenerate in instances where the osteotomized transport segment was too small or when a full mucoperiosteal flap was elevated (Oda et al 1999).…”

The Segmental Down Fracture for Vertical Bone Augmentation: Case Report

“…[1][2][3][4][5] More recently, distraction osteogenesis has been described with very impressive results. [6][7][8][9] The purpose of this article is to present another approach to the problem of insufficient bone height using a technique commonly used in orthognathic surgery. The procedure is known as a segmental down fracture.…”
