Maxillary bone transportation in alveolar cleft—transport distraction osteogenesis for treatment of alveolar cleft repair

Alveolar distraction osteogenesis: a systematic review

“…This permits shortening of the overall treatment period and earlier placement of implants 11,25 , which show success rates comparable to implants placed in native alveolar bone 6,9 . DO has also been applied (a) for vertical augmentation of the alveolar ridge following failed grafting procedures 2,33 and bone following grafting 7 , (b) segmentally, prior to orthognathic surgery 65 , (c) for anterior advancement in maxillary hypoplasia 17 and (d) horizontally for closure of alveolar clefts 44,74 .…”

Application of Interdental Distraction Osteogenesis to Unilateral Cleft Lip and Palate Patients

“…Bone-bone 1,15) , bone-tooth 11,21) , and toothtooth 5,19) types of distraction devices have been reported. Because bone-bone and bone-tooth type distraction devices are firmly fixed, there is no need to take into account their side effect on teeth used for fixation as seen in the tooth-tooth type.…”

“…Reported distraction protocols comprise a latency period of from 3 5,11) to 6 days 1,19) and distraction speeds of 0.5 mm/day 1,5,15,19) , or 1.5 mm in the first week, 1 mm in the second week, and 0.5 mm in the third week 11) . We decided on a latency period of 7 days in light of the wound openings along the incision lines, and performed a 0.5 mm distraction twice a day, in the morning and evening.…”

“…With respect to the treatment of persistent bone defects at the alveolar cleft site following IDO, Mitsugi et al 15) stripped away the mucosa at the docking site under local anesthetic when removing the distraction device, promoting the formation of a bone bridge by transportation of the bone generated by DOG. Sakamoto et al 18) promoted bone formation by filling the gap with ␤-tricalcium phosphate (␤-TCP), platelet-rich plasma (PRP), and bone marrow aspirate.…”

“…Bone transport is a method of bone reconstruction that involves performing partial segmental osteotomy of the bone fragment of the segmental defect and extending this segment towards the fragment on the other side. Interdental distraction osteogenesis (IDO) is carried out by applying the principle of bone transport to the alveolar cleft defect in patients with cleft lip and palate 1,5,11,12,15,18,19,21) . Here, we report the application of DOG with the aim of reducing the width of the alveolar cleft in patients with cleft lip and palate who had wide alveolar clefts by IDO of maxillary alveolar bone in addition to orthodontic treatment, whereby we achieved good results.…”
