Segment Distraction to Reduce a Wide Alveolar Cleft Before Alveolar Bone Grafting

Abstract

In patients with a wide alveolar cleft, soft tissue coverage with keratinized mucosa can be more readily assured by reducing the alveolar cleft by callus distraction to mesialize the lateral segment prior to bone grafting.

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

“…This method utilizes DOG, and is therefore also frequently employed in the craniofacial area 4,7,13,14,16) . Another advantage of IDO is that it can extend not only bone, but also surrounding soft tissues such as periosteum, muscles, nerves, blood vessels, skin and mucosa 1) . It can be used in patients requiring greater distraction compared with conventional jaw surgery, and there is little postoperative relapse because the extended area becomes compact bone.…”

“…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.…”

“…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.…”

Dudak damak yarıklı hastalarda alveoler distraksiyon osteogenez uygulamaları: literatür derlemesi

“…Geniş alveol yarığına sahip hastalarda alveolar DO uygulanarak alveol yarığın kapandığı veya genişliğin azaltıldığı ve ortodontik tedavinin de daha kolay hale geldiği belirtilmektedir. [3][4][5] Bu derlemenin amacı, bu spesifik hasta grubunda uygulanabilecek alternatif tedavi metodlarından biri olarak alveolar DO uygulamalarını yapılan çalışmaların ışığında değerlendirmek; DO histogenezisini, uygulamanın endikasyonlarını, avantaj ve dezavantajlarını, uygulama metodlarını, bu amaçla kullanılan aparey çeşitlerini ve bu apareylerin avantaj ve dezavantajlarını belirlemektir. …”
