Distraction osteogenesis using a longitudinal corticotomy

Differences in mandibular distraction osteogenesis after corticotomy and osteotomy.

Corticotomy or osteotomy was performed on opposing sides of the mandibles in 18 goats. A custom-made distractor was used to lengthen the mandible at a rate of 1 mm/day for 10 days (total 10 mm elongation). Six goats were sacrificed respectively at 2, 4 and 8 weeks after completion of distraction. The distracted calluses were harvested and processed for radiographic, histologic, and scanning ele...

Pattern of Cortical Fracture following Corticotomy for Distraction Osteogenesis

Corticotomy is an essential procedure for deformity correction and there are many techniques described. However there is no proper classification of the fracture pattern resulting from corticotomies to enable any studies to be conducted. We performed a retrospective study of corticotomy fracture patterns in 44 patients (34 tibias and 10 femurs) performed for various indications. We identified f...

Distraction Osteogenesis

Distraction osteogenesis is increasingly used for bone lengthening of facial skeleton. Distractors may be intraoral and extraoral. The authors present development of distractors and their use for treatment of facial bones. Procedure may be used for treatment of malformations, syndroms, posttraumatic bone defects and deformities. The advantage of a distractor are a simple and fast procedure, sho...

Distraction Osteogenesis

Distraction Osteogenesis

Distraction osteogenesis is a treatment modality for the correction of bone anomalies and abnormalities which are either pathological or developmental in origin. Its use in the field of dentistry began in the late twentieth century. Successfulresults from clinical trials has led to more researchers to explore this field. Its use in dentistry involves the correction of craniofacial anomalies, al...
