AIM The aim of this experimental animal model study is to investigate the effects of caffeic acid phenethyl ester (CAPE) and melatonin on the maturation of newly-formed regenerated bone in distraction osteogenesis. METHODS Unilateral femoral lengthening(extension) was applied to 39 adult male Wistar albino rats, which were randomly allocated to 3 groups of 13; control, melatonin and CAPE grou...
INTRODUCTION: Traditional frontoorbital advancement with a supraorbital bar is the standard technique for correcting coronal craniosynostosis. However, several reports indicate that cranioplasty using distraction osteogenesis can be an alternative. To maximize the advantages of distraction, preservation of the dura attachment to the frontal bone appears to be important. Therefore, we designed a...
The aim of this clinical study is to assess the effectiveness of a new technique of rapid canine retraction through distraction osteogenesis. The effects of dentoalveolar distraction on the dentofacial structures, the dental changes that has been produced by dentoalveolar distraction and the vitality of the distracted canine immediately after distraction and 3 months postdistraction using pulp ...
Vascularized free flaps have become the gold standard in reconstructing large segmental mandibular defects; however, even when bony union and soft-tissue coverage is achieved, insufficient bone stock and altered facial contour can create functional and cosmetic problems for the patient. There have been limited case reports on the use of secondary distraction osteogenesis to address these issues...
The authors describe a new technique for reconstruction of mandibular body defects. The feasibility of distraction osteogenesis with submerged (internal) devices for reconstruction of segmental mandibular defects is investigated in an experiment with five adult dogs. A segmental mandibulectomy was performed on the horizontal ramus. The bony defect was regenerated using distraction osteogenesis ...
BACKGROUND Lengthening the maxillary dental arch as a treatment approach for patients with maxillary deficiency and dental crowding is seldom reported. The purpose of this study was to assess dental and skeletal changes in the maxilla in the correction of maxillary deficiency associated with a retruded maxillary arch using a surgically assisted rapid maxillary anterior-posterior expansion appli...
PURPOSE In vitro data were collected to measure torque-force values of an internal distraction device. The measurements were correlated with in vivo torque readings in an attempt to better understand the force required to distract the osteogenic bone callus of the human mandible during distraction osteogenesis. METHODS AND MATERIALS Five internal craniofacial distraction devices were mounted ...
PURPOSE To demonstrate our experience using internal devices for unidirectional distraction osteogenesis in treating different mandibular hypoplasias (with or without maxillary deformities). An algorithmic table for diagnosis, and treatment planning is presented. PATIENTS AND METHODS Twenty internal distraction devices were used in 16 patients with mandibular hypoplasia. Deficiency in length ...
background: current methods of closure of the cleft palate result in the formation of scars and impairment of growth. distraction osteogenesis (do) might be an effective means to repair or at least reduce the size of wide clefts. this study investigates the biomechanical aspects of this process. materials and methods: do simulation was applied to reduce the size of a unilateral hard palate clef...
