Volumetric Assessment of Secondary Alveolar Bone Grafting Using Cone Beam Computed Tomography

Abstract

Secondary alveolar bone grafting of the cleft defect in our center was successful, based on radiographic outcome using cone beam computed tomography scans. Volume rendering using cone beam computed tomography and Amira software is a reproducible and practical method to assess the preoperative alveolar cleft volume and the adequacy of bone fill postoperatively.

Exploring CBCT-Based DICOM Files. A Systematic Review on the Properties of Images Used to Evaluate Maxillofacial Bone Grafts

“…The selected papers included one case report [24] and two prospective (consecutive cases) studies [25,26]. Tables 1, 2, and 3 show the information retrieved from these studies.…”

“…In total, the included papers reported the fate of the graft in 35 patients using CBCT as the evaluation method [24][25][26].…”

“…In one study, autologous bone retrieved from the anterior iliac crest was used as grafting material [26], and one study used a mix of bovine hydroxyapatite and bone allograft [24]. The third study did not report the origin of the grafts [25].…”

“…Two studies had a baseline image to be compared with the final image [24,26], and the only study with a fixed evaluation interval was the case report [24]. One study reported complete information regarding the image acquisition protocols (acquisition time, kilovoltage (kV), miliampere (mA), image resolution, and slice thickness) [25].…”

“…Two studies displayed information on how the orientation plane for generation of image sections was defined, and also how the sections were oriented, and how many sections were evaluated [25,26].…”
