A Comparative Volumetric Assessment of Cancellous and Cortico-Cancellous Bone Graft in the Management of Unilateral Alveolar Cleft Defect using Cone Beam Computed Tomographic Scan-A Randomized Controlled Trial.

Introduction: The most commonly preferred procedure for surgical correction of alveolar bone defect and restoration of bony contour is anterior iliac crest graft. Since the ancient time, cancellous bone graft is considered as a gold standard, but it has a high resorption rate and many other disadvantages, and hence we conducted this study to evaluate the efficacy of Cortico-cancellous bone graft harvested from anterior iliac crest to find out whether it can be used as a substitute for cancellous bone graft or not.

Aims & Objectives: The objectives of present study were to compare and evaluate the bone bridge formation rate, resorption rate, and uptake of bone graft at recipient site using cancellous and corticocanellous bone graft harvested from anterior iliac crest for complete unilateral cleft alveolus defects.

Evaluation of maxillary alveolar ridge formation and ridge continuity after secondary alveolar bone grafting using cancellous and cortico-cancellous bone graft in unilateral cleft alveolus using cone beam computed tomographic scan - a randomized controlled trial.

Purpose: The aim of present study was to compare and evaluate the maxillary alveolar ridge formation and ridge continuity using cancellous and corticocanellous bone graft harvested from anterior iliac crest for complete secondary unilateral cleft alveolus defects.

Material And Method: All patients were randomized into two groups for secondary alveolar bone grafting. Group I (n = 10) patients treated with cancellous particulate bone graft and group II (n = 10) patients treated with cortico-cancellous block graft.

Qualitative assesement of newly formed bone after distraction osteogenesis of mandible in patients with facial asymmetry using 3 dimensional computed tomography.

Introduction: Distraction osteogenesis is a surgical technique of new bone formation between the osteotomized bone segments with the help of gradual incremental traction. As distraction osteogenesis is slow biologic process, soft tissue changes gradually follow the new bone formation. Mandibular distraction is one of the accepted modalities to treat the triad of TMJ ankylosis, obstructive sleep apnoea & micrognathia and also for facial asymmetry cases like hemifacial microsomia, mandibular hypoplasia etc.
