Brief summary
This randomized clinical trial evaluated whether adding autologous bone marrow aspirate concentrate (BMAC) to a bovine-derived bone graft improves healing and bone regeneration in patients undergoing reconstruction of a unilateral alveolar cleft. Sixteen participants were randomly assigned in a 1:1 ratio to receive either bovine bone graft combined with BMAC or bovine bone graft alone. Participants were followed for 6 months. Clinical assessments included postoperative pain, soft-tissue healing, fistula recurrence, and tooth eruption. Radiographic assessments included alveolar bone level, CT-derived graft radiodensity, and three-dimensional volumetric measurements of graft integration, resorption, and defect fill.
Detailed description
This prospective randomized controlled clinical trial was conducted at the Department of Oral and Maxillofacial Surgery, Faculty of Dentistry, Tanta University. The study investigated the clinical and radiographic effectiveness of bone marrow aspirate concentrate (BMAC) combined with a bovine-derived particulate bone graft for reconstruction of unilateral alveolar cleft defects. Eligible participants were randomly allocated in a 1:1 ratio to either the study group or the control group using a simple lottery method. Participants in the study group received bovine-derived particulate bone graft combined with autologous BMAC, whereas participants in the control group received bovine-derived bone graft without BMAC. For the study group, BMAC was mixed with the bovine graft at a ratio of 1 mL of BMAC per 1 cc of graft approximately 10 minutes before implantation. The interval was used as a standardized procedural step to allow contact and wetting of the graft particles and was not considered a biologically validated incubation period. Both groups underwent standardized alveolar cleft reconstruction and were followed for 6 months. Clinical evaluation included postoperative pain, soft-tissue healing, fistula recurrence, and tooth eruption. Radiographic evaluation included assessment of alveolar bone level using the Chelsea scale, CT-derived graft radiodensity, and three-dimensional volumetric analysis to assess graft integration, graft resorption, and effective defect fill.
Interventions
Autologous bone marrow aspirate concentrate (BMAC) was prepared from bone marrow aspirated from the anterior iliac crest and combined with bovine-derived particulate bone graft. BMAC was mixed with the graft at a ratio of 1 mL per 1 cc approximately 10 minutes before implantation into the alveolar cleft defect.
The unilateral alveolar cleft defect was reconstructed using bovine-derived particulate bone graft without the addition of BMAC.

|---|---|---|
| Graft Take at 6 Months | 6 months after surgery | Graft take was assessed using three-dimensional CT-derived volumetric analysis. It was calculated as the percentage of the grafted volume that remained integrated within the reconstructed alveolar cleft at the 6-month follow-up. |
Secondary
| Measure | Time frame |
|---|---|
| Soft-Tissue Healing | 6 months after surgery |
| Nasal Regurgitation/Oronasal Fistula Recurrence | 6 months after surgery |
| Tooth Eruption | 6 months after surgery |
| Graft Resorption at 6 Months | 6 months after surgery |
| Effective Defect Fill at 6 Months | 6 months after surgery |
| Integrated Graft Volume at 6 Months | 6 months after surgery |
| Chelsea Scale Bone Level Assessment at 6 Months | 6 months after surgery |
| CT-Derived Graft Radiodensity at 6 Months | 6 months after surgery |
