ABSTRACT
<p><b>OBJECTIVE</b>To investigate restoration of alveolar cleft with engineered bone constructed by sponge collagen protein combined bone mesenchymal stem cells (BMSC).</p><p><b>METHODS</b>Twelve dogs were divided into 4 groups, the third incisor and alveolar bone with periosteum in bilateral maxilla were removed to form alveolar cleft model. The BMSCs were isolated from dog bone marrow. After being cultured and induced, the BMSCs were seeded in sponge collagen protein and cultured for 48 hours. The composites of BMSCs and collagen were implanted into the defect of alveolar cleft. After 12 weeks' feeding, those dogs were sacrificed. Three-dimensional CT and histological examination were used to observe the progress of bone formation.</p><p><b>RESULTS</b>The defects healed at 12 weeks after being implant BMSCs-collagen composites, the width of engineered bone is resembled with positive control, but the height is less than positive control.</p><p><b>CONCLUSIONS</b>The engineered bone can restore the defect of alveolar bone effectively, it can be used clinically to treat alveolar cleft.</p>
