Objective:To investigate the clinical effect of titanium mesh combined with autologous iliac cancellous bone graft on the alveolar cleft repair. Methods:This study included 13 patients with alveolar cleft

who were treated with titanium mesh

autologous iliac cancellous bone. At 6 months after operation

the healing of the operative area was assessed

and the osteogenic effect was observed by cone-beam computed tomography; the osteogenic effect was evaluated by the lowest marginal bone level（MBL）

the shortest vertical length of bone bridge（SLB）

the shortest anteroposterior bone width（SBW）

graft survival rate

and the success rate of grafting. Results:After operation

12 cases had good primary healing without infections

graft exposure

and other complications in the operative area; 1 case failed due to wound dehiscence and infection at 2 days postoperatively. At 6 months after operation

MBL was（2.61 ± 0.34）mm

SLB was（8.50 ± 0.52）mm

SBW was（3.67 ± 0.46）mm

the graft survival rate was92.31%

and the success rate of grafting was 84.61%. Conclusion:Titanium mesh combined with autologous iliac cancellous bone graft is a reliable method for alveolar cleft repair due to high success rate and good morphological and functional recovery.
