BACKGROUND AND PURPOSE: Although @entity2419 bone grafting is the most widely accepted approach, controversies remain on the operative timing. METHODS: A consecutive retrospective series of 28 @entity1 who received alveolar bone grafting was examined and divided into 2 groups depending on the age at the time of bone graft. Group A (14 @entity1 ) was operated at a mean age of 5.2 years [range, 4-7] and Group B (14 @entity1 ) at a mean age of 10 years [range, 8.5-13]. All the @entity1 were assessed clinically and by Cone Beam Computed Tomography (CBCT) before bone grafting and 6 months post-operatively. Cleft and bone graft dimensions, volumes were assessed using Osirix v.3.9.2. Residual bone graft coefficient (Bone Graft Volume on 6-months Postoperative CBCT/Alveolar Cleft Volume) was calculated. Complications, tooth movement or dental agenesis were also reported. RESULTS: The sample was uniform within both groups, considering cleft forms, pre-surgical @entity292 rate and cleft volume. Residual bone graft coefficient reached 63.3% in Group A and 46.2% in Group B (p  =  0.012). Results of residual bone graft are also influenced by tooth eruption through the graft (p  =  0.007 in Group A and p  =  0.02 in Group B). CONCLUSIONS: This 3D analysis highlighted higher success of alveolar bone grafts when @entity1 are operated earlier around 5 years. LEVEL OF EVIDENCE: Therapeutic study. Level III/retrospective comparative study.
