The aim of the study is to enhance the maxillary segments stability during graft healing using microplate fixation to be compared with conventional grafting technique regarding gained bone quality and quantity.
In conventional cleft grafting technique, there is always risk for grafted bone resorption and recurrence of fistula formation. So alveolar cleft grafting using anterior iliac crest bone particles combined with microplate fixation of maxillary segments will work more efficient and prevent the fore mentioned risk of graft resorption and recurrence of fistula.
In conventional cleft grafting techniques, most of the cases reported in literature raised a debate regarding the final gained amount of bone, with subsequent recurrence of oronasal fistula. In this study, alveolar cleft grafting using anterior iliac crest bone particles combined with microplate fixation of maxillary segments and the conventional grafting technique will be compared to evaluate which technique will offer better reconstruction of the alveolar ridge with maintained bone width and height.

| Label | Type | Description | Intervention Names |
|---|---|---|---|
| bilateral alveolar cleft grafting using iliac crest particulate and microplate fixation | Experimental | in bilateral alveolar cleft, the cancellous particulate bone graft from anterior iliac crest will be used to fill the defect, 8-hole microplates will be used to fix the premaxilla using screws. The microplates are to be removed 6 to 9 months postoperatively. |
