Clinical Trial Summary

Intermediate grafting with both pre- and post- grafting maxillary expansion with time span after grafting 6-8 weeks for consolidation and final retention for 3 months after finalization of expansion will get the advantages of both techniques combined.


Description:

Secondary alveolar bone grafting (SABG) is an essential step in the overall management of Patients with cleft lip and palate (CLP). The numerous advantages of this procedure have been reported in the literature. However, resorption of the bone graft is a common situation, and the success of alveolar bone grafting (ABG) depends on several factors . The periodontal health of the surrounding graft tissues, the experience and ability of the surgeon and the timing of surgery are shown to be the most important factors determining success. Failure to rehabilitate the alveolar cleft may give rise to a variety of problems, including oronasal fistula, fluid reflux, speech pathology, impaired tooth eruption, lack of bone support for the anterior teeth, dental crowding, periodontal recession and eventual loss of teeth, and maxillary and facial asymmetry . Lack of alveolar bone also limits orthodontic treatment and/or prosthodontics rehabilitation. Post graft stimulation of maturation through remodeling of the graft is extremely important and is provided primarily by natural tooth eruption. Thus, the ideal time period for SABG is shown as to be the mixed dentition stage (9-12 years), just before the eruption of the permanent canine in line with the cleft. Timing of maxillary expansion in patients with cleft lip and palate is debated. Proponents of expanding the maxilla prior to secondary alveolar bone grafting state it is beneficial to align the segments prior to bone grafting better access for placement of the graft and working facility during surgery, However more recent literature shows maxillary expansion after secondary bone grafting is possible Advocates of expansion following grafting cite the advantages that bone consolidation is improved when the graft is placed under a dynamic load during healing and that there is a smaller soft tissue defect to close, less difficulty procuring an adequate volume of bone, and a narrower defect, which will regenerate bone more quickly and less possibility to induce oronasal fistula during maxillary expansion the study will change the concept of alveolar bone grafting in relation to maxillary expansion .just getting 5 mm minimal between two cleft edges and 2/3 of canine or lateral root has been formed and thin bone separate tooth from cleft defect the graft could be done
