Abstract
Objective:
The aim of this retrospective study was to evaluate the outcomes of secondary alveolar bone grafting and late secondary alveolar bone grafting in 66 unilateral cleft lip and palate patients.
Materials and Methods:
The total patients were 66 unilateral cleft lip and palate patients, out of which 19 patients underwent secondary alveolar bone grafting and 47 patients underwent late secondary alveolar bone grafting. Autogenous anterior iliac crest cancellous bone graft was harvested and used for grafting the alveolar clefts. Radiographic assessment based on Enemark’s scoring according to the marginal bone levels was done on the intraoral periapical radiographs taken 6 months after performing the surgery.
Results:
Twelve (63%) out of the 19 patients on whom secondary alveolar bone grafting was done achieved score 1 (optimal marginal bone levels), whereas only 12 (25%) out of the 47 patients achieved score 1 amongst the late secondary alveolar bone graftings. Overall results showed, probability, P = .034 (statistically significant).
Conclusion:
This study reaffirmed the fact that alveolar bone grafting when done in preadolescent age group (secondary alveolar bone grafting) gives better results in terms of marginal bony consolidation and maintaining the continuity of the alveolar arch, but the late presentation (late secondary alveolar bone grafting) should not be the refusal criteria for performing the alveolar bone grafting. Although the latter patients may not be rewarded in terms of bony consolidation as much as the preadolescent patients the potential of successful surgery in them still exists in terms of providing a platform for the dental implant placement, improvement in the soft tissue symmetry and aesthetics of the face.
