Introduction: Bone grafting of the alveolar cleft is necessary to facilitate unhindered growth of maxillofacial complex and eruption of permanent teeth in defect region when not congenitally missing. Secondary grafting undertaken during mixed dentition helps achieve these two functions. However, due to varying reasons, socioeconomic concerns being one of them, many patients do not undergo this procedure and report at a time when late grafting is the only option to overcome the deficit bone. Aims: To identify the different grafting materials that have been utilized for the 2 surgical procedures. Methodology: Electronic databases were searched to find bone sources used for secondary and tertiary bone grafting to identify their characteristics and clinical outcomes. Attention was paid to literature which elucidated potential use of dental implants in the grafted site and presented its clinical course. Results: Over the years, many graft materials have been researched upon with autologous sources being considered as the gold standard and being the most commonly utilized. Additionally, graft characteristics, observations of the published authors, and success of implant rehabilitation, where used showed a mixed bag of results. Certain other potential bone sources were also identified that have shown in-vitro or animal model success but have not yet made a clinical presence for the reviewed procedures. Conclusion: Choice of bone graft depends on numerous factors such as defect size, surgeon preference and patient acceptance. To understand further each graft source and its characteristics, randomized control trials should be conducted to provide better clinical evidence.
