Role of bone graft materials for cleft lip and palate patients: A systematic review

AbstractCleft lip and palate is a congenital anomaly. Its management requires a long term commitment, multidisciplinary and structured treatment. Treatment is initiated at infancy and continues till adolescence. Bone grafting is performed in order to provide bony stabilization for cleft maxillary alveolar arch and room for subsequent canine tooth eruption. The aim of this review was to discuss the success of various bone graft materials in managing unilateral and bilateral cleft lip and palate patients. For this purpose, a detailed literature search was performed using available electronic databases for peer reviewed papers published in English language. The review is based on published papers reporting the use of various bone graft materials for managing cleft lip and palate patients. The success of bone grafts was studied using the grading scales measuring the bone height at the grafted sites. Various types of bone graft materials including autogenous and allogenic were reviewed. Implant placement in cleft lip and palate patients required bone grafting after orthodontic expansion because of deficient bone in the anterior maxillary region. The grafted bone consequently provides stability and support to the maxillary alveolar arch. Success of bone graft as well as dental implants is multifactorial and therefore depends upon the type of bone graft, bone quality at cleft site and severity of cleft lip and palate
