Secondary alveolar bone graft in patients with bilateral cleft lip and palate submitted to premaxilla repositioning: retrospective study

Introduction and Objective: This study aimed to analyze the effectiveness of the closure of oronasal communication, to report the importance of secondary alveolar bone graft repositioning of the premaxilla in patients with bilateral complete cleft lip and palate. Material and methods: This retrospective study analyzed the medical records obtained from the Cleft Lip and Palate Integral Care Center/ Association of Rehabilitation and Social Development of Cleft Lip and Palate Patients (CAIF/AFISSUR), Curitiba – Paraná – Brazil, to obtain statistical data involving 26 records of patients who underwent this surgery in the period between January/2010 – January/2014. Results and Conclusion: The benefits observed were: premaxilla stability, aided by the union of pre-maxillary segments; integrity of oronasal structure; aesthetic improvement; better bone support for the teeth adjacent to the cleft; support for the bridge of the nose reducing facial asymmetry and facilitating future rhinoplasty; orthodontic treatment without the limitation of the bone defect; closure of oronasal communication in 88% of patients
