Late alveolar bone grafting in complete unilateral cleft lip and palate (UCLP): Biomechanical considerations for the success of orthodontic finishing

Abstract

Orthodontic treatment in patients with cleft lip and palate (CLP) is challenging. Alignment of the maxillary segments and orthodontic levelling of the teeth adjacent to the cleft area are important before alveolar bone grafting (ABG), in the permanent dentition. In this clinical report, orthodontic procedures, before and after late ABG, are described as an alternative that can optimise the orthodontic and periodontal results. The gingival margins of the teeth adjacent to the cleft area were levelled. Root divergence was corrected. Interdental papilla and improvement of the periodontal condition were obtained.
