Surgical Treatment and Implant Restoration of Bilateral Incomplete Cleft Lip and Palate Patient with Constricted Maxilla and Congenital Missing of Upper Anterior Teeth: Case Report

Purpose: We report a case of a skeletal Class III patient with bilateral incomplete cleft lip and palate who successfully underwent orthodontic treatment with orthognathic surgery and dental implant restoration. Case Report: An 11-year-old girl with cleft lip and palate showed narrow maxilla and congenital missing of upper anterior teeth. To solve transverse deficiency of premaxilla and provide sufficient space for implant restoration, maxillary segmental osteotomy and transverse distraction osteogenensis with fan-type expander was operated. After growth, the patient took orthodontic treatment for orthognathic surgery. For implant restoration on the cleft site, tertiary alveolar bone graft with autogenous & alloplastic bone was performed. After revision surgery and filler injection on retruded upper lip, patient’s lateral facial profile was improved with balanced upper and lower lip profile. Conclusions: For successful implant restoration on alveolar cleft site, sufficient space needs to be regained and tertiary bone graft should be considered. Normal function and esthetic profile can be achieved by multidisciplinary treatment approach for the patient with cleft lip and palate.
