846 Bone Grafting as an Alternative Approach to Treating Severe Hypodontia in a Child

Abstract Background Severe hypodontia (developmental absence of teeth) can have significant functional and cosmetic impact, causing dietary restrictions, speech delay bullying. Management in childhood is usually with removable dental prostheses, but retention stability are often compromised by hypoplastic dento-alveolar bone ridges the edentulous areas. Presenting problems A 3-year-old child was referred to Paediatric Dentistry no erupted primary teeth. Radiographs revealed developmental entire dentition. Genetic investigation negative for changes genes known be associated hypodontia. In permanent dentition only first molars were radiographically present. The struggling bullying self-confidence related his appearance speech. Investigations Plain films cone beam computed tomography (CBCT) agenesis all canines incisors both jaws, an atrophic anterior maxilla, soft tissue communication nasal fossa floor. Clinical management Despite provision a retentive upper prosthesis made impossible fleshy maxillary ridge severe atrophy inadequate sulcus depth. Multiple prostheses fabricated, poor. He maxillofacial surgery excision redundant maxilla placement corticocancellous block graft from hip Sonic Weld (KLS Martin) augment consolidate ridge. successfully subsequently fabricated. Discussion This case presents unusually invasive, effective alternative approach treating childhood, where depth restrict treatment options.
