1/2. Oral and maxillofacial surgical considerations for a case of Hutchinson-Gilford progeria.

    Hutchinson-Guilford progeria is a rare genetic condition showing the stigmata of accelerated ageing combined with severe growth retardation. patients with this condition show a classical facies and clinical features with an average age of death of 13, usually due to atherosclerotic changes. Craniofacial and dental manifestations include mandibular and maxillary hypoplasia, both vertically and horizontally. Delayed and abnormal tooth eruption and morphology are commonly present. The long-term medical prognosis and eruption potential of individual teeth is important when considering treatment. In addition to this, surgical planning and surgical technique must be modified by the abnormal facial morphology, dermal inelasticity, potential anaesthetic difficulties, and ongoing deterioration in the medical condition. These factors mandate early and definitive intervention for oral surgical conditions. We report the case of a 13-year-old male treated for pericoronitis and oral pain relating to delayed eruption of first permanent molars.

2/2. Functional and esthetic rehabilitation after mandibular resection in a child using a tooth/implant-supported distraction device: a case report.

    After resection and autogenous bone grafting in infancy and childhood, hypotrophy of the concerned jaw can often be observed. A 6-year-old male patient with osteogenic sarcoma was treated with partial resection of the mandible from the left first molar to the right first premolar. The aim was to rehabilitate the patient functionally and esthetically as he grew. At the age of 16, after the placement of 4 Branemark System implants in the consolidated autogeneous bone graft, the patient was treated with horizontal distraction osteogenesis. A new and unconventional type of individual tooth/implant-supported distraction device was used to lengthen the mandible by 16 mm. The implants placed to support the device were later used for prosthodontic rehabilitation. Progress in bone reconstruction, plastic coverage, and implant dentistry, as well as distraction osteogenesis, have enabled the compensation of functional and esthetic impairments caused by resection, especially in infants and young children.
