A case of dental implant treatment for occlusal reconstruction in a congenital acute myeloid leukemia survivor

Patients: The patient was an 11-year-old boy with a medical history of congenital acute myeloid leukemia (AML). He received a series of treatments between 1 and 8 months of age, including chemotherapy, total body irradiation, and peripheral blood stem cell transplantation. Although the permanent incisors had erupted, both crown and root formation were incomplete. No tooth buds were observed for the remaining permanent teeth. The deciduous teeth were still present; however, their roots were shortened and showed mobility. At 18 years of age, growth of the upper and lower jaws had ceased; therefore, occlusal rehabilitation was performed using implants. All teeth except the first molars were extracted, and six implants were placed in the jaws. A screw-retained, implant-supported bridge was fitted, and regular follow-up and maintenance were scheduled. Four years and 9 months after placement of the final prosthesis, the occlusion has remained stable.
