Case Report: Multiple Tooth Agenesis-A Re-Update after 11 Years

Case report: A 10-year-old patient was referred by her orthodontist with agenesis of teeth 14, 13, 12, 22, 23, 24, 25, and 45 (N=8). Initial treatment started with transplantation of primary teeth 73  22, 83  12 and the premolar 35  24 to create a balanced number of premolars in all four quadrants. The primary tooth transplant was performed with the technique as described previously [1-3]. The dental arches in the upper and lower jaws were reformed and developed by the orthodontist. Eleven years later, the patient presented again aged 21 to replace the primary tooth transplants with endosseous implants. Result: The transplanted primary teeth in position12 and 22 were in place for 11 years and helped to ensure good co-development of soft and bone tissue. The definite care of the patient with implants in positions 12 and 22 was performed without the need for extensive bone-augmenting measures. The premolar transplant in position 24 remained undisturbed in place. The bite-raising by the orthodontist in the meantime achieved an aesthetically pleasing result. Conclusion: The combination of autogenous tooth transplants in childhood and endosseous implants in late adolescence yields reliable aesthetic and functional rehabilitation of patients with agenesis of multiple teeth. Early detection of these patients is crucial for this treatment option.
