RESUMEN
BACKGROUND: Initial rehabilitation in juvenile patients with oligodontia is a major challenge for the dentist. Conventional permanent prosthetic and/or implantological treatment options alongside permanent natural teeth are contraindicated in growing patients, because their skeletal development is still in progress. CASE REPORT: A non-invasive temporary-fixed treatment option for an adolescent patient is presented by the use of adhesively cemented (non-prep) all-ceramic onlays of primary teeth. The outcome of treatment was monitored over a period of 4 years. CONCLUSION: Long-term preservation of persistent primary teeth may be a meaningful alternative to removable dentures in growing patients with oligodontia. Intermediate rehabilitation should cause no more than mild psychological stress for the patient and improve quality of life, especially when extensive orthodontic and/or implantological treatment is planned at the end of the patient's skeletal growth.
