Background: Individuals with tooth agenesis often present a significant clinical challenge for dental practitioners. This retrospective study evaluated clinical and radiological long‐term functional and esthetic outcomes following restoration using primary teeth to support fixed all‐ceramic prosthesis in patients with teeth agenesis. Methods: Patients with teeth agenesis and at least one year follow‐up were included. Examinations included panoramic X‐ray, clinical examination and family history records. Only primary teeth without permanent teeth underneath were chosen. All ceramic fixed restorations were used. All data were collected from patient files. Outcome parameters included: restoration parameters (restoration survival, restoration fractures, restoration detach-ment, restoration replacement, and secondary caries), plaque index, and gingival index. Results: The study included 58 porcelain restorations inserted in 25 individuals; mean age 12 ± 2.1 years (range 10–19 years); mean number of missing teeth 12.3 ± 9 (range 6–12). Mean follow‐up 48±6 months (range 12–60 months). All restorations survived up to last follow‐up, rendering a survival rate of 100%. Restorations outcome – porcelain chipping (9%), detachment (2%), no restoration replacement nor secondary caries, mean gingival index ‐ 0.7 ± 0.5 and mean plaque index ‐ 0.9 ± 0.3. Conclusions: In tooth agenesis, restoration using primary teeth to support fixed all‐ceramic prosthesis is a viable treatment alternative.
