Background Single implant restorations have become the primary treatment option for young adults with missing anterior teeth. Yet, long‐term studies of single‐implants are limited in the literature. Purpose To report long‐term survival, success, and complications in young adults with single‐implants in the anterior maxilla. Materials and Methods A group of 42 patients (mean age 20.7 years) received 53 anterior maxillary single‐implants during 1996 and 1997. Data were collected at delivery of the crown, at 1‐year examination, and at 14‐20‐year examination. Descriptive statistics, estimated cumulative survival rates, Pearson correlation test, and t ‐test were performed. Results After 14‐20 years, 40 out of 42 patients were examined. Two patients were lost to follow‐up, two implants failed and ten original single‐crown restorations were replaced. Estimated cumulative survival rates were 96.1% for implants and 80.4% for implant‐supported crowns. Complications were seen in 21 patients. Mean probing depth was 4.0 ± 1.8 mm and mean marginal bone loss was 0.1 ± 1.1 mm. No correlation was found between marginal bone loss and probing depth, occlusal contact in maximal intercuspal position or usage of nicotine. Conclusions Long‐term prognosis of single implant treatments in the anterior maxilla in young adults must be regarded as good, with high survival and success rates.
