This report was aimed at presenting the clinical and radiographical findings of implant-supported single crowns maxillary rehabilitation after a 10-year follow-up. A 56-year-old woman, non-smoker, with no periodontitis history and no systemic diseases was unusually rehabilitated with 12 dental implants supporting single crowns replacing each tooth individually. Clinical assessment of plaque accumulation, quantity of keratinized mucosa, mucosal recession, probing depth, bleeding/suppuration on probing as well as radiographical marginal bone level evaluation were performed at baseline and after 10 years. Implant survival rate was 91.66% and no mechanical complications were observed. Marginal bone loss occurred mainly in the early stages of healing, and it was ≤3 mm after 10 years. Within the limitation of a single case, it could be concluded that implants with hexagonal connections supporting single crowns represented a good clinical option, enabling the patient to maintain a good oral hygiene, avoiding plaque accumulation and preserving an adequate althrough not ideal stability of tissue after a long-term clinical follow-up.
