Background: The necessity of a minimum volume of keratinized tissue around implants to maintain tissue stability remains a matter of debate. The aim of this case series is to showcase the outcome and long-term maintenance of dental implants that received soft tissue augmentation. Case Presentation: Three cases of second stage following dental implant placement were evaluated for amount of keratinized tissue. Based on the Ono-Nevins classification described here, treatment was rendered including keratinized tissue grafting. The cases were followed for 10, 18 and 28 years. Each case demonstrated maintenance of soft and hard tissue profile around the dental implants with no incidence of peri-implantitis as evidenced on clinical examination and use of peri-apical radiographs. Conclusion: Soft tissue management around dental implants may play a key role in long-term maintenance of peri-implant health and prevention of peri-implantitis.
