Brief Summary:
A multicenter prospective observational study in which aim is to illustrate the clinical outcome of dental implants "Kontact N"; and the effects of its nanostructured surface on the osseointegration and secondary stability without increasing the rate of peri-implantitis. All the enrolled patients will be eligible for one or multiple implant-supported fixed restoration(s) according to the routine clinical practice and the manufacturer's instruction for use.

Official Title: Multicenter, Prospective, Observational Study on the Performance and Safety Use of the Dental Implant "KONTACT N" in the Current Clinical Practice
Actual Study Start Date : February 4, 2019

Actual Study Completion Date : January 13, 2022

Intervention Details:
  • Device: dental implant (KONTACT N)
    Implant-supported prosthetic restoration
    Other Names:

Primary Outcome Measures :
  1. Implant success rate [ Time Frame: up to 12 months post-implantation ]
    Rate of implants still in function up to 12 months post-implantation and which fulfill all the predefined success criteria in the protocol.

  2. Peri-implantitis rate [ Time Frame: 12 months post-implantation ]
    Peri-implantitis is an inflammatory process affecting the tissues around the implant and causing loss of bone support (diagnosed by radiographic and clinical assessment).

  3. Mean osseointegration period [ Time Frame: From the implantation up to 12 months ]
    Period from which a direct structural and functional junction can be observed between the remodeled living bone and the implant surface (by clinical and radiographic assessment).
