Marginal bone level alteration [ Time Frame: At 12 months after implant loading ] [ Designated as safety issue: No ]
Marginal bone level will be determined from radiographs and expressed as the distance from a reference point on the implant to the most coronal bone-to-implant contact on the mesial and distal aspect of the implant. Marginal bone level expressed in millimeters at the12 months follow-up visit will be compared to values obtained at delivery of permanent restoration i.e. loading (baseline).

  • Implant stability [ Time Frame: At implant loading (6-8 weeks after implant placement) ] [ Designated as safety issue: No ]
    Implant stability will be evaluated clinically/manually (recorded as stable yes/no)
  • Implant stability [ Time Frame: At 36 months after implant loading ] [ Designated as safety issue: No ]
    Implant stability will be evaluated clinically/manually (recorded as stable yes/no)
  • Implant survival [ Time Frame: At 36 months after implant loading ] [ Designated as safety issue: No ]
    Implant survival rate will be evaluated by clinically and radiographically count the number of implants remaining in function

Study on OsseoSpeed™ TX Narrow Implants in the Lower Jaw in a Chinese Population
An Open, Prospective, Multi-center Study to Evaluate OsseoSpeed™ TX Single Implant 3 mm Diameter in the Anterior Mandible. A 3-years Follow-up Study.

The purpose of this study is to investigate the clinical efficacy of Osseospeed™ TX 3mm diameter implant in a Chinese population by evaluation of marginal bone level alteration, implant stability and implant survival in the posterior mandible up to 3 years after loading. Hypothesis: Early loading of the 3 mm implant is a safe and predictable procedure.
