Purpose
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.

Further study details as provided by Dentsply Implants:
Primary Outcome Measures:
- 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).
Secondary Outcome Measures:
- 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
