To investigate the clinical efficacy of Osseospeed™ TX implants 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 posterior mandible is a safe and predictable procedure.
Partially Edentulous Jaw
Device: OsseoSpeed TX
||Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment
||An Open, Prospective, Multi-center Study to Evaluate the OsseoSpeed™ TX Implant With an Early Loading Protocol in Patients With Tooth Loss in the Posterior Mandible. A 3-years Follow-up Study.
Primary Outcome Measures:
Secondary Outcome Measures:
- Implant stability [ Time Frame: At implant placement, loading and at 6, 12, 24 and 36 months follow-up. ] [ Designated as safety issue: No ]
Implant stability will be evaluated clinically/manually (recorded as stable yes/no)
- Soft tissue status [ Time Frame: At loading and at 6, 12, 24 and 36 months follow-up. ] [ Designated as safety issue: No ]
Soft tissue status will be measured by assessment of bleeding on probing and measurement of probing pocket depth.
- Plaque [ Time Frame: At 6, 12, 24 and 36 months follow-up. ] [ Designated as safety issue: No ]
Occurrence of plaque around the study implant will be recorded.
- Implant survival [ Time Frame: From implant placement to 36 months after loading. ] [ Designated as safety issue: No ]
Implant survival rate will be evaluated clinically and radiographically.

- Previous enrolment in the present study.
- Simultaneous participation in another clinical study or participation in a clinical study during the last 6 months.
- Subjects that are unable to give informed consent
