It is hypothesized that survival rates after 1, 3, and 5 years of Straumann Roxolid® / SLActive® 4 mm short implants do not differ from values of Straumann SLActive implants with more than 4 mm length in the same clinical situation.
Main aim of this study was to assess survival rates of short implants with a length of 4 mm in the edentulous mandible after 1, 3, and 5 years.
