Nevertheless, the evidence for 5\u2010year survival rates remains inconclusive or insufficient for the remaining combinations of implant lengths and clinical scenarios. They include 4\u2010mm and 5\u2010mm implants as alternatives to sinus lift as well as placing all implant lengths \u22646\u2009mm instead of vertical ridge augmentation with long implants.
