The Ankylos Dental Implant System was introduced into Korea in 1998 and has been used with good clinical results. This system was developed by professor G. H. Nentwig of Frankfurt University and professor W. Moser of Zurich University in 1985 and has been in clinical use with long-term data since 1987 in Germany. Reports showed a success rate of over 95.8% in Germany and 97.9% in Korea. Some of its significant design features include: (1) a progressive thread structure of the endosseous implant body for targeted load distribution to the apically positioned spongy bone; (2) the gap-free subgingival tapered connection to the abutments; (3) a narrow neck design which can maintain thick transmucosal gingiva around the abutment; and (4) all-in-one abutments which fit any fixtures with various length and diameter. Conventional submerged implantation or modified one-stage implantation and immediate loading with this system for many different types of prosthetic methods have been proved to be successful by the implant practitioners all over the world.
