  • Patent number: 10004576
    Abstract: A dental superstructure attaching system for use with a dental implant is provided. The system comprises a longitudinal member being connectable with an implant or an implant connecting member via an at least partially curved interface area. The longitudinal member comprises a main member forming the lingual part of said longitudinal member, and a lever member forming the buccal or labial part of said longitudinal member. The longitudinal member further comprises means for urging said lever member and said main member away from each other, such that said longitudinal member is secured to said implant or implant connecting member.
