Retention Types
Screw-Retained
Screw-retained implants are easier to retrieve than cement-retained, however cannot be used on cases with draw issues or screw access hole issues.
Cement-Retained
Cement-retained restorations will work on any case, and have improved aesthetics due to the lack of an access hole. However, cement-retained restorations are more difficult to retrieve and they use cement, which comes with a higher chance of periodontitis.
Screwmentable
Combines the easy retrievability of screw-retained with benefit of universal path of draw like a cementable restoration. Screwmentable cases work no matter the path of draw, but are limited when there is a screw access hole issue or if cement cannot be used.
