      Understanding Multiunit Abutment Tops

      Platform Dimensions

      DESS® multiunit abutment tops come in two sizes, regular platform (RP) and wide platform (WP).

      WP is only used in Nobel Brånemark® compatible parts. These abutments require a  Final DLC Multiunit (WP) Screw with their 5.0mmD.

       

       

      RP multiunit abutment tops have a 4.8mmD and use M1.4 screw threads. Systems with this platform type include:

      Compatible Parts

      Multiunit abutment tops can be found under On Top of Multiunit Components. These parts fit on top of the connections listed above, in addition to Keystone Dental® Group's Genesis and Prima lines.

      Because the Straumann® Screw-retained Abutment (SRA) has slightly different dimensions than the systems listed above, these can be found under On Top of SRA Components.

      Scan Bodies

      DESS® has two scan bodies available for multiunit RP abutment tops: Lab and Intraoral. Both scan bodies are reusable and autoclavable, while the intraoral scan body can be used in both the mouth and lab scanner.
