Editor's Notes
- Here, we have the Straumann implant line up. (Click on implant type to expand for info. on implant line.)
- Standard implants have a 2.8 mm smooth collar height, whereas Standard Plus and Tapered Effect implants both have 1.8 mm smooth collar heights.
- These are the different dimensions on this slide: Top dimension: restorative platform/neck diameter Bottom dimension: endosseous diameter in the bone Noted at the bottom is the abbreviated name of each implant: Standard, endosseous diameter, neck diameter (example: S, Ø 4.1 mm, RN) S = Standard implant RN = Regular Neck ( Ø 4.8 mm restorative platform) WN = Wide Neck ( Ø 6.5 mm restorative platform)

- Straumann’s Morse taper implant-to-abutment connection is the only internal connection that is backed by long-term data supporting the near elimination of abutment loosening. (Read the slide.) Loosening torque slightly higher than tightening torque means that you need slightly more force to remove the abutment than when you torqued it in All abutments are torqued to 35 Ncm As we will see on a later slide, 91% of the functional load is transferred into the Morse taper instead of onto the abutment screw, which helps protect it from the risk of fracture On the next slide, you will get a better understanding of the stability against rotational loosening
- Straumann implants have an internal 8 degree taper, which allows for a mechanically locking friction fit with Straumann abutments. Historically, the problems with screw loosening were associated with the hex-top concept. Straumann offers an internal implant-to-abutment connection that has defined today’s industry standards. The Morse taper is a well-established engineering principle that originated in aeronautics and was used to anchor heavy objects together. This principle, where 8 ° or less yields a mechanically locking friction fit, has proven to be superior to traditional external connections as well as other forms of internal connections where you are still only relying on a screw-through-abutment as the anchorage mechanism. In these cases, the same potential for screw loosening exists.
- And here you see a cross-section of the implant with a solid abutment. With the Morse taper connection, 91% of the functional load is transferred into the Morse taper and only 9% of the functional load is put on the screw thread. This helps minimize the risk of abutment fracture.
- Nearly all abutments are compatible with all implants. Here we see the Regular Neck implants and abutments. Although the implants have different endosseous shapes and sizes, they all have the same Ø 4.8 mm restorative platform – therefore making them compatible with all the various Regular Neck abutments.
- Solid abutments and impression components for cement-retained restorations are color-coded according to their height. The yellow solid abutment is 4.0 mm in height and is for Regular Neck implants The grey solid abutment is 5.5 mm in height and is for Regular Neck implants The blue solid abutment is 7.0 mm in height and is for Regular Neck implants The green solid abutment is 4.0 mm in height and is for Wide Neck implants The brown solid abutment is 5.5 mm in height and is for Wide Neck implants
- The synOcta ® system offers additional restorative options. Because of the implant level impression capability of the synOcta ® system, the position of the implant can be precisely transferred to the model allowing abutment selection to take place outside of the mouth, making it possible to plan and finalize the case on the model. The synOcta ® system can be especially useful for esthetically demanding cases, multiple unit cases or cases with angulation issues. The synOcta ® system allows for a laboratory produced provisional that is screwed directly into the implant for soft tissue contouring. As you can see, there is an octagon which has been milled into the internal aspect of the Morse taper inside the implant. This internal octagon provides added restorative versatility by allowing for implant level impressions (which can be done at the time of surgery if necessary) and transferring the implant position to the models.
- This is the synOcta ® abutment range. There is a synOcta ® abutment available for every clinical indication for both the Regular Neck implants and the Wide Neck implants.
- The NN (Narrow Neck) implant is part of the Standard Plus implant line because it has a 1.8 mm smooth collar height. It is a “one-part” implant because it has a built-in octa abutment. The restorative platform is 3.5 mm in diameter. Various abutment copings are available for either cement or screw-retained single crowns (to replace upper lateral incisors, and lower central and lateral incisors).
