    Straight to multi unit zirconia

    The dentist is not above the law nor makes the laws when it comes to usage of any part that goes into the mouth. Any part that goes into the mouth for more than 30 minutes requires FDA, regardless of if from a dental lab or a dentist office. Jonathan and Rosen are doing the same thing - making...

    Straight to multi unit zirconia

    I would not use any screw as a final to zirconia direct to a MUA. Use a straight vertical wall tibase. These claims are completely unproven and unsubstantiated. This is why we go through stress and fatigue testing on parts such as tibases and for a "system" such as a screw going into zirconia...

    question regarding Ti custom abutment on Dentis implant

    In the USA if you are going to claim you are compatible with an implant system that you have to submit all the measurements, testing documents showing cross compatibility to the FDA and then the 510K will state this. This is why you will see implant company websites that no longer mention...

    Making abutments non-engaging

    Here is the testing done for stress and fatigue- 11mm tall by 5mm wide zirconia placed at 30 degree angled and pushed 5 million times at 300ncm - The perception and marketing hype is taller chimney = greater bond retention and stronger and the tooth will not break right around the top of the...

    Making abutments non-engaging

    the issue with ALL tapered wall tibases is a weaker bond retention. This is mechanical engineering 101. All you need is a 5 degree tapered wall and you decrease the bond retention by 68%. This is a test we did- following the same protocals for ISO 14801 stress and fatigue testing which is...

    Making abutments non-engaging

    I'm aware of DESS's parts, but they are extremely short. Are you referring to the collar height or the chimney.

    question regarding Ti custom abutment on Dentis implant

    Dentis is not 100% cross compatible with Hiossen regular. Their screw dimensions are different and the connection is slightly different.

    What Ti base is this?

    Zahn was selling glidewell's tibases. Zimmer has two different screws so whoever created this could have used either the zimmer urs2 screw which has a 2.30mm head diameter or Zimmer screw MHLAS which has a 1.95mm screw head. The corresponding screws from DESS are 19.012 for urs2 and 19.042 for...

    Angulated screw channel

    You can use the DESS straight tibases with different gingival heights and then use the angle screw channel screw. You will probably have to cut down the chimney possibly but this is another solution and all our tibases have vertical walls for maximum bond retention.

    Astra EV multibase abutments vs scanbodies

    The Astra EV multibase top is the same as Nobel MUA (and several others including biohorizons, neodent, 3i, etc). DESS has several solutions to help you that will enable you to scan on top of those MUA and then choose either tibase or direct to MUA solutions (for both temporary and final) ...

    email me so we can continue the discussions and I can check if the info is correct as well - [email protected] i noticed for example the BXL connection it states bone level is similar - it may be similar but it is not compatible with one another, the same with hiossen is not compatible with...

    Zimmer Multi-Unit Scan Bodies

    The Zimmer MUA has a proprietary top that is different than others. All of these MUA's have the same 4.8mmD top- Nobel, BioHorizons, 3i,Megagen, Hiossen, Neodent, BSB, Astra EV Multibase, and DESS Multiunits. Zimmer, MIS, Straumann, and Implant Direct have all proprietary tops.

    Straight to multi unit zirconia

    DESS USA has two libraries (for both exocad and 3shape) that enable you to got direct to the MUA without a tibase.....However we do not recommend doing this with zirconia. The libraries are on our website. One is using the DESS Multidirect library using the normal small screw that screws on top...
