    Golden opportunity for Align

     

    http://biz.yahoo.com/prnews/060202/sfth097.html?.v=27

    "In this Office Action, the examiner preliminarily rejected all 29 claims of the '893 patent. This non-final initial Office Action is considered routine in patent reexaminations, and now presents Align with its first opportunity to respond to the Patent Office's review and interpretation of the prior art with respect to these patent claims. Align is prepared to and will respond promptly to the Patent Office."

    The people that write ALGN's press releases have got to be chuckling while they write that stuff.

      This is getting rediculous. What does Align plan to do, issue a press release with each and every Office Action of the USPTO? So the claims were rejected ... big deal. They need to refrain from the details of patent prosecution and just deal with the IP when the patents issue/reissue or are revoked. Many persons are going to begin to lose faith in the legal dept when they do things like put out press releases on trivial matters and when they let the former CEO go without having him sign a non-compete agreement.

    • Can you explain to me why clearer is better? I've seen people wear aligners and I never noticed any lines. Perhaps OC aligners fit better because they're slightly larger and possibly not provide the torque needed to move teeth. That could explain the extra week needed between their aligners.

    • >Can you explain to me why clearer is better?<

      Clearer is better because people buy the product for it to be invisible/difficult to detect. OrthoClear is harder to detect, in part because of the initial clarity, and in part because it doesn't cloud during wear (Invisalign looks disgusting after two weeks, that is why they only do two week wear. OC does three week wear because they can accomplish that much without the aligners turning yellow). Clarity, both initial and eventual, matters to patients and therefore to doctors prescribing that to patients.

      Clarity is also a proxy for accuracy. OrthoClear's product is smooth and conforms to the tooth anatomy; Invisalign quite clearly does not track to the actual tooth anatomy, it has lines which must, by definition, reduce its accuracy. You are grabbing a tooth with an unsmooth surface, it obviously doesn't grab teeth as well, which is why all the orthos on this board keep saying it "fits better".

      >Perhaps OC aligners fit better because they're slightly larger< - actually, it is just the opposite, most people report that they are harder to remove than Invisalign.

      Red White and Blue and OrthoClear both have smooth surfaces.

    • Let me understand what you're saying. The only reason that Align presecribes their aligners are only worn for 2 weeks is because they turn yellow? It has nothing to do with the amount of change accomplished by the aligner? OrthoClear's do a better job because they're worn for 3 weeks? If they're made from the same plastic why doesn't OC's aligners turn yellow too?

    • Lets try to keep close to the truth here. The main reason OC uses a 3 week cycle is to work around Align's patents.

    • Let's, just for fun, say that your argument is correct. Clinical Studies have shown and clinical impressions confirm, that wearing aligners longer, leads to better results.
      Whatever the motivation, wearing longer, is better clinically. Even if patents motivate length of aligner wear, as you say, time will tell which is actually a better strategy.

      Where's Sam Kass? He's an expert on aligner wear patterns.

      since OC can only ship 2 aligners at a time, does the 6 week (vs 4 week) time period help give them time to order/receive the next set ? Is it a better or worse period between appointments to check movement ? better or worse balance of movement per aligner ? Any other factors ?

      Ultimately, from a patient perspective, what matters is 1) the results, 2) the cost, 3) the overall time from start to finish, 4) the comfort or pain level, 5) the number of office visists required (fewer is better if results are as good).

      Regarding clarity, as long as either is virtually unoticable for the 2 or 3 week wear period, then clearer doesn't matter.

    • >The only reason that Align presecribes their aligners are only worn for 2 weeks is because they turn yellow?<

      I never said that was the only reason. There are numerous other reasons, including the fact that it gets nicely around Align's patents. Please don't accues me of saying things I didn't say.

      > If they're made from the same plastic why doesn't OC's aligners turn yellow too?<

      Actually, it has nothing to do with the plastic. The yellowing is caused by the buildup of plaque and bacteria on the lines in the aligner. Picture it this way - let's say you have a staircase, and you threw plaque or some other sludge against it. A significant amount of sludge would get stuck in the steps, right? Second part of mental experiment - throw same sludge on smooth surface, let's say a wall that smoothly angles down at the same gradient as the steps would have. Less sludge. Less yellow.

    • Seems to be, but... the fact is that 3 weeks is the basic activation time (equivalent of a change in aligners) for braces and wires treatment. The other side of this coin is that 2 weeks may be perceived, by most of doctors, as insufficient. If what we are looking here is the truth, let`s remember it may show many angles. Hugs.

    • (Invisalign looks disgusting after two weeks, that is why they only do two week wear. OC does three week wear because they can accomplish that much without the aligners turning yellow).
      I didn't accuse you of saying something you didn't say. This is what you posted. I think you imply they turn yellow after two weeks and that's one of the reasons for only a two week wear period for each aligner.
      Additionally, ortho565 posted that perhaps one of the reasons that OC alingers fit better is because they are poured directly from an impression. Don't all gypsum products possess an expansion rate that would make the pour larger than a scan of the impression, thereby making the aligners fit better because of the slightly larger cast?
      I also like to ask about the plastic used for the manufacture of the aligners. Will any type work or are there some that work better than others?
