Well there is a better way to deal with the challenges that the profession is imposing us, it is a good understanding of the techniques, profound analyze of the material properties and their impact on accuracy. A negative result can be an opportunity to find the missing segment of the puzzle that can sometimes change the whole picture. In other words do not leave an unsolved problem. Very often we blame the lab and sometimes there are reasons. How many of us took a day off and went to the lab to observe lab work in order to spot problems or to exclude the lab from the black list? Not many.
Once I've understood the mechanics behind the transfer impression (open and close tray) I realized that there is no chance in the world that transfer impression can be accurate. I can count three big reasons that can lead to misfit of the framework.
1. The impression is vulnerable when manipulated by the technician
2. The transfer impression is not reversible; the transfer does not return to its original position when moved during tray removal from the mouth (especially when there is a lack of parallelism between the implants)
3. The analog is mobile inside the model due to stone expansion
That's why I decided to quit the transfer technique and not use it ever.
Since I started using the direct impression my problems of framework misfit became a history. I turned my bad experience with the transfers to something positive, by spotting and understanding the reasons and switching to much better technique that assures peace of mind less complications and excellent results .
