[QUOTE="CoolHandLuke, post: 302623, member: 4850"] I used it to qc models. Scanned models then did a GOM inspection to see deviaion and verify accuracy of technique. Woth IOS it isn't about the accuracy of the scanner that you have to go by. The accuracy of the scanner doesn't matter as much as your Technique because the technique if it is wrong will 100% of the time produce a model that is inaccurate no matter how accurate the scanners numbers may be. You can have a scanner accurate to under 10 microns but if your Technique is flawed then that scan will be deviant across the arch instead of at a local site. This means the technique is more important than the numbers of accuracy you can make any scanner work even something with 50 microns accuracy because the technique is such is that the scan does not deviate across the arch. For sure this model will not be accurate enough for a bar, but this scan will be useful and accurate for everything even crown and Bridge. Dedicated laser model scanners do not encounter this same phenomenon because their technique is always the same. A uses a laser and a sequence of rotation in order to create a model. There is no sequence of rotation to apply to an intraoral scan so technique becomes freehand and freehand I can prove to always produce a deviant model. [/QUOTE]
