Here is another case done with Archform, the $50 per case, in office aligner software. If you saw my last case, I really only recommend this software for those familiar with Ortho and aligner therapy. Scanned in CEREC Ortho and exported as an STL. Class I Molar and Canine, just a little crowded.
Typical Ortho relapse case. Had First PreMolars extracted as a kid. The MB Cusp of the uppers lines up with the buccal groove of the lower molar and the canine lines up with the inter proximal of the upper canine and lateral (Class I molar and canine). The canines are tipped buccally on the uppers, so we want to tip those in. We have #5 rotated and #8 could stand to be extruded. Lower incisors are a bit crowded.
Horizontal attachments are good for extrusion. Ellipsoid are good for crown rotation and if you pair them, for root torque. I didn’t do it on the last Archform Case, but I am putting ellipsoid attachments on all first molars just to seat the guide and provide some anchorage.
Although I am a huge Form 2 and Moonray fan, there are a few out there that don’t want to spend the big bucks or are maybe, a little unsure if 3D printing is right for their practice. The Anycubic Photon is $529 bucks and its a nice little printer. It does require a bit of computer suaveness as it does not hook up wirelessly (you need to process the model in a software, enter the parameters per each resin). But it does have a nice color touch screen. I used FTD resin which is $65 a liter, the US distributer has stopped selling it for now, so you may need to order from Canada at $75 a liter plus shipping. Pressure formed with a Drufomat.
Everything else is status quo. We had about .2mm of IPR around the lower incisors and just between 8 and 9 which was bonding anyway. We have about 10 sets of aligners, so will post the finals!
