Just create a new account and in the dashboard you will find a download section with the current version of Bite-Finder. Just download it and install it. You will be guided by the setup wizzard and it is quite easy.
After installing and opening Bite-Finder for the first time you will be asked for a license key. Please go to your dashboard and copy your license key and paste it into the application.
Then you can start using Bite-Finder.
Load 2 models, run Bite-Finder, save and proceed with your CAD.
Please check the result. In rare cases it is not possible to compute a correct occlusion (i.e. missing all molars, not enough stability, anything that need manual fixation in real life) or there are two plausible situations. You can calculate the same models multiple times for free. Maybe it helps rearranging the models close to the situation by selecting and moving one jaw.
You will get a folder with 2 transformed models (stl/obj/ply) in correct position, a JAWMOTION file (XML) to use for the individual dynamic occlusion in your CAD and not use an average articulator and a video that documents the whole process for storage or communication between lab, dentist and patient.
