If the TMJ opens in Preview, the text will appear garbled and the images won't load:

Because of the 3D elements embedded into the pdf file that is the TMJ, it will only display in Adobe Acrobat Reader. To force the TMJ to open in Reader, first navigate to Applications/TMJ_Occlusion_Atlas. Right-click on TMJ_Atlas.pdf, choose, "Open With," then "Other" and then set TMJ_Atlas.pdf to always open with Adobe Reader.
