Based on the premise of Leonardo da Vinci who determined that the ideal facial balance occurs when the face can be divided in to 3 equal vertical dimensions. This app was created by Dr. Peter Boulden, an Atlanta Cosmetic Dentist to help with his cosmetic dentistry procedures. Utilizing the iPad camera, evalution is done simply and easily by dragging two primary lines (the app shows you how). The lower third of the face is supported by the teeth, yet if those teeth become too worn down it can cause the lower third to collapse and distort the harmony of the face. Additionally, it was helpful in determining VDO (vertical dimension of occlusion) for cosmetic denture patients. This app is not intended to be diagnositc or clinical in nature, but as an educational / evaluation tool.
