Start up the Dental GPS software. Click on the File tab. a new project will automatically open. Click on the Facial Analysis tab, and again on the Facial Analysis. Click on Load picture. Note that the analysis is done from a single picture of the patient. Browse your system to load the desired picture.

With the next window, if your picture is too large (i.e. over 1024 x 768), the software will ask if you want to resize the picture (see Figure 1). This step is highly recommended if you plan to send the project by e-mail because a file that is too large might be rejected by your Internet provider.

By selecting Resize, the GPS automatically adapts the picture to the frame of the module. It also allows you to save the picture to the disk with a "_1024X768" suffix. Note that when using this option, the “precision” of your picture will be slightly reduced.

If you click on Do not resize, the picture remains at its full size and resolution. This application is ideal for providing your patients with a cosmetic consultations. You will then have the option to reduce or increase the picture yourself with the Dental GPS tools.

Note: It will be very important to ensure that the patient’s picture is very clear, of high quality, straight and well-centered. If the picture is not properly centered, the evaluation will be generally false. Therefore, the picture should be taken from directly in front with the patient’s head straight. Hair should be tied back to expose the whole face, ears and chin. A rotation of the picture will be possible afterwards. We will come back to this point a little later.

The GPS will then ask if you want to load this picture for a Smile Analysis (see Figure 2). Click Yes to load the picture into the three main modules:

• Facial Analysis
• Axial Inclination
• "M" Proportions

The modules will open automatically.
