Maxillary Anterior Teeth and Facial Index Parameters in Correlation With Recurring Esthetic Dental Proportion

Bellus3D is a modern multi-digital digicam, 3-D face scanning that captures in an expert grade, complete 3-D face scans with the pressing of an unmarried button in seconds. It takes 10 s to create an excessive decision 3-D face scan. Bellus3D's excessive precision scanning detects the soft tissue parameters and over a hundred facial andmarks. It uses two Infrared structured light VCSEL (vertical-cavity surface-emitting laser) projectors for high-resolution face scanning. The technique of facial scanning by (Bellus3D) and measuring facial index by (Medit) software was performed following manufacture instructions , The patient's head Stabilized and aligned with the center of the face scan software (Bellus 3D) to avoid scan distortion, The head was tilted towards right and then towards left along with the face analog in the scan software combined with upward and downward movement to ensure complete detection and record of facial landmarks. Then the obj 3D file exported to Medit Software.

Medit i-700 intra oral scanner was used to measure the teeth dimensions , it has several advantages including that it can capture up to 70 FPS (FRAMES PER SECOND), which is significantly faster than the previous model. It delivers high image resolution for better quality. The Medit i700 offers a remote control mode and a built-in UV-C disinfection function. In this study a zigzage movement was used which more accurate rout for recording all anterior teeth dimensions and surrounding tissue while scanning. In agreement with a previous study, we started from the posterior left area by scanning the occlusal side, then it proceeded toward the posterior right area by following a zigzag movement when the anterior teeth were scanned. After the occlusal area, the palatal/lingual side was scanned from the right to the left area, and then the buccal side was scanned from the posterior left area to the posterior right one,Then the obj 3D file exported to Medit Software.
