Accuracy of Two Different Photogrammetric Software for Three Dimensional Facial Model Reconstructions Compared with Direct Facial Anthropometry.
This study will be carried out on fifty volunteers, selected from outpatient clinic at Department of Orthodontics, Faculty of Dental Medicine, Al-Azhar University, Assiut branch; aged 18 years or older.

Exclusion Criteria:
Presence of:
Accuracy of Photogrammetry in Generating 3D Facial Models - Linear Measurements
* A 3D model was generated for each volunteer using photogrammetry software. Anthropometric linear measurements was taken using a digital caliper, and photogrammetric linear measurements was extracted from the 3D model. * Two LEGO® blocks with uniform dimensions were attached to the participants' faces to scale the 3D model to actual metric dimensions. Unit of Measure: millimeters(mm)
Time frame: Baseline (procedure)
Accuracy of Photogrammetry in Generating 3D Facial Models - Angular Measurements
* This outcome measure focuses on the accuracy of photogrammetry in capturing and reproducing angular measurements of facial features. * Volunteers' 3D facial models were generated using photogrammetry software from multiple photos. * Two LEGO® blocks with uniform dimensions were attached to the forehead and cheek for scaling and reference. Angular measurements, based on these blocks, were extracted from the 3D model. The measurements were compared to validate the method's precision in reproducing angular dimensions. Unit of Measure: Degrees (°)
Time frame: Baseline (procedure)
Ran from Sep 2024 to primary completion in Nov 2024, 2 months.
Of 32 observational studies under Malocclusion, half reached primary completion within 25 months of starting (the median), counting those still running; a quarter within 12 and three quarters within 46. This study's 2 months is below that.
