(1) Background: The increasing utilization of three-dimensional (3D) photogrammetry has elevated craniofacial analysis to new dimensions. This scoping review seeks to provide a comprehensive overview of the current applications of 3D photogrammetry-supported craniofacial analysis within orthodontic practice, assess its technical superiority, and explore potential areas for enhancement. (2) Methods: A comprehensive search of the literature was carried across three electronic databases (PubMed, Web of Science, Embase). Two independent reviewers screened the articles and extracted data in accordance with the PRISMA-ScR guideline. The primary findings from the included articles were synthesized and analyzed qualitatively. (3) Results: A total of 479 records were obtained initially, with 53 articles ultimately included after removing duplicates and applying eligibility criteria. The application of 3D photogrammetry in craniofacial analysis has become prevalent in orthodontic practice, encompassing normative facial anthropometry, orthodontic problem finding, orthodontic treatment optimization, and treatment outcome evaluation. (4) Conclusion: 3D photogrammetry offers orthodontists a precise and efficient imaging technique for craniofacial analysis.
