A clinical technique for virtual articulator mounting with natural head position by using calibrated stereophotogrammetry. WYH Lam, RTC Hsung, WWS Choi, et al.

Date: September 2017. Source: The Journal of Prosthetic Dentistry (Online). Abstract: Accurate articulator-mounted casts are essential for occlusion analysis and for fabrication of dental prostheses. Although the axis orbital plane has been commonly used as the reference horizontal plane, some clinicians prefer to register the horizontal plane with a spirit level when the patient is […]

Evaluation of Head Position in Static and Dynamic Three-Dimensional Imaging: a review of the Literature. M Kjærgaard Larsen, TH Thygesen.

Date: August 2017. Source: International Journal of Oral and Craniofacial Science, 3(2), pp 34-38. Background: : The interest in three-dimensional imaging in orthognathic treatment planning has been growing, especially for evaluation of the natural head position. Several three-dimensional devices are available on the market. Three-dimensional evaluation of the patient will probably soon be a standard […]

Recording of Natural Head Position Using Stereophotogrammetry: A New Technique and Reliability Study. TC Hsung, J Lo, TS Li, LK Cheung.

Date: November 2014 Source: Journal of Oral and Maxillofacial Surgery, 72(11): 2256-61. Abstract: The purpose of this study was to develop a technique to record physical references and orient digital mesh models to a natural head position using stereophotogrammetry (SP). The first step was to record the digital mesh model of a hanging reference board […]

Three-dimensional reproducibility of natural head position. DW Weber, DW Fallis, MD Packerc.

Date: May 2013 Source: American Journal of Orthodontics and Dentofacial Orthopedics, Volume 143, Issue 5, pp 738-744. Introduction: Although natural head position has proven to be reliable in the sagittal plane, with an increasing interest in 3-dimensional craniofacial analysis, a determination of its reproducibility in the coronal and axial planes is essential. This study was […]
