Reliability and the smallest detectable differences of lateral cephalometric measurementsJanalt Damstra
Department of Orthodontics, University Medical Center Groningen, University of Groningen, Groningen, The Netherlands
Am J Orthod Dentofacial Orthop 138:546.e1-8; discussion 546-7. 2010..The aim of this study was to determine the reliability and the measuring error (by means of the smallest detectable error) of 11 angular and 4 linear measurements commonly used for cephalometric analysis...- Simple technique to achieve a natural position of the head for cone beam computed tomographyJanalt Damstra
Department of Orthodontics, University Medical Centre Groningen, University of Groningen, The Netherlands
Br J Oral Maxillofac Surg 48:236-8. 2010..We developed a modified laser level technique to record the natural position of the head in all three planes of space. This is a simple method for use with three-dimensional images and may be valuable in routine craniofacial assessment... - Accuracy of linear measurements from cone-beam computed tomography-derived surface models of different voxel sizesJanalt Damstra
Department of Orthodontics, University Medical Center Groningen, University of Groningen, PO Box 30 001, Groningen, 9700 RB, The Netherlands
Am J Orthod Dentofacial Orthop 137:16.e1-6; discussion 16-7. 2010.... - Comparison between two-dimensional and midsagittal three-dimensional cephalometric measurements of dry human skullsJanalt Damstra
Department of Orthodontics, University Medical Center Groningen, University of Groningen, The Netherlands
Br J Oral Maxillofac Surg 49:392-5. 2011..88) and that there were no significant differences (P=0.41-1.00). The values from the cephalometric analyses were comparable and interchangeable when using the midsagittal three-dimensional approach as described... - A three-dimensional comparison of a morphometric and conventional cephalometric midsagittal planes for craniofacial asymmetryJanalt Damstra
Department of Orthodontics, University Medical Center Groningen, University of Groningen, PO Box 30 001, Groningen, 9700 RB, The Netherlands
Clin Oral Investig 16:285-94. 2012..Care has to be taken using cephalometric midsagittal planes for diagnosis and treatment planning of craniofacial asymmetry as they might differ from the true plane of symmetry as determined by morphometrics... - Evaluation of anthropometric accuracy and reliability using different three-dimensional scanning systemsZacharias Fourie
University Medical Center Groningen, University of Groningen, Department of Orthodontics, Hanzeplein 1, 9700 RB Groningen, The Netherlands
Forensic Sci Int 207:127-34. 2011..Measurements recorded by the three 3D systems appeared to be both sufficiently accurate and reliable enough for research and clinical use... - Reliability and the smallest detectable difference of measurements on 3-dimensional cone-beam computed tomography imagesJanalt Damstra
Department of Orthodontics, University Medical Center Groningen, University of Groningen, Groningen, The Netherlands
Am J Orthod Dentofacial Orthop 140:e107-14. 2011..The aim of this study was to determine the reliability and the measurement error (by means of the smallest detectable error) of 17 commonly used cephalometric measurements made on 3-dimensional (3D) cone-beam computed tomography images... - Accuracy and reliability of facial soft tissue depth measurements using cone beam computer tomographyZacharias Fourie
University Medical Center Groningen, University of Groningen, Department of Orthodontics, Hanzeplein 1, 9700 RB Groningen, The Netherlands
Forensic Sci Int 199:9-14. 2010..For more accurate data collection the 0.3mm voxel size should be considered... - Segmentation process significantly influences the accuracy of 3D surface models derived from cone beam computed tomographyZacharias Fourie
University Medical Center Groningen, University of Groningen, Department of Orthodontics, Hanzeplein 1, 9700 RB Groningen, The Netherlands
Eur J Radiol 81:e524-30. 2012..To assess the accuracy of surface models derived from 3D cone beam computed tomography (CBCT) with two different segmentation protocols... - Antero-posterior and transverse changes in the positions of palatal rugae after rapid maxillary expansionJanalt Damstra
Department of Orthodontics, University Medical Centre Groningen, The Netherlands
Eur J Orthod 31:327-32. 2009..The medial aspects of the third rugae cannot be considered as stable reference landmarks for dental cast analysis when RME is performed in addition to fixed appliance therapy... - Combined 3-dimensional and mirror-image analysis for the diagnosis of asymmetryJanalt Damstra
Postgraduate Student, Department of Orthodontics, University Medical Center Groningen, University of Groningen, Groningen, The Netherlands
Am J Orthod Dentofacial Orthop 140:886-94. 2011..Other advantages of a mirror-image analysis, in addition to the quantitative analysis, are also discussed... - Practical limitations of cone-beam computed tomography in 3D cephalometryJanalt Damstra
