[The impact of occlusal plane orientation method on intercuspal occlusion estimation]

The study was conducted on 50 students with orthognatic bite aged from 17 to 23 years. After taking impressions of the upper and lower dental arches and making cast models these were fixed in articulator Inter-frame space in four ways: by means of facial arch oriented on Camper plane or Frankfurt horizontal, with the help of standard semianatomical table or HIP-analyzer and a table for fixing the HIP-plane. Occlusal contacts were checked with occlusion paper (200 microns, Bausch) in the central, lateral and anterior occlusion and then analyzed using Adobe Photoshop and Universal Desktop Ruler. The most precise results were seen in cases casted by means of HIP-analyzer.
