title: [Establishing three-dimensional reconstruction and measuring system for complete denture occlusion].
abstract: OBJECTIVE
  This study was designed to investigate the digital method of locating and reconstructing the occlusal relationship between the upper and lower full dentures.
  
  
  METHODS
  The artificial teeth occlusal surfaces of ten complete dentures were scanned by non-contact laser scanner and were reconstructed by three-dimensional technique. With placements of 6 standard steel ball, the three-dimensional position relationship of upper and lower full dentures were studied and reconstructed in centric occlusal position.
  
  
  RESULTS
  The three-dimensional reconstruction and measuring system of complete denture occlusion was preliminarily established in this study.
  
  
  CONCLUSIONS
  This study focused on exploiting a new system to quantitatively reconstruct the occlusal relationship of complete denture in centric occlusion. And the study may set a methodological foundation of further three-dimensional research for complete denture occlusion.
