Abstract:
PURPOSE: This study was designed to investigate an algorithm model, which can simulate the protrusive movement for complete denture on articulator. METHODS: A typical edentulous case with one-year complete denture was selected for this study. A new complete denture remounted on articulator Hanau H2 was scanned and reconstructed by three-dimensional technique. With the geometrical parameters of the articulator, a series of mathematical equations describing the three-dimensional protrusive movement of complete denture on articulator were solved by programming in Matlab6.5 (a language for technical computing). RESULTS: The algorithm model to simulate the protrusive movement of complete denture on articulator was established and was testified by the true case in this study. CONCLUSIONS: This study verified the use of a new method to quantitatively study the protrusive movement simulation of complete denture in terms of spatial coordinates. And the quantitative simulation may play an important role in further research of the dynamic occlusion to improve dental restorative procedures.
Keywords:Complete denture   Algorithm model   Protrusive movement   Articulator   Three-dimensional simulation
