3D Reconstructions Analysis of the Early Development of the Dentition

Abstract

3D Reconstructions has been widely used in the field of medical disease diagnosis and Marching Cube algorithm is the most representative structure in the face of 3D reconstructions. Therefore, methods of three-dimensional (3D) reconstructions were employed to visualize the surface morphology of developing structures and to help appreciate the complexity of early tooth morphogenesis. The authors introduce in the paper the principle of MCalgorithm, and present a simplified algorithm based on optimized grid model. The simplified algorithm selects points as close tooriginal grid as possible, usually using the subset selection method or the optimized selection method. The rudiments can rescue their suppressed development and revitalize, and then their subsequent autonomous development can give rise to oral pathologies. This shows that tooth-forming potential in mammals can be greater than that observed from their functional dentitions. From this perspective, the mouse rudimentary tooth primordia represent a natural model to test possibilities of tooth regeneration.
