查询词典 periodontal

The solid modeling based on STL dare mesh instead of the one based on surface is created to increase morphological comparability. Topological relationship among polygons is reconstructed to modify and Boolean operation. Periodontal ligament, supporting bone and glass fibers are reasonably predigested and constructed in CAD system to reduce the amount of mesh. FEA meshes are generated through splitting method to improve quality of mesh.

Short horizontal brush method (also known as the level of vibration method): People used to cross-brush method is a long see-saw action, such cross-hair brush method, if coupled with a hard toothbrush would be damaging to the periodontal (gum brush the edge of injury , gingival recession, root neck, wedge-shaped defects, etc.).

短横刷法：用于交叉以人刷法是一项长期拉锯式的行动，例如跨毛刷方法，如果用硬牙刷加上将有损于牙周（牙龈刷受伤的边缘，牙龈退缩，根颈部楔状缺损等）。
