摘　　要：正常牙周组织和三种不同程度牙槽骨吸收者，采用圆锥型套筒冠义齿作牙周夹板，经有限元计算结果提示：咀嚼时，不同的牙周组织吸收，义齿支持组织应力会重新分布，牙周组织吸收越明显，牙周支持组织应力值越下降。Periodontal splints were made both on patients with peridontal absorption of three different degrees and on mormal situation respectively followed by finite element calculation.The result suggests that the stresses of the supporting tissues redistributed during mastication in accordance with different degrees of periodontal absorption.The more obvious of the pcriodontal absorption is the more stress value of the periodontal supporting tissues decrease,while those of the subbasal supporting itssues increase.
