[Stess analysis of conical telescope denture using on the prosthodontic treatment for basic teeth combined periodontal diseases]
OBJECTIVE:Periodontal splints were made both on patients with peridontal absorption of three different degrees and on normal situation respectively followed by finite element calculation.The result sugree that the stesses 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 tissue decrease,while those of the subbasal supporting tissues increase.
