三维有限元分析在牙周夹板研究中的应用

牙周炎是口腔常见病、多发病,是牙齿松动的主要原因之一.牙周夹板一直以来是松牙固定的有效手段,它可以将多个牙连成一个整体,形成一个“多根巨牙”,共同承担咬合力,有效地分散牙周膜及牙槽骨的应力,为牙周组织的愈合创造有利条件.三维有限元分析法是研究复杂模型应力分布的生物力学方法,近年来广泛应用于牙周夹板的研究中,该方法可以逼...

Application of three dimensional finite element analysis in the study of periodontal splint

Periodontitis is a common frequently-occurring oral disease,which is one of the main causes of loose teeth.Periodontal splint has always been an effective means of fixation of loose teeth.It can connect multiple teeth into a whole,form a"multiple giant teeth",bear the bite force together,effectively disperse the stress of periodontal ligament and alveolar bone,and create favorable conditions for the healing of periodontal tissue.Three-dimensional finite element analysis(FEM)is a biomechanical method to study the stress distribution of complex models.In recent years,it has been widely used in the study of periodontal splints.This method can realistically build a model of the oral tissue structure,assign values to the biomechanical properties of each tissue,and analyze the biomechanical characteristics under different geometric forms,different materials,and different loading conditions.It can provide biomechanical basis for the treatment of loose teeth.This paper reviews the application of 3 D finite element method in different types,materials and periodontal conditions of periodontal splints.
