摘要：This study aims to predict the density distribution in human jawbone
   surrounding a dental implant. Based on the two popular, yet distinctive
   theories for bone remodeling,a new remodeling algorithm is proposed
   which takes into account both the 'lazy zone' effect and the
   self-organizational control process. To demonstrate the ability of the
   proposed algorithm in predicting the density distribution of bone
   surrounding a dental implant,a 2D finite element model of implant and
   jawbone is studied. The effects of two parameters, viz the reference
   value of strain energy density(SED) and 'lazy zone' region,on the
   density distribution are also investigated. The proposed algorithm is
   proven to be effective and the predicted results correlates well with
   clinical observations. This study has demonstrated that consideration of
   the lazy zone is less important than consideration of the SED induced
   within the bone
