Abstract:
      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.
