  Finite Element Analysis of Dental Implant Loading on Atrophic and Non-atrophic Cancellous and Cortical Mandibular Bone - a Feasibility Study, ELSEVIER SCI LTD
  článek v časopise ve Web of Science, Jimp
  The first aim of this study is to assess displacements and micro-strain induced on different grades of atrophic cortical and trabecular mandibular bone by axially loaded dental implants using finite element analysis (FEA). The second aim was to assess the micro-strain induced by different implant geometries and the levels of bone-to-implant contact (BIC) on the surrounding bone. Six mandibular bone segments demonstrating different grades of mandibular bone atrophy and various bone volume fractions (from 0.149 to 0.471) were imaged using a micro-CT device. The acquired bone STL models and implant (Brånemark, Straumann, and Ankylos) were merged into a three-dimensional finite elements structure. The mean displacement value for all implants was 3.1 um. Displacements were lower in the group with a strong BIC. The results indicated that the maximum strain values of cortical and cancellous bone increased with lower bone density. Strain distribution is the first and foremost dependent on the shape of bone and architecture of cancellous bone. The geometry of the implant, thread patterns, grade of bone atrophy and BIC all affect the displacement and micro-strain on the mandible bone. Preoperative finite element analysis could offer improved predictability in the long-term outlook of dental implant restorations.

  Finite element analysis of bone loss around failing implants, ELSEVIER SCI LTD
  článek v časopise ve Web of Science, Jimp
  Dental implants induce diverse forces on their surrounding bone. However, when excessive unphysiological forces are applied, resorption of the neighbouring bone may occur. The aim of this study was to assess possible causes of bone loss around failing dental implants using finite element analysis. A further aim was to assess the implications of progressive bone loss on the strains induced by dental implants. Between 2003 and 2009 a total of 3700 implant operations were performed in a private clinic. Ten patients had 16 fixtures which developed severe marginal bone defects. Finite element analysis was used to assess the effective strains produced at the bone-implant interface under unidirectional axial loading. These simulations were carried out on 4 specific implant types – Camlog Plus, Astra Osseo Speed, Straumann BL and Straumann S/SP. All implant types displayed degraded performance under circular and horizontal bone loss conditions. This is evidenced by increased distribution of pathological strain intensities (>3000 micro-strain), in accordance with the mechanostat hypothesis, in the surrounding bone. Among the implants, the Camlog design seemed to have performed poorly, especially at the chamfer in the implant collar (>25000 micro-strain).Implants are designed to perform under nearly ideal conditions from insertion till osseointegration. However, when the surrounding bone undergoes remodelling, implant geometries can have varied performance, which in some cases can exacerbate bone loss. The results of this study indicate the importance of evaluating implant geometries under clinically observed conditions of progressive bone loss.

  Proces zhotovení fyzické modelu lebky vyžaduje řadu kroků, z nichž každý je potenciálním zdrojem geometrické chyby. Cílem této studie bylo prokázat nepřesnosti a rozdíly způsobené DICOM do STL a obrácení aditivně vyrobených modelů lebek.
