Effects of Crown Material Type on Stress and Strain Distributions in Peri Single Implant Bone: A Pilot Finite Element Study
Purpose : To investigate stress distribution pattern, maximum von Mises stress and volume average values of von Mises stress and strain around peri-implant bone on a single crown implant with different crown materials under various loading locations.
Material and method : Two different occlusal loading locations (central fossa and 2-mm offset horizontally) and five different material properties (ceramic, gold alloy, hybrid ceramic, resin acrylic and polyetheretherketone) of a single crown were taken into account to explore stress and strain transferred from the crown to the surrounding bone through the implant. Bone-implant models were constructed and loaded under an axial compressive force of 200 N. Abaqus program was used to analyze stress distribution pattern, maximum von Mises stress, and strain in the peri-implant bone using finite element method.
Results : Similar stress distribution pattern was presented in all groups, which greater stress and strain were concentrated around cortical bone at the neck of the implant. Different loading locations affected stress distribution pattern. The 2-mm offset loading presented higher stress concentration at the neck of the implant and greater von Mises stress and strain values around peri-implant bone than the central fossa loading. No differences of von Mises stress and strain values around peri-implant bone were found when loaded the crown with different material properties.
Conclusion : Within the limitation of this study, loading location influenced the stress distribution pattern around the peri-implant bone of the single crown implant. Off-axis loading tends to increase stress and strain values compared to the central fossa loading. Crown materials were not affected the stress and strain values around the peri-implant bone.
