Bio-Adaptable Dental Implants


DESCRIPTION:

The current project deals with the design and production of Bio-adaptable dental implants. The classical dental implant is a screw-like assembly of three titanium alloy components; the rootform, the abutment, and the assembly screw. This implant is anchored to the predrilled jaw-bone which prevents micromotion. In addition, the elasticity mismatch between the jawbone and the titanium alloy causes stress shielding which leads to bone atrophy and implant loosening. Bio-adaptable dental implants which mimics the shape of natural teeth employs Functionally Graded Porosity (FGP) in order to optimize the local mechanical behavior of the material at the root which minimizes the stress shielding, producing healthier and faster Osseointegration which leads to longer implant life and faster healing time. In addition by employing FGP at the abutment area, a micromotion of the dental prosthesis relative to the root is obtained, which contributes to a more natural bite feel, as well as proposes some new clinical applications. Digital engineering is extensively used in order to capture the shape and biomechanics found in the natural dentition, to render that shape and biomechanics into a optimized Bio-adaptable dental implant, and to produce the actual Ti-6Al-4V implant (EBM). For more information please go to http://www.intechopen.com/books/implant-dentistry-a-rapidly-evolving-practice/digital-engineering-of-bio-adaptable-dental-implants.

 Evaluating Dental Biomechanics Using the Finite Element Method

 

  • Functionally Graded Porosity (FGP) enables local tailoring of the geometrical features of a lattice structure, leading to local tailoring of the mechanical behavior of the material.
    • Minimizing Stress Shielding
    • Inducing healthier and faster bone response
  • Advanced Abutment Design (AAD) which incorporate FGP into the abutment part of the implant.
    • Leads to relative micro-motion of the crown with respect to the root.
    • Produces a more natural bite feel
    • Enhances dentition/dental prosthesis interaction
    • Increases patient satisfaction
