“…Both cortical and trabecular (cancellous) bone properties have been extensively analyzed in vivo and ex vivo, with a variety of static and dynamic methods [ 11 , 12 , 13 , 20 , 21 , 22 , 28 , 29 , 30 , 31 ]. Some studies were focused more on simplified engineering values, whereas others also considered bone anisotropy and microstructure effects in more sophisticated detail.…”

“…It is also known that the success of a dental implant depends on a variety of biomechanical factors, including the design and position of the implant, implant-abutment connection, cantilever length, surface roughness, bone quality and type, depth of insertion, arch configuration, the nature of bone–implant interface, and occlusal conditions [ 1 , 2 , 9 , 12 , 14 , 29 ]. Whereas such biomechanical factors have been simulated earlier, the results are often contradictory, due to differences in model parameters, construction, materials models selection and meshing [ 29 ].…”

“…In regard to mechanical stimuli, many reported studies are expressing acting stress in an equivalent format such as von Mises stress [ 17 , 29 , 31 , 33 , 44 ]. However, the use of von Mises stress has substantial limitations: it has been most widely applied for engineering problems as a yield criterion, stating that the yielding of a material occurs once the second deviatoric stress invariant reaches a critical (yield stress) value [ 17 , 21 , 31 , 45 ].…”

“…Because the tissue’s behavior in tension and compression is different and often non-linear, the use of symmetric stress characterization is a clear oversimplification. Indeed, authors [ 29 ] noted that besides single values alike von Mises stress, the magnitudes of the stress concentrations, stress distribution, and displacement components of specific points should be analyzed as they could provide a valuable information about the deformation of the model and assist in the interpretation of the results.…”

Dental implants’ success comprises their proper stability and adherence to different oral tissues (integration). The implant is exposed to different mechanical stresses from swallowing, mastication and parafunctions for a normal tooth, leading to the simultaneous mechanical movement and deformation of the whole structure. The knowledge of the mechanical properties of the bone and gingival tissues in normal and pathological conditions is very important for the successful conception of dental implants and for clinical practice to access and prevent potential failures and complications originating from incorrect mechanical factors’ combinations. The challenge is that many reported biomechanical properties of these tissues are substantially scattered. This study carries out a critical analysis of known data on mechanical properties of bone and oral soft tissues, suggests more convenient computation methods incorporating invariant parameters and non-linearity with tissues anisotropy, and applies a consistent use of these properties for in silico design and the application of dental implants. Results show the advantages of this approach in analysis and visualization of stress and strain components with potential translation to dental implantology.

Biomechanical analyses of one‐piece dental implants composed of titanium, zirconia, PEEK, CFR‐PEEK, or GFR‐PEEK: Stresses, strains, and bone remodeling prediction by the finite element method

et al. 2021

This work aimed to assess the biomechanics, using the finite element method (FEM), of traditional titanium Morse taper (MT) dental implants compared to one-piece implants composed of zirconia, polyetheretherketone (PEEK), carbon fiber-reinforced PEEK (CFR-PEEK), or glass fiber-reinforced PEEK (GFR-PEEK). MT and one-piece dental implants were modeled within a mandibular bone section and loaded on an oblique force using FEM. A MT implant system involving a Ti6Al4V abutment and a cp-Ti grade IV implant was compared to one-piece implants composed of cp-Ti grade IV, zirconia (3Y-TZP), PEEK, CFR-PEEK, or GFR-PEEK. Stress on bone and implants was computed and analyzed while bone remodeling prediction was evaluated considering equivalent strain. In comparison to one-piece implants, the traditional MT implant revealed higher stress peak (112 MPa). The maximum stresses on the onepiece implants reached $80 MPa, regardless their chemical composition. MT implant induced lower bone stimulus, although excessive bone strain was recorded for PEEK implants. Balanced strain levels were noticed for reinforced PEEK implants of which CFR-PEEK one-piece implants showed proper biomechanical behavior. Balanced strain levels might induce bone remodeling at the peri-implant region while maintaining low risks of mechanical failures. However, the strength of the PEEKbased composite materials is still low for long-term clinical performance.biomechanics, dental implants, dental materials, finite elements analysis, implant design 1 | INTRODUCTION Titanium dental implants have been increasingly used to replace missing teeth within a high long-term success rate as reported in literature. [1][2][3][4] Dental implants are often composed of two components: the endosseous implant itself and the abutment. The connection between traditional abutment and endosseous implants can be commonly achieved by screwing the abutment in the inner implant surfaces up to a maximum adequate torque or within a Morse taper (MT) effect, in which an applied preload generates stresses that keep the components attached to each each other. 5,6 At last, a single-or multi-unit prosthesis is cemented and/or screwed over the abutment to replace the coronal dental structure. MT implant systems typically reveal higher mechanical stability due to their connection on contacting surfaces and distribution of stresses to the bone.
