“…Since bone tissue seems to respond to strains (Huiskes and Hollister, 1993), and strains are induced by stresses in adjacent structures such as dental implants, the advent of implantology brought the proliferation of FE analysis studies related to the effects of stresses created by dental implants on the surrounding bone (Kitoh et al, 1978;Takahashi et al, 1978;Weinstein et al, 1980;Cook et al, 1982a,b;Borchers and Reichart, 1983;Rieger et al, 1989;Siegele and Soltesz, 1989;El Charkawi et al, 1990;Rieger et al, 1990;Van Rossen et al, 1990;Mihalko et al, 1992;CIelland et al, 1991;Meijer et al, 1995 (1997) of changes in bone geometry on implant-derived stress distributions (Widera et al, 1976), a prediction that was corroborated in more recent studies (Borchers and Reichart, 1983;Clelland et al, 1993). These findings, in connection with histomorphometric ones, led to the application of more sophisticated FE analyses which combined the so-called global strain environment induced by implant loading with detailed, micromechanical strain predictions of the implant/bone interface (Ko et al, 1992b).…”

In this paper, we provide a review of mechanical finite element analyses applied to the maxillary and/or mandibular bone with their associated natural and restored structures. It includes a description of the principles and the relevant variables involved, and their critical application to published finite element models ranging from three-dimensional reconstructions of the jaws to detailed investigations on the behavior of natural and restored teeth, as well as basic materials science. The survey revealed that many outstanding FE approaches related to natural and restored dental structures had already been done 10-20 years ago. Several three-dimensional mandibular models are currently available, but a more realistic correlation with physiological chewing and biting tasks is needed. Many FE models lack experimentally derived material properties, sensitivity analyses, or validation attempts, and yield too much significance to their predictive, quantitative outcome. A combination of direct validation and, most importantly, the complete assessment of methodical changes in all relevant variables involved in the modeled system probably indicates a good FE modeling approach. A numerical method for addressing mechanical problems is a powerful contemporary research tool. FE analyses can provide precise insight into the complex mechanical behavior of natural and restored craniofacial structures affected by three-dimensional stress fields which are still very difficult to assess otherwise.

“…A variety of implant shapes and prosthetic concepts have been investigated in the search for improved shapes to enhance the applicability of implants. [10,11] The choice of framework is important in clinical dental implant-supported prosthesis. Frequently, in practice metal-ceramic combinations are used.…”

The paper presents three-dimensional (3D) finite element models of straight and angled implants and their zirconium-based superstructures. The key objective was to compare the influence of different loading conditions on the stress distribution of straight and angled implants and the zirconia frameworks. 3D finite element straight-and angled-implant models of a mandibular section of bone with missing second molars and their zirconium-based superstructures were used. The straight and angled implants were 4.7 £ 13-mm screw-type dental implant systems. Total loads of 300 N were applied in a vertical direction and in an oblique (30 to the vertical) direction buccolingually. Maximum and minimum von Mises stress values of the titanium structures (abutment and implant body) and zirconia frameworks were calculated. When the two groups were examined, the highest stress value was in the zirconia framework of the angled implant-supported model with an oblique loading force (731.46 MPa). The lowest stress values were concentrated in the straight implant-supported model. Thus, the stress values in the angled implant-supported crown were higher than those in the straight implant-supported model. Stress values with oblique loading forces were higher than the values with vertical loading forces. The highest stress value in the zirconia framework was similar to the ultimate strength of the zirconia.

“…An occlusal load of 113 N was applied at the center of abutment with the direction of 11 degrees with respect to the main axis, and a moment of 90 N.mm to mimic the biting force on the prosthesis. The elastic moduli of the implant system (Ti), the cortical bone, and the trabecular bone were set to 113, 13 and 1 GPa, respectively (Rieger et al, 1989a;Steinemann, 1996).…”

“…Holmgren et al (1998) reported that the stepped implant design levels out the stress distribution better than a cylindrical design. Rieger et al (1989aRieger et al ( , 1990aRieger et al ( , 1990b investigated the effect of implant geometry and the elastic modulus of the implant materials on the stress distribution for different implant designs. A tapered design made of a material with high elastic modulus was concluded to be the most suitable design in their study.…”
