The aim of this study was to investigate stresses resulting from different thicknesses of grit blast (GB) and micro arc oxidized (MAO) treated layers at the interface between temporomandibular joint (TMJ) implants and bones using three-dimensional (3D) fi nite element models. Several studies have investigated fi nite element models for TMJs, but few have examined a model for TMJ implants with treated layers. The maximum stresses in the bone occurred at the position of the fi rst screw. Data analysis indicated a greater decrease in this stress in the case of using TMJ implants with MAO treated layers, and the stresses decreased with increasing layer thicknesses. Results confi rmed that the treated layers improve biomechanical properties of the TMJ implants and release abnormal stress concentration in them. The results of this study off er the potential clinical benefi t of inducing superior biomechanical behavior in TMJ implants.

“…Feldspathic porcelain (Ceramco II, Dentsply, Burlington, NJ) was used for the occlusal surfaces. Table 1 lists the Young's modules and Poisson ratios of cortical bone (D2), [22] spongious bone (D4), [22] titanium (implant body C abutment), [22] zirconia, [10] porcelain [23] and cement. [24] The vertical and oblique (30 to the vertical) load applied in the model was 200 N, based on the literature.…”

“…Using a 3D FE analysis technique, Sevimay et al [23] investigated the effects of bone quality on the stress distribution in an implant and implant-supported crown. They showed the presence of lower stresses with D1 and D2 bone qualities and increased stresses for D3 and D4 bone qualities because trabecular bone was weaker and less resistant to deformation.…”

“…They showed the presence of lower stresses with D1 and D2 bone qualities and increased stresses for D3 and D4 bone qualities because trabecular bone was weaker and less resistant to deformation. [1,23] Thicker cortical bone (D2) reduces stress concentration around the implants. [33,34] The results of the present study are consistent with the studies above in terms of stress values being greater with trabecular bone (D4) than with cortical bone (D2).…”

The aim of this in-silico study was to compare stress distributions in implants and zirconia frameworks of mandibular and maxillary implant-supported crowns. For comparison, vertical and oblique loading forces were used. Three-dimensional finite-element implant models of a mandibular section of bone (D2) and a maxillary section of bone (D4) with missing second molars and their zirconium-based superstructures were used. Zimmer dental implants of 13 mm in length and 4.7 mm in diameter were modelled. A load of 200 N was applied toward vertical and oblique (30 to the vertical) directions. Maximum and minimum von Mises stress values of the implants and the zirconia framework were calculated. The highest stress value was concentrated in the zirconia framework of the maxillary implant-supported model with the oblique loading force (301.17 MPa). The lowest stress value was concentrated in the mandibular implant-supported model. And the stress values in the maxilla were higher than in the mandible. The maxilla (D4) showed higher stress values than in the mandible (D2), because the trabecular bone is weaker and less resistant to deformation than the cortical bone. Stress values with oblique loading forces were higher than with vertical loading forces. Because of the high Young's modulus of zirconia (low elastic properties), zirconia frameworks showed higher stress values than the implants.Keywords: finite element analysis (FEA); stress distribution; zirconia framework; bone quality; vertical and oblique loading force 3D three dimensional D2 mandibular section of bone D4 maxillary section of bone FE finite element FPDs fixed partial dentures Y-TZP yttrium oxide partially stabilized

“…2 However, there are a number of factors that can cause failure of implant treatments, such as surgical and/or systemic complications, in addition to poor bone quality and density that may compromise the initial stability of the implant, which is a prerequisite for the success of osseointegration. 3,4 The forces that occur at the implant-bone interface can promote micromovements in the implant and are the most damaging ones in the first moments of implant healing. 5 Furthermore, the primary stability of the implant also depends on the quality, density, and thickness of available cortical bone tissue at the surgical site.…”
