“…Similarly, Papavasiliou et al (10) demonstrated that oblique forces increased the stress concentration in the implant and bone. These results are also in accordance with the literature that describes the influence of increase in crown height on the transference of occlusal forces (9,11,13,15,(18)(19)(20)(21)(22)(23)(24).…”

The purpose of this study was to assess the influence of the crown height of external hexagon implants on the displacement and distribution of stress to the implant/bone system, using the three-dimensional finite element method. The InVesalius and Rhinoceros 4.0 softwares were used to generate the bone model by computed tomography. Each model was composed of a bone block with one implant (3.75x10.0 mm) with external hexagon connections and crowns with 10 mm, 12.5 mm and 15 mm in height. A 200 N axial and a 100 N oblique (45°) load were applied. The models were solved by the NeiNastran 9.0 and Femap 10.0 softwares to obtain the results that were visualized by maps of displacement, von Mises stress (crown/implant) and maximum principal stress (bone). The crown height under axial load did not influence the stress displacement and concentration, while the oblique loading increased these factors. The highest stress was observed in the neck of the implant screw on the side opposite to the loading. This stress was also transferred to the crown/platform/bone interface. The results of this study suggest that the increase in crown height enhanced stress concentration at the implant/bone tissue and increased displacement in the bone tissue, mainly under oblique loading.

“…Studies testing survival rates for 1.3:1 (Schulte et al, 2007), 0.8:1 to 3.0:1 (Rokni et al, 2005), and 2:1 and 3:1 (Blanes et al, 2007) implant-to-crown ratios found similar results, with bone resorption at normal levels.…”

“…In this way, the use of implants to rehabilitate posterior regions of maxillae or mandibles often requires the use of short implants to short implants (Srinivasan et al, 2012) and to the fabrication of a higher prosthetic crown (Schulte et al, 2007;Tawil et al, 2006). From a biomechanical point of view, the literature indicates that increase in prosthetic crown height can be a dangerous factor to the stress distribution as determined by mechanical technique analysis (Nissan et al, 2011) and by 3-D finite element analysis (Sütpideler et al, 2004).…”
