“…Our findings are consistent with a number of studies that have demonstrated the advantages of Morse-tapered internal connections compared to the traditional butt joint connection (Tesmer et al 2009;Aloise et al 2010;Tripodi et al 2012;Raoofi et al 2013). Recent studies have demonstrated that the Morse taper internal connection, with conical interference seal, provides strong resistance to applied eccentric forces and bending moments and provides improved mechanical stability to the abutment connection (Ugurel et al 2013;Hanaoka et al 2014;Schmitt et al 2014). The rigid connection and the friction between the implant and the abutment results in reduced micromovements between the two parts and thus prevents the resorption of the crestal bone (King et al 2002).…”

“…Moreover, the Morse taper connection have greater resistance to torque loss than other connection models [16]. This system seems to have less tension on the abutment screw, the cone compensates for the high stresses and protects the screw from overload [17].…”

The objective of this observational clinical study was to analyze the behavior of peri-implant tissues around cone Morse dental implants installed in the subcrestal bone position considering different clinical variables: Mucosal thickness, implant diameter, and implant length. Thirty patients were selected and included in the present study. Initially the thickness of the mucosa was measured by periapical radiographic and clinically (after the mucosal displaced). According to the planning for each treatment, implants with different dimensions (in length and diameter) were selected and used. Periapical radiographs were obtained at different times: Immediate postoperative (time t1) and 90 days after implantation (time t2). The initial stability of the implants (ISQ) was measured immediately of the implant insertion and 90 days after. The means and standard deviations of the ISQ values were in time t1 was 63.2 ± 6.99 (95% confidence interval (CI): 41 to 83) and in time t2 was 69.7 ± 7.09 (95% CI: 61 to 87). Overall mean of mesial and distal bone loss 90 days after the implantations were 1.11 ± 1.16 mm and 1.11 ± 1.15 mm, respectively. When the variables were considered, in all situations proposed, the bone loss showed differences statistically significant. In conclusion, the implant diameter and mucosal thickness variables showed an important effect on bone loss values. However, the implant length did not show an effect on the peri-implant behavior.

“…The material properties employed are detailed in Table 1 [8]. A complete osseointegration was added to both the trabecular and the cortical bone with the implant [9]. The models were subjected to an axial load of 100 N distributed throughout the region on the cantilever from the distal implant with reference to the midline and to a 30 N axial load on the implants in the inter-foramen region, both in model 1 and in model 2, as shown in Figure 3 [10,11].…”

The aim of this study was to compare the mechanical behavior of two types of prosthesis as well as the stress distribution on the prostheses’ components and the bone. Two groups were analyzed: in the first group (M1), the prothesis was composed of two implants placed at a distance of 14 mm; in the second group (M2), the prothesis was composed of three implants installed at a distance of 9.7 mm from each other. An axial load of 100 N distributed on the cantilever throughout the region from the distal implant and a 30 N axial load on the implants in the inter-foramen region, were applied in both model 1 and model 2. In both models, the stress was concentrated in the region near the neck of the implant, resulting in a maximum value of 143 MPa in M1 and of 131MPa in M2. In M1, the stress along the bone varied from of -4.7 MPa to 13,57 MPa, whereas in M2, it varied from -10 to 12 MPa. According to the results obtained, the model corresponding to six implants presented a better distribution of bone stress around the implants.

Influence of Implant/Abutment Connection on Stress Distribution to Implant‐Surrounding Bone: A Finite Element Analysis

Abstract: There was a difference in the stress location on the prosthetic components of the systems studied; however, it did not influence trabecular bone stress generation.
