Effects of splinted prosthesis supported a wide implant or two implants: a three‐dimensional finite element analysis

Abstract

The biomechanical advantages of using the wide implant or two implants are almost identical. The benefit of load sharing by the splinted crowns is notable only when the implants on the premolar and molar regions have different supporting ability.

Bone stress and interfacial sliding analysis of implant designs on an immediately loaded maxillary implant: A non-linear finite element study

“…It is interesting to note that the circumferential contact interfaces at the crestal cortical region of the long implant (13.5 mm) was larger than that of the short implant. Furthermore, widening the implant's diameter showed a reduction in the bone stresses at both delay loading and immediate loading treatments due to the enlarged bone-implant contact area 26 and the diminution of the bending effect by decreasing the ratio of crown and implant lengths. 18 According to the results of the present study, the increase of the implant's length and diameter could be proposed for single tooth restorations of immediately loaded maxillary implant.…”

“…The first symbol denotes the implant size: ''S'' for the standard size of implant (11.5 The material properties of implant, prosthetic crown, maxilla and grafted bone (Table 1) were assumed to be isotropic and linearly elastic. 25,26 The 129 N of the buccal oblique force 27 was applied with 308 to the long axis of the implant on the buccal cusp (Fig. 3a).…”

The influence of platform switching on the biomechanical aspects of the implant-abutment system. A three dimensional finite element study

“…Platform switched implants are also known to preserve marginal bone from stress concentration, mostly localized in the proximal layer between implant and abutment (12,13). As finite element analysis (FEA) has been extensively and successfully employed in an attempt to predict biomechanical performance of various dental implant designs (14,15), the aim of this study was to evaluate the biomechanical scenario of platform switching geometric implant-abutment configuration relative to standard configurations by means of finite element analysis. For this purpose, platform switched implant-abutment configurations were compared to implant-abutment configurations with matching diameters.…”

Previsibilidade de implantes curtos e extrascurtos unitários em mandíbula posterior atrófica

“…No estudo de Huang et al 39 (2005), a esplintagem favoreceu a dissipação das cargas em implantes com diâmetros diferentes, auxiliando na taxa de sobrevida. Em um estudo de fotoelasticidade, o autor verificou que a ferulização dos implantes proporcionou uma distribuição mais uniforme das cargas 40 .…”
