Biomechanical effects of the implant material and implant–abutment interface in immediately loaded small-diameter implants

Abstract

A commercially pure titanium implant with an internal connection has the potential to reduce the risk of implant failure of small-diameter implant related to biomechanical complications.

Biomechanical evaluation of one-piece and two-piece small-diameter dental implants: In-vitro experimental and three-dimensional finite element analyses

“…13 However, high long-term clinical survival rates for two-piece smalldiameter implants (up to 95%) have been reported. 8,14,15 Many studies 16,17 have examined the influences of the small diameter of implants based on biomechanical factors. However, until now, there is no study investigating the effect of implants with both small-diameter designs and onepiece or two-piece concepts on biomechanical performance.…”

Biomechanical investigations of the expanded platform-switching concept in immediately loaded small diameter implants

“…5,6 The Kruskal-Wallis test and multiple comparisons with the Bonferroni test were used to assess differences. All analyses were performed using commercial statistical software (SAS v9.1; SAS Institute) (a=.05).…”

“…5,6 Each loading procedure involved applying a force of 190 N 20 to the cylindrical abutment using a universal testing machine (JSV-H1000; Japan Instrumentation System) with a head speed of 1 mm/min (Fig. 3).…”

“…5,6 Density of the trabecular bone used in this study was simulated as type 2 (D2) bone, 16 based on the bone density classification of Misch. 17 The thickness of the cortical bone was referred to in the study by Hahn,18 which indicated that D2 bone was associated with 2.5 to 4 mm of cortical bone height.…”

“…5,6 In order to simulate the interface condition of an immediately loaded implant, the interface between implant and bone was prepared for contact only. After the implant was placed, a wireless resonance frequency analyzer (Osstell ISQ; Osstell AB) was used to measure the implant stability quotient (ISQ).…”
