Impacts of 3D bone-to- implant contact and implant diameter on primary stability of dental implant

Abstract

This study revealed how the implant diameter and the three-dimensional (3D) BIC influence the primary stabilities of dental implant. ITV and PTV were more sensitively influenced by the implant diameter than ISQ. The pBICA and BICA seem to be more important than 3D BIC % for using wider implant in treatment plan, since those two parameters are highly predictive of variations in the primary stability of dental implant.

Effects of implant length and 3D bone-to-implant contact on initial stabilities of dental implant: a microcomputed tomography study

“…The measurement approach of 3D BIC parameters were the same with our previous study. [ 24 ] As stated by Stoppie et al’s study, [ 25 ] a thin layer of metal artefact around an metallic implant was existing between the inserted implant and bone in the micro-CT images. [ 25 ] In order to prevent the problem of artefact, in this study, the artificial bone specimens and dental implants were scanned separately by micro-CT (SkyScan 1076, Skyscan, Aartselaar, Belgium) at the same resolution (17.2 × 17.2 × 17.2 μm3) but with different scanning voltages and currents (89 kV and 112 μA for dental implants, 49 kV and 149 μA for artificial bones).…”

Modeling the effect of osseointegration on dental implant pullout and torque removal tests

“…Finite element (FE) modeling has been used to assess dental implants secondary stability and/or the mechanical behavior of the jaw bone as a result of the loads prescribed by the implant (see eg, [15][16][17] ) Those studies usually focused on bone-implant interfacial properties, when the interface was characterized by a specific strength, failure strain, and damage model, 15 or in fewer cases by a coefficient of friction by, for example, 18,19 Those studies did not address specifically the 3-dimensional geometrically random nature of the bone to implant attachment, except for limited ex vivo studies as. 20 In this work, we study various percentages of bone to implant bonding (tie) using numerical FE simulations. While evolutions of the bone mechanical properties are not explicitly taken into account, emphasis is put on the 3-dimensional variable extent of the boneimplant bonding, and its influence on the measurable extraction and torque loads, seeking to obtain a quantitative relationship.…”

Comparative Evaluation of Primary Stability between Different Diameters Multi-Scale Roughness Dental Implant by Solid Rigid Polyurethane Simulation

“…The choice of the appropriate implant diameter is clinically determined by prosthetic factors, aesthetics, the residual thickness of the bone ridge, and the distance between adjacent elements [41]. A minimum distance of 1.4-2mm should be always maintained between the marginal bone and the implant surface [42].…”
