“…Excessive loads on the implant lead to high mechanical stimulus at the interface and transfer stress to the bone causing original bone modeling/remodeling equilibrium, producing premature failure over time is well known as the "mechanostat theory" [37][38][39][40][41][42] . Strain is accepted as the mechanical stimuli for bone remodeling around dental implants.…”

This study developed a customized surgical template under mechanical consideration for molar intrusion. Two finite element (FE) models were analyzed for the primary stability under 100 gf traction forces with one mini-screw inserted at the buccal side in horizontal and another in palatal side with two optional positions at 60° (P60) or 15° (P15) angles with inclination toward the molar occlusal surface. The surgical template was generated using rapid prototyping (RP) printing for the clinical application based on improved primarily stability model. The surrounding bone strains for models P15 and P60 were far lower than the bone remodeling critical value. Model P60 presented much lower micro-motion in the screw/bone interface and the screw head displacement than those values in model P15. Using FE analysis for biomechanical evaluation and combining with CT image, image superimposed method and CAD technique can fabricate accuracy/security customized surgical template for mini-screws with better primary stability.

“…According to Misch and Kircos (6) and Lekholm and Zarb (7) classifications, low quality bone corresponds to bone type 3 and 4. Implant design play a key role in order to obtain good bone to implant contact and particularly when immediate loading is needed (8). Several studies reported higher PS in parallel implants when compared to tapered ones (9,10), while other studies found the opposite (11,12).…”

Background: Primary stability (PS) is a key factor for implant survival rate and depends on implant design or bone quality. The aim of this study was to compare different thread designs implants, evaluating PS with periotest values (PV) and implant stability quotient (ISQ) values through resonance frequency analysis (RFA). Material and Methods: A total of 60 implants (Radhex®, Inmet-Garnick S.A., Guadalajara, Spain) were placed in freshly bovine ribs in vitro. Two designs were used: 30 tapered body with single thread design (PHI) and 30 tapered body with double thread design implants (PHIA). Both designs were 4mm wide and 12mm long. Implants were placed according to manufacturer's guidelines. Osstell™ and Periotest® devices were used to evaluate PS by a blinded independent observer. Computed tomographies (CTs) of the ribs were made (BrightSpeed Series CT systems, GE Healthcare, Milwaukee, WI, USA) and bone quality surrounding each implant was evaluated in Hounsfield Units (HU) using Ez3D Plus software (Vatech Co., Korea). Bone quality was classified according to Misch and Kircos in D1, D2, D3 or D4. Results: All implants were mechanically stable. Only implants placed in D3 bone (350-850 HU) were selected for the study: 28 PHI and 26 PHIA. The one way ANOVA showed significant difference (p < 0.005) among two implants designs in ISQ values (61,55 ± 6,67 in PHI and 68,94 ± 5,82 in PHIA). No significant difference (p = 0,171) was shown in PV between two designs 47 ± 1,77 ± 0,87 in PHIA). Conclusions: Higher PS was found using Osstell™ device in implants with double thread design (PHIA) in comparison to implants with single thread design (PHI) in D3 bone.

“…[10][11][12][13] For implant materials, in addition to resistance against corrosion induced by the chemically aggressive human body environment, mechanical performance related parameters, such as high strength, improved fatigue resistance, and fracture toughness, are also important, especially considering loading conditions that can sometimes become intense. [14][15][16][17] For instance, sudden impact loads prompted by falling, jumping, or other causes may lead to serious injuries and bone fractures in various body parts, such as hip or knee joints, [18][19][20][21][22] or dental implants. [4][5][6] Thus, understanding the impact response is crucial for a potential implant material for guaranteeing the safety and satisfactory mechanical performance of the implant during service.…”

Microstructure-based modeling of the impact response of a biomedical niobium–zirconium alloy

et al. 2014

This article presents a new multiscale modeling approach proposed to predict the impact response of a biomedical niobium-zirconium alloy by incorporating both geometric and microstructural aspects. Specifically, the roles of both anisotropy and geometry-based distribution of stresses and strains upon loading were successfully taken into account by incorporating a proper multiaxial material flow rule obtained from crystal plasticity simulations into the finite element (FE) analysis. The simulation results demonstrate that the current approach, which defines a hardening rule based on the location-dependent equivalent stresses and strains, yields more reliable results as compared with the classical FE approach, where the hardening rule is based on the experimental uniaxial deformation response of the material. This emphasizes the need for proper coupling of crystal plasticity and FE analysis for the sake of reliable predictions, and the approach presented herein constitutes an efficient guideline for the design process of dental and orthopedic implants that are subject to impact loading in service.
