A three dimensional finite element study on dental implant design

Abstract

Implant diameter and length are the most effective parameters affecting stress distribution in surrounding bones. In order to extract simplified design equations to better understand implants behavior, 25 different implant designs with gradual increase in diameter and length were analyzed in 3D using Finite Element Method. Four types of loadings were applied on each design: tension of 50 N, compression of 100 N, bending of 20 N, and torque of 2 Nm to derive design curves.Analysis of results showed that increasing implant diameter and length generate better stress distribution on spongy and cortical bones. Approximate design equations and curves were obtained as a result of this study.

Does Implant Fixed Restoration Can Reverse The Physiological Route Of Mandibular Bone Resorption Of The Posterior Edentulous Area For The Completely Edentulous Patients?: Systematic Review

“…However, evaluating posterior mandibular bone height change after usage of implant supported prostheses either fixed or removable were little in the literature and lack of consistency which might cause researchers to mislead to analyze data from the different studies. [2,9,10,[17][18][19][20] This systematic review was conducted to compare amount of posterior mandibular bone height changes of fixed implant restorations versus implant overdentures. This included only one RCT10 and two prospective cohort studies which are considered of a lower level of evidence than that of RCTs.…”

New Trends in Dental Biomechanics with Photonics Technologies

“…FEM was applied to investigate the residual shrinkage stress distributions in dental materials [16,17]. Other studies are related to the simulation of dental implant biomechanics, related to the osteointegration and load mechanism transfer in dental implant-supported prostheses [18][19][20]. This methodology was also applied in prosthodontic and endodontic studies [21][22][23].…”

Biomechanical Investigation of Titanium and Zirconia Dental Implants

“…Chang simplified bone structure to a cubic shape, which was covered with a 2 mm layer of cortical bone [12]. El Anwar simplified bone geometry and simulated as a cylinder that consists of two co-axial cylinders [13]. The model may be two-dimensional.…”

“…Artificial materials for example implant body, abutment and dental crown, can be modeled quite accurately. Materials are considered to be homogenous and isotropic [11][12][13][14]. Loading conditions can be simulated with axial and non-axial forces.…”

“…Loading conditions can be simulated with axial and non-axial forces. If model consists only of bone and implant body, loading forces act on a crest module [13,14]; if model consists all parts including dental crownloading forces act on the surface of dental crown [12]. Dental implants are subjected to loading conditions from 25 N up to 500 N at 15-45 degrees angle [11][12][13][14].…”
