“…The present study showed similar results to those of a previous study (4), in which the increase of the insertion torque generates higher compressive stress concentrations to the peri-implant bone tissue. In the present study, for the cancellous bone tissue, the increase of insertion torque (from 30 to 80 Ncm) showed an increase of 1175% for the maximum principal stress and 266% for the maximum principal strain.…”

“…These failures may have biological causes, such as periimplantitis and systemic diseases. In addition, biochemical factors can negatively influence implant success; for instance, bone over heating during the surgical procedure, occlusal overload, besides the effects of tensile strength, shear and compressive stresses in the peri-implant bone tissue (4).…”

“…Excessive tension may cause irreversible damage to the periimplant bone tissue (6). Conversely, too low tension may unsatisfactorily stimulate the bone repair process (4). Recent computerized simulations have suggested that compressive stresses and hydrostatic tensions of the interstitial liquid may modulate tissue differentiation and bone remodeling (4,7,8).…”

“…Conversely, too low tension may unsatisfactorily stimulate the bone repair process (4). Recent computerized simulations have suggested that compressive stresses and hydrostatic tensions of the interstitial liquid may modulate tissue differentiation and bone remodeling (4,7,8). Byrne et al (7), using mathematical models about cellular differentiation in bone repair, verified that the stress increase changes the bone repair process, reducing the amount of newly formed bone tissue by 23% and increasing the amount of cartilage by 21%.…”

The aim of this study was to evaluate the influence of the high values of insertion torques on the stress and strain distribution in cortical and cancellous bones. Based on tomography imaging, a representative mathematical model of a partial maxilla was built using Mimics 11.11 and Solid Works 2010 softwares. Six models were built and each of them received an implant with one of the following insertion torques: 30, 40, 50, 60, 70 or 80 Ncm on the external hexagon. The cortical and cancellous bones were considered anisotropic. The bone/implant interface was considered perfectly bonded. The numerical analysis was carried out using Ansys Workbench 10.0. The convergence of analysis (6%) drove the mesh refinement. Maximum principal stress (σ max ) and maximum principal strain (ε max ) were obtained for cortical and cancellous bones around to implant. Pearson's correlation test was used to determine the correlation between insertion torque and stress concentration in the periimplant bone tissue, considering the significance level at 5%. The increase in the insertion torque generated an increase in the σ max and ε max values for cortical and cancellous bone. The σ max was smaller for the cancellous bone, with greater stress variation among the insertion torques. The ε max was higher in the cancellous bone in comparison to the cortical bone. According to the methodology used and the limits of this study, it can be concluded that higher insertion torques increased tensile and compressive stress concentrations in the periimplant bone tissue.

SUMMARYThe rehabilitation of edentulous patients is today a challenge for the clinicians. The healthy of the hard and soft issue may be considered a fundamental element for having long-term results. The dental implant progresses about the predictable and safe results made this technique chosen from a large group of practitioners. However some problems related intraoperative and postoperative conditions may create discomfort on the patients and consequently to the clinician. The unfavourable results are often related to the bone tissue quality but sometime the dental implant shape and the prosthesis framework may undergo to technical difficulties. The purpose of this work is, through the use of appropriate FEM models, to analyse the effect of all these parameters in the construction of a prosthesis type "Toronto", evaluating all the surgical and prosthetic components in order to direct the choices made by the surgeon and to optimize the distribution of loads reducing the patient's discomfort and having a long term clinical success.

Dental implantation surgery has been progressed as one of the most efficient prosthetic technologies, however, it still fails very often and one of the main causes is the large difference between implant mechanical properties and those in welcoming bony tissues, making it problematical in osseointegration and bone remodeling. Biomaterial and tissue engineering research shows that there is a requirement in developing implants with Functionally Graded Materials (FGM). Indeed, the great potential of FGM lies not only in the field of bone tissue engineering but also in dentistry. To improve the acceptance of dental implants inside the living bone, FGM were proposed to step up the challenge of ensuring a better match of mechanical properties between biologically and mechanically compatible biomaterials. The aim of the present work is to investigate mandibular bone remodeling induced by FGM dental implant. Three‐dimensional (3D) mandibular bone structure around an osseointegrated dental implant has been created to analyze the biomechanical behavior of the bone–implant system depending on implant material composition. In order to implement the numerical algorithm into ABAQUS software, UMAT subroutines and user‐defined material were employed. Finite element analysis have been conducted to determine the stress distributions in implant and bony system, and to evaluate bone remodeling induced by the use of various FGM and pure titanium dental implants over the period of 48 months.
