“…Standard dental implants have a cylindrical geometry with a helical screw track and a single root structure. 50 However, because of the poor machinability of the NiTi alloy 51,52 and the lack of a significant effect on the targeted SME, the implant model was prepared without screw traces. As seen in Figure 2, towing to the hollow structure created, both artificial tooth roots were obtained, and the bone− implant contact surface area was increased.…”

Design and material research continues to increase dental implants’ success rates, which is a widely applied treatment type. The size and morphology of the implant–bone interface are essential for implant stability. Our study produced a dental implant with two artificial tooth roots from NiTi alloy to increase the implant–bone contact surface. The properties of NiTi alloy, such as transformation temperature and composition, were determined by material characterization tests. Using NiTi alloy’s shape memory effect, these artificial roots at body temperature were programmed with appropriate heat treatments for the self-fitting feature. Dental-implant-like models are coated with TiN to prevent Ni ion release. The corrosion tests were performed in Ringer’s solution to determine the effect of TiN coating on Ni ion release. The nickel ion emission values showed that the TiN coating inhibited the release. In addition, it was determined that the TiN coating increased the shape memory transformation time of the NiTi alloy. In in vitro tests of NiTi and TiN-coated NiTi implants, it was observed that they completed self-fitting by deforming the trabecular bone, but the placement in the cortical bone was not complete. During the use of a shape memory implant, it should complete its transformation without contacting the cortical bone and should not cause a stress concentration.

“…Stress analysis calculated by FE method showed an excellent distribution of bone around implant while any forces applied. Some articles provided stress distribution any type of implant [ 16 , 17 , 18 ]. If it were possible to perform virtual implant therapy simulations using 3D X-ray CT scans of live individuals prior to the actual procedure, treatment planning for implants could be carried out with a high level of mechanical predictability, which could become a new diagnostic standard in clinical practice.…”

A three-dimensional (3D) finite element (FE) model of the mandibular bone was created from 3D X-ray CT scan images of a live human subject. Simulating the clinical situation of implant therapy at the mandibular first molar, virtual extraction of the tooth was performed at the 3D FE mandibular model, and 12 different implant diameters and lengths were virtually inserted in order to carry out a mechanical analysis. (1) High stress concentration was found at the surfaces of the buccal and lingual peri-implant bone adjacent to the sides of the neck in all the implants. (2) The greatest stress value was approximately 6.0 MPa with implant diameter of 3.8 mm, approx. 4.5 MPa with implant diameter of 4.3 mm, and approx. 3.2 MPa with implant diameter of 6.0 mm. (3) The stress on the peri-implant bone was found to decrease with increasing length and mainly in diameter of the implant.

“…Since there is no clear result in the literature, studies on abutment design and material are needed. Finite element analysis (FEA) can be used to evaluate stress‐related outcomes to model clinical conditions and assess biomechanics in implant dentistry 20–23 . The purpose of this 3D FEA study is to analyze the stress distributions on the implant and its components with abutments produced with different angles, properties and materials, and strain distribution on the simulated bone where the implant is placed.…”

The first null hypothesis was that the type, angle, and material properties of the abutment would not affect the stress on the implant components and the strain on the simulated bones.…”

Purpose:The optimal abutment material and design for an angled implant-abutment connection in the esthetic zone is unclear. The purpose of this finite element analysis (FEA) study was to compare different abutment models by evaluating the stress values in the implant components and strain values on the simulated bone around an anterior maxillary implant with different angled abutment models and loading conditions. Materials and Methods: One Ø3.5×12-mm implant was placed in 3D FEA models representing the anterior left lateral segment of the maxilla. Three different contemporary implant models were created with 17°or 25°angled abutments (Ti base abutment, zirconia abutment, and titanium abutment) and 3D-modeled. The implant abutment model was an angled Ti base abutment (TIB), an angled zirconia abutment (ZIR), or an angled titanium abutment (TIT). Vertical and oblique loads of 100 N for the central incisors were applied as boundary conditions to the cingulum area and incisal area in a nonlinear FEA. Results:The TIB model resulted in reduced stress conditions. According to the von Mises stresses occurring on the screw, abutment, crown, and implant, especially under oblique loads, the TIB model was exposed to less stress than the ZIR or TIT models. Strain values in simulated cortical and trabecular bones were obtained lower in the TIB model. Conclusions: When a standard implant was placed in the esthetic zone at an increased angle, the implants, abutments, and screws had more unfavorable stress levels; therefore, using a Ti-base abutment may reduce stress. The amount of contact surface of the implant with the simulated cortical bone is also an important factor affecting stress and strain.
