The objective of this study was to investigate the mechanical characteristics of implant–abutment interface design in a dental implant system, using nonlinear finite element analysis (FEA) method. This finite element simulation study was applied on three commonly used commercial dental implant systems: model I, the reduced-diameter 3i implant system (West Palm Beach, FL, USA) with a hex and a 12-point double internal hexagonal connection; model II, the Semados implant system (Bego, Bremen, Germany) with combination of a conical (45° taper) and internal hexagonal connection; and model III, the Brånemark implant system (Nobel Biocare, Gothenburg, Sweden) with external hexagonal connection. In simulation, a force of 170 N with 45° oblique to the longitudinal axis of the implant was loaded to the top surface of the abutment. It has been found from the strength and stiffness analysis that the 3i implant system has the lowest maximum von Mises stress, principal stress and displacement while the Brånemark implant system has the highest. It was concluded from our preliminary study using nonlinear FEA that the reduced-diameter 3i implant system with a hex and a 12-point double internal hexagonal connection had a better stress distribution, and produced a smaller displacement than the other two implant systems.

“…A customized jig was designed with an adjustable screwing device so that a 45‐degree lingual oblique force could be applied in the experiments. Each loading procedure involved applying a force of 170 N 21 to the conical abutment using a universal testing machine †† with a head speed of 1 mm per minute (Fig. 1C).…”

“…The transducer has high linearity, low hysteresis and good temperature stability for each axis. The characteristics of the transducer are described in detail elsewhere (13). The three dimensions were defined as vertical ( z ‐axis), antero‐posterior ( y ‐axis) and mediolateral ( x ‐axis).…”

“…However, because in vivo measurements are problematic due to the transducer size, measurements in which the transducer is directly inserted into an abutment tooth crown have only recently been undertaken. We recently developed a 3-dimensional (3-D) force-measuring device that enables in vivo time series measurement of the force exerted on a tooth (13). With this device, we can measure compressive and tensile forces along three axes.…”

The 3-D tensile and compressive forces exerted on a tooth were measured in vivo during function using a force-measuring device including a piezoelectric transducer. The device was mounted on the maxillary left second molar of a healthy male subject; the subject tooth had been endodontically treated and prepared for metal abutment and a crown. The 3-D forces were expressed as a vector of the coordinates based on the Frankfort horizontal (x-y) and sagittal (y-z) planes. The device captured the sequential changes in the forces. The directions of the forces changed during not only chewing a caramel or a peanut but also maximum voluntary clenching (MVC). As the magnitudes of the force increased during both MVC and caramel chewing (CaC), the force vector tended to correspond to the direction of the palatal root, medially and posteriorly. The compressive forces during MVC and caramel and peanut chewing were 173.29+/-15.32, 146.3+/-14.7 and 57.7+/-35.7 N, respectively. The force vector during MVC was directed from the crown to the root medially at an angle of 10.27+/-1.00 degrees from the y-z plane and posteriorly at an angle of 3.18+/-0.85 degrees from the x-z plane to the perpendicular line of the F-H plane. There were significant differences in the behaviour of the compressive forces between clenching and chewing. The tensile force was recorded during CaC, not peanut chewing.
