| description | Objective To investigate the influence of micro-implant length and screw angle on stress distribution and displacement of micro-implant bone interface when micro-implant was implanted in zygomatic alveolar ridge and bear a certain load, in order to provide certain theoretical basis for micro-implant selection and further optimization design in clinical practice. Methods A three-dimensional finite element model of the jaw in the zygomatic alveolar ridge region was established using ANSYS software. At the same time, 35 kinds of micro-threaded implants with length of 8, 9, 10, 11, 12 mm and angle of 30°, 45°, 60°, 75°, 90°, 105°, 120° were established. The micro-implant was simulated to be implanted in the jaw bone, and the implantation model was established. Stress analysis was performed on the bone interface of the micro-implant. Results The maximum stress of micro-implant bone interface occurred in the bone cortex. The maximum stress value of buccal cortical bone, cancellous bone and micro-implant displacement decreased with the increase of screw length. The angle of screw had little effect on the maximum stress and displacement of micro-implant-bone interface. Conclusion The screw length has an impact on stress distribution of micro-implant bone interface. The micro-implant with longer length can improve its stability in zygomatic alveolar ridge. |
