Screw implant interface during healing biomechanics
Some typical areas of the healing process unit, which unit a and b in the cortical bone, C, and d in the cancellous bone. Element in the healing phase of a stress in a better environment to achieve full healing, but function stage, due to increased levels of stress arising bone resorption, leading to a sharp decline in unit modulus. Element b in the healing phase due to higher stress environment is not fully healed, in the functional stage of the stress level is rising because of serious bone resorption. Unit C,[link widoczny dla zalogowanych], Unit d reached in the healing stage of a full healing, but the element d stress due to low initial healing phase is going through a healing time, when the stress rises to stress the window began to heal. Figure 6 also clear that the role of the lateral force some seriously aggravated the cortical bone resorption phenomenon. Figure 5 functional stages in the healing phase,[link widoczny dla zalogowanych], and trabecular bone and cortical bone healing process , ~ l,[link widoczny dla zalogowanych],. ,,-__ First 1OOoo Chao swallow 5Oooli,. -02 O port 0 handsome charm Park O60o drag curve f ℃ step (11) Figure 6,[link widoczny dla zalogowanych], the healing process of a typical unit 273 discussed results show that in the healing phase,[link widoczny dla zalogowanych], cancellous bone is not part of the bottom of the healing implant region, mainly due to Low stress caused. The cortical bone did not heal in the implant neck region is the result of over stress, which is the clinical observation of the formation of alveolar bone around the implant to an inverted cone absorption area consistent. In the functional phase, due to manner and size of load changes, the overall stress level increased, the bone remodeling process of plastic building parts of cancellous bone caused an alarming increase in ossification and cortical bone ossification rates declined sharply. There is no lateral load and lateral load compared to the functional stage of lateral load causes more cortical bone, part of the jaw absorption. 4 Conclusion The results are consistent with clinical observations show that the biomechanical model used to simulate factually implant interface healing process. The bottom of the implant caused by the low stress state of nonunion, and implant neck bone resorption is caused due to excessive stress. Lateral load can cause more bone resorption, which has teeth grinding used cautiously in patients with implants means. 【
