| Abstract: | Objective To establish three-dimension finite element model of mandible with two kinds of Replace implant, and to study stress of implant and abutment. Methods The data of components of the dental implant was measured, cross section of the mandible was scanned by spiral CT and image reconstruction technique was conducted. Threedimension finite element analysis software UG and MSC. Marc/Mentat were used to built the conjunction model and bone model of two implant systems. Axial loading（200 N） and 30° oblique loading（100 N）were applied on the models respectively, the stress distribution patterns of the implant and abutment of two implant systems were analyzed. Results The peak stress district was concentrated on the structure of the implant cervix, which was more obviously displayed on the Replace Select implant. The peak stress of oblique loading was higher than that of axial loading. The peak stress on the implant cervix of Replace Select implant was higher than that of Replace External Hex implant in all loadings. Conclusion To Replace Select especially, oblique force should be avoided on clinical practice in case of the implant fracture. |
