砄bjecat:To study the correlatiom between stress and structure of one piece spiral implant.Methods: The morphology of alveolar bone was selected by CT around the first molar of mandible and around the incisor of maxilla of a healthy man in the position of normal occlusion. Cortical bone with the thickness of 1～2 mm was used to make the alveolar bone model. The one piece spiral implants with root, in the shape of cylinder, length of 10,12, 13 and 14 mm, corona height of 4 and 9 mm,diameter of 3.6,3.7, 3.8,3.9 and 4.0 mm were prepared respectively. The implants were put into the alveolar bone models and a load of 200 N was applied vertically, or 45 ℃ obliquely or 45℃ non center obliquely. The stress on the implants was measured and studied with 3D FEM. Results:The stress on the implants was inversely correlated to the length and diameter in the place of front teeth and molars except non centeraly obliquely loading to molar. The greatest stress was found around the neck of the implants. The distribution and intensity of the stress were related to the way of loading and the elastic modulus of bone. Conclusion:The length and diameter of one piece implant are the factors correlated to the stress on the implant and surrounding bone.
