Abstract:
Objective:To study the stress distribution in bone with different densities around dental implants in different shape.Methods:Dental implants in the shape of cylinder,thread and steps were implanted into the mandibular bone at the position of the first molar with 4 different densities respectively.Three-dimension finite element models were rebuilt and stress distribution in the bone around implants were investigated. Results:In the same load and bone density conditions, cylindrical implant resulted in lowest peak stress value,the same implant in mandibular bone with higher density produced lower stress peak value.Conclusion:Dental implatns in the shape of cylinder and higher density of the bone around the implant may reduce stress concentration.
