| Abstract: | Objective To analyze the stress distribution of bone around the dental implants with lateral immediate loading of different angles by three dimensional finite element.Methods An adult edentulous mandible was adopted for CT scanning.The CT image was imported to universal surgical integration system to establish a mandible three dimensional mesh model.The real shape of standard thread implant was simulated and the finite element model of mandible with dental implants for immediate loading was established.The ... |
