Research On Series Model Of Double Roots-analogue Dental Implant

Because of the disadvantages of traditional teeth restoration methods in esthetics and function,more and more people prefer to choose implanting restoration as their prime way to restore their teeth.The implants should have good biocompatibility into the jaw bone.Most of molars have multiple-roots.Chewing is a very complex dynamic process and molars afford the largest of the bite force,not only to afford the vertical load,but also to afford lateral load.Replacing the implantation of moral with the single-root implant can’t simulate the force transmission of the natural molars and stress distribution characteristic of tooth roots.It also has large defects in anti-rotation.Although there are already many researches have been taken about the bio-adaptable dental implant.But because of its complex design and manufacturing process and its narrow adaptive,it is difficult for commercial promotion.The article based on bionics,proposes the restorative method with double-roots analogue dental implant.It combines experiment and the finite element method to study the effect of double-roots analogue dental implant,and analyzes its mechanical properties,to provide reference for the new type of implant for moral implanting.The main works and results of this paper are as follows:(1)The article detennine the double-roots analogue dental implant geometric parameters matching to the morals with statistical analyzing of large number of adult morals.Then using computer aided design(CAD)technology to design the double-roots analogue dental implant which is appropriate for mass production and easy to prepare hole operation.(2)Design and build the experimental platform.It uses electrical measuring experiment to explore the mechanical properties of double roots-analogue dental implant under impact load.It proves that the double roots-analogue implant has better stress relief performance.And the experiment results provides the reference for the finite element simulation,to verify the reliability of the results of finite element method,laying the groundwork for further research.(3)Also this paper use finite element method(FEM)to explore the stress distribution of double roots-analogue implant in the jaw under impact load,and compare with the stress distribution of the single root implant and evaluated the mechanical properties of the double roots-analogue implant.(4)Finally we have comprehensive evaluation on mechanical properties of the double roots-analogue implant.Through experiments and finite element method,we found the double roots-analogue implant has better stress relief and anti-rotation performance for different bone conditions and different loads.It can be a new type of implant for moral implanting in the coming future.
