The Reconstruction And Study Of The Postoperative Dental Root Bisection And Dental Implant Joint Cured

In this paper,root bisection and dental implant joint cured patient as the research object.through reverse engineering software to generate the complete model of the mandible and oral tissue with CT scan data.Using the 3D graphics software to intercept and assembly,and obtaining the final model for numerical simulation.Introducing the concept of limit deformation which can form good osseointegration in early loading,making contact relation in friction of mandibular and implant,and applying internal stress and preload.Simulating clinical chew and analyzing whether or not more than150?m.Thus verify the possibility of early treatment,in order to achieve the purpose of shortening the treatment cycle.Applying dynamic and static loads on the postoperative tooth before and after the implant osseointegrates into the bone.Calculating and studying deformation and equivalent stress distribution by finite element analysis.And getting the relationship between the stress,deformation and the bite force through continuous loading calculation.Obtaining the ultimate capacity of postoperative teeth in all directions under the immediate and traditional delayed load.Combined with reliability theory,finite element analysis theory and the function of six sigma analysis,considering the factors of difference of implants' material properties and different groups of people's different bone type and chew.Analyzing the success rate of long-term treatment.Solving the difficulty of large sample size and hard to sampling in traditional surgical.It provided an effective method to predict the success rate of surgery for different bone mass.And obtaining the effect of different factors on the stress of the mandible by calculating the stress sensitivity.In this paper provided a reference for the future researchers to study the optimization of root bisection and dental implant joint surgery.
