Abstract


CDIC ? adjustable taper threaded implant Science and Technology of the Ministry of Health Oral Implantology Center (China DentalImplantology Center Ministry of Public Health, the researchers summarize CDIC) foreign tapered implant clinical success and failure based on the experience, optimize design, combined with surface treatment technology, the introduction of a new type of oral implants. Novel implant has a neck portion of a large diameter, to avoid implant neck is broken by bending; the upper foundation pile is a large-diameter cylindrical morphology and implant integration, can be removed to be able to bring the concentration of stress due to the stress interrupt, at the same time in the mouth directly transferred to the ground to a certain angle. This implant applications front teeth in the mouth area. Animal testing and early clinical applications of the new implant implant has good biocompatibility. This study through computer simulation method used to make a preliminary evaluation of the three-dimensional finite element analysis biomechanical compatibility of the new implant. Human jaw CT data eFilm software Get mandible contour information, and then by Pro / Engineer software to establish the model of the mandible and assembly simulation CDIC ? adjustable taper threaded implant to complete the entire computer modeling process. Model input with professional CAD software interface finite element analysis software ANSYS three-dimensional finite element analysis to simulate the real bite loaded, focus on the analysis of implants and jaw stress distribution. In this study, to discuss two aspects the CDIC ? adjustable taper - screw implant biomechanical compatibility: (a) implant of different implantation length of the implant and jaw stress distribution. (B) of the implant end implanted into the area of ??the cortical bone of the nose at the bottom of the implants and jaw stress distribution. The analysis results show that: the implant to the jawbone, the stress distribution is mainly concentrated in the area of ??the the implant neck lip face and neck cortical bone contact between 312MPa-322MPa, the maximum value of the neck, body cortical bone labial The maximum crest at the top of 59MPa-61MPa Implants - osseointegration interface, the rapid decay of stress to the the implant root of direction from the alveolar crest, implant maximum stress value is less than the fatigue strength of the material. The study found that implants of different implantation length distribution has little effect on the stress of the whole structure. When the implant end implanted into the cortical bone area of ??the nose at the bottom, the maximum value of the stress of the implant neck about 300MPa maximum value of about 49 MPa in the cortical bone implant apical greater stress distribution. Studies have shown that such cultivation physical effectively reduce the stress of the implant neck and crestal cortical bone, so that the entire structure of the stress distribution tends to uniform, is conducive to the integration of the implant and mandible. This study can prove, CDIC ? adjustable taper threaded implant has good biomechanics
