Abstract:

BACKGROUND: The emergence of multi-slice spiral CT and post-processing techniques can establish the standardized values for the simulation and measuring of the surgical site and the surgical area before dental implant surgery.
OBJECTIVE: To evaluate the research and clinical value of spiral CT-based finite element analysis in implant dentistry.
METHODS: A computer-based retrieval was performed for the related articles with the key words of “CT, finite element, dental implants, stress analysis” in Chinese and English from January 2002 to January 2012. The related articles of the dental implant finite element analysis were included; the repeatitive studies or Meta-analysis articles were excluded. The research and application of finite element analysis in implant dentistry were discussed focused in 7 articles.
RESULTS AND CONCLUSION: The finite element analysis of jaw DICM image spiral CT acquisition image was performed after modeling, which provides more comprehensive and reliable image data for the operation, and the clinical dentists can design the surgery program based on the finite element model in order to measure the data required in the surgery, simulate the surgical process and reduce the pain of the patients. Reasonable combination of biomechanics researches of the CT image and the digitized modeling establishing and finite element analysis, and the analysis of the relationship between dental implant position and the surrounding structures, can provide allround image data and mechanical analysis basis for the clinical dentists.
