Abstract


Similarity with orthodontic problems, makes the study of frames a very important problem, with practical applications in life domains, in the field of health, especially in dentistry. This work presents an analytical calculus for a frame, using the Transfer-Matrix Method (TMM). The frame has two vertical poles, embedded at inferior ends and with a vertical concentrated load, in the middle of horizontal part of frame. The two pole teeth can be assimilated with the two vertical parts of frame and the aggregation elements, together with the bridge body, can be assimilated with the horizontal part of frame. We can determine the displacements aggregation elements. The results will allow, in practice construction of dental bridges to ensure the best resistance. We can solve this problem very easy on an appropriate soft.
