Now there are actually only three kinds of imported prosthesis, one is Mantle, the United States; Magee, also of the United States, and now the German Pauli. These three types of imported prostheses are not particularly different in nature, are better a prosthesis. At present, the clinical use is more Mantoux prosthesis, the use of more, Magee use longer, but Magee complications are relatively higher than Mantoux. The difference lies in the softness, realism and dynamics, as well as complications, relatively speaking, Manto may be less, each has its advantages and disadvantages, but are very good imported prosthesis, and no impact on the health of the body, is a very safe prosthesis. At present, the majority of imported prostheses in the clinical use of these two. Now there is another kind of prosthesis is the German Pauli, is also very good prosthesis.
