Definitions
- WO 01/14601 A1 a method is presented for manufacturing medical or dental instruments through a series of process steps including precipitation hardening, tempering, quenching and hardening, the result of which is a homogenous hardness of at least 450 HV.
- osteosynthesis products are often used to join bones following fractures or following operative sawing of the bones, i.e. they are implanted. These implants then normally remain until complete healing of the bone and furthermore inside the body of the patient.
- Known osteosynthesis products available on the market are manufactured from so-called stainless steel, such as the abovementioned steel grades. Since for such osteosynthesis products, in addition to the mechanical and corrosion properties, high demands on the biocompatibility are made, there is only a limited choice of materials available for the manufacture of these products (not all the materials shown in Table 1 below meet this condition). It has been found that the fracture resistance of the known implants, in particular after long periods of indwelling, is poor.
- inventively manufactured tools and osteosynthesis products combine hardness, high corrosion resistance, good biocompatibility and exceptional fracture resistance in the manufactured products. Even when bent the products remain secure against fracture and can, as for example in implants for plastic surgery, be bent a number of times, without losing their exceptional material properties. Furthermore, the inventively used steel grades are easy to machine and easy to mill in the hardened state, which is of benefit in the manufacture of the products. A further advantage of the application of the inventively used steel for the manufacture of implants and osteosynthesis products for application and remaining in or on the human body is the relatively low hardening temperature in the region of 425 to 525° C. allowing considerable energy cost savings during manufacture.
