Abstract

The invention belongs to the field of dental materials, and specifically provides a method for modifying a pure titanium dental prosthesis through solid carburization. The method is characterized in that a solid carburization method is carried out, and a TiC film is formed on the surface of the pure titanium dental prosthesis, so that the hardness of the pure titanium dental prosthesis can be improved, and the abrasion resistance can be also greatly improved; in addition, the TiC film has the anticoagulation unction, so that the modified pure titanium denture also has a certain biological activity. According to the method, the solid carburization can meet the requirement of obviously improving the performances of a medical pure titanium surface, and moreover, the cost is low.

Description

technical field [0001] The invention belongs to the field of dental materials, in particular to a method for modifying a pure titanium denture prosthesis by solid carburizing. Background technique [0002] Due to the excellent performance of pure titanium as a biomedical material, it has been widely used in orthopedics, surgery and other medical fields with good results. Compared with titanium-based alloys such as Ti6Al4V, pure titanium has better biomechanical compatibility with human tissues, and is less likely to cause stress concentration and poor bone resorption of bone tissue around the restoration caused by mismatching elastic modulus. In terms of material selection, pure titanium such as TA4 is more widely used, and is more suitable for denture restoration under osteoporotic conditions. However, there are many problems in the use of pure titanium, especially the obvious lack of surface wear resistance and hardness. After being used for denture restoration, problems...
