Abstract:

BACKGROUND: In recent years, rapid prototyping has provided new options for the manufacture of customized titanium implants.
OBJECTIVE: To review the optimization of titanium bone implants made by rapid prototyping, and assess its clinical value.
METHODS: A computer-based retrieval of PubMed database and CNKI was performed for relevant articles by using the keywords of “rapid prototype, 3D printing, additive manufacture, titanium, custom-made, implant” both in English and Chinese. These articles were analyzed from two aspects: the performance optimization and the clinical application of titanium bone implants produced by rapid prototyping.
RESULTS AND CONCLUSION: Rapid prototyping technology enables the production of customized bone implants, and biological properties of the implants can be varied through the introduction of porosity and Morphological changes of the implant. In combination with surface treatment technology, such as coating technique, the biological performance of the implants can be further optimized. Therefore, the rapid prototyping technology can be used to create customized titanium bone implants with excellent mechanical and biological properties. The titanium bone implants made by rapid prototyping have great prospect in the clinical practice.
