Research Progress on the Preparation Process and Material Structure of 3D-Printed Dental Implants and Their Clinical Applications

Abstract

Additive manufacturing, commonly known as 3D printing technology, has become a prominent topic of research globally in recent years and is playing an increasingly important role in various industries. Particularly within the healthcare sector, the use of 3D printing technology is gaining prominence, with a special focus on the manufacturing and application of dental implants. As research in this field progresses, the preparation methods, material selection, and technological innovations for dental implants are evolving, promising a future where the manufacturing process of dental implants becomes even more refined and efficient. Through thorough research in materials science, it is possible to develop dental implant materials that have better biocompatibility with the human body and improved mechanical properties. Additionally, advancements in surface modification technology can further enhance the strength and stability of the bond between dental implants and bone tissue. These advancements not only expand treatment options for patients but also greatly improve the long-term success rate of dental implants. In the field of dental implants, the success of the implant depends on the interactions between the materials used, the cells involved, and the bone tissue. Therefore, there is an urgent need to explore the molecular mechanisms of such interactions in depth. In this study, we provide a comprehensive review of the application of 3D printing technology in the fabrication of dental implants. This includes an examination of the process methods, surface coating technology, and a comparison of the shapes and structures of different dental implants, along with their advantages and disadvantages. Furthermore, this paper analyzes the intrinsic mechanisms of successful dental implant placement in clinical practice, and it highlights the latest progress in the clinical application of 3D-printed dental implants. Undeniably, the use of 3D-printed dental implants not only offers patients more precise and personalized treatment plans but also brings revolutionary changes to the development of the medical industry.
