The 3D printing technologies have the advantages of high material utilization and the ability to manufacture a single complex geometry nevertheless, they have the disadvantages of high cost and time-consuming postprocessing. The final section presents a summary of the clinical applications of 3D printing in dentistry, including manufacturing working models and main applications in the fields of prosthodontics, oral and maxillofacial surgery, and oral implantology. Additionally, it introduces various factors affecting 3D printing metrics, such as mechanical properties and accuracy. First, it introduces current 3D printing technologies, including powder bed fusion, photopolymerization molding, and fused deposition modeling. This review provides a practical and scientific overview of 3D printing technologies. Three-dimensional printing has many advantages in process engineering, with applications in dentistry ranging from the field of prosthodontics, oral and maxillofacial surgery, and oral implantology to orthodontics, endodontics, and periodontology.

They have been widely used in the industry, design, engineering, and manufacturing fields for nearly 30 years. Three-dimensional (3D) printing technologies are advanced manufacturing technologies based on computer-aided design digital models to create personalized 3D objects automatically.
