Applications of 3D-Printing Technology in Dentistry

Abstract

3D printing has been acclaimed as a disruptive technology which will change manufacturing. The technology has a particular resonance with dentistry. It

has become of great importance with advancement in 3D imaging and modelling technologies such as CBCT, intraoral scanning and CAD CAM in dentistry. Advancement of technology in dentistry have improved the diagnostic accuracy, eased treatment delivery and reduced chair time allowing the dentist to provide more effective treatment.3D Printing allows the dentist to visualise, record hard and soft tissue significantly with precise measurement and print the models.

Uses of 3D printing include the production of drill guides for dental implants, the production of physical models for prosthodontics, orthodontics and surgery, the manufacture of dental, craniomaxillofacial and orthopedic implants and the fabrication of copings and frameworks for implant and dental restorations.

Multiple 3D printing methods such as Stereolithography  ,Inkjet based system, Selective laser sintering  , and Fused deposition modelling   allows us rapid prototyping. Each technology offers specific advantages in the creation of particular type of products. In the dental field SLA and Inkjet based systems are

most commonly used. This review examines the current applications of 3D printing within dentistry, including the fabrication of dental prosthetics, orthodontic devices, and surgical guides. It highlights the benefits of rapid prototyping, customization, and precision that 3D printing offers, thereby improving treatment efficiency and efficacy. Additionally, the review discusses the materials used in 3D printing, technological advancements, and challenges faced by practitioners, such as regulatory compliance and material limitations. Future directions for research and development in 3D printing technology are also explored, emphasizing its potential to further transform dental care practices and optimize patient-centered solutions.
