With the development of science and technology, human society has entered the digital age. The perfect combination of digital technology and medicine has formed a new discipline of digital medicine. Dental 3D printer technology is a brand-new manufacturing technology that emerges under this background. Dental 3D printer technology has changed the traditional manufacturing model. It is an important link in the development of digital medicine.

3D printing technology is a kind of rapid prototyping technology, through the reconstruction of the three-dimensional digital model, it is divided into layers and then stacked layer by layer into a solid model. In the field of stomatology, 3D printing technology is gradually applied to various professions with its unique advantages, such as oral and maxillofacial surgery, implantology, prosthetics, oral medicine and orthodontics.

The application of mature 3D printing technology in stomatology:

Oral and Maxillofacial Surgery

The application of 3D printing technology has enabled the development of surgical operations from the traditional purely empirical method to the digital and precise development. Maxillofacial trauma and tumor can cause maxillofacial fractures and bone defects, restore the normal anatomical shape of maxillofacial, maintain good occlusal relationship and language function.

Oral Implantology

The template guides the position of the implant by determining the position of the prosthesis before the operation, so that the prosthesis can restore the patient's good function and beauty. The use of 3D printing technology can analyze the anatomy of the implant area before surgery, accurately capture the position and direction of implantable implants, and make implant guides to transform the designed position of the preoperative implant to the implant area of ​​the surgical patient to ensure the implant The outstanding progress. The implant software can evaluate the bone mass in the implant area, measure the distance from the maxillary sinus and the inferior alveolar nerve tube and other important anatomical structures in detail, and even design the type, size, optimal position and direction of the implant. At the same time, the implant guide is designed according to the above parameters and made with 3D printing technology, which is mainly suitable for patients whose implants need to avoid important anatomical structures, patients who need to obtain a consistent implant angle for multiple implants, and patients who need to complete immediate denture restoration For patients with insufficient bone mass and who do not receive bone grafts, the indications for implant dentures have been increased.

Application of 3D printer in the field of oral cavity

This technology can achieve a three-dimensional design integrating implant surgery planning, restoration design, and surgical guides, greatly improving cost-effectiveness, thereby reducing turnaround time, and opening up new business opportunities for dentists and technicians.

Prosthodontics

Use design software to carry out digital model observation and removable partial denture bracket design and production. Use specific CAD software to achieve 3D printing design of dentures, including tooth base, crown, bridge, dental crown, dental veneer, and dental inlay Wait. The current three-dimensional solutions can already ensure perfect matching, thereby reducing manual intervention and finishing, and realizing efficient, perfect-adhesion denture processing. For complex clinical cases, creating complex inner and outer crown structures can achieve the best effects of space, function and aesthetics.

Oral Medicine

With the development of imaging technology, three-dimensional image reconstruction technology has begun to be applied to the study of root canal morphology. The reconstructed image can observe the root canal morphology from various angles, and conduct comprehensive measurement and analysis to understand and summarize the root canal. The anatomical features and variations of the system. After solidifying the reconstructed model through 3D printing technology, it can also be widely used in oral teaching and clinical preoperative diagnosis and simulated surgery of complex root canals.

Orthodontics

During the orthodontic correction process, photos and plaster models are the gold standard for monitoring and recording the treatment process. The models can accurately provide the patient's original records, including the position and size of the teeth. However, the use of plaster models in clinical work has many problems, including the burden of storage, the risk of damage or breakage, heavy weight, and it is not convenient to communicate with fellow professionals and patients. The emergence of digital models based on 3D printing greatly solves these problems. Compared with plaster models, the data measurement of digital models also has high accuracy.

Using cost-effective CAD design software for common aligners, 3D printing technology can easily customize all types of aligners, including night-use splints, retainers, personalized band rings, occlusal plates, arch expansion, biological adjusters, Double occlusal board and so on. On the appliance, according to different patients, a constant amount of offset can be created, and ID tags can be added for identification. The customized design is more people-oriented, bringing patients an innovative and technological medical experience.

In clinical practice, digital models are obtained optically and analyzed with related software. This not only solves the discomfort caused by traditional model-taking methods to patients, but also prints models as needed to facilitate data storage and recall. Currently, bracketless invisible correction technology is in a rapid development stage, and 3D printing technology also plays an important role in it. Its core technology includes the following three parts: first, three-dimensional reconstruction of the digital model of the dentition; then, using computer-aided diagnosis and design to simulate the movement of the teeth, after confirming the plan, using 3D printing technology to print the simulated dentition model; Finally, the invisible aligner is made using the hot pressing film forming technology.
