Application of 3D printing in dentistry
With the development of the application of 3D printing technology, the application of 3D printing in stomatology is also continuously improved. The in-depth implementation of such applications can achieve personalized customization and optimize the entire medical process to reduce pain.
Dental dentistry is one of the most promising industries in non-biological 3D printing. The application of 3D printing technology in the oral dental restoration industry mainly includes removable dentures, orthotics and implants. Dental dentistry is currently the most promising Large-scale application of 3D printing technology in the medical industry.
So what are the application directions of 3D printing in the dental industry? Let's introduce Bering 3D to everyone.
1. Planting guide
The traditional dental implant technique only takes X-rays before surgery, and cannot display the three-dimensional structure of the implant area. In this way, the information content expressed by the two-dimensional plane image is limited, and the information obtained by the doctor before the operation is not complete, which often leads to increased intraoperative uncertainties, prolonged operation time, and poor predictability of the effect. The accuracy of the implant repair cannot be guaranteed. Subject to certain restrictions.
With the advent of computer tomography (CT) technology, doctors can rely on CT images to learn more and more comprehensive information about patients before surgery, which is more detailed than traditional two-dimensional plane data. However, in the operation process of implant surgery, it still relies on the experience of the doctor, but no matter how experienced the doctor can only rely on the CT image to accurately transfer the implant position, direction, angle, etc. that were established before the operation to the patient's mouth, making Deviations between the actual implanted position and the expected position are unavoidable, and even more serious may even cause damage to important anatomical structures.
The intelligent 3D printing guide template for dental implant surgery, also known as 3D printed implant surgical guide, referred to as "guide", is a personalized surgical assistant tool that accurately transfers the implant plan that is virtually formulated before surgery to the patient's mouth (Figure 3). It can help clinicians to accurately manipulate the position, direction, angle, and even depth of implant implants during surgery, and assist doctors in implanting implants, so that the final implant repair and the ideal design plan before surgery are unified.
2. Overmolding of crowns and brackets
The use of dental crowns and stent castings in dentistry is also relatively common, but the traditional process usually produces a denture or dental crown must go through the whole process of taking a mold, overmolding, and making. It takes a long time and requires a master Also relatively high. It may be necessary to constantly adjust through the patient's try-on, the whole treatment process is relatively long.
Now through intelligent scanning, combined with the application of 3D printing technology, flip casting and even direct metal printing, it can effectively reduce errors, shorten production time, and avoid manual errors.
3. Application of Orthodontics in Stomatology
Photos and plaster casts during orthodontic correction are the standard for monitoring and recording the entire treatment process. The model can accurately provide the original record of the patient, including the position and size of the teeth. However, there are many difficulties in using the plaster model in clinical work, including the burden of storage, the risk of damage or fracture, and heavy weight. It is also inconvenient Communicate with fellow professionals and patients.
The emergence of a data model based on 3D printing greatly solves these problems. Compared with the plaster model, the data measurement of the data model is also highly accurate.
Using the cost-effective CAD design software of commonly used appliances, 3D printing technology can easily customize all types of appliances, including night-time articulators, retainers, personalized bands, splints, arch expansion, bioregulators, Double plywood, etc.
The appliance can also create a constant amount of offset according to different patients and add ID tags for identification. The customized design is more people-oriented and brings innovative medical experience to patients. In clinical practice, digital models can be obtained through optics, and related software can be used to analyze digital models. This not only solves the discomfort caused to patients by traditional modal sampling methods, but also prints models as needed to facilitate data storage and recall.
