What is 3D printing in Dentistry?
3D printing in dentistry refers to the use of additive manufacturing to create custom dental models, appliances, and implants directly from digital scans. The most common process is vat photopolymerization, where liquid resins are cured by light into solid, highly accurate components.
By bringing 3D printing in dentistry into digital workflows, dental professionals can decentralize, customize, and accelerate production, making same-day, in-house restorations and implant components possible.
Applications of 3D printing in dentistry
Photopolymer 3D printing in dentistry has already gone a long way and has led to an improved patient care, reduced chair time, enhanced treatment outcomes and better cost-efficiency for dental practices and academic purposes alike.
3D printing for dental implants
By using 3D printing for dental implants, professionals can create patient-specific implants tailored to the individual's unique anatomy and needs. These are precisely tailored to each patient’s anatomy, ensuring better fit, functionality, and aesthetics. Customized surgical guides further improve implant placement, reducing surgical errors and improving recovery.
Prosthodontics
Prosthodontics is a branch of dentistry focused on the restoration and replacement of damaged or missing teeth and other oral structures. Prosthodontics benefits from 3D printing in dentistry by producing temporary and permanent restorations quickly. Custom dentures, crowns, and bridges fit comfortably, reduce turnaround time, and improve the patient experience.
Orthodontic treatment
3D printing in dentistry allows for the production of custom orthodontic brackets tailored to each patient's tooth anatomy. These brackets can be designed to fit securely and efficiently. As an example, photopolymer 3D printing is widely used to create clear aligners. Orthodontists start by taking digital scans of the patient's teeth, which are then used to design a series of aligners that gradually move the teeth into the desired positions. In this process, the moulds are 3D printed, while the aligners are thermoformed by using plastic films such as polyethylene terephthalate glycol (PETG) or thermoplastic polyurethane (TPU).
Surgical guides
Photopolymer 3D printing has become a game-changer in the production of surgical guides for various dental procedures, including orthodontics, implantology and maxillofacial surgery. Photopolymer 3D printing is ideal for surgical guides because it can achieve high levels of detail and accuracy, which is crucial for successful surgical outcomes.
Surgical guides are essential tools that aid surgeons in performing precise and minimally invasive procedures. During the surgery, the surgical guide is placed over the patient's anatomy and guides the surgeon to make precise incisions, position implants, or perform other procedures. The guide ensures that the surgical actions are carried out exactly as planned, reducing the risk of errors or complications.
Educational purposes
3D printing has opened up new possibilities for dental education and training, allowing dental students and professionals to gain practical experience and improve patient communication. Photopolymer 3D printing allows the creation of highly accurate and detailed anatomical models of teeth, jaws, and oral structures. These physical models provide dental students with hands-on learning opportunities.
3D-printed models can be used for surgical simulations, allowing dental students to practise various dental procedures in a risk-free environment. This includes practising tooth extractions, implant placements and other surgical techniques. Dental schools can even use 3D printing to produce patient-specific models based on real clinical cases. These models serve as teaching tools, allowing students to better explore different treatment options and develop treatment plans for specific patients.
Imaging and reconstruction
Dentists can utilise this technology to create precise models of patients' teeth and jaws based on scans from X-rays or CT scans. These models enable detailed analysis for treatment planning, such as orthodontic adjustments or implant placements. Additionally, 3D printing facilitates the fabrication of custom-made dental implants, crowns, bridges, and dentures.
Advantages of 3D printing in dentistry
Photopolymer 3D printing in dentistry provides numerous benefits, including enhanced customization, greater flexibility, and reduced costs, making this method one of the advantages of 3D printing in dentistry. The following section describes the main advantages of photopolymer 3D printing.
Customization
Customization plays a crucial role in dental care, as every patient has a unique dental anatomy and specific treatment needs. Whether it's dental crowns, bridges, aligners or retainers, the 3D printing process ensures that the appliances fit precisely and comfortably in the patient's mouth. Methods such as stereolithography (SLA) or material jetting use high-resolution printing technologies to achieve intricate details with high precision.
3D printing speeds up manufacturing. It allows for quicker production of custom dental appliances than traditional methods. This reduces the waiting time for patients and leads to streamlined treatment processes as well as ensures patient-centric care
Decentralised manufacturing
Traditional manufacturing often relies on centralised facilities. Here, dental appliances and prosthetics are mass-produced and sent to different clinics. In contrast, photopolymer 3D printing supports a decentralised manufacturing approach.
With 3D printing for dental implants, clinics can print restorations in-house, eliminating reliance on external suppliers. This eliminates the need to rely on external suppliers, reduces lead times and enhances the treatment efficiency. In emergency dental cases, 3D printing enables dental professionals to produce temporary restorations and appliances quickly, providing timely relief to patients.
Material efficiency
Material efficiency refers to minimising waste and optimising the use of resources. Photopolymer 3D printing offers several advantages in terms of material efficiency in dentistry. The reason, among others, lies in the layer-by-layer printing method, which adds material only where it is needed.
This UV additive manufacturing process is inherently more material-efficient compared to traditional manufacturing methods, where excess material is removed to create the final object. Further, with this innovative manufacturing method, there's no need to keep a large inventory of pre-made items, which reduces material stockpiling and waste. Additionally, 3D printing of polymer composites has become increasingly valuable in dentistry, enabling the production of patient-specific crowns, bridges, and prosthodontic models with exceptional precision and efficiency.
Reduced labour costs
As photopolymer 3D printing in dentistry streamlines processes, it simultaneously reduces labour costs for the entire industry. First of all, 3D printing automates the manufacturing process, as the need for manual labour in creating dental appliances and prosthetics can be significantly reduced. Once the 3D printer is set up and the digital design is ready, the printing process requires minimal human intervention.
Having a 3D printer on-site enables dental clinics and laboratories to produce dental appliances and models in-house. This eliminates the need to outsource manufacturing, resulting in cost savings on external production expenses. Therefore, photopolymer 3D printing can lead to significant labour cost reductions and enhanced efficiency for dental practices and laboratories.
Challenges of 3D printing for dental implants
While 3D printing for dental implants offers many benefits, challenges remain: Material limitations:
- Not all materials are suitable for long-term implant use.
