The world of denture manufacturing has leapt from using ivory and porcelain to employing advanced materials like Lucitone. This cutting-edge material is central to modern 3D printed dentures, offering remarkable enhancements in performance and durability.
Key Characteristics of Lucitone:
-
Strength
Lucitone is classified as a Body Activated Material (BAM). While still as robust as traditional denture materials in ambient conditions, it doubles in strength when in use. This innovation ensures the dentures handle the stresses of daily use effectively. Lucitone Digital IPN showcases minimal volume loss—just 0.005 cubic inches (0.09 mm³)—making it exceptionally durable over time.
-
Water Resistance
Boasting 4.3 times the water resistance of competitors like Flexcera™ Smile, Lucitone resists degradation and warping. Such impermeability helps safeguard against bacteria growth, which can compromise typical dentures.
-
Dimensional Accuracy
Precision is fundamental in 3D printed dentures. Remarkably, 90% of the denture base's fit surface is accurately created within 0.005 inches (0.13 mm) of the design blueprint. This precision guarantees a snug fit, enhancing both comfort and appearance. The same accuracy extends to the tooth resins, where 95% of the tooth surface aligns within 0.005 inches (0.13 mm) of the designed specifications.
-
Tooth Bonding and Stability
The stability of both the base and the teeth in a denture is crucial to prevent the frequent issue of debonding. Through using Lucitone for both components, these dentures achieve exceptional bonding strength, ensuring longevity and reliability.
-
Colour Fidelity
Lucitone Digital IPN 3D Premium Tooth Resin offers an impressive array of 18 shades, enabling dentists to match the patient's natural teeth closely. Importantly, these shades remain stable over time, keeping the dentures' appearance consistent. Proper care ensures that the dentures maintain their natural aesthetic for years.
This advanced material not only elevates the performance of dentures but also ensures that they meet the modern-day demands of both dentists and patients. With these innovations, 3D printed dentures are not just functional but are also a reliable and aesthetic prosthetic solution.
Workflow for Crafting 3D Printed Prostheses
There’s undeniable innovation in the digitalised process of creating 3D printed dentures. Unlike traditional methods which can involve multiple visits, modern technology often reduces this to a two-step appointment process.
First Appointment – Digital Scanning
The journey begins with a digital scan using an intraoral scanner (IOS). This scanner rapidly captures accurate images of the patient’s dental structures and any special clinical observations or photos are shared with the technologists in the laboratory. The ease and efficiency mean that, remarkably, half of this procedure is completed almost immediately.
Behind the Scenes – Denture Fabrication
Once the scans and data are sent, the fabrication magic commences. Technicians employ sophisticated computer-aided design (CAD) and computer-aided manufacturing (CAM) software to craft a precise digital model. This software allows for precise adjustments to patient case parameters (articulation, lateral excursion, incisal height etc) ensuring all data is correct before printing starts.
The prescribed design is then loaded into a 3D printer, a highly technical process where materials such as Lucitone are extruded layer by layer. This method guarantees structural integrity while reducing manual inaccuracies. Once printing is complete, the denture is removed from the raft, which serves as its foundation during creation. Technicians then refine its edges and check the denture’s quality and consistency in colour.
Second Appointment – Fitting the Denture
After about a week, the patient returns to test their new denture for comfort and fit. This fitting appointment is critical for ensuring the patient is satisfied with the end result. If adjustments are necessary, they are usually minor, showcasing the precision of the prior digital work.
Special Cases – An Extra Step for Fully Edentulous Patients
For patients without any existing teeth, an additional appointment is sometimes required to recreate the bite accurately. Initial arch scans take place during the first visit, and a wax rim is crafted to aid in bite registration during the second appointment. The combined scans produce a complete dental model for the final denture fabrication.
Advantages of the 3D Printed Denture Process
The adoption of 3D printing in denture production holds numerous benefits. The process not only shortens dentist chairside time and hastens delivery but also alleviates complex shipping logistics. A digital record of every step ensures reliable record-keeping which aids in reducing both the chances of needing adjustments and the occurrence of remakes. This method simplifies the replacement process in case of future damage or loss.
Moreover, the reduced appointment frequency improves patient satisfaction, offering a seamless and impressive dental solution. For those contemplating a switch, the technological prowess certainly adds a ‘wow’ factor to the patient’s experience. Whether it’s better clinical outcomes or bolstered efficiency, the 3D printing workflow exemplifies how modern dental practices are moving into the digital age.
Benefits of 3D Denture Production
The world of denture manufacturing has been significantly transformed with the arrival of 3D printing technology. This innovative approach offers numerous advantages over traditional denture creation methods, enhancing the overall patient and practitioner experience.
Enhanced Durability
3D printed dentures, particularly those made with Lucitone material, possess remarkable strength. The flexural strength, which is approximately 19,580 psi (135 MPa), and compressive strength, measuring around 20,590 psi (142 MPa), result in dentures that can withstand everyday wear and tear more effectively than their conventional counterparts. This increased durability reduces the frequency of repairs and replacements, providing a long-lasting solution for patients.
Precision and Consistency
One of the major strengths of 3D denture printing lies in its ability to deliver a precise fit. Utilising digital scans securely stored in a database ensures that if a denture is lost or damaged, an exact replica can be fabricated using the same digital data. This consistency reduces the need for multiple adjustments, which are often necessary with traditional dentures to achieve a satisfactory fit.
Improved Efficiency
The production process of 3D printed dentures is efficient and minimal in terms of waste and time. Automated production allows dental technicians to handle a larger number of orders, significantly cutting down the time required to create each prosthetic. Less manual labour and reduced material waste help in lowering the costs often associated with traditional denture-making methods. Patients can typically expect to receive their 3D printed dentures in about a week, offering a quicker turnaround than traditional methods.
Did you know? Traditional denture fabrication can involve multiple appointments for fittings and adjustments, but 3D technology can condense this process substantially. For example, practices using 3D printing techniques often report a reduction in necessary appointments from seven to just two.
Strength and Repair Benefits
In traditional dentures, repairs frequently stem from tooth detachment issues. However, with printed dentures, where the substructure forms a unified piece, the risk of individual teeth becoming dislodged is virtually eliminated. This design improvement leads to fewer repair needs, benefiting both dentists and patients by reducing inconvenience and additional costs.
Dr. Robert Lee, an experienced dentist, highlights that the precision of digital dentures ensures a secure fit, reducing discomfort and the number of sore spots typically associated with traditional dentures. This results in a more streamlined workflow and greater capacity for patient care, enabling practitioners to handle a higher volume of cases efficiently.
Workflow and Economic Efficiency
3D printing also transforms the economic aspect of dental practices. By minimising the number of appointments needed to perfect a denture fit, dentists can see more patients in the same timeframe. This optimises resource use and contributes to economic efficiency. For example, some practices have increased their capacity to 30-50 full denture cases per month thanks to the streamlined processes enabled by 3D technology.
