introduction

introduction

Dentistry has undergone a remarkable transformation with the advent of 3D printing
technology. Gone are the days when patients had to endure multiple visits for restorative procedures. With cutting-edge 3D printing solutions, dental professionals can now offer patients a more efficient and convenient experience.
This article explores the use of 3D printing technology to create inlays, onlays and overlays in a single visit, revolutionising how we approach dental restorations.

the patient's dilemma

the patient's dilemma

Imagine a patient walking into a dental office, seeking to replace old fillings and repair
cavities (Fig. 1).
Traditionally, such restorations would require several appointments, numerous impressions and temporary restorations before the final one was ready.
This process was not only time-consuming but also frustrating for the patient.
However, with innovative 3D printing capabilities, this patient’s experience
can be drastically improved.

A good range of 3D printers are specifically designed for dental applications, including from SprintRay.
These printers use advanced materials and high-resolution printing technology, enabling dental professionals to craft precise and durable dental restorations in a fraction of the time of traditional methods.

CREATING HYBRID RESTORATIONS IN ONE VISIT

CREATING HYBRID RESTORATIONS IN ONE VISIT

With the help of SprintRay’s 3D printers and their unique crown kit, dental professionals can now create inlays, onlays and overlays using the latest hybrid resin materials (SprintRay Crown) in a single visit. The process is relatively straightforward and time-efficient, sparing patients the inconvenience of multiple appointments.

How it works:

1. Digital scanning

The patient’s teeth are digitally scanned using an intraoral scanner (Medit i700 Wireless). This 3D scan creates a highly accurate virtual model of the patient’s dentition, eliminating the need for messy traditional impressions (Fig. 2).

2. CAD design

The virtual model is imported into computer-aided design (Medit ClinicCAD) software, where the dental professional custom designs the inlay, onlay or overlay to precisely fit the patient’s tooth (Figs 3, 4).

3. 3D printing

Once the design iscomplete, the digital file is sent to the SprintRay Pro 95S 3D printer (Fig. 5). Using the chosen hybrid resin material (SprintRay Crown), the printer begins the additive manufacturing process, layer by layer, until the restoration is complete (Figs 6, 7).

4. After approximately 20 minutes of printing, thanks to the crown kit that speeds up the process, the dental professional carefully removes the restoration from the printer (Figs . 8, 9). The printed restorations are then placed in the SprintRay wash and dry unit, where they undergo thorough washing with isopropyl alcohol to remove any excess resin and ensure optimal cleanliness (Fig. 10).

5. The dental professional makes any necessary final adjustments and polishing to guarantee a perfect fit and natural appearance of the restoration (Figs 11, 12). Once the adjustments are complete, the restorations are transferred to the SprintRay Pro-Cure2 unit for the final curing process.

6. The ProCure2 unit uses advanced light-curing technology to polymerise
the resin fully, enhancing the strength and durability of the restoration. This step is crucial in ensuring that the restorations are ready for immediate use once they are taken out of the curing unit (Fig. 13). 

7. With the printing, washing, curing and cementation processes completed in a single visit, the patient can walk out of the dental office with their new, fully functional and aesthetically pleasing restoration, thanks to the remarkable capabilities of SprintRay’s 3D printing technology. The restorations are securely bonded in place using G-CEM ONE universal self-adhesive resin cement with dual-cure ability, designed to provide strong and durable bonding of indirect restorations. This ensures a long-lasting and reliable outcome for the patient’s dental health and satisfaction (Fig. 14).

The integration of SprintRay’s 3D printing technology in dental practices offers numerous benefits.

  • Time-efficient: Patients can have their restorations completed in a single visit, saving them valuable time and reducing the number of appointments required.
  • Enhanced precision: 3D printing ensures a high level of accuracy and a perfect fit for each patient’s unique dental anatomy, leading to improved longevity and functionality of the restoration.
  • Improved aesthetics: The hybrid materials used in 3D printing closely mimic the appearance of natural teeth, providing patients with aesthetically pleasing and discreet restorations.
  • Streamlined workflow: Dental professionals can optimise their workflow, reducing chair time and increasing patient throughput, ultimately benefiting both the practice and the patients.

conclusion

3D printing technology has revolutionised the field of dentistry, offering patients a streamlined and efficient experience when it comes to restorative dental procedures. By using innovative solutions, such as SprintRay’s crown workflow, dental professionals can now provide high-quality, precise and aesthetically pleasing inlays, onlays and overlays in a single visit, bringing a new era of convenience and excellence to dental restorations.

Traditional silicone-key direct composite restorations suffer from variable thickness, internal voids, imprecise trimming and high labor cost. Pressed composite integrates facially-guided Digital Smile Design, dual-step 3D-printed IBT-Flex guides, and a volumetric “PRESS” dispenser filled with high-fill composite. In a two-visit restorative session following clear-aligner therapy and guided crown lengthening, this workflow achieved exact replication of the planned anatomy, texture, form, and function. The 18-month follow-up findings show stable margins, minimal wear and high patient satisfaction.

Digital dentistry has transformed restorative and esthetic treatments. Technologies such as intraoral scanning, digital smile design, and chairside manufacturing enable clinicians to deliver precise, minimally invasive, and efficient care.

Digital dentistry has undergone rapid developments and changed the contemporary approach to patient treatment in many ways. New chairside digital workflow protocols, for example, enable dental practitioners to simplify previously multistep laboratory procedures, reducing treatment time and lowering the cost of the process. Chairside protocols enable clinicians to perform restorations in a single office visit, providing patients with a more comfortable and efficient experience.
