Dr Kiran Shankla presents a case study demonstrating the benefits of Stela, a self-cure composite that streamlines restorative dentistry while delivering durable, aesthetic results.
A 17-year-old female patient presented for a routine six-month examination without complaints or concerns regarding her teeth. I noted a small colour change on the upper left premolar during the examination with five times magnification loupes. An X-ray confirmed the presence of a cavity, which was highlighted using a second-opinion AI software. Given the cavity’s location in the visible smile line and the patient’s age, I opted for a tooth-coloured filling rather than the NHS amalgam option. Stela, a high-performance self-cure composite, was selected for its aesthetic and functional qualities.
Treatment details
The patient was booked for the filling appointment, where I administered a local anaesthetic. As this was her first filling, the aim was to ensure a pleasant experience. I prefer working under a rubber dam for better control during the procedure, although Stela does not require one. After removing the decay, I took several photos to help illustrate the cavity’s extent. I then placed a sectional matrix to ensure proper contact closure, as the cavity was large. After this, I applied Stela.
Stela’s two-step system consists of a primer and composite, significantly reducing the steps typically required for an amalgam restoration. The primer, which takes just 15 seconds, was followed by applying the Stela composite. This material’s consistency allowed me to sculpt it before it was set, making the procedure more efficient.

Outcome and follow-up
The restoration process was straightforward, efficient, and completed in less time than traditional methods. The use of Stela reduced the number of instruments and procedural steps involved, making the process more cost-effective and time-efficient. After placing the filling, I let the material set for a few minutes, then carried out final trimming and polishing without additional curing lights, simplifying the procedure even further.
After treatment, the patient reported no sensitivity, and the restoration remained intact with no complications. However, as she is considered at higher risk for dental issues, I will schedule an X-ray in one year to assess the restoration’s longevity.
Why Stela was chosen
I selected Stela for its excellent aesthetic qualities, fast-setting process, and ability to provide durable, reliable results. The material’s natural translucency allowed it to blend seamlessly with the surrounding tooth structure, a crucial factor due to the cavity’s location. Furthermore, Stela’s superior mechanical properties, including high flexural and compressive strength, made it an ideal choice for a restoration designed to withstand everyday function.
Stela has significantly improved my workflow, replacing the traditional multi-step amalgam process with a simplified two-step system. This approach saves me time and reduces the risk of technique errors. The self-curing nature of Stela eliminates the need for light curing, enhancing productivity, especially in busy NHS practices.
Stela’s gap-free curing properties reduce the risk of shrinkage and microleakage, contributing to more reliable, long-lasting restorations. The material’s self-curing properties allow it to cure from the margins inward, effectively reducing polymerisation stresses common in light-cured composites.

Patient satisfaction
The faster treatment time and less invasive procedure enhanced the patient’s experience. Stela’s simple, two-step process and reduced chair time made the procedure more comfortable.
Stela offers a transformative approach to restorative dentistry by simplifying procedures and improving clinical outcomes. Its self-curing properties, durability, and aesthetic appeal make it a strong alternative to traditional amalgam, reducing treatment time and enhancing productivity. This case highlights how Stela can streamline restorative dentistry, providing high-quality, durable, and aesthetically pleasing results with minimal effort.
