Have you actually looked back at your long-term cases to see how layering compares to injection moulding?
Is traditional freehand layering still your go-to for anterior composite aesthetics?
Are you using it because it gives the best result — or just because that’s how you were trained?
In this episode, Dr. Marco Maiolino joins Jaz Gulati for a meaty discussion about injection moulding—a technique that’s changing the game in anterior composites (and posterior!)
This isn’t about trends. It’s about clinical outcomes.
We’ve all admired the beauty of layered composites—translucency, halo, the “natural” look. But after 5, 7, or even 10 years… do they hold up?
Dr. Maiolino brings over a decade of follow-up data—and the results might surprise you.
Protrusive Dental Pearl
- When in doubt between two shades (e.g., A1 vs. A2), always choose the lighter shade. Higher-value shades blend better and result in higher patient satisfaction.
- Techniques: Use the composite button method and black-and-white photography to objectively evaluate shade blending.
- Outcome: Lighter shades minimize the risk of patient dissatisfaction and rework.

Key Clinical Takeaways
- Injected composites often outperform layered ones in long-term follow-up.
- Color stability is as much about technique as it is about material selection.
- Edge bonding requires careful occlusal planning and respect for functional dynamics.
- The biologic cost of veneers is frequently underestimated—additive approaches can be more conservative.
- Composite thickness and occlusal harmony are critical for restoration longevity.
- Rigorous documentation and honest case review matter more than dramatic presentations.
- Failures are not setbacks—they are opportunities for professional growth and better patient care.

As clinicians, we’re constantly challenged to balance esthetics, function, and longevity in our restorative work. In this episode, Dr. Marco Maiolino joins Jaz Gulati for a candid, evidence-driven exploration of injection moulding—a technique that’s rapidly shifting the paradigm in anterior composite restorations. This isn’t about chasing trends; it’s about critically evaluating what truly works for our patients over the long haul.
Dentists will be able to:
1. Understand the indications, benefits, and limitations of edge bonding and injection moulding.
2. Recognize how minimally invasive dentistry can provide reversible, conservative treatment options.
3. Appreciate the importance of proper planning and case selection when using techniques like injection moulding.
