Deep margins and limited access are our daily challenges 😮‍💨🦷
When wedging doesn’t work, the mylar matrix + Teflon combo truly saves the case: tight contact, clean margins, less stress 🙌

But these situations demand precise technique — otherwise marginal gaps will keep coming back.

🔥 In the course “Contact Point: Effective Techniques for Posterior Tooth Restoration” you’ll find clear, practical methods that make complex restorations truly predictable.
💻 Intraoral scanning under isolation is a powerful tool, but the outcome depends entirely on proper technique.
The images clearly show how the same area can look with correct vs. incorrect scanning.

❗ Common mistakes include:
— insufficient soft-tissue retraction → lost margins;
— incorrect lighting/mirror positioning → noise and artifacts;
— missing data on deep preparation edges;
— chaotic scanning path → reduced STL accuracy;
— poor moisture control → reflections and distortions.

Each detail affects restoration adaptation and often leads to remakes.

💡 The solution is a precise, repeatable protocol.

And that’s exactly what you’ll get in the course:

These are the kinds of cases you’ll never see on a congress stage…
But they’re exactly the ones that show up in the clinic and drain you the most 😅🦷

Case: an old crown on 15 → mesial caries on 16, below the CEJ, subgingival, minimal interproximal space, and isolation done “on inspiration” 😬

Steps:
🔹 Fibrotomy to open the sulcus for matrix placement
🔹 Mylar matrices placed into the sulcus — self-sealing effect
🔹 Teflon to adapt to the cervical concavity
🔹 Delayed separation → first margin with flowable
🔹 Injection molding
🔹 Overmolding to bring margins into accessible, finishable areas

Not perfect — but these are exactly the cases that teach us the most 💪✨

🤩 In the course “Contact Point: Effective Techniques for Posterior Tooth Restoration” you’ll learn techniques that help you manage such “resistant” cases with confidence and predictability.

Let complex cases become your strong point 😉🦷💙

🌿 How to Preserve Tooth Structure and Keep the Child Comfortable

The radiograph shows a tight contact that makes caries management more challenging 🥲. In such cases, a simple orthodontic separator is an excellent tool to gently create the necessary space without traumatizing the tissues and while preserving as much healthy tooth structure as possible.👌🏻

✔️ Fast ⚡
✔️ Painless 😊
✔️ And highly conservative toward healthy tissues 🌿

Modern pediatric dentistry is not about “fixing at any cost.” It’s about choosing the right technique, respecting anatomy, and ensuring the child’s comfort throughout treatment.

✅ These thoughtful, minimally invasive protocols are exactly what is taught in the Pediatric Dentistry School course — where every step is grounded in evidence-based practice and real clinical experience. 📚💡
