Unlocking the Secrets of Seamless Diastema Closure Restorations

Whether you’re tackling your first diastema closure or looking to refine your technique, this on-demand course is your ticket to mastering this critical skill in restorative dentistry.
Dr. Dennis Hartlieb
I’m thrilled to share that we’ll soon be launching an all-new course from Dental Online Training: Diastema Closure with Freehand Composite Bonding. This isn’t just a course about closing gaps—it’s about mastering the art of creating seamless, natural-looking restorations that truly transform smiles.

As restorative dentists, mastering composite resin is absolutely essential for success. Yet, one of the most deceptively challenging techniques we face is the diastema closure.

On the surface, it might seem straightforward, but achieving a flawless restoration that blends perfectly with the natural tooth structure while maintaining periodontal health, requires an intricate understanding of materials, contours, and techniques.

Why Diastema Closure Matters

Diastemas come in all shapes and sizes, from minor gaps to larger spaces caused by tooth fractures or malformed teeth like peg laterals.

Regardless of the case, our goal as dentists is always the same: to deliver restorations that look and feel natural, with smooth contours from subgingival margins to the facial and palatal surfaces.

In this course, I’ll walk you through the techniques needed to tackle a variety of diastema cases, including:

  • Small gaps that require subtle enhancements.
  • Larger diastemas that demand careful attention to contours and material application.
  • Complex cases, such as peg lateral incisors, where space management and overall smile design are crucial.

The Art of Seamless Restorations

Creating a seamless restoration is more than just closing a space—it’s about making it look like the gap was never there.

We’ll explore the step-by-step process to ensure your restorations blend effortlessly with the surrounding tooth structure, creating a harmonious, natural smile.

Here are some of the questions we’ll answer in the course:

  • How do you ensure composite resin matches the natural tooth structure?
  • What materials work best for different types of diastema cases?
  • How do you manage contours and transitions to avoid telltale signs of restoration?
  • Do you need to prep teeth to close spaces?

A Spotlight on Complex Cases

One of the standout cases we’ll cover is Maya, a patient with peg lateral incisors and altered passive eruption. In situations like these, simply restoring the lateral incisor without addressing the surrounding teeth can result in a smile that feels unbalanced.

Through this course, I’ll show you how to integrate veneering with diastema closure to achieve beautiful, minimally invasive results.
