Introduction

Black triangles, or open gingival embrasures, are a common concern for dental patients. Historically, treatment options have been limited or invasive, including veneers, crowns, or orthodontic interproximal reduction (IPR). This webpage introduces an innovative, minimally invasive solution using injection-molded composite dentistry.

Causes of Black Triangles

Several factors contribute to black triangles, including:

  • Decreased interproximal bone height due to periodontal disease or surgery.
  • Excessive embrasure space and papilla deficiency.
  • Thinning gingival biotype and natural aging.
  • Orthodontic treatments that alter tooth angulation.

Innovative Solution: Injection-Molded Composite

Dr. David J. Clark’s technique involves:

  • Thorough biofilm removal using air/water/abrasive slurry.
  • Matrix selection and precise contact management.
  • Injection molding using heated flowable and paste composite.
  • Polishing with a simplified two-step process.

Case Study: Aesthetic and Functional Success

A patient with black triangles underwent injection overmolding on the four maxillary incisors. The results included:

  • Natural color blending with the tooth structure.
  • Minimal staining and long-term stability.
  • Improved gingival health and aesthetics.

Key Benefits: This technique preserves natural tooth structure, provides a long-lasting solution, and improves patient satisfaction without invasive procedures.

Conclusion

The injection-molded composite technique offers a revolutionary, minimally invasive solution for black triangles. Dentists interested in advanced composite techniques should explore the benefits of Bioclear Matrix systems.
