This study presents a novel dental technique for restoring cavities below the gum line using a specialized cervical matrix and glass ionomer cement. This method ensures effective material placement for subgingival restorations.

Area of Science:

  • Dentistry
  • Restorative Dentistry
  • Dental Materials

Background:

  • Caries extending below the gingival crest pose challenges for traditional restoration techniques.
  • Achieving a proper seal and material adaptation in subgingival cavities is difficult.
  • Existing methods may require extensive soft tissue manipulation or complex procedures.

Purpose of the Study:

  • To describe a new technique for placing dental restorations in cavities located apical to the gingival crest.
  • To detail the use of a semi-rigid cervical matrix for subgingival lesion management.
  • To explain the application of glass ionomer cement via a modified matrix in difficult-to-access areas.

Main Methods:

  • A semi-rigid cervical matrix is positioned apical to the gingival border of the subgingival lesion.

  • An opening is created in the matrix superior to the soft tissue level.
  • Glass ionomer cement is inserted through this opening, ensuring adaptation to the prepared cavity.

    • Main Results:

    • The described technique allows for the effective placement of glass ionomer cement in subgingival cavities.
    • The semi-rigid matrix provides a stable boundary for material insertion.
    • The method facilitates restoration of lesions extending below the gum line without significant soft tissue displacement.

    Conclusions:

    • This technique offers a viable approach for restoring subgingival dental caries.
    • The use of a modified cervical matrix simplifies the placement of restorative materials in challenging locations.
    • Further studies may explore the long-term efficacy and clinical outcomes of this method.
