GDC Margin Trimmer – 6 (Mt29h)

The GDC Margin Trimmer – 6 (MT29H) Margin trimmers, also known as gingival margin trimmers, are restorative cutting instruments used to cut enamel and produce a bevel on enamel margins. These dental instruments have slightly curved blades with sharp beveled cutting edges to provide mesial or distal access into the preparation.


  • Crown Preparations: Dentists use the Margin Trimmer to shape and refine the margins of a tooth that is being prepared to receive a dental crown. Precise margins are crucial for achieving a good fit and seal of the crown.
  • Bridge Preparations: When preparing abutment teeth for dental bridges, the instrument helps create accurate margins that ensure proper fit and support for the bridge.
  • Veneer Preparations: The instrument is also used in preparing teeth for veneers, ensuring that the veneer restoration fits precisely and provides a natural appearance.
  • Blade Design: Margin trimmers typically have slightly curved blades with sharp, beveled cutting edges. The curvature allows for easy access to mesial or distal areas of the preparation.
  • Beveling Capability: The sharp beveled cutting edges of the instrument allow for creating a bevel on the enamel margins. Beveling aids in achieving a smooth transition between the restoration and the natural tooth, improving aesthetics and preventing sharp edges.
  • Variety of Sizes: Margin trimmers come in various sizes to accommodate different clinical scenarios and tooth sizes. Different sizes are available to match the dimensions of the tooth being prepared.
  • Ergonomic Handle: The handle of the margin trimmer is designed for comfortable grip and control during the procedure, allowing the dentist to maneuver the instrument with precision.
  • Stainless Steel Construction: High-quality stainless steel is commonly used to make margin trimmers, ensuring durability, corrosion resistance, and ease of sterilization.
  • Autoclavable: Stainless steel construction allows margin trimmers to be autoclaved for proper sterilization between uses.
  • Precision Cutting: The sharp cutting edges and precise design of margin trimmers allow for controlled enamel removal without damaging the underlying tooth structure.
  • Smooth Finish: Margin trimmers create smooth and well-defined enamel margins, which are essential for the accurate fitting of restorations.
  • Versatility: While primarily used for crown and bridge preparations, margin trimmers can also be used in other restorative procedures where precise enamel shaping is required.
