API+ GMT 29 Hollow (G29)

API+ GMT 29 Hollow (G29) is a precision restorative cutting instrument designed for trimming, smoothing, and shaping the gingival floor of cavity preparations. It is especially effective for creating axiopulpal bevels in Class II amalgam restorations and for removing lips of undermined tooth structure at the gingival cavosurface margin.

Gingival Margin Trimmers (GMTs) are modified hatchets with working ends featuring opposite curvatures and bevels. When held at the correct angle and used with a pushing motion, the GMT 29 delivers accurate beveling on enamel margins, making it indispensable for inlay and onlay preparations.

Manufactured from high-quality stainless steel, the API+ GMT 29 Hollow offers excellent corrosion resistance, durability, and reliable performance. The hollow handle design ensures a lightweight feel and improved control during restorative procedures.
