PFM BUR Kit (TC-11, TF-13, EX-11, FO-25, TF-13F)

Porcelain-Fused-to-Metal (PFM) restorations demand a highly specific, dual-margin preparation geometry. You need adequate depth on the facial surface to mask the metal substructure without over-tapering the preparation, alongside a highly conservative reduction on the lingual metal collar.

The Dentaura PFM Crown Preparation Kit is a purpose-built, 5-bur sequence designed to eliminate the guesswork from this complex procedure. Starting with rapid interproximal clearance and transitioning through bulk axial reduction, occlusal clearance, and final margin refinement, every instrument in this kit serves a strict clinical purpose.

Engineered with premium diamond particles and perfectly balanced concentric shanks, this kit ensures smooth cutting efficiency, preventing chatter and minimizing trauma to the vital pulp and surrounding periodontium. It is the ultimate refined workflow for aclassic fixed prosthodontics.

Kit Contents & Clinical Roles

• TC-11 (Tapered Conical, Standard): Designed to safely and rapidly break tight interproximal contacts without nicking the adjacent tooth.
• TF-13 (Taper Flat End, Standard): The primary workhorse for bulk axial reduction. The flat end establishes a distinct, crisp 1.0mm - 1.2mm shoulder margin on the buccal/facial aspect to accommodate the metal coping, opaque, and porcelain layers.
• EX-11 (Specialty Shape, Standard): Specifically contoured for anatomical occlusal reduction and creating the necessary concave clearance on the lingual/palatal surfaces of anterior teeth.
• FO-25 (Flame Ogival, Standard): Ideal for lingual/palatal reduction
• TF-13F (Taper Flat End, Fine): The essential finishing instrument. It seamlessly traces the buccal shoulder created by the TF-13 to remove microscopic roughness, J-lips, and unsupported enamel, ensuring a perfectly smooth margin for the final impression.
