• Premium surgical stainless steel formulation offers high tensile strength and exceptional resistance to corrosion.
• Linear shaft profile ensures direct-line force transmission during anterior or well-exposed surgical access.
• Dual-beveled 4mm working edge executes clean osteotomy cuts with reduced local bone fragmentation.
• Etched depth calibration markings allow continuous, real-time depth monitoring throughout force application.
• Solid proximal impact platform efficiently receives manual force from surgical hammers or mallets.
• Ergonomically balanced handle provides a confident grip to minimize hand strain during intricate procedures.
• Highly passivated surface maintains structural integrity under rigorous hospital autoclaving protocols.

The GDC Osteotome Chisel - Straight (4mm) (OSS6518S) is a specialized surgical hand instrument tailored for oral, maxillofacial, and dental implant surgical applications. Crafted from high-durability surgical-grade stainless steel, this instrument provides high rigidity and resistance to wear, making it suitable for delicate ridge-splitting operations, maxillectomy cuts, and alveolar ridge preparation.

Featuring a straight shaft design paired with a 4mm double-beveled tip, this instrument allows oral surgeons to perform direct osteotomy cuts and split osseous tissue with high tactical feel. The etched depth marks along the working end give clinicians precise visual feedback, preventing accidental over-penetration into underlying anatomical structures. Its heavy-duty handle and impact plate absorb standard mallet strikes smoothly, distributing the manual force evenly down to the cutting tip.

• Material: Surgical-grade stainless steel
• Tip Profile: Straight double-beveled cutting edge
• Tip Width: 4 mm
• Calibration Marks: Depth measurement lines etched on working end
• Impact Mechanism: Reinforced proximal end for surgical mallet use
• Reusability: Fully reusable and autoclavable
• Sterilization: Steam autoclave up to 135°C
• Product Code: OSS6518S

1 Pack Contains:
• 1 × GDC Osteotome Chisel - Straight (4mm) (OSS6518S)

Prepare and expose the surgical field using standard sterile protocols and appropriate anesthesia.

Inspect the osteotome tip and depth markings to confirm proper instrument integrity and size selection.

Position the 4mm straight cutting edge precisely onto the targeted cortical or cancellous bone.

Align the instrument shaft along the planned trajectory to ensure directional control of the cut.

Apply controlled taps with a surgical mallet onto the proximal end to advance the blade through bone.

Verify depth progress continually using the integrated laser markings on the working tip.

Irrigate the osteotomy site routinely with sterile saline solution to cool the tissue and clear debris.
