Description:

The IMP 22462 Twist Drill 4.2, 8–19mm is a precision surgical instrument developed for controlled osteotomy creation in implant dentistry. With a 4.2mm diameter and graduated depth markings from 8mm to 19mm, this drill offers versatility across a broad range of bone anatomies and implant protocols.
Fabricated from surgical-grade stainless steel, the drill’s sharp flutes and spiral geometry enable smooth, low-resistance cutting while minimizing heat buildup. This reduces thermal trauma to surrounding bone and supports preservation of biological integrity. The spiral profile also enhances debris removal and irrigation flow, keeping the osteotomy site clean and improving visibility throughout drilling.
Laser-etched depth indicators ensure accurate site preparation aligned with implant length and diameter. These high-visibility markings allow clinicians to monitor progress intraoperatively with confidence—supporting both guided and freehand placement approaches.
Its 4.2mm diameter makes the drill well-suited for final or near-final preparation of osteotomies for corresponding implant sizes. Compatible with most surgical handpieces, it integrates easily into standard tray setups, whether used in anterior esthetic zones or posterior support regions.
Designed for durability and repeated sterilization, the IMP 22462 is fully autoclavable and corrosion-resistant, ensuring consistent performance across multiple cases. By creating atraumatic and dimensionally accurate osteotomy channels, the drill plays a critical role in establishing primary stability and optimizing conditions for successful osseointegration.
