The back action chisel by Buser (Helmut Zepf No. 24.495.01) is a precision-engineered instrument designed for exacting bone preparation and curette scraping procedures in oral surgery and implantology. Available in dual working widths of 3 mm and 4 mm, this instrument delivers versatile, controlled osseous manipulation across a range of clinical scenarios.Instrument OverviewThe back action chisel configuration positions the blade to engage bone tissue via a pulling stroke rather than a conventional push. This geometry provides enhanced tactile feedback and greater precision when contouring alveolar bone margins — making it particularly valuable in guided bone regeneration (GBR) procedures, socket preparation, and periosteal elevation where delicate tissue management is essential.Key Features Dual working end sizes: 3 mm and 4 mm Back action (curette) blade geometry for a controlled pull-stroke technique Manufactured in Germany to rigorous quality standards Compatible with standard sterilization protocols Ergonomic handle design for sustained clinical use Quality and OriginCarrying a Made in Germany designation, this back action chisel is produced under the stringent manufacturing conditions associated with Helmut Zepf's established reputation for high-quality dental and surgical hand instruments. German-made instruments in this category are widely recognized for dimensional accuracy, material integrity, and long-term durability through repeated sterilization cycles.Clinical ApplicationThe Buser back action chisel is suited for oral surgeons, periodontists, and implant specialists who require reliable, consistent instrument performance during bone contouring, graft site preparation, and fine osseous trimming. The 3 mm variant is ideal for narrower anatomical sites, while the 4 mm version addresses broader working areas with equal precision.1-Year WarrantyThis Helmut Zepf instrument is covered by a 1-year warranty against defects in materials and workmanship from the date of delivery.60-Day Returns — Any Reason, Even If UsedPut this instrument to work in your practice.
