Back Action Chisel Dental Instrument by Helmut Zepf

The back action chisel dental instrument is a surgical hand instrument for bone contouring, bone harvesting and flap work in periodontology and implantology, designed to work from angles that a straight instrument cannot reach. Helmut Zepf offers a range of back action chisel dental tools, from the Rhodes 36/37 and Buser curette bone scrapers to double-ended combination instruments with interchangeable tips.

What Is a Back Action Chisel?

A back action chisel dental instrument features a blade angled back toward the handle, so the clinician cuts or scrapes with a pulling stroke. This collection includes the Rhodes back action chisel 36/37 for bone material removal and bone contouring, Buser back action chisels that double as curette bone scrapers, and combination instruments that pair a 90° back action end with a dissector, Glickman knife or raspatory curette.

Key Features of Helmut Zepf Back Action Chisels

High-grade stainless steel construction for durability and corrosion resistance
Ergonomic handle design for enhanced grip and reduced hand fatigue during extended procedures
Precisely ground cutting edges for clean, controlled work on bone and soft tissue
Autoclavable to meet standard sterilization protocols in clinical environments
Manufactured to ISO standards for consistent quality and dimensional accuracy

Clinical Use

The back action chisels and combination instruments in this collection are used in periodontal and implant surgery: removing and contouring bone (Rhodes 36/37), scraping and collecting bone with the Buser curette bone scrapers, and dissecting, incising and reflecting tissue with the combination dissector, Glickman knife and raspatory curette instruments. The back action design is valuable where direct instrument angulation is restricted.
