Bone Harvesting

Harvesting Innovation For Your Regenerative Needs

Geistlich SafeScraper Twist®

Combining Versatility and Flexibility

SafeScraper TWIST provides an easy method for harvesting autogenous cortical bone for use in grafted sites with a minimally invasive technique.


  • Curved tip facilitates easy access to donor sites which makes it ideal for both minor and major harvesting procedures 
  • Ergonomic design provides excellent control during the harvesting procedure
  • Quality of harvested bone means presence of many viable osteocytes, and also osteoblasts, osteoclasts, and osteoprogenitor cells1
  • Promotes graft acceptance, neovascularization and bone regeneration2,3
  • Collection chamber capacity: 2.5 cc

Geistlich SafeScraper Twist®

Extra Volume Version of the SafeScraper Twist


  • Same performance while collecting larger bone volume
  • Redesigned blade with double grooves in the blade allow for three collecting surfaces
    • Cutting performance reduces patient discomfort
  • The VOLUMIZER continues to provide the established benefits of the proven SAFESCRAPER TWIST curve:

Geistlich Micross®

Enhanced Performance and Efficiency

Micross is a minimally invasive autogenous bone collector which allows clinicians to harvest bone better in narrow, difficult-to-reach areas.


  • Exclusive micro-blade allows easy bone collection
  • Narrow profile provides the ability for bone collection at the defect site
  • Designed for tunneling surgical techniques, minimizing patient discomfort
  • Collection chamber capacity – 0.25 cc

Frequently Asked Questions

Who is META and what are their products?

The gold standard in disposable instruments for harvesting autologous bone during dental procedures, Meta Bone Scrapers and Geistlich Bio-Oss® and Geistlich Bio-Gide® are typically used together in oral regeneration.

What are the key benefits of META bone scrapers?4,5

  • QUICK | SAFE | EFFECTIVE
  • Excellent quality of harvested bone chips for bone regeneration
  • Size and homogeneity
  • Retains inherent cells and growth factors
  • In comparison to harvesting and milling bone blocks:
  • Reduces Prep Time
  • Higher Safety -> Minimally invasive -> non-traumatic technique, no risk harming sensitive structures Superb blade: round shape offers high flexibility of angle, always sharp vs. reused devices

What are the key benefits of SAFESCRAPER TWIST Curve VOLUMIZER?4,5

  • SAFESCRAPER family line extension à Extra volume version
  • Same performance while collecting larger bone volume
  • Redesigned blade: Double grooves allow for three collecting surfaces
  • Enables rapid and accurate collection of autologous cortical bone
  • VOLUMIZER continues to provide established benefits of the proven SAFESCRAPER TWIST curve

Which META bone scraper product should be used in what situation?4,5,6

  • SAFESCRAPER TWIST: Gold standard for both extensive and minor harvesting procedures
  • MICROSS: Minimally invasive device for smaller harvesting procedures, for instance, in a tunneling approach
    (up to 0.25 cc per application) –
  • Blade sharpness allows for up to 2.5 cc in total (same patient); pen-like design facilitates collection even in hard-to-reach and near-to-the-defect areas

From which anatomical location should bone chips be harvested?

Harvestable volume and invasiveness differ between locations -> Patient-specific decision

Why are META bone scrapers disposable and must not be re-sterilized?

  • No contamination of the collected bone chips
  • Blade remains sharp to ensure optimal cutting performance to reduce patient discomfort
  • Accelerates harvesting time | maximum cutting efficiency
  • No need for sterilization and/or cleaning procedures
