Bone Expansion Screws (Screw-Tome System)

This set of specialized Bone Expansion Screws (part of a bone expander or Screw-Tome system) is engineered for atraumatic alveolar ridge expansion, bone condensation, and crestal site preparation in narrow or soft bone ridges during dental implant procedures. Designed to be used sequentially, these self-threading screws compress and displace bone laterally without requiring traditional bone removal or heavy malleting techniques, thereby preserving bone volume and enhancing primary implant stability.

Specifications & Diameters

The five graduated expanders feature laser-etched depth markings and distinct color-coded base caps for rapid size identification during surgical workflows:

• Green Cap: Ø 2.6 mm narrow expander for initial site expansion.

• Red Cap: Ø 3.0 mm intermediate expander.

• Blue Cap: Ø 3.4 mm progressive expander.

• Black Cap: Ø 3.8 mm wide expander.

• Gold/Bronze Cap: Ø 4.3 mm maximum-diameter expander for final ridge widening.

Key Features

• Atraumatic Ridge Expansion: Gradually widens narrow alveolar ridges by compacting trabecular bone laterally, reducing surgical trauma and patient discomfort.

• Enhanced Primary Stability: Bone condensation around the expanded site increases local bone density, ensuring superior stabilization for subsequent dental implants.

• Laser-Etched Depth Markings: Calibrated depth rings allow clinicians to monitor insertion depth accurately relative to the crestal bone.

• Color-Coded Base Design: Distinct color rings enable fast, error-free sorting and sequence management chairside.

• Durable Surgical Construction: Crafted from high-grade medical stainless steel, ensuring full durability and compatibility with repeated autoclave sterilization cycles.
