Rugged-Force Obwegeser Alveolar Osteotome for High-Accuracy Ridge Expansion
The Obwegeser Osteotome for Alveolar Process is a specialized component of the dental reconstructive toolkit, specifically engineered for the vertical and horizontal expansion of atrophic alveolar ridges. Functioning as a high-performance crestal separator, this instrument features a thin, bi-beveled blade that facilitates the gradual separation of cortical plates while preserving the vascularity of the bone. Adas Instruments ensures that each alveolar bone chisel is balanced for precise force transmission, allowing for predictable bone manipulation without unwanted fractures. We ship USA, Europe & worldwide via DHL, FedEx, and UPS to deliver German steel instruments that surgeons trust for their anatomical accuracy and structural resilience.
Why Implant Specialists Choose Our Alveolar Osteotome
- Slim-Line Blade Geometry: Features a refined, tapered edge to act as a versatile crestal separator, allowing for atraumatic entry into narrow bone sites.
- Steady-Grip Ergonomics: Specifically designed with a flattened, wide-profile handle to function as a reliable alveolar bone chisel, providing the surgeon with superior stability and anti-rotation control during mallet strikes.
- Atraumatic Force Delivery: The graduated blade thickness ensures that lateral expansion pressure is applied evenly, minimizing the risk of labial or lingual plate fracture.
- Ever-Sharp Resilience: Forged from high-tempered surgical stainless steel to ensure the cutting edge remains sharp and resistant to bending through repeated autoclave cycles.
Primary Surgical Applications
- Splitting the alveolar ridge to increase bone width for dental implant installation.
- utilizing the crestal separator function for horizontal bone grafting and site preparation.
- Performing efficient alveolar bone chisel maneuvers during minor maxillary or mandibular osteotomies.
- Gently expanding the cortical plates in cases of narrow bone volume (Ridge Expansion Technique).
