Bokonlon Dental Dual Trephine Drill for GBR Surgery | Double Cylinder Autogenous Bone Harvester Bur | High-Precision Oral Surgical Bone Collector

Product Overview

The Bokonlon Dental Dual Trephine Drill (Double-Cylinder Bone Harvester) is a highly specialized, professional-grade surgical rotary instrument engineered for advanced implantology and Guided Bone Regeneration (GBR) procedures. Harvesting a precise, uncompromised block or ring of patient-own autogenous bone tissue remains the clinical gold standard for graft predictability. By integrating a concentric dual-wall milling architecture, this premium bur allows oral surgeons to score, isolate, and capture perfectly proportioned bone cylinders with exceptional mechanical stability and minimal tissue trauma.

Key Features & Clinical Advantages

1. Double-Ring Coaxial Efficiency

Unlike standard single-wall trephines that can wobble or plunge unevenly, the dual-cylinder matrix functions as its own stabilizer. The concentric walls guide the cutting edge deep into dense cortical bone sections smoothly, ensuring the harvested osseous material retains uniform thickness and clean, predictable geometric margins.

2. Strategic Thermal Control & Large Side Windows

To eliminate localized friction heat that can cause thermal osteonecrosis, the bur incorporates large lateral side cut-outs. These evacuation windows allow high-volume sterile saline spray to directly access the internal and external cutting boundaries, actively flushing out bone slurry and simplifying chairside core block retrieval.

3. Precision CNC Balanced Construction

Manufactured on state-of-the-art multi-axis CNC machines in Shenzhen, this surgical bur features a rigid latch-type (RA) shank. This high-integrity balancing suppresses structural vibrations, offering the clinician smooth counter-force feedback even at lower rotational drilling speeds.

4. Full OEM/ODM Customization Capabilities

As an industry-focused source factory, Bokonlon provides comprehensive contract manufacturing. We can customize internal and external ring diameters, tailor specific wall thicknesses, adjust working core lengths, and laser-print private corporate branding onto the shanks for global dental distributors.
