Surgident Trephine Bur 20mm – Long Assorted (SD-LTBA)

Description

The Surgident Long Trephine Bur Assorted Set (SD-LTBA) is a comprehensive surgical instrumentation kit containing five precision-engineered trephine burs in graduated diameters for autogenous bone block harvesting, ridge augmentation core preparation, and implant retrieval procedures. The aggressive serrated cutting edges at the working end provide clean bone-cutting action while the hollow tubular design captures intact bone cores within the bur lumen — preserving valuable autogenous block grafts without fragmenting them. Available diameters of Ø4.0, 5.0, 6.0, 7.0, and 8.0 mm cover the full range of clinical harvesting scenarios, from small ramus or chin grafts to wider implant-retrieval cases. Graduated depth markings along each shaft provide visual depth control during drilling, and the 20 mm working length offers sufficient reach for posterior mandibular harvest sites. Supplied in a sterilizable stainless steel stand with labeled positions for organized chairside access.

Directions for Use

Pre-Surgical Planning

• Identify the clinical indication — autogenous bone harvesting, implant retrieval, or bone core preparation
• For bone harvesting: select the donor site (ramus, chin, tuberosity, or external oblique) based on the required graft volume
• For implant retrieval: measure the failed implant diameter via radiography and select the trephine 1 mm larger
• Plan the drilling depth based on the target bone volume or implant length

Pre-Operative Preparation

• Sterilize the complete kit via autoclave following the recommended surgical instrument protocol
• Achieve adequate local anesthesia at the surgical site
• Complete the flap elevation to fully expose the bone surface for harvesting or the failed implant for retrieval

Trephine Selection and Setup

• Select the appropriate diameter trephine bur from the stand based on the case plan
• Attach the bur to a compatible surgical motor contra-angle handpiece
• Set the motor to a low-speed range (typically 800-1500 RPM) with copious saline irrigation
• Verify firm bur engagement before contacting bone

Bone Block Harvesting

• Position the trephine perpendicular to the bone surface at the planned harvest position
• Apply controlled steady pressure with copious saline irrigation
• Drill to the planned depth using the graduated markings on the shaft for visual depth control
• Complete the core cut and gently rock the trephine to release the bone block
• Carefully remove the trephine — the intact bone core remains captured within the hollow lumen
• Push the bone core out of the trephine into a sterile container for grafting

Implant Retrieval

• Choose a trephine 1 mm larger than the failed implant diameter
• Center the trephine over the failed implant with the cutting edge engaging the bone around the implant
• Drill carefully to the implant depth, using copious irrigation to prevent bone heat damage
• The hollow trephine cuts a clean cylindrical osteotomy around the implant
• Remove the trephine and use appropriate forceps to extract the loosened implant from the site
• Manage the residual defect with appropriate grafting and membrane coverage as needed

Post Use Care

• Remove any captured bone particles from each trephine lumen using a sterile cleaning rod or brush
• Clean all burs with surgical-grade detergent under flowing water
• Use a non-metal brush to gently scrub the serrated cutting edges and lumen interior
• Inspect each bur for damage, dull edges, or wear before sterilization
• Sterilize the complete kit via autoclave following the standard surgical instrument protocol
• Return all burs to their designated stand positions for storage
