Surgident GBR Tenting Screw ∅ 1.4mm x 4mm x 2mm (TS-140 – 040) – Pack of 5

Description

Surgident GBR Tenting Screws are precision-engineered titanium fixation devices specifically designed for vertical and horizontal ridge augmentation cases requiring active space maintenance under a barrier membrane. Unlike standard fixation screws that only stabilize the membrane, tenting screws elevate and support the membrane above the bone defect — creating a protected volume that maintains the regenerative space and prevents membrane collapse during healing. The flat dome head of the screw acts as the tenting point under the membrane, while the threaded shaft anchors securely into native cortical bone. Available in four screw lengths (4, 6, 8, 10 mm) with a consistent Ø1.4 mm threaded body and tenting heights from 2 mm to 4 mm, the range covers the full spectrum of ridge augmentation scenarios. Each variant is supplied in a convenient pack of 5 for case-based use.

Key Features

Directions for Use

Case Planning

• Confirm the case requires active space maintenance using tenting screws — typical for vertical ridge augmentation, large lateral defects, or block bone graft alternatives
• Plan tenting screw positions on CBCT — typically 2-4 screws distributed across the defect area
• Select the appropriate length and tenting height based on bone availability and desired vertical augmentation gain
• Plan adequate inter-screw spacing to support the membrane evenly

Surgical Site Preparation

• Complete flap elevation and fully expose the bone defect requiring augmentation
• Decorticate the native bone surface to enhance vascularization and bleeding into the graft
• Identify the tenting screw positions and verify adequate native bone for anchorage

Pilot Drilling

• Use a 1.0 mm (or matching) pilot drill compatible with Ø1.4 mm tenting screws
• Drill pilot holes at each planned screw position with copious saline irrigation
• Adjust pilot hole depth based on the chosen screw length — full thread engagement is essential

Tenting Screw Insertion

• Engage the screw into the appropriate driver (sold separately or part of Surgident GBR fixation kits)
• Insert each tenting screw into its pilot hole, perpendicular to the bone surface
• Drive the screw clockwise under controlled rotation until the flat dome head reaches the planned tenting height above the bone
• Verify the screw is firmly anchored with no rotational play at the planned tenting height
• Repeat at each tenting position across the defect area

Graft Placement and Membrane Coverage

• Place the bone graft material around and between the tenting screws to fill the defect
• Position the chosen barrier membrane over the graft and tenting screws — the screw heads will support the membrane above the graft
• Fix the membrane periphery with bone tacks or fixation screws as planned
• Verify the membrane is tented above the defect and the regenerative space is well maintained

Flap Closure

• Achieve tension-free primary closure over the augmented site
• Suture per the planned protocol and provide post-operative instructions
• Allow the recommended GBR healing period (typically 4-9 months for vertical augmentation)

Screw Removal at Re-Entry

• At the re-entry appointment, expose the augmented site with a flap reflection
• Locate each tenting screw beneath the regenerated bone or soft tissue
• Engage the driver and unscrew each tenting screw counter-clockwise
• Proceed with implant placement or further prosthetic planning as per the case
