Product Description
Knife Hand for Open Cover Screw
The Knife Hand for Open Cover Screw is a precision surgical instrument designed for soft tissue perforation and access to osseointegrated implants during second-stage implant surgery. The instrument allows controlled opening of soft tissue above the implant site to facilitate access to the implant cover screw and implant connection.
Manufactured from high-quality medical-grade stainless steel, the instrument provides excellent mechanical strength, corrosion resistance, dimensional precision, and long-term clinical reliability.
The precision working design supports atraumatic soft tissue perforation while improving surgical access and visibility during implant uncovering procedures.
The Knife Hand for Open Cover Screw is intended for use together with the Hollow Key 431230 for opening osseointegrated implants during the second surgical stage.
Suitable for:
- Second-stage implant surgery
- Implant uncovering procedures
- Soft tissue perforation
- Access to osseointegrated implants
- Implant restorative preparation
- Oral surgical procedures
The ergonomic instrument design provides stable handling and improved tactile control during surgical procedures.

Product Description
The Knife Hand for Open Cover Screw is a precision surgical instrument designed for atraumatic access to osseointegrated implants during the second surgical stage of modified two-stage implantation procedures.
The instrument is intended for use together with:
- Open Cover Screw (720838, etc.)
- Hollow Hex Key 1.25 mm (431238)
- Gum Punch (471230)
The system allows atraumatic implant opening without the need for surgical incision, flap elevation, or suturing during the second surgical stage.
The open cover screw is manufactured from medical titanium alloy Ti6Al4V ASTM F136 and features:
- Smooth outer surface
- 1-72 UNF fixation thread
- 1.25 mm hexagonal pin
- Pin length from 2 mm to 6 mm
The sharp upper pin allows identification of the implant location through soft tissue palpation after healing.
The Knife Hand instrument is manufactured from high-quality medical-grade stainless steel and provides excellent mechanical strength, corrosion resistance, dimensional precision, and long-term clinical reliability.
Intended Use
The Knife Hand for Open Cover Screw is intended for:
- Modified two-stage implantation protocols
- Atraumatic implant uncovering
- Soft tissue perforation
- Access to osseointegrated implants
- Implant restorative preparation
- Second-stage implant surgery
Indications
The instrument is indicated for:
- Opening osseointegrated implants
- Implant uncovering procedures
- Atraumatic second-stage surgery
- Removal of gingival tissue above implants
- Implant restorative access procedures
Contraindications
Do not use in cases of:
- Active infection at the implant site
- Improper implant osseointegration
- Incompatible implant systems
- Damaged surgical instruments
- Improper sterilization
Warnings
- All products are supplied non-sterile.
- Sterilization before use is mandatory.
- Only qualified dental professionals should use the instrument.
- Excessive force may damage surrounding tissues or implant components.
- Inspect all instruments before each use for wear or damage.
- Use only compatible DMi components and instruments.
Clinical Procedure
Modified Two-Stage Implantation Protocol
1. Implant Placement
- Place the implant according to the standard surgical protocol.
2. Installation of Open Cover Screw
- Install the Open Cover Screw (720838, etc.) into the implant.
- Use the 1.25 mm Hollow Hex Key (431238).
- Screw the component into the implant and lightly tighten it.
3. Soft Tissue Closure
- Perform hermetic suturing of the gingival tissue above the implant and screw.
- Allow healing and osseointegration according to the clinical protocol.
4. Implant Localization
- During the second surgical stage, locate the sharp pin of the open cover screw through soft tissue palpation.
5. Atraumatic Implant Opening
- Use the Gum Punch (471230) together with the Knife Hand for Open Cover Screw and Hollow Hex Key (431238).
- Remove the gingival tissue above the implant together with the open cover screw.
6. Prosthetic Stage
- Following implant opening, implant prosthetic procedures may begin immediately on the same day.
Advantages of the Technique
The modified two-stage implantation protocol allows:
- Atraumatic implant opening
- No gingival incision
- No flap elevation
- No secondary suturing
- Reduced surgical trauma
- Simplified second-stage surgery
- Faster prosthetic workflow
- Improved patient comfort
- Reduced healing time
Sterilization
