Product Description
The Open Cover Screw for Internal Hex Implant H2.43 is a precision-engineered component designed for secure sealing and controlled access to the implant during two-stage implantation procedures. It is specifically developed for implants featuring an internal hex connection H2.43 with 1-72 UNF internal thread, ensuring accurate fit and reliable clinical performance.
The screw features a 3 mm diameter body designed to effectively cover and protect the internal hex of the implant, while maintaining accessibility when required.
Manufactured from medical-grade titanium alloy (Ti-6Al-4V, ASTM F136), the component offers excellent biocompatibility, strength, and corrosion resistance. Its smooth external surface minimizes tissue irritation and supports optimal healing conditions.

Titanium Open Cover Screw
It has the same function as a standard Cover Screw - closes the internal connection of the implant. Open Cover Screw consists of a pin with a diameter of 1.25mm in height from 2 mm to 6 mm, which is located on the cap in the center and a screw for screwing into the implant. Open Cover Screw screwed to fix the implant with a hollow key (431238). The choice of Open Cover Screw depends on the thickness and height of the gums in the area of implantation. After the wound is sutured, the protruding pin should be located in the thickness of the gum. If the pin protrudes from the gum, it should be changed to Open Cover Screw with a lower protruding pin or cut. The speaker pin gives the doctor, at the stage of disclosure of the implant; it is easy to find the location of the implant, to make disclosure of the implant using a hollow key (431238) and a punch gum (471230).
Advantage of Open Cover Screw:
- no need to make a cut;
- there is no need to exfoliate the gums;
- no need to stitch;
- minimal loss of the gum with a diameter of 3.5mm above the implant;
- perforation of the gums in the center of the implant. (As a protruding pin, is the guide for the punch);
- there is no loss of height of the gingival margin;
- prosthetics can be started on the day of disclosure.
