All implants are made of titanium (Tl6AL4V). Ti64 / TI6Al4V (titanium grade 5) is the most commonly used titanium alloy due to the good ratio between high strength and low density. Furthermore, the material TI6Al4V has a high resistance to corrosive media and has excellent biocompatibility.

All instruments can be used for all variations of DEWIMED O.S.A.S. screws. All instruments are available individually.

Direct or indirect anchorage

In principle, a choice can be made between a direct or indirect strategy. The direct variant is often technically simpler, with tooth movements directly supported by the stationary anchorage. Indirect anchorage entails the formation of a dental anchorage segment, which is stabilized by the screw, allowing for active tooth movements to occur.

Direct anchorage

Indirect anchorage: The tooth to be moved is anchored to a tooth that is connected to the DEWIMED O.S.A.S. screw.

Healing period of 4 days after removal

All of the familiar coupling elements used in orthodontics, such as round wires, rectangular wires, springs, and elastic chains, can be utilized. Each orthodontist can maintain their treatment strategy while leveraging the benefits of cortical anchorage. The removal process after successful treatment is straightforward. As the fixation of the non-osseointegrating DEWIMED O.S.A.S. screws is intentionally reduced after a
few months, the screws can be easily removed with a screwdriver, often without the need for anesthesia. The screwdriver fixes the screw by locking it in place, preventing any accidental slipping into the pharynx. Due to the mechanical minimal dimensions of the screw, they leave no traces after removal and ensure a swift, mucosa-covered healing of the intraoral penetration site.
