ADS® surface treatment

To promote the adhesion and growth of bone cells, the outer surface of the implant has been treated with the exclusive ADS® treatment (Advanced Double-Grip Surface) which combines a white corundum micro-bubble treatment and acid etching, for a non-smooth roughness that maximizes the contact surface between implant and bone and therefore improves stability and adhesion between them.

The ADS® treatment is the result of a series of collaborations with institutes and universities, as well as our own research and tests, that allow us to monitor and validate the optimal biological response to the implant surface: chemical (X-ray scattering studies to find out the composition of the implant and its surface) and topography studies (roughness studies) have been carried out, as well as biological (in vivo response studies in animals) and clinical studies. 

Composition studies

X-ray scattering studies show that the surface of the implants is only made of titanium and oxygen, which are the basic components of the oxide layer that is formed in the implant passivation process and that gives it its excellent corrosion resistance.

Surface topography studies

In order to control and identify the topography of the implant surface, roughness studies were performed with profilometer, as well as with techniques such as SEM (Scanning Electron Microscope) and CLSM (Confocal Laser Scanning Microscope), allowing to obtain and control the mean roughness (Ra) values within the parameters recommended in international publications.

Osseointegration studies

To determine the biological response of gmi implants, in vivo studies were conducted by inserting the implants on animals, leaving them without load during the healing process and performing a histological study to prove the excellent response of the bone cells and the complete osseointegration of the implant.

gmi avantgard PEAK conical connection implants are packed in a screen-printed cardboard box, with three traceability labels and a double packaging containing the implant system, with the secondary packaging made of technical plastic and the primary packaging made of Pyrex glass to ensure the inert performance of the container. Once packaged in a clean room, they are sterilized with gamma radiation according to regulations.

The new packaging system of the gmi avantgard PEAK implants consists of a titanium support which houses the implant-implant carrier set, prepared to be inserted directly into the mouth, using a single hex-2.45 mm implant carrier wrench, designed for this purpose. This new system offers the odontologist the following advantages: more control and a better view of the implant insertion process, it is easier to use in reduced interdental spaces and a reduction in surgery time.*

*   Consult the instructions for use in electronic format.

1. Check sticker indicating implant diameter and length and open the tab on the carton.
2. Remove the secondary packaging and product identification labels.
3. Check the integrity of the safety seal and unscrew the plug on the secondary packaging.
4. Remove the primary packaging from the secondary packaging avoiding hitting it against a hard surface.
5. Extract and save the primary packaging plug making a lateral movement.
6. Insert the RP insertion wrench facing the grooves of the wrench with those of the implant. Apply moderate pressure to drive the wrench into the implant well.
7. Check that the wrench is fully inserted and turn slightly while gently pulling on the assembly.
8. Place the implant in the bone bed by applying a torque of 35 N·cm until the treated area is at the crestal or subcrestal level. Remove the wrench with gentle lateral movements.
9. Remove the cover screw from the primary packaging plug, using the HEX-1.20 mm wrench.
10. Screw the cover screw to the implant by applying a maximum torque of 15 N·cm. Remove wrench and suture the incision.

The following is a description of the drilling sequences for the different conical connection implant models, as well as the recommended drilling conditions for their use:

• Ball and initial drill: 1000 rpm.
• Step and conical drills:

- ø2.00 / ø2.80 mm: 500 - 700 rpm.

- ø3.20 / ø3.65 mm: 500 - 700 rpm.

- ø3.70 / ø4.15 mm: 400 - 700 rpm.

                 - ø4.15 / ø4.65 mm: 400 - 600 rpm

        • Cortical drills: 200 - 400 rpm.
        • For drilling, external cooling with saline solution is required.

The gmi avantgard PEAK implant range was designed and tested to be inserted as a single restoration, with a 30-degree maximum inclination to the perpendicular plane to the occlusal plane, in accordance with the following diagram.

The gmi avantgard PEAK implant range is designed to be inserted applying a 35-40 N·cm torque, although it can bear a maximum tightening torque of a 60 N·cm. gmi recommends manual insertion of the implant with a dynamometric ratchet wrench to ensure that these values are not exceeded.

The gmi avantgard PEAK range of implants and prosthetic attachments are designed and manufactured with tolerances intended to maintain adjustments that minimize the clearance between components and therefore guarantee the stability of the connection. gmi recommends the use of original attachments to ensure a perfect fit between the components of the restoration.

To prevent prior deformation of the clinic screw, gmi recommends restricting its use only for the final tightening of the prosthesis. To make adjustments during the prosthetic procedures, use of the laboratory screw is recommended.
