Designed for long-term mechanical stability.
The EVERGUARD® Connection with an internal hex and external stabilization ring, ensures optimal long-term mechanical stability of the implant abutment connection.
For optimal soft tissue response.
The TISSUEGUARD® Collar encourages soft tissue adaptation to prevent bone loss and allows for surgical flexibility if needed.
We produce all Thommen implants from coldworked cp Titanium Grade 4. This material combines mechanical strength with excellent biocompatibility. INICELL ® is the conditioned state of the sandblasted and thermal acid-etched Thommen implant surface. Conditioning occurs immediately before implantation through contact with the conditioning solution. The result of this process is increased surface energy and improved wettability due to superhydrophilic properties, without any change of the clinically proven microroughness of the Thommen implant surface.
Biologically improved wettability leads to a homogenous adsorption of proteins on the implant surface. This leads to more activated thrombocytes and a homogenous, thicker blood clot network in the early stages of wound healing. On the molecular level, MMPs, BMP-2 and VEGF are present in higher concentrations on the INICELL® surface, accelerating the osseointegration process.
After 14 days, the INICELL® surface shows 40% more bone-to-implant contact (BIC), in contrast to unconditioned surfaces.
The INICELL® surface, which is immediately bioavailable, supports and accelerates the physiological processes during wound healing and early osseointegration.
The sandblasted and thermal
acid-etched Thommen implant surface.
The result is faster osseointegration and therefore a shorter healing time
of INICELL® implants.
This reduces the risk of early failure in the transition from the mechanical primary stability to the biologic long-term secondary stability of osseointegration.
Only with the APLIQUIQ® conditioning system can you generate the alkaline and superhydrophilic surface INICELL® chairside immediately before implantation. The conditioning solution is stored separately from the implant in the cartridge.
By pressing the cartridge and subsequent vigorous shaking, the implant is covered and activated by the conditioning solution.
The conditioning solution is strongly alkaline, with a pH value over 12.
The free hydroxylions (OH–), responsible for the high pH value, have an antimicrobial effect.
It protects the implant surface from the removal of the product from the sterile packaging until the first blood contact. The high pH is immediately buffered by the blood, and at the same time the superhydrophilic implant surface allows spontaneous and homogeneous protein adsorption, creating the basis for fast and successful osseointegration.
Simple Use. Instant Application.

The implant abutment connection lies at the heart of any implant system.
It is the link between the implant which is anchored in bone and the prosthetic restoration. The implant abutment connection must enable aesthetically pleasing prosthetic restoration and maintenance must be worry free.
The internal hexagon of the EVERGUARD® Connection is manufactured with the highest precision and allows an extremely accurate transfer of the implant position to the master model, which in turn ensures a perfect fit for the prosthesis. The internal hexagon also provides precise rotational orientation and stability for single-tooth implant restorations thanks to the large, indexed contact surfaces.
A unique feature of the EVERGUARD ® Connection is the stabilization ring on the implant platform. This stabilization ring self-centers the abutment on the implant and carries the bulk of lateral chewing forces. It gives optimal mechanical stability to the implant abutment connection and minimizes micro-movements at the implant abutment EVERGUARD® Connection Designed for long-term mechanical stability The EVERGUARD ® Connection is designed for long-term mechanical stability and has proven itself through more than 35 years of clinical practice. With an internal hex and external stabilization ring, the EVERGUARD ® Connection ensures optimal long-term mechanical stability of the implant abutment connection. interface close to the bone and soft tissue.
Additionally, the stabilization ring focuses the contact area between the implant and abutment so that there is higher surface compression in the critical perimeter area of the connection with comparatively modest torque used on the abutment screw.
This minimizes the micro gap between the implant and abutment which reduces the occurrence of bacterial contamination.
The EVERGUARD® Connection design includes an axial stop for consistent abutment position.
Axial discrepancies, which can occur with conical connections are avoided and a perfect passive fit can be achieved even for complex multi-unit screw-retained restorations. In addition, the axial stop of the EVERGUARD® Connection eliminates the wedge effect observed with conical connection caused by the abutment sinking. This wedge effect reduces the preload of the abutment screw, which leads to screw loosening.
This wedge effect reduces the preload of the abutment screw, which leads to screw loosening.
To compensate for the preload loss caused by the wedge effect in actual clinical practice, the appropriate torque must be applied regularly and repeatedly after the functioning of the implant prosthesis.
The axial stop of the EVERGUARD® Connection preserves the abutment screwʼs preload.
The smallest abutment screw in the world
The abutment screw of the EVERGUARD® Connection has a small screw head with a diameter of 1,6 mm respectively 1,9 mm compared with more typical diameters of 2,2 mm to 2,6 mm.
The small screw head is possible because it does not need to withstand the higher clamping forces which other designs may require and it is protected from lateral loads by the stabilization ring.
The small screw head allows abutments to be produced with a narrower screw channel and thicker walls. This in turn gives the dental technician more freedom for prosthetic design and fabrication for a strong and esthetic result.
more freedom for prosthetic design
The abutment screw utilizes a proven reduced diameter shaft (anti-fatigue shaft), a common component in engineering that is used in the design of connections that are subject to strong dynamic loads. An anti-fatigue shaft screw differs from a normal screw in that the shaft is subject to small elastic deformation when exposed to tension and acts like a spring.
In addition to its physical design, optimal fatigue properties of the abutment screw are ensured by the use of a high- strength titanium alloy (TAN). The selected titanium alloy has excellent biocompatibility and is widely used in orthopedic devices.
The MONO Torque Ratchet
the reddot design award for the best product design
- An example of another excellent characteristic of Thommen design which stands out can be mentioned in passing: its outstanding design.
- The MONO torque ratchet – as well as the APLIQUIQ® container – for chairside-conditioning – which were both awarded the reddot design award for the best product design out of several thousand competitors from 60 countries.
manufactured from a solid billet of high-strength titanium alloy
- Conventional ratchets consist of several parts, have recesses and are thus generally hard to clean. The MONO torque ratchet from Thommen Medical is manufactured from a solid billet of high-strength titanium alloy.
- The torque ratchet can be used as a simple insertion/removal device, with control of the torque from 10 to 35 ncm possible. In combination with the MONO insertion device short, the MONO torque ratchet can also be used for competitor implant systems.
Due to the collar, the implant-abutment connection lies in most cases in the soft tissue, which results in an optimal healing situation for both, the soft tissue and the underlying bone. It also allows for easier impression taking and inserting or replacing the prosthesis.
The machined surface of the collar is optimal for soft tissue and is cleansable, which improves hygienic maintenance to reduce the risk of biologic complications including peri-implantitis.
It is of great benefit over the entire life of the implant that the prosthetic platform is within the soft tissue since the collar and the adjacent soft tissue form a safety zone above the bone.
Stable soft tissue adaptation is formed around the machined collar
- The straight design of the collar facilitates hygienic maintenance due to good accessibility and visibility. Since the immunologic defense takes place in the soft tissue in the event of inflammation, it is important to manage this safety zone properly over time. The collar acts like a safety belt and enables an easier cleaning.
- When designing the implant-abutment connection, we dedicated special attention to the interface. From a biological point of view, any bacterial colonization is highly undesirable, which is why the interface is manufactured as smooth and precise as possible. The collar-abutment design supports the patient’s daily maintenance as well as probing and scaling upon hygiene visit.
”Due to this perfect
connection we notice extremely
stable bone conditions”.
