Solid, stable and reliable for over 20 years: ANKYLOS C/X is the answer for all clinical indications – with its predictable, natural esthetics and top mechanical stability. The tapered connection is designed for initial and long-term tissue stability. The extremely accurate TissueCare Connection has virtually no micromovement and is almost totally bacteria-proof. And it is also keyed and friction-locked – to prevent bone resorption and to ensure stable and healthy hard and soft tissue.
Stable, predictable results for you and your patients? ANKYLOS C/X is the answer: The unique tapered TissueCare Connection transfers the transition between implant and abutment to the center of the implant and prevents mechanical influences on it and microbial attack on the peri-implant tissue. It provides additional space on the implant shoulder for the surrounding soft tissue. In combination with subcrestal placement and the microstructured implant it enables deposition of bone cells up to the abutment – for additional support of the overlying soft tissue. Ideal conditions for lasting red-white esthetics.
Ease of use with maximum functionality and esthetically demanding results? The new ANKYLOS C/X placement system enables accurate positioning of implants with a view of the implant shoulder even with subcrestal placement. The progressive thread design makes it easy to screw the implants into position and enhances tissue retention. The keyed and friction-locked TissueCare Connection makes surgery and prosthetics completely independent from each other. And with only one diameter for all prosthetic components any abutment can be combined with any implant as desired – now with the option of indexing. For a brilliant result over the long term and economical treatment combined with lower storage requirements.
The new way of seeing things
Success in implantology is based on the love of detail. Lasting results can only be achieved by those who can see the interconnections. And who are open for other points of view. DENTSPLY Friadent stands for a change of perspective in implantology. The new way of seeing things is aimed at long-term hard and soft tissue stability. And also on lasting red-white esthetics.
Make space for long-term results
Implant surface, position in the bone, type and geometry of connection, to name just some examples: how and why bone and soft tissue remain stable is determined by more than one factor. Research and clinical experience have shown which five factors are the most important. Ultimately all details must interact in the right way. This is the only way to make implant-borne restorations successful over the long term.
Five points for initial and long-term tissue stability
1- No micromovement
2- Bacteria-proof connection
3- Platform Switching
4- Subcrestal placement
5- Microroughness to the interface

Micromovement between the implant and abutment irritates the peri-implant bone. It reacts by atrophying in the area of the implant shoulder, referred to as remodeling. In contrast, keyed and friction-locked connections prevent any micromovement. They form a virtual single-component implant, which ensures stable tissue from the start.
The only way to form a bacteria-proof keyed and friction-locked connection is for the conical surface to be flush with the mating surface
Gaps between implant and abutment lead to bacterial colonization. Chewing loads cause a relative movement between the components, which in turn causes a pumping effect. This distributes endotoxins, causing an infectious reaction in the tissue at the implant-abutment interface level. Bone is resorbed below the implant-abutment connection until the biological width is established. Only a bacteria-proof connection prevents bone resorption – and stabilizes the soft tissue.
Platform Switching combined with a stable, bacteria-proof connection design is an important factor in tissue stability (x-ray: Dr. Nigel Saynor, Stockport, UK).
Platform Switching moves the transition between implant and abutment to a central position. This removes mechanical and microbial irritation from the peri-implant tissue. The biological width is moved from the vertical plane to the horizontal plane. This makes Platform Switching an important factor for tissue stability – but only in combination with a micromovement-free, bacteria-proof connection design. This is referred to as Platform Shifting. The narrower abutment also provides more space for peri-implant soft tissue.

A natural emergence profile is easier with subcrestal placement. Bacteria-proof connections without micromovement prevent bone resorption and are tolerated by the bone even when the implant is inserted at a greater depth. Platform Shifting in combination with subcrestal placement and a microstructured implant shoulder allows bone apposition to the abutment and ensures excellent red esthetics over the long term.

An implant shoulder with a microstructured surface favors deposition of bone cells. When positioned subcrestally this means that bone can also form on the horizontal shoulder surface. The overlying soft tissue has additional support – favoring successful long-term results.
In a radiographic and histological animal study the implant shoulders were placed in the front tooth region 1 mm below the bone margin in conformity with an esthetic indication to simulate the deep position of the implant-abutment connection point in the region of the bone support of the papillae. Standardized x-ray images were taken at monthly intervals. In addition to other results the peri-implant bone margin around the conical connection remained significantly higher over the six months of the study compared to the position with a blunt abutment connection with an external hexagon (x-rays: Dr. Dietmar Weng, Starnberg)
