Ankylos is one of many implantation systems used in dentistry.
What is special about this system is the unique implant abutment connection. To illustrate this we will show you how a titanium abutment is screwed onto an implant. The implant is held using a forceps, usually inside the bone – and then a crown is mounted over the abutment.
Abutments are caps on implants, which serve as a base for a new crown. Abutments are usually mounted on the implants and secured by means of screws – they are plug-in connections. Ankylos was the first implant method to use a cone connection between an implant and an abutment. This minor difference had wide-reaching results.
For a long time, bone matter was observed to deteriorate immediately after the insertion of a denture. The upper sections of the implants would protrude from the gums, medically speaking a very bad sign. The x-ray clearly shows a concave area where bone matter has receded.
The surface of the implant is rough, which facilitates healing by enabling the bone to meld with the implant. However, this rough surface is also the ideal environment and hiding place for bacteria – as soon as the implant is no longer lodged securely in the bone, but instead protrudes into the mouth, the spread of bacteria and the resulting infection means the tooth is lost.
Attempts were made to counteract this process by smoothing out the upper sections of the implants. This was supposed to prevent the spread of bacteria in cases of bone deterioration – with some measure of success. Bone did not seem to deteriorate after Ankylos treatment, for reasons which were not at first clear. The surfaces were left rough since Ankylos was observed to result in thickening of the bone towards the abutment, so the edge of the implant had to be roughened up even more.
Another major difference which was observed and, at first, could not be explained, was that after Ankylos, when the abutment was unscrewed from the implant for cleaning, there was no foul odor, as had been the case with standard implants.
Now we know what causes these phenomena, namely the cone connection. In Ankylos, the abutment is secured so tightly onto the implant by the cone that not even a grid microscope can reveal any tolerance. Plug-in connections, on the other hand, exhibit an obvious gap where bacteria and bacterial matter take hold, while the motions of chewing cause movement between the abutment and the implant, which can clearly be seen in these special photographs – in Ankylos the cone connection allows no movement whatsoever.
The plug-in connection and the less-than-perfect fit between implant and abutment result in microscopic movement between the two and thus a pump effect. The mass of bacteria – which is what causes the foul odor – is pushed outwards, around the implant – which leads to a saucer-shaped area in which bone has deteriorated.
Firm, stable and reliable for over 20 years: ANKYLOS has passed all medical tests with flying colors – a predictable, natural look and high mechanical stability. The tried and true ANKYLOS connective method is designed for stable tissue from the beginning and in the long run.Ankylos
