The Camlog implant system - Camlog - Dental Implant Products

This is the new standard when it comes to stability and handling: The Camlog? implant system changes implantology.
The patent protected "tube-in-tube-design" provides for a very precise, mechanically strong and rotationally stable implant-construction connection. The system involves a minimum of components. Clinicians, dental technicians and assistants will find it is easy to survey and extremely user friendly.
Introducing the System
Dr. A. Kirsch, Dr. K.-L. Ackermann, ZTM G. Neuendorff and W. D?rr who made up the development team could base their research upon 25 years of experience in implantology and prosthetics. The development of the Camlog? implant system was aiming to create an innovative, practice oriented implant system and was undertaken in order to set new standards in the field of implant-construction connection [Figure1].
Through the utilization of the latest scientific findings and the clinical experiences of many years the Camlog? system was conceived with a completely new approach. It involves a minimum of components. Clinicians, dental technicians and assistants will find it is easy to survey and extremely user friendly.
The constant critical assessment of practical experiences and the results gained by it brought the development of the Camlog? system on its way in 1995. Thus making innovative and superior ways of therapy possible.
Advances in manufacturing technology and Camlog's rich experiences in the manufacturing of different implants and implant abutments have been translated directly into the Camlog? system products.
The Design of the Implant Connection
In the cylindrical part, all Camlog? implants have three symmetrically arranged slots (? 0.5 and 0.7mm, depth 1.2 mm). Beneath this area, it follows an upper interior thread into which the gingiva-formers are to be screwed. Underneath it there is, caudal, a further cylindrical part and a second interior thread M 1.6 (to receive the fixing screw for impression pole and abutment) [Figure 2].
On all of the Camlog? implants (cylinder implants, screw-cylinder implants and root type implants), are three clearly visible points milled (? 1 mm) into the outer surface of the implant or on the insertion part. At implantation one point is aligned vestibularly by using the mark at the insertion part [Figure 3].
In- and outside of the implants as well as of the connecting components solely received metal-cutting treatment on a turning lathe. Therefore, the tolerances can be kept very small. The result is excellent accuracy in the fitting of the parts without adverse effects upon the structure of the material. Because of this, the patented new tube-in-tube design of the implant/abutment connection is extremely precise, mechanically very strong and rotationally stable. This means the micro movements of the prosthetic elements are significantly reduced [Figures 4 / 5].
Studies showed that, with the Camlog? system, loosening of the screws is prevented by the backlash-free fit between implant and abutment. This even applies when the screws are tightened by hand. This fit was made possible by a new method of manufacturing, which by now has been affirmed by more than 2000 implants.
Camlog? abutments are caudal tubularly elongated (5.4 mm) and have three cams at the upper part. They correspond in terms of the distance to the interface on the upper rim of the implant to the three slots of the implants. When the impression poles or the abutments respectively are inserted, their caudal tubular elongation provides for easy, quick and safe orientation in the implant's longitudinal axis, long before the three cams are sitting on the upper rim of the implant. The abutment is twisted until it slides perceivably into the slots and hence into its final position [Figure 6].
The external hex is at present the most widely-used implant/abutment connection. It is a purely tensionally-locked connection, i.e. all force is transfered by the fixing screw. Thus, this screw needs to be initially tightened with a high torque. This can only be achieved if a torque spanner is used. The permanent bending load at lateral force application leads to slackening and fatigue fractures.
Nearly all the Camlog? system's implant/abutment connections, however, are form-closed connections.The initial tightening's influence upon the fixing screw is minimal, because the lateral forces are absorbed via the tube-in-tube system. In mechanical engineering one generally speaks of a form-closed connection if the relation of the diameter to the insertion depth is bigger than 1.4. Regarding the Camlog? system, the diameter / insertion depth relation is between 2.4 and 1.5. This new and world-wide patented implant/abutment connection of the Camlog? system leads to the following results: approximately 60% higher values in continuous running tests and approximately 90% higher values in structural strength, compared to the minimum values prescribed by the FDA.
When it comes to the Camlog? system, force is flowing into the implant through the tube-in-tube connection over the entire insertion depth. Thereby, tensions are dispersed which then leads to low local load values [Figure 7].
