WELCOME TO ELSNER LTD! Based on 20 years of CAD-CAM experience at Elsner Ltd and building on its commitment for innovative solutions and focus on high-precision manufacturing, the Elsner Dent division was created in response to challenges posed by modern dentistry. Our patented and high-precision system is there to solve the professional problems of dentists and dental technicians. Our state-of-the-art manufacturing equipment and our CE, ISO14001, ISO13485, ISO9001 and MSZ EN ISO13485:2012 certified manufacturing and development environment conforms to the highest standards. Our products reach our customers in a condition of guaranteed quality, which is the result of continuous quality control in production and management, complying with the above listed standards. Besides producing cement or screw retained crowns, bridges and custom-made structures, our world-class CAD-CAM system oﬀers revolutionary solutions from simple to very complex cases. ELSNER DENT Ltd is fully committed to innovation, which means we are continuously developing our products. To date, this policy has already brought a number of important innovations to the dental market. For example, the Elsner group has developed an innovative system in dental implant prosthetics, especially in the field of screw-retained restorations. We oﬀer unmatched solutions to overcome the diﬃculties of the screw retained supra-structures on compromised position dental implants.
Vario-Dock (universal abutment), Vario-Dock Plus (universal abutment combined with arched screw channel), Vario-Coping (universal impression coping) and Vario-Cast (axis-correction casting moulds). These new solutions were created in answer to the aesthetic and quality expectations of professionals and patients and represent our response to the challenges posed by dentists and dental technicians. Our system makes dental procedure easier, more aﬀordable, and more accurate, and now it is fully available on the market.
The patented innovations of Elsner System include Vario-Tube (arched screw channel),
UNIVERSAL ABUTMENT To date, in many cases it has not been possible to manufacture a screw-retained prosthesis on steep cone connection implants, as the divergence between the axes of impants largely limits their installation. (If the relative axial deviation in implants with two steep cones is larger than the cone degree in the implant, the dental structure is not embeddable.) Furthermore, in the majority of cases there is a need to change the vestibular or possibly the interdental orientation of the entry point of the fixation screw. Vario-Dock A is a patented solution (universal abutment), which can be employed in steep cone connection implants and oďŹ€ers a 25 degree axis correction in bridges. It is composed of a body and a threaded shaft, which together compose a fully closed unit. This is then completed by a lock nut (female screw), which fixes the tooth replacement onto the abutment. The main bodyâ€™s cone-shaped profile completely equivalent of the manufactured superstructure, but it is not fitted with a transitive screw, instead it is fixed in the implant by its own torque. There is a perfect fit between main body and implant on the conical surface, and since the main body is a non-penetrable component for bacteria, it hermetically seals the inside of the implant, preventing the communication between the inside of the implant and the oral cavity.

The coronal-oriented threaded shaft can be aligned in any direction within the 25 degree conical surface. This makes it possible at a superstructure level to optimise the joint orientation of supporting implant axes, making it easy to install the bridge. This also makes it possible to reposition the entry point of a fitting screw in both oro-vestibular and in mesio-distal dimensions, therefore in almost all cases these can be aligned into perfect position (occlusal central groove, or if needed palatal or lingual surface). As a result of its composition, Vario-Dock hermetically seals the inside of the implant, preventing screw loosening and significantly improves the superstructure’s micro-movement phenomenon. These features represent a breakthrough in implant prosthetics, therefore we place great importance on the further testing and development of these qualities. Vario-Dock B (universal abutment) developed for 90 degree hex implants.
There is some diﬀerence in surface fitting and therefore in the shape of the body compared to type A. Apart from this, its functioning, composition and advantages are essentially the same. Elsner System provides full compatibility between the various implant systems, therefore for a bridge replacement one can select a manufacturer’s component (implants with proper axes) combined with Vario-Docks A and/or B (implants needing axis correction, or multiple types of implants in the same restoration). Vario-Docks A and B can be fitted or loosened by their specific adapter tool. At permanent fitting the elements must be tightened by a maximum force defined by the manufacturer.
THE ARCHED SCREW CHANNEL Vario-Tube is a patented solution of Elsner System, which is capable of up to 25 degrees of axis correction. Whereas in the past an unfavourable axis orientation of the implant might have meant the dental structure could not be screw-retained, utilising Vario-Tube now makes this possible. Vario-Tube allows the repositioning of the endpoint of the hole both for a crown or a bridge, along a conical surface in all directions. Utilising Vario-Tube, you can change the arch of the hole so the nut entrance hole can be positioned on an oral or occlusal surface on demand. The great benefit of Vario-Tube in comparison with other methods is that it requires less material withdrawal, so it results in a more robust structure. There is no need to use an abutment, and yet its fitting precision is equivalent to ready-made abutments. There is no need to fix it with cement either, so you can avoid the unpleasant side eďŹ€ects of sub-gingival cement residues. Using this solution extends the capability of screw-retained Crowns and bridges even in cases of below-optimal implant positions. It also enables the dental restoration to be removable -in a non-destructive mannereven years later.
THE UNIVERSAL ABUTMENT AND THE ARCHED SCREWED CHANNEL Vario-Dock A or Vario-Dock B units are fixed into the implant platform, and then the threaded shaft is turned to the preferred angle of up to 25°, which equals the insertional angle of the denture structure. The remaining necessary axis correction (+0-25°) can be achieved by using Vario-Tube. With this combined solution, we can still produce a fully aesthetic, screwed and removable work even up to a 47-degree divergence.

It is perfectly applicable for all-on-4 hybrid prostheses and for any other screwed bridges where the axis divergence of the supporting implants require such a solution. Elsner System provides full interoperability between the various implant systems.
VARIO TUBE ARCHED SCREWDRIVER
The Vario-Dock Driver is a special tool which has been developed exclusively for Vario-Docks produced by Elsner System.
To use Elsner System's Vario-Tube, a special arched screwdriver is required, which is the proprietary development of the Elsner group. When inserting implants at an angle, it is a major technical challenge to tighten the screws with adequate force, as due to the tilted angle the head of a regular screwdriver will not make contact with the surfaces on all sides, meaning that if greater than necessary force is applied it can start free rotating and hence damage the screw.
The Vario-Dock Driver helps to insert, tighten and loosen Vario-Dock implants. It is placed on the Vario-Dock universal abutment, and then using the corresponding counter-part the adapter is fixed onto the Vario-Dock. The Vario-Dock can then be inserted easily. We recommend fastening it to the implant by using a force defined by the manufacturer. After loosening and removing the counter-part, the adapter head can be easily separated. The counter-part of the adapter can be used to position the threaded shaft, and this way the restoration can be easily placed.
To manage this problem the most suitable solution is to use a torx T6 screw and screwdriver. Thanks to its special design it can divert from the axis direction by up to 25Â°, and it can provide suitable rotating force even when screwing at an angle. When using such force as recommended by the manufacturer, screws can be tightened and loosened without being damaged, even in cases where high degree of axis divergence is present.
UNIVERSAL MOULDING HEAD The basis for high-precision dental technique is very accurate impressions and other registrations. These transmitting elements represent the information channel between dentist and dental technician. For this reason the accuracy of these elements is vital in order to avoid losing information and hence producing inadequate results. In implant prosthetics specially when utilising CAD-CAM systems, an even higher precision is demanded from both dentist and dental technician. The new impression coping system of Elsner System enables an outstanding accuracy in transferring data from mouth to cast and helps for dentists and dental technicians to prevent accuracy problems due to high degrees of axis divergence.
The geometrics of other manufacturerâ€™s coping heads donâ€™t always allow for their single, tension-free removal from the implants. Tensions arising during removal can result in malformed pressings. The advantage of universal impression coping heads compared to the traditional ones is that they are composed of two elements. The two separate parts are important so that the bottom part of the coping element (which connects to the implant platform) and the upper part (which is fixed into the impression) can be removed tension-free from the implant and from each other at the end of the impression process.

AXIS CORRECTION CASTING MOULDS There are several solutions at the disposal of dental technicians to build a superstructure, crown or bridge for a given assignment. These include using a moulding technique or CNC manufacturing. When using CNC technology, the screw channels - for example the tilted screw channels of Vario-Tube or Vario-Dock are built into the mould in the computer-aided planning phase. In the case of a traditional moulding technique, the technician forms the frames by using wax and moulding templates. With such systems so far only straight bore holes have been possible. Using Vario-Cast moulding templates, however, bore holes can be created at any preferred position or angle. When creating arched screw channels, the technician uses a screw to fix the main body of the multi-part moulding template into the corresponding shape of the gypsum sample. Then the sphere-formed elements are connected one by one, until they reach the required height and axis correction.
Vario-Cast (linear mould)
The above pictures show how to apply the casting moulds in case of arched moulds. This method can be used in any other types of moulds.
Vario-Cast Tube (arched mould)
If the embedded implant position and geometrics require using Vario-Dock, then the technician uses the axis-adjusted and properly-positioned Vario-Dock moulding form to match the Vario-Dock platform. Finally, the technician fixes it with the threading rod and female screw. If the angle-correction value is greater than 25°, then the 25° Vario-Dock main body is fixed onto the Vario-Dock platform, and then the process is continued with the same methodology as in the case of an arched borehole, so that an angle of up to a further 25° can be corrected. The result allows for shaping the tooth structure, and the replacement is ready for embedding and then moulding.
