AT THE FOREFRONT

Our aim is to achieve every time complete satisfaction for our clients, as we continuously explore new frontiers as far as new materials are concerned, testing their use to achieve the highest quality for our products. In order to maintain such standards, our staff regularly attend training courses. CLR makes use of all the latest scientific research evidence in the development of new manufacturing techniques.

3D Printers

3D printing concept is very similar to inkjet printing, even though the machine is far more complex. Printing software converts the STL file into a number of very thin layers (0,02 mm), made of the appropriate material, which are then printed and stacked on a plate. This system can not only be used to replace the traditional plaster items and for anatomical prototyped parts for surgical and academic use, but it is also used to produce the several templates required to develop the progressive orthodontic aligners technique (e.g. Invisalign).

Benchtop Scanner

With this system a model (plaster or other material), obtained from a traditional impression, is inserted into the scanner. Its advantage is that the dedicated software can extract a 3D model which can be stored and replicated numberless times without loosing any single detail. The technician will split the prosthetic model in several parts and scan them individually to achieve the highest level of accuracy. The concept behind the scanning process is very simple: the model is hit all around with light beams whilst micro-cameras record tilt, direction and distance from a reference point. The system is very similar to that used by radar, sonar and bats.

Dental C.N.C.

This is the most commonly used system in CAD designed prostheses manufacturing. With this technique the STL file is sent to a mill-controlling software, which then translates it in a series of movements for the milling tool. The prosthesis will be carved out from a solid block of the chosen material, held in place on a support plate. This is therefore a removing material prototyping process. The plate and the milling tool can move along various axes: their combined movement allows the reproduction of any CAD designed shape. Milling machines are solid and stable because they have to absorb significant vibrations, generated by the upper mill-holding head whilst operating. When working with particularly hard materials, with very high revs involved (over 20.000 rpm), lubricants must be applied to lubricate and cool both the milling tool and the milled piece.

Last Generation Software

CLR uses last generation software in the CAD designing process. This kind of tool has massively improved its capabilities through the years. Starting from a CT scanner or similar imaging device, today we can obtain an accurate 3D reproduction of cranial morphology. The use of the software allows to precisely define types, volumes, shapes and dimensions of connections. It also allows to reproduce virtually upper and lower arches, to simulate masticatory movements through a virtual articulator, and therefore crafting the prosthesis with CAM systems, stereolithografy or laser synthering, producing radiographic templates for the clinician, providing all tools for an implant supported prosthesis (templates and completed prosthesis), all this prior the actual surgery. These procedures are extremely complex, and at least for now they require expensive equipments and particularly highly skilled operators to be completed. However it is probable that in the next few years technological development will allow a wider audience of technicians to access, if not all of the system, at least a part of it, delegating to a few specialized centres the accomplishment of the most difficult and expensive technical steps.
