Sirona Inlab MC5 router and CAD/CAM technology

Over the course of 10 years of our work, we have managed to combine all existing modern trends in world dentistry in one network. Based on our experience, it was decided that the smile from the brand of the Sa-Nata clinic chain should be unique and created under the close supervision of our specialists. And also to be able to carefully and independently select all materials and equipment for the creation of orthopedic structures.

Therefore, “Sa-Nata” has its own digital dental laboratory “SA-NATA Dynasty”, which brings together the best team of dental technicians - true masters of their craft and artists. Properly selected innovative equipment of the modern world market also helps our technicians in the manufacture of orthopedic structures. One of our indispensable assistants is the German grinding milling machine Sirona Inlab MC5.

What is the Sirona Inlab MC5 for?

To create an individual orthopedic crown for the patient, a digital model of the crown is first designed in a special computer program. After the project is approved by specialists, the modeled crown is then sent for milling using the Sirona Inlab MC5 grinder. According to the previously created 3D model, the milling cutter cuts out the future crown from a special blank.

The functionality of the Sirona Inlab MC5 router fully meets the needs of the modern digital dental laboratory. With this grinder, we are able to process inlays, veneers, dental crowns made of zirconium dioxide or glass-ceramic. Sirona Inlab MC5 also mills abutments, bridges and even removable dentures.

What is the Sirona Inlab MC5 for?

The process of milling the future orthopedic structure occurs automatically. Using the Primescan Sirona 3-D scanner  and examination, all data about the individual structure of the patient's jaw and all other necessary parameters are collected. An individual project is created on the computer - a future orthopedic structure. Further, in the programs of the router, the necessary settings are set - tasks that are suitable for this particular modeled project of the crown. The most important parameters of milling modes (trajectory, diameter, speed, rotational speed) are calculated by a computer program. They largely depend on the type of material. After that, the milling cutter cuts out the future design from the workpiece.

Zirconia is processed by dry milling and then goes through the process of sintering (sintering) in a special furnace. And as a result, we get an almost ready-made crown, which remains only to be artistically decorated: to give it color and natural texture. Also, the Sirona Inlab MC5 router is used for milling temporary prosthetic structures. For such structures, wet milling is used, that is, with the use of water in the process.

The use of the Sirona Inlab MC5 grinding and milling machine in the process of creating prosthetic restorations in the laboratory has the advantage of accuracy and significantly reduces the production time.

All processes, from getting an outfit to trying on a finished orthopedic structure, are closely interconnected. One link cannot exist without the other. Therefore, when raising the issue of milling, it is impossible not to mention such modern technology as CAD / CAM technology for creating a crown.

CAD/CAM is a digital technique that automates the process of creating orthopedic structures. Thanks to CAD / CAM technology, the design is modeled in electronic format. In simple terms, prosthetics using CAD / CAM technology is computer modeling of the future design and computer-controlled production.

The manufacture of an orthopedic crown using CAD / CAM technology

The manufacture of an orthopedic crown using CAD / CAM technology takes place in 4 stages:

  1. Scanning the patient's oral cavity using the Primescan Dentspy Sirona intraoral scanner. The scanner reads the information of the site of future prosthetics and translates it into a digital model immediately on the screen.
  2. Modeling or project creation. Thanks to the obtained digital 3-D model on a computer, the specialist studies the model, selects options for prosthetics, corrects the shape of future crowns, their relief and wall thickness. At this stage, it is possible to compare the initial and intermediate simulated result with the patient and approve this project.
  3. Milling with the Sirona Inlab MC5 grinder. The created simulated model is transferred to the milling cutter, all settings and parameters are set, and the milling cutter processes the crown from the workpiece according to the parameters specified for it. Processing means by itself: turning, polishing and grinding the structure.
  4. The final stage: sintering (sintering) of the crown in a special oven, decoration by the technician and fitting of the finished structure by the patient.

Advantages of prosthetics using CAD/CAM technology:

Advantages of prosthetics using CAD/CAM technology:
  • Accuracy and perfection of final  result (perfect fit)

  • Faster fabrication term, as the number of necessary visits to the orthopedist is significantly reduced

  • The patient has the opportunity to independently observe the manufacturing process

  • Creation of orthopedic structures of any shape, complexity and from any type of material.

In the network of dental clinics, everything is thought out to the smallest detail, and most importantly, we constantly improve our knowledge and follow global innovations and trends! Absolutely every step we take in working with a patient is thought out and well-planned.

We wish each of you who wants to fulfill the dream of a cherished smile from the Sa-Nata brand to feel confident in the hands of true professionals in their field.
