Computer technology CAD / CAM for making the perfect crown

Computer technology CAD / CAM for making the perfect crown

All processes in the manufacture of individual orthopedic crown are closely related. One link cannot exist without the other. Modern approach in the manufacture of high-quality, accurate and super-functional orthopedic crown today is impossible to imagine without CAD/CAM technology.

CAD/CAM is a digital technique that automates the creation of orthopedic structures. Thanks to CAD/CAM technology, the design is modelled in electronic format. In simple terms, prosthetic CAD/CAM technology is computer simulation of the future design and its production carried out under the control of a computer.

The abbreviation CAD/CAM stands for:

  • CAD - Computer-Aided Design (Computer Engineering)
  • CAM - Computer-Aided Manufacturing (Computer Manufacturing)

Innovative system of dental prosthetics CAD-CAM is actively applied in clinic "Sa-Nata", and more precisely - in our digital dental laboratory «Sa-Natа Dynasty». CAD/CAM system is based on the use of computer technologies for automated digital design, modeling and production of various orthodontic structures such as crowns, bridges, veneers, as well as skeletons for removable and fixed dental prostheses.

One of the main advantages of the CAD-CAM system in dentistry is the avoidance of human error, as the entire process of design and production is controlled by the computer. This makes it possible to achieve a more accurate and predictable result and to reduce the risk of errors that may occur in traditional prosthetic methods

The abbreviation CAD/CAM stands for:

In addition, the CAD-CAM system allows more efficient use of materials, as it optimizes the cutting process and minimizes waste. It also provides faster and more accurate production of prostheses, which reduces the time required to complete prosthetic procedures.

Manufacturing of orthopedic crown by CAD/CAM technology takes place in 4 stages:

Manufacturing of orthopedic crown by CAD/CAM technology takes place in 4 stages:
  1. Oral cavity scanning using the intraoral scanner Primescan Dentspy Sirona. The scanner reads information about the area of future prosthetics and translates it into a digital model.
  2. Creation of the project. Thanks to the resulting 3-D digital model on the computer, the specialist studies the model, selects options for prosthetics, adjusts the shape of future crowns, their relief and wall thickness. At this stage, it is possible to compare the baseline and the intermediate output and approve the project. This digital tooth model becomes the basis for crown design.
  1. Milling with Sirona Inlab MC5 grinder. The created model is transferred to the milling machine, all settings and parameters are set, and the milling machine processes the crown from the workpiece according to the parameters set by it. Machining includes: weathering, polishing and polishing the structure.
  2. Sintering (synterization) of the crown in a special oven. The preliminary form of the crown is placed in a special furnace, where it is synterized. During the heating process, the material becomes more dense and durable, as well as acquiring the required optical properties such as color and transparency.
  1. Final finish After creating a crown using CAM/CAM technology, it undergoes final finishing to give it a precise shape, tint matching the patient’s natural tooth. This may include painting, enameling and polishing to achieve the most realistic look possible. After the completion of this stage, the fitting and fixing of the finished crown is carried out.

CAD-CAM technology in dentistry allows you to create different types of crowns, including:

CAD-CAM technology in dentistry allows you to create different types of crowns, including:
  1. Temporary crowns. They are used as a temporary solution, for example, during the process of making permanent crowns. Temporary crowns can be made of temporary materials such as acrylic or composite using CAD-CAM technology. They are usually used to protect the tooth from damage and maintain aesthetics until a permanent crown is made.

  2. Permanent single crowns. Single crowns used to restore one tooth can be made using CAD-CAM technology. The dentist designs the shape and size of the crown on the computer using the program, and then the machine grinds the crown from selected dental material such as ceramics or zirconium.

  1. Bridge crowns. Bridge crowns used to replace one or more missing teeth can also be made using CAD-CAM technology. The dentist designs the bridge structure on the computer, including supports and dental replacement. The machine then grinds the crown from the selected dental material.

  2. Telescopic crowns for dentures. Telescopic crowns used in dentures can also be made using CAD-CAM technology. The dentist designs the crown on the computer taking into account the peculiarities of the bruising design, and then it is milled on the machine from the appropriate dental material.

Advantages of CAD/CAM crown:

Advantages of CAD/CAM crown:
  1. High precision and detail. Using CAD-CAM technology allows you to create crowns with high precision and detail. Computer simulation allows accurate determination of the shape, size and contact points of the crown, which provides a more accurate match to the anatomy of the patient’s tooth and bite.
  2. More predictable manufacturing process. The use of CAD-CAM technology allows dentists to control more accurately the process of making crowns. The software allows to visualize and optimize the design of the crown before its manufacture, which reduces the possibility of errors and inconsistencies
  1. Speed and efficiency. Making dental crowns using CAD-CAM technology can be faster and more efficient than conventional methods. Crowns can be made on machines in a relatively short time, which allows you to reduce patient waiting time and simplify the dental process.
  2. High quality and durability. CAD-CAM crowns can have high quality and durability. The use of high-quality dental materials and precision milling allows you to create crowns with excellent fit and durability.
  1. Aesthetic characteristics. CAD-CAM technology also allows dentists to achieve a high level of aesthetics in crowns. CAD software allows you to visualize and optimize the aesthetic aspects of the crown, such as shape, color and texture, allowing you to achieve a natural and attractive appearance.
  2. Individualization. Individualization is one of the important advantages of dental crowns made with CAD-CAM technology. CAD software allows dentists to carefully design crowns taking into account the anatomical features of the tooth and bite of the patient, as well as the possibility of creating crowns with individual aesthetic characteristics. Using CAD-CAM technology, dentists can visualize and optimize the shape, size, contact points, color and texture of the crown to best match the anatomy and aesthetics of the patient’s other teeth.
  1. Functionality. Using CAD-CAM technology it is also possible to create crowns taking into account the functional features of the patient’s teeth, such as bite, occlusion and articulation. This makes it possible to achieve optimal crown planting and functional efficiency, which is an important aspect in the long-term successful operation of crowns.

Digital dentistry really revolutionized the process of making dentures. With the use of computer technology, the manufacturing process became more accurate, fast and convenient for patients.

One of the main advantages of digital dentistry is the ability to manufacture dentures in one day. Previously, patients had to wait several days or even weeks to get their prosthetic design ready. Now, thanks to automated processes, the physician can take measurements and simulations in a single session and then send the data to the lab to make the prosthesis. The prosthesis can then be installed on the same day, reducing the patient’s waiting time.

Digital dentistry also allows more accurate modelling of dental structures. Using computer technology, a doctor can create a digital model of dental design, which reduces the probability of errors and inconsistencies. It also allows the patient to see a virtual image of their future prosthesis, which helps to better visualize the result and make adjustments before making a real design.

Another important aspect of digital dentistry is the ability to use various materials, such as ceramics, titanium, zirconium and others, to make dentures. This allows you to choose the most suitable material depending on the needs of the patient, which gives more flexibility and quality in the manufacture of prostheses.

However, despite all the advantages of digital dentistry, it is important to note that it is not a universal solution for all cases and requires certain technical knowledge and equipment. Each case is individual, and the choice of dental design method must be based on a professional assessment of the dentist and the patient’s needs.
