Advantages of CAD/CAM Porcelain Restorations (CEREC, Inlab) At Lan Anh Dental Clinic

  • 26/08/2022
  • CAD/CAM porcelain restorations have become very popular today, and have also demonstrated its superior features. At Lan Anh dental clinic, we use the CEREC and Inlab porcelain restoration system of Sirona company (Germany).

    Sirona Dental System Inc. (Germany) is world famous for manufacturing CAD/CAM porcelain restorations, because this system has outstanding advantages compared to some other brands.

    1) Computerized design:

    Today, most design work is done on computers. So is the design of porcelain restorations. Computerized design makes the work much more convenient and faster than traditional manual molding techniques.

    Design CAD/CAM CEREC porcelain restorations. The doctor uses the Omnicam camera system to scan the image on the patient's mouth, then back it up to the computer and design the porcelain restorations on the computer. If using the Inlab system, the doctor will take an impression to make a sample of the patient's jaw.

    The difference between Sirona's CAD/CAM CEREC and Inlab systems is convenience, speed and very high accuracy. With CEREC, your dentist can design your porcelain restorations in minutes, and produce porcelain restorations from the whole porcelain block in 10 minutes. If you are not satisfied because porcelain restorations are not beautiful, then just a few minutes later, there will be another porcelain tooth. This is really different. Before, you would have to wait 1-2 days for another porcelain tooth to be produced if you are not satisfied. Today, at Lan Anh dental clinic, with the CEREC system, the doctor can design and make the porcelain tooth that you like very quickly.

    Design porcelain restorations from your chosen porcelain block

    Insert the porcelain block into the machine, and the porcelain block will be "cut" according to the design on the computer. With the CEREC system, the whole process takes only about 45 minutes.

    2) Precision and good fit with real teeth:

    In the past, technicians doing manual techniques to make porcelain restorations will easily encounter the situation where the porcelain crowns do not fit the real teeth and make the porcelain restorations open. Bacteria and food plaque will be crammed in these openings, quickly damaging the "real tooth", damaging the real tooth inside. This condition can cause real teeth to be so damaged that they cannot be kept and must be extracted.

    Porcelain restorations are exposed on the inside. This open area will be a place for bacteria to live, stuffing food and damaging real teeth inside.

    Porcelain restorations are exposed after a period of use. Bacteria accumulate causes gingivitis, damaging the real teeth inside. In this case, the gap is quite large because the porcelain restorations do not come down close to the real teeth (the protrusion is higher than the adjacent teeth).
     

    Porcelain restorations exposed on x-ray film. For porcelain restorations that have undergone root canal treatment, the patient does not have a feeling of sensitivity, pain and does not know that the real tooth is damaged, until the root area is infected, or the tooth is loose.

    For CAD/CAM porcelain restorations, this situation is minimized, because on a computer, doctors or technicians can "zoom in" and carefully design the junction between real teeth and porcelain restorations to ensure tight fit.
     

    When designing porcelain restorations on a computer, the doctor can "zoom in the porcelain restorations", adjust the contact area between the porcelain restorations and the real teeth precisely. In addition, other points which are also very important such as the thickness of the porcelain restorations (to avoid broken porcelain), contact with the opposite teeth (for good chewing function), contact with adjacent teeth (to avoid stuffing). food interstitial), etc. are meticulously designed with high accuracy. 

    With CEREC porcelain restorations, you can be completely assured because the doctor is the one who directly designs your porcelain restorations. In addition, the CEREC machine scans the sample directly on the mouth (not through the jaw model) so the accuracy is almost absolute.

    CEREC Omnicam system. This system is very popular in developed countries for porcelain restorations such as the US, Europe, etc.

    Using the CEREC Omnicam system, doctors scan images directly from the patient's mouth and design porcelain restorations on a computer. Then, the machine will cut from the porcelain blocks to create the porcelain crown/veneer according to the design.

    3) Flexibility when using materials to make porcelain restorations:

    Every patient is unique, and so are their teeth.

    Each patient has a different smile, a different tooth color requirement, a different tooth shape. Therefore, it is necessary to have many porcelain systems with many teeth colors, types, etc. to be able to make a "best" porcelain crown.

    Therefore, if you want to have a real porcelain restoration, the doctor needs to have many different porcelain material systems.

    Thus, if you have porcelain restorations with only one type of material (such as Zirconia or Cercon) for all cases, there will be times when the results are not really the best.

    The Inlab and CEREC CAD/CAM systems are designed to be able to choose from a wide variety of ceramic materials. This is very important, as it will meet the needs of doctors and patients for many different cases.

    4) Quick working time:

    When the real tooth is milled, it will be in a sensitive state and easily affect the tooth pulp. Therefore, porcelain restorations finished quickly and attached early in the day will limit this situation, the possibility of affecting the tooth pulp is minimized.

    When designing CAD/CAM porcelain restorations, all you need is a powerful computer. 

    When you make many porcelain restorations at the same time, the CAD/CAM computerized design and simulation helps to control the general condition of the bite and each tooth much better.

    5) Slim and delicate:

    For porcelain-fused-to-metal restorations and Zirconia restorations, the technician needs to make a "framework of porcelain restorations" and then put porcelain restorations on it. This requires the real tooth to be milled a lot to make room for the frame and porcelain.

    For CEREC porcelain restorations, the porcelain is cut from the porcelain block, so the maximum thinness can be achieved. There are cases of minimally invasive porcelain restorations, the doctor only needs to mill 0.5 - 0.8mm real teeth to make bridges, veneers, lumineers, etc.

    The result is highly aesthetic. Today, the thinner porcelain restorations, the more real teeth are preserved, the more durable and beautiful they are, because real teeth are the best, which should be preserved as much as possible.

    At Lan Anh dental clinic, the CEREC porcelain system can design and make veneers and crowns much thinner than usual, about 0.5 - 1 mm depending on the case.

    6) Durable, beautiful and sturdy:

    Because CEREC porcelain restorations are designed and cut from porcelain blocks, their durability is very high. CEREC porcelain restorations can be cut monolithically, or covered very little (to achieve aesthetics) so they are rarely broken when patients chew. 

    7) Reliability in quality and materials:

    At Lan Anh dental clinic, you can visit the porcelain dental lab at any time and watch the technician design and make your porcelain restorations. 

    With CEREC porcelain restorations, you can completely open the sealed box of porcelain blocks from the manufacturer, touch the porcelain blocks, and monitor the process of cutting porcelain restorations. Thus, you can be assured of the quality of the material.

    8) Optimal aesthetics:

    When doing cosmetic porcelain restorations, you hope your teeth to be exactly what you want: both in terms of tooth shape and color. Sometimes it is necessary to make several sets of porcelain restorations with different colors and shapes to meet your needs. This is very difficult to do with handmade porcelain restorations. In addition, the risk of broken porcelain restorations will increase if porcelain restorations are repaired many times.

    Due to the fast design and construction time, CEREC porcelain restorations can meet this requirement. If you are not satisfied with the shape, the doctor just needs to correct it by "clicking". What if you are not satisfied with the color? The doctor also only needs to choose a different porcelain block. More importantly, each of your porcelain restorations is cut from a new porcelain block, completely "brand new", without worrying about the durability of porcelain restorations being affected when repaired many times.
     

    CEREC porcelain restorations at Lan Anh dental clinic are very diverse in color, and high in thinness, helping to prevent the porcelain restorations from being "rough", the color meets the requirements of the patient.

    Conclusion: With today's modern CAD/CAM technology, porcelain restorations have been greatly improved in quality. The variety of colors, tooth shapes, and durability is further improved with the "monolithic cut" porcelain system. In addition, the trend of "maximum conservation", or "minimum grinding" is also widely used in CAD/CAM systems, especially CEREC, to help patients get satisfactory porcelain restorations.
