Best Dental Lab Scanners (Review)

Modern dental treatment and prosthetics is significantly different from what it was a decade ago. Every year, new medicines and better filling materials appear. Also, the methods of making all kinds of dental structures – crowns, prostheses, bridges, aligners, etc., are being improved.

With the development of computer technology, dentists can significantly improve the quality of their services by applying the latest developments in this area. In particular, we are talking about the introduction of 3D modeling into the treatment process.

CAD/CAM technology is widely used in a variety of fields, from engineering to jewelry, design to medicine.

This abbreviation means the following:

• CAD – Computer-Aided Design (application of computer design).
• CAM stands for Computer-Aided Manufacturing.

The method of creating a future prosthesis (crown, bridge, etc.) based on a 3D model is becoming more popular. With time, it is displacing the manual method of manufacturing. And this is not surprising, since it is much more accurate, faster and produces high quality results.

CAD/CAM systems can work with various materials. The systems work with well-known ceramics, zirconium and aluminum dioxide, titanium, steel, metal alloys and even plastics.

The dental CAD process includes several phases:

1. Scanning the patient’s oral cavity.
2. Processing the resulting 3D model using a special program.
3. Sending data to a CNC machine with subsequent automatic turning of the desired product.

Dental crowns and prostheses made in this way are more comfortable and perfect than those made using the casting method. CAD crowns and prostheses are made taking into account the unique characteristics of the client: the structure of the jaw, the position of the teeth, their anatomical shape, size, etc. These characteristics were difficult to achieve earlier.

In addition, dental CAD procedures takes less time. The patient literally has to go for a single visit to the dental lab. There is no the inconvenient procedure of taking teeth impressions. With CAD/CAM technology, this function is done by an intraoral 3D scanner. This is great for many patients as it eliminates the need for taking multiple impressions, which could cause severe discomfort.

In addition, patients don’t have to wait several days for the dental technician to make the crowns or walk with the prepared teeth, which is unpleasant.

Automatic tuning of crowns based on a computer 3D model helps to prevent inaccuracies in manufacturing, deformations, shrinkage after, and similar problems. The CAD program calculates the necessary parameters for the operation of an electronic router and does it flawlessly. The result is an exact product (in shape, color, size and proportions) that is ideal for the patient. The dentist does not have to adjust and alter something, as it was the case before.

Computer modeling helps to create anatomically accurate models of dentures, crowns, etc., as well as predict their further use.

Often, in addition to the abbreviation CAD/CAM, you can see another one – CAE (Computer-Aided Engineering). This refers to a product engineering analysis program that allows you to assess the reliability of a structure under load.

In any case, using a 3D model is the most technically advanced way to create an anatomically suitable prosthesis that modern dentistry has to offer. Intraoral and laboratory 3D scanners are indispensable tools for its implementation.

Intraoral Scanners

You need to use a 3D scanner to create a 3D model of the dentition. Data can be “removed” both from ready-made impressions (laboratory scanners), and directly from the patient’s oral cavity. The latter option is preferred, unless there are any difficulties with the passage of the beam i.e., hard-to-reach places.

Creating dental 3D models is done with the help of intraoral 3D scanners. The equipment help to determine the necessary measurements for building a 3D model in minutes. The procedure is painless as the person is not exposed to any unpleasant influences .

Before the introduction of intraoral scanners in dentistry, dental impressions were made using a solidifying plastic mass, which was inconveniencing to most patients. In addition, in the future, the plastic mass could shrink a little and deform. This affected the accuracy of the reproduction of dentures.

Traditionally casted teeth molds had to be tried on and adjusted several times. However, 3D scanning, allows you to get the most detailed digital impression without any distortion.

Initially, all intraoral scanners were only compatible with milling machines of the same brand. Today, the 3D scans taken using intraoral scanners can be used on any device. Therefore, you can select different equipment for both scanning and manufacturing future crowns.

How Do Intraoral Scanners Work?

Intraoral scanners are compact and light in weight. They are also easy to use, despite all their technical complexity.

With the equipment, the dentist directs a beam of light to each tooth (or the part of the jaw that is needed). That reflecting transmits the data to the monitor screen, where a 3D image is built in real time. The transformation of a streaming signal into a picture occurs thanks to special software, which first builds a point cloud based on the received data, and then creates a 3D model from them.

The advantages of such an image are also that it can be controlled. You can control the detail, twist it in different directions, modify it, highlight individual parts, etc. This greatly facilitates the task of specialists, allowing them to quickly create the desired structure and send it to work. As a result, on the second visit, the client will be able to get what he came for.

Intraoral scanners are useful not only for orthopedic surgeons, but also surgeons, orthodontists, and therapists. Based on the 3D image obtained, you can make inlays, crowns, bridges, prostheses, aligners, perform high-quality restorations, install veneers, etc.

Dental Lab 3D Scanners

In addition to intraoral 3D scanners, there are also laboratory scanners. These dental 3D scanners take pictures not from a patient, but in a dental laboratory, by scanning a plaster impression made in a standard way.

With the help of directional structured light, the scanner collects a point cloud (the coordinates of an object in space) and builds a 3D model based on it. The device does this automatically without human intervention. Special software analyzes the information received and creates a digital image on the monitor screen.

This scanning method is highly accurate. In this case, the conditions are quite favorable: good lighting, full access to all parts of the object, and its immobility. As a result, the quality of the images is excellent. Every detail is conveyed without distortion.

However, plaster casts do not provide information about the real color of the teeth. Therefore, the doctor will select the desired color and shade of the prosthesis or restoration. However, most laboratory 3D scanners have functions that allow you to color correct the image. There are also options for “refining” a 3D model based on the task at hand.

Best Laboratory 3D Scanners

Should You Buy a Dental 3D Scanner?

Modern technologies greatly facilitate and simplify various processes in dentistry. Crowns, bridges, prostheses and other dental structures created with a 3D scanner are more accurately than those made by taking impressions.

Sooner or later, the old ways of taking dental impressions while phase out. If you want to keep up with the times and retain customers’ trust, embrace technological developments. This will help you to be competitive and improve the quality of your services.

Laboratory and intraoral scanners make dentistry work more comfortable and efficient. 3D modeling allows you to carry out various manipulations with the resulting model to get the perfect model that does not have to be redone later. This saves you and your patients both time and money.
