As we already know, ultrasonic devices are used in endodontics and periodontics for the removal of subgingival and supragingival plaque, the cleaning of tartar and surface stains, as well as in the surgical process. Years ago these procedures were performed manually with instruments such as curettes, sickles or chisels, which required much more effort for clinicians and stress for the patients, hence favouring a progressive switch to mechanical instruments.
However, It is important to consider, that before choosing our ultrasonic devices, we become familiar with their technical specifications. For this reason, at Dentaltix we offer this guide with the most important points to consider when choosing the one that suits you best. We also remind you that in case of any doubt it is essential to contact your distributor as he is the most qualified person to advise you and describe in details its operation, technical characteristics and its compatibility with different tips.
How do ultrasonic machines work?
Ultrasonic devices work due to a transmitter that generates ultrasonic waves. These ultrasonic transducers are made of piezoelectric materials (quartz crystals and tourmaline), that is materials that generate electricity by deformation, which when compressed and returned to their initial form, convert electrical energy into mechanical energy and vice versa.
What are the 5 variables that you look at or should look at when choosing an ultrasound?
- Price
- Durability
- Performance
- Design
- After-Sales Service
Main features:
But as with all products, the most important thing is without a doubt the features and specifications that each ultrasound offers you:
- Ultrasound devices can have up to a maximum of 3 functions: Prophylaxis, periodontics and endodontics.
- They can have LED light or not.
- You have to look at whether the handpiece is removable or not.
- Very important is the compatibility and type of connection of the handpiece (Satelec or EMS).
- Not all ultrasound devices have autonomous water supply, it is important to check if it has one or not, as it makes it easier to move the unit from one cabinet to another. another.
Technical features to take into account for an ultrasonic scaler
A) Handpiece
The handpiece is a fundamental element in an ultrasound device as it is essential that it is compatible with the tips we use. As we already know, these components work directly in the patient's mouth so it is important that they are self-cleaning at a temperature of 135 º C for proper disinfection.
Two other relevant aspects related to handpieces are their frequency and amplitude. For good cavitation, the frequency must be between 21-32 kHz. However, the frequency does not directly determine the effectiveness of cavitation as other technical factors such as correct adjustment and screwing to transmit the appropriate vibrations have an influence. The amplitude of vibration, on the other hand, depends on the shape of the tip. Therefore, when we have to remove large quantities of tartar, we obtain better results with a wide tip than with a fine one. For this reason, it is recommended that our ultrasound kit has a wide enough range of tips to perform our work efficiently.
B) Ultrasonic tips
Ultrasonic tips, also known as inserts, are paired with each ultrasonic device, so generally each manufacturer produces and recommends their own tips. The DTE brand however has released some ultrasonic equipment compatible with tips from other manufacturers such as Satelec, the world leader in ultrasonic equipment. Nevertheless, we must take into account that when selecting one specific brand from the market, we will automatically be choosing tips from that same manufacturer. Therefore it is vital that we inform ourselves of the prices and features (size, material etc.) that a brand has to offer before purchasing our ultrasonic device.
Division of ultrasonic devices
- Integrated in the dental chair. When we buy this type of ultrasonic equipment we must be aware that it is going to be integrated into the dental chair forever. One of the advantages of this is that it will be cheaper; on the other hand, we won't be able to perform certain treatments such as those in periodontics given that it will not be possible to supply any liquid to the patient, with the exception of water, through the dental unit. To provide a solution to this type of setback, we also recommend this DTE scaler integrated in the dental unit and available at a very low price.
- Independent without water tank. This type of ultrasonic equipment always needs to be connected to a water source whether it be the water supply from the dental chair or an external tank. Just like the devices integrated in the dental unit, these aren’t suitable for performing treatments that require other liquids than water. However, the most modern versions of these devices include various functions that can be of great help. Here we recommend you the DTE Ultrasonic D5, which comes with built-in LED for a clear and sharp vision.
- Independent with deposit. These devices can operate completely autonomously because they do not need to be connected to a water source. Thanks to this, the device can be transported from one place to another in a comfortable way. They are also suitable for periodontal treatments. We advise you to have a look at the Ultrasound DTE D7 which works independently and contains 6 tips.
