Straight handpieces are one of the most commonly used instruments in dentistry. This is why, at Dentaltix, we want to help you choose the one that best suits your dental practice needs.
Before going into too much details we should acknowledge that the straight handpiece, is a low speed rotary instrument, which can go from 20,000 to 40,000 rpm. You should also know that this instrument is not usually used inside the mouth as its most widespread use is to touch up the prosthesis, and lastly that it is always attached to a micromotor.
What to consider when picking a straight handpiece?
When choosing to buy a straight handpiece, we must consider 4 important features:
- The type of propulsion: air or electric
- Lighting: with or without light
- The size of the head
- Cleaning and maintenance
Types of propulsion in straight handpieces
Air propulsion: The air micromotor drives the handpiece, transmitting the power through a rotor onto which the compressed air acts. These propulsion systems reach a maximum speed of 25,000 rpm.
Electric propulsion: Electric micromotors achieve an idle speed of up to 40,000 rpm and, unlike air motors, they maintain an almost constant speed independently of the load. This ensures that the cutting speed is not reduced during preparation processes when the drill comes into contact with the tooth structure or the prosthesis.
Straight handpieces: with or without light?
In any dental work, excellent lighting in the treatment area is more than necessary. As a result, since 2007, some instruments have incorporated the use of LEDs, which has proved to be a great advancement in the dental sector. Light handpieces are usually less economical than those without illumination, but they do make the dentist's work much easier.
At Dentaltix we would advise you to purchase a straight handpiece that includes an LED light, and one of our recommendations for this is the DPS line straight handpiece with light.
The size of the head
This is a very important point as the types of treatments and connections to the burs will depend on this. Straight handpieces have a specific connection with the head, and burs from other rotary instruments such as turbines or contra-angle handpieces may not be compatible with the handpiece.
On the other hand, the smaller heads will offer better access and greater visibility in the operating field. When making the purchase decision, it is important that you consider the height needed for the work, i.e., the height of the head plus the height of the cutter. If you work in pediatric dentistry, you will need to work with small instruments.
Cleaning and maintenance
Never forget the cleanliness! To meet all hygiene requirements, handpieces, turbines and motors must be sterilized after each use on a patient. For this reason, it is very important that the instruments can be quickly separated from each other, so that the dentist does not waste unnecessary time doing this and can devote it to the management of the dental clinic.
To extend the service life of your handpiece, it is advisable that the sterilization process does not exceed the maximum permissible temperatures. The best choice for this is a professional class B autoclave, as they treat the material carefully and effectively. Some time ago at Dentaltix, we gave you some guidelines on how to choose the best class B autoclave.
We hope that all these tips will help you in the task of choosing the ideal handpiece. You have our catalogue at your diposal with a wide variety of straight handpieces, and we are certain that you will find a handpiece that suits both your needs and budget in it.
