What high-speed instruments are currently available on the market? What are the current trends in restoration and prosthetics and what future developments can be expected? The following sections provide information that will assist you in the fast and correct selection of the right dental handpieces for you.
Dental handpieces such as contra-angle handpieces and turbines are now viewed as more than simply “commodity products”. However, the information below makes it clear that this view is not adequate. Dental handpieces are among the most important tools for dentists and form an important part of every modern dental practice.
Air systems vs electrical systems
There are two systems for powering burs: air and electrical. In the air system a distinction is made between a turbine and an air motor.
In the air system a distinction is made between a turbine and an air motor. With turbines the bur is directly driven by a rotor. The rotor has an impeller powered by compressed air. Turbines reach an idle speed of up to 400,000 min-1. The working speed depends on the pressure exerted and is approximately half the idle speed - i.e. approx. 150,000 to 250,000 min-1. The maximum power of 10-26 W is also reached in this speed range.
The air motor drives the bur indirectly via a contra-angle handpiece or straight handpiece. It reaches a maximum speed of 25,000 min-1. Contra-angle handpieces are available in various step-up and step-down ratios. An air motor with a 2:1 contra-angle handpiece step-down ratio thus reaches a speed of approx. 12,500 min-1.
Electric motors reach an idle speed of up to 40,000 min-1. This corresponds to a bur speed of 200,000 min-1 for 1:5 contra-angle handpieces. The maximum power is over 60 W and the torque is approx. 3 Ncm. This means that electrically powered contra-angle handpieces are not slowed or stopped when the bur cuts through different tooth structures or prosthetic materials. They continue cutting at virtually constant speed regardless of the load. Compared to turbines, burs are much more stable with contra-angle handpieces. Burs in a contra-angle handpiece vibrate much less than with turbines. Improved stabilization means greater precision, faster work and less heating of the tooth substance during preparation.
The trend towards electric motors was first noticed in Europe. One important reason for this was the potential expense of installing new air lines in existing buildings. It also became obvious that electric drives are not only easier to install but are also more efficient in use. Now, some decades later, electric motors have become very popular in both Europe and Asia. Innovative developments in the fields of design, materials, torque and light are now also contributing to the popularity of electric motors in North America. They make work in the dental practice faster and easier.
The currently available range of straight and contra-angle handpieces includes the right instrument for every requirement. Most manufacturers offer products suitable for a wide range of applications and also products for highly specialized clinical applications.

Where To Find a Excellent Dentists?
A smile on a person’s face is one of the most noticeable things known to create a first and last impression on others. Let your smile be the signature of your personality even if you are not lucky enough to have extraordinarily sharp and adorable facial features. As Thich Nhat Hanh stated “Sometimes your joy is the source of your smile, but sometimes your smile can be the source of your joy”. So let your charming smile be a reason for the healthy joy that is best reflected with a pearly white shine of your teeth.
Things to look for to find a good dentist in your area
Experience – It is very important to consult a dentist who has several years of experience in the field of dentistry. The more the experience of a practitioner, the better are the chances to get clean and professional dental services.
Education – Look for an educated professional who is well-trained to carry on the dental procedures easily. It is also very important to look for someone, who is knowledgeable and stay informed with the ever changing dental technology and understands the novel approaches made to the technology.
Access to dental equipments – A good dentist must have access to all the latest tools required to carry on the dental procedures.
Sterilization – It is really important to ask for the sterilization process that a dentist makes use of. The best way is to look for the requirements for the sterilization procedures online and make your decision.
Reputation – Seek for a practitioner who holds a good reputation in your town. When it comes to reputation, it is important to research on the reviews other people have to give about their services. Speaking to friends, neighbors and family members will certainly help to let you know about the reputation of a dentist you are planning to see in the near future.
The other thing to think about is what the dentists primary goals are? Does he or she consult their patients on hwo to protect their teeth and what they can do to prevent cavities? Do they celebrate with you when you have gone another year without problems? Do they do whatever they can to help you prevent problems? Good dentists do not want you to have teeth problems and will be genuenly sorry when you do have issues that show up. So pay attention to their attitude toward dental issues or the lack of dental issues.
Last of all I would pay attention to the dentists prices for check-ups, major procedures, or other dental needs. Good dentists will not be looking to price gouge you but instead will try to work with you in getting you a good price. Dentists have to be able to cover their expenses but not in one fatal swoop. Dentists buy dental equipment like marathon micro motor from internet.
These are just a few ideas I have on how to pick a good dentist but if you follow these steps you should have much better luck than my grandma did in picking a dentist that not only does great work but is also honest and fair in price.
