3. INTRODUCTION
Dental drill is a small, high-speed drill used during dental procedures, usually to remove decay
and shape tooth structure prior to the
The dental drill is one of the most present and important instruments - for the dentist as well as
for the patient.
Most of the drilling tools used by the dentist are transition metal carbides tipped.
Carbides are characterized by their high hardness and strength, which have a beneficial effect
for the abrasive properties of the driller.
This reinforcement of blanks is essential with cutting forces of 0.5–2.0 N and tool speed of
2000–250,000 rpm.

4. REVIEW OF LITERATURE
 A dental drill or handpiece is a hand-held, mechanical instrument used to perform a variety
of common dental procedures, including removing decay, polishing fillings, performing
cosmetic dentistry, and altering prostheses.
 The electric drill, is not quite as powerful, but still works great and has its own benefits.
 The electric dental drill, also known as an increasing-speed drill, is powered by an electric
motor called a micromotor.
 Inside the handpiece are internal gearings which allow the friction grip burr (also used
with the turbine powered drill) to rotate at a constant speed, independent of torque.
 This means the power is provided by the internal motor and the gears inside. As far as how
it feels in the hand, the end of the drill with the motor in it tends to be a bit heavier.
 Some dentists prefer this feeling, some prefer the more evenly-distributed feel of the
turbine-powered drill.
 This drill also doesn’t get as hot as the turbine-powered drill, lessening the amount of extra
gadgets required to use it.

Advantages of Dental Driller
Disadvantages of Dental Driller
• You have to make the template by hand.
• The drilling guide may be imprecise due to deviations caused by manual production.
• More mess is made due to the grinding dust.
• High speed
• High output
• Easy to operate
• High flexibility
• Low maintenance and lower cost

6. TYPES OF AVAILBLE DEVICE IN THE MARKET
There are two kinds of dental drills most commonly used:
1. Electric Dental Driller 2. Turbine powered Dental Driller

7. 7 Here's a basic breakdown of the most common types of handpieces
and how they're being used today.
• High-speed (air-turbine) handpiece.
• Low-speed (air-turbine) handpiece.
• Electric handpieces.
• Surgical handpieces.
• Endodontic handpieces.
• Implant handpieces.

10. WORKING OF DENTAL DRILLER

• Dental burs (drills) are more than capable of cutting into healthy
teeth. Although the goal is to remove carious dentin (base under the
enamel), which is soft, you must cut through healthy tooth structure
to get at it, and to prepare the proper shape of cavity preparation to
place and retain the filling.
• The early burs were about 12 inches long, made of tool steel, and
were rotated by hand with a small bow; the RPMs were about 120. It
was very slow going through enamel, but better in dentin.
• Hand instruments shaped like chisels did a lot of the finishing of the
cavity preparation.Hand pieces were developed that accepted shorter
steel burs and were powered with foot pumps, getting RPMs up to
500.

11. 11
• The foot pump was replaced with electric motors and RPMs shot up
to 3,000 with tool steel burs.In the early 1940s, pulley wheels were
used to move the RPMs up to 10,000, still with tool steel.
• They got hot, and air and water spray had to be added.
• This generates a huge amount of heat, so high-speed devices are
also connected to a cooling water supply.
• New technologies in development – including laser and air-abrasion
drills – are hoping to improve the experience of going to the dentist
by providing drills that remove decay without generating the heat,
noise and vibrations associated with their predecessors.
