Benefits of Laboratory utilization

  • Laboratory Utilization

A dental handpiece has a wide array of benefits. One of the key benefits is performing heavy-duty grinding and adjustment for different types of restoratives. The basic purpose is to prepare restoration before delivery. Thus, these use the superfluous material to give the oral cavity

  • Use in Dental practices

The handpiece has wide use in the dental field. When the dentist receives their equipment they first have to calibrate it or do minor adjustments to do dental procedures with the new restorative device. The dental lab handpiece is beneficial for polishing as well as the trimming of the porcelain, metal, composites, and acrylic dentures. Because of their easy usage, these handpieces have helped the dentist to fit the tooth or do oral procedures conveniently. Through these modern pieces, the dentist can now do major as well as simple adjustments smoothly and correctly.

Features of the Handpiece

 

The electronic handpiece is a high-performance desktop device having a reliable low speed and consistent torque. These are thin, short, and lightweight devices to use in both vertical or horizontal position. The device has an ergonomic design, low level of noise, durable and low vibration. Thus it offers the optimal performance.

How the Dentist Chooses the Dental Handpiece?

 

To choose the appropriate handpiece for dental procedures dentists have to consider the following factors. These include

Making List

First, it is important to make a checklist of handpieces. These are mainly used n tooth preparation with low-speed models suitable for finishing and polishing tasks. Moreover, there are available pieces that do not work effectively at both low and high speeds. So to find the right model it is important to make a list to get the appropriate one to perform functions in the best way.

Hand of Operator

The other factor to consider is the hand of the operator. It is essential to find the equipment that comes with proper weight and balance as well as has feel and performance. One has to determine the weight and balance as well as performance to have a comfortable operation. There is a need to determine the quality to ensure the maximum benefit from it.

How does Dental Handpiece work?

 

How does Dental Handpiece work?

High-speed handpieces have a cutting speed of more than 180,000 rpm. These are known as air turbine and work by increasing speed systems, in dental terms, it is known as the turbine handpiece. The components of the handpiece include a chuck or collet to hold the cutter. While a cutter is known as a burr or bur.

The functionality of the handpiece is based on the turbine and air supply. The compressed air between 35 and 61 passes the center of the equipment and rotates a windmill present on the head of the handpiece, there is present the bearing housing that holds the friction grip burr firmly. There are present small lubricated bearings that allow the burr to rotate. It uses minimal friction along a central axis. The O rings are present through which the O rotor is fixed. It gives the perfect centric during rotation. This allows small movement of the rotor in the head.

Sometimes the burr doesn’t run efficiently. It is because of the following reasons

It may result in eccentric cutting that will result in irregular removal of the surface. It may cause more removal of the tissues.

The burr having judder cause damaging or excessive vibrations. It results in the crazing or cracking of metal bearings. Moreover, it creates an unpleasant experience for patients. It may result in decreased control. Thus, the dentist may not control and may cause inconvenience for patients.

Cooling of Handpiece

The handpieces when work at high speed become hot and create heat in the burr. Therefore, it is important to have a water cooling system. The standard of 50 ml/min is delivered via a spray hole jet to keep the instrument cool during operation.

Illumination System

The modern technology handpieces come with the light feature, the light is directed towards the oral cavity to assist the intraoperative vision. The old instruments had halogen bulbs and fiber optic rods but these were expensive. Moreover, the fiber optic rods were damaged easily. Plus, it deteriorates in the repeated autoclaving cycle. In modern handpieces, there is a present LED. These are long working, need less maintenance, and create intense light as well as minimum heat production. Moreover, these are easy to replace.

How to Maintain the Dental Lab Handpiece?

 

To ensure safe usage with patients, the dentist has to follow the following tips to keep equipment sterilized and safe to use

Cleaning Externally

It is important to thoroughly clean the equipment. For best results use the soft or medium bristle brush. For ease, you can use warm water or alcohol. Apply on a damp cloth and then clean the surface.

Avoid using the chemical that causes damage to the machine or does not dip in the water as it will harm the internal parts of the handpiece. Moreover, avoid placing in ultrasonic cleaner as the circuit of dental electromotor may get damaged.

Use of Washer-Disinfector

A thermal washer-disinfector is the best way to clean the handpieces. The thing you have to focus on is to remove the handpiece after using a washer-disinfector. Moreover, don’t leave the handpiece in the washer overnight.

Clean or Lubricate Deeply

It is important to use good quality service oil and the correct adaptor. Take it and insert it in the handpiece. Moreover, spray for approximately 2 seconds till the oil comes from the head. Do not over oil the handpiece. For better functionality lubricate the spindle or chunk once a day. Use pointed lubricant for this purpose.

Expel Out Excess Lubricant and Debris

To do this step you have to connect the handpiece and insert a bar in the tubing. Now run the handpiece for about 10 to 20 seconds after adding oil. You have to do this step before sterilization. It will help to keep the handpiece clean.

Sterilization

The handpiece is the medicated device. You have to use it in the oral cavity. Therefore, it is important to keep it sterilized. For this purpose keep it in a sterilizer and run the dry cycle. After sterilization removes it from the autoclave. Do not keep it in the autoclave after sterilization is complete.

Keep it Dry

When sterilization is complete, remove it from the autoclave. Now store it in an upright position so it dry internally. Never use it when it is hot or wet. Moreover, never cool it under tap water. Rather place it in a controlled environment and let it cool as well as dry.

Air Supply Checking

To get the efficient working of handpiece always check the air supply in it. Make sure the pressure should not exceed 2.8bar/40psi. if pressure is high it may cause the bearing failure. Therefore, maintain pressure. Furthermore, the air supply must be dry and clean to avoid any unhygienic issues.

These are important tips to follow for handpieces. When you treat a patient, then immediately keep the handpiece in an autoclave and sterilize it. Do not delay as it may be dangerous for the clinic environment and you may suffer from an infection. Therefore it is the responsibility of the technician to sterilize, lubricate, and clean the handpiece to ensure the safety of other staff and patients.
