Can a high speed handpiece be repaired, and how much does it cost to fix one?

 

Turbine Replacement

 

Introduction

 

High-speed handpieces are indispensable tools in modern dentistry, enabling dental professionals to perform precise and efficient procedures. Like any mechanical device, these handpieces are subject to wear and tear over time, necessitating repairs to maintain their functionality. In this article, we will explore the various repair options available for high-speed handpieces and discuss the associated costs for each. 

 

 

Some well-known brands of high-speed dental handpieces include:

1. NSK

2. KaVo

3. Bien-Air

4. W&H (W&H Dentalwerk)

5. Sirona (Dentsply Sirona)

6. Midwest (DENTSPLY Midwest)

 

 

• New Turbine (Manual Style and Auto Chuck)

One of the most common repair options for a malfunctioning high-speed handpiece is replacing the turbine. The turbine is the central component responsible for the handpiece's rotation, and it can wear out over time due to constant use. Depending on the design of the handpiece, it may come with a manual-style turbine or an auto chuck. Replacing a damaged turbine with a new one can range from $100 to $300, depending on the handpiece's make and model.

 

 

• Turbine Overhaul

For some high-speed handpieces, an overhaul of the existing turbine may be possible. This involves disassembling the turbine, replacing worn-out bearings and other damaged components, and reassembling it to restore its functionality. An overhaul can be a cost-effective option, typically ranging from $99 to $250, depending on the extent of the repairs required.

 

• O-Rings

O-Rings play a vital role in preventing water and air leakage in high-speed handpieces. Over time, these rubber seals can deteriorate or become damaged, leading to decreased performance. Replacing O-rings is a relatively simple and inexpensive repair, costing around $10 to $30.

 

• Cleaning of Handpiece Shell and Head

Cleaning the handpiece shell and head is an essential step in any repair process. Removing debris, contaminants, and residual materials not only improves the handpiece's appearance but also ensures smooth operation. Cleaning costs are typically minimal, ranging from $20 to $50.

 

• Lubrication of Bearings

Proper lubrication of the handpiece bearings is crucial to reduce friction and prevent premature wear. Lubrication is often included in regular maintenance services and can cost around $20 to $50.

 

• Chuck Concentricity Test

Checking the chuck's concentricity ensures that it securely holds the bur or tool in the center, preventing vibrations and improving overall performance. The cost for a chuck concentricity test is usually around $30 to $50.

 

• Testing Under Load

Testing the handpiece under load involves examining its performance while operating at full speed. This test ensures that the handpiece functions correctly during actual use. The cost for testing under load is usually around $30 to $50.

 

• Polishing of Shell

Polishing the handpiece shell restores its aesthetic appeal and can be included as part of regular maintenance. The cost for polishing is generally around $20 to $50.

 

• End Gasket Replacement

Replacing the end gasket is necessary if there is air or water leakage in the handpiece. The cost for this repair is usually around $30 to $50.

 

• Cleaning/Flushing of Air-Water Lines

Cleaning or flushing the air-water lines is vital for maintaining proper water spray and air pressure in the handpiece. This step is often included in regular maintenance services and costs around $20 to $50.

 

Conclusion

In conclusion, a high-speed handpiece can be repaired through various methods, depending on the extent of damage and the specific components involved. From replacing the turbine to overhauling the existing one to minor repairs like O-ring replacement, cleaning, and lubrication, each repair option comes with its associated cost. Regular maintenance is key to extending the handpiece's lifespan and minimizing the need for extensive repairs. Dental professionals should weigh the repair costs against the benefits of investing in a new handpiece to make informed decisions for their practice.

 

Turbine Rebuild

 

Introduction

High-speed dental handpieces are essential tools that allow dentists to perform a wide range of procedures with precision and efficiency. Over time, these handpieces can experience wear and tear, leading to reduced performance and potential breakdowns. One common repair option for addressing these issues is a turbine rebuild. This article will also reflect how we will explore the feasibility and cost of fixing high-speed dental handpieces through a turbine rebuild, focusing on various subtopics such as bearing replacement, O-rings, end gasket, cleaning, lubrication, chuck concentricity test, testing under load, and polishing of the shell.

• Bearing Replacement

The turbine in a high-speed dental handpiece contains bearings that facilitate smooth rotation at high speeds. Bearings can wear out over time due to the friction and heat generated during operation. In a turbine rebuild, replacing worn-out bearings is a critical step to restore the handpiece's performance. The cost of bearing replacement typically ranges from $50 to $100, depending on the handpiece model and the type of bearings used.

 

• O-Rings

O-Rings serve as crucial seals within the handpiece, preventing air and water leakage during use. Over time, O-rings can become damaged or worn, leading to compromised functionality. Replacing O-rings is a relatively straightforward and inexpensive repair, costing around $10 to $30.

 

• End Gasket

The end gasket is responsible for sealing the back end of the handpiece, ensuring that air and water remain contained within the appropriate channels. A damaged or worn end gasket can cause air and water leaks, affecting the handpiece's performance. Replacing the end gasket as part of a turbine rebuild typically costs around $30 to $50.

 

• Cleaning of Air-Water Lines

Proper air-water flow is essential for cooling the handpiece during use. Over time, debris and contaminants can accumulate in the air-water lines, leading to reduced water spray and cooling effectiveness. Cleaning or flushing the air-water lines is a routine maintenance step that is often included in a turbine rebuild, and the cost for this service is usually around $20 to $50.

 

• Cleaning of Handpiece Shell and Head

Cleaning the handpiece shell and head is an essential aspect of any repair process. Thoroughly removing debris, contaminants, and residual materials improves the handpiece's appearance and functionality. Cleaning costs are generally minimal, ranging from $20 to $50.

 

• Lubrication of Bearings

To ensure smooth rotation and minimize friction, the handpiece bearings require proper lubrication. Lubrication is a routine maintenance task that is typically included in a turbine rebuild and costs around $20 to $50.

 

• Chuck Concentricity Test

The chuck concentricity test evaluates the chuck's ability to securely hold the bur or tool in the center, preventing vibrations during operation. This test is crucial for the handpiece's overall performance. The cost for a chuck concentricity test typically ranges from $30 to $50.

 

• Testing Under Load

Testing the handpiece under load involves evaluating its performance during operation at full speed. This test ensures that the handpiece functions correctly during actual use. The cost for testing under load is generally around $50 to $100.

 

• Polishing of Shell

Polishing the handpiece shell is a cosmetic step that restores its appearance. While not directly related to the handpiece's functionality, it can be included in a turbine rebuild service, typically costing around $20 to $50.

 

Conclusion

A turbine rebuild offers a viable and cost-effective solution for fixing high-speed dental handpieces that are experiencing wear and performance issues. By addressing various aspects such as bearing replacement, O-rings, end gasket, cleaning, lubrication, chuck concentricity, testing under load, and shell polishing, the handpiece can be restored to its optimal condition. Routine maintenance and timely repairs are crucial to extending the handpiece's lifespan and ensuring consistent performance in dental procedures. Dental professionals should consider the feasibility of a turbine rebuild against the cost of a new handpiece to make informed decisions for their practice.
