Every dental student remembers the first time they pick up a high speed handpiece. It is loud, fast, and powerful. Standing in front of a typodont with 28 plastic teeth can feel intimidating. However, this training is the most important step in becoming a skilled dentist.
Here is a simple guide to mastering your skills on the model.
1. The Basics: How to Hold and Control
Before you start drilling, you need the right foundation. Precision is more important than speed.
- The Pen Grasp: Hold the handpiece like you hold a pen. This gives you the best control.
- The Finger Rest: Never float in mid-air. Always rest a finger on a stable tooth nearby. This prevents slips and protects soft tissue.
- Keep it Light: Do not squeeze the handpiece too hard. A loose grip helps you feel the vibrations of the tooth better.
2. Know Your Tools: Air vs. Electric
In the clinic, you will mainly use two types of handpieces. Both are high speed, but they feel very different.
- Air Turbine: This is the classic “whistling” drill. It is powered by compressed air. It is very fast but has less cutting power when you press down.
- Electric Handpiece: This is powered by a motor. It is heavier and cuts smoother. It maintains speed even under pressure.
3. Comparison and Usage Suggestions
Choosing the right tool for the job makes your preparation easier. Here is a simple comparison table to help you decide.
| Feature | Air Turbine Handpiece | Electric Handpiece |
|---|---|---|
| Power Source | Compressed Air | Electric Motor |
| Sound | High-pitched whine | Lower, steady hum |
| Torque (Power) | Low; stops if you press too hard | High; constant speed & power |
| Lighting | Often external or basic LED | Usually bright, integrated LED |
| Best For | Rapid enamel removal, cavities | Crown preps, fine margins, smoothing |
| Cost | Generally cheaper | Generally more expensive |
| Usage Suggestion | Use for the “rough work” or opening cavities. | Use for defining final shapes and heavy cutting. |
4. Practical Tips for the 28-Tooth Model
Now, let’s apply this to your training model.
Using the Air Turbine:
- Pecking Motion: Do not drag the bur across the tooth. Use a light, up-and-down pecking motion. This prevents the bur from getting too hot and clogging with plastic.
- Let the Bur Cut: The air turbine spins fast, but it is weak. Do not force it. Let the speed do the work.
Using the Electric Handpiece:
- Watch Your Depth: The electric handpiece is powerful. It cuts through plastic very quickly. Be careful not to go too deep.
- Smooth Moves: Use long, sweeping strokes. It is perfect for creating smooth shoulder margins on your crown preps.

Conclusion
Training on a model is the safe place to make mistakes. Whether you are using an air turbine or an electric handpiece, the goal is control. Start slow, find your finger rest, and listen to the sound of the bur.
With enough practice on those 28 teeth, you will be ready for the real patient in no time. Pick up your high speed handpiece and start drilling
