How to Use a Pindex Dental Unit in a Dental Lab

Precision and efficiency are essential in dental labs, especially when fabricating restorations such as crowns, bridges, and implant-supported prosthetics. The Pindex dental unit is a crucial tool that helps dental technicians create highly accurate sectioned models using laser-guided pin drilling. In this tutorial, we’ll walk through the step-by-step process of using the Pindex dental unit for model fabrication.

Step 1: Model Preparation

Before using the Pindex unit, ensure the dental cast model is properly trimmed and smooth. A clean model ensures accurate pin positioning and prevents unnecessary damage during drilling.

1. Start by trimming the plaster base to create a flat and stable surface.
2. Ensure no excess gypsum or air bubbles are present.
3. Mark key reference points to guide pin placement.

Step 2: Positioning & Laser-Guided Drilling

The Pindex dental unit features laser positioning technology, allowing precise hole placement for dowel pins.

1. Place the model on the Pindex unit’s drilling platform. Ensure it is secure.
2. Activate the laser guide, which projects a precise drilling point onto the model.
3. Using the one-touch automatic drill, create clean, perpendicular holes where dowel pins will be inserted.
4. Repeat this process for each section of the model.

Step 3: Inserting Dowel Pins

Dowel pins help align and secure individual model sections, allowing technicians to work on specific areas without misalignment.

1. Apply a small amount of adhesive to each pin base for better fixation.
2. Insert each pin into the drilled holes, ensuring a snug fit.
3. Double-check pin alignment to avoid errors when repositioning model sections.

Step 4: Model Sectioning & Base Mounting

Once the dowel pins are secured, the model must be carefully sectioned and mounted.

1. Use a diamond saw or scalpel to separate the model into individual sections.
2. Ensure each section aligns perfectly with the base for a seamless fit.
3. Attach the sections onto a mounting base, allowing easy access for dental restoration work.

Step 5: Final Adjustments & Verification

Before proceeding with restorations, verify the accuracy of the sectioned model.

1. Check for proper fit and stability of each section.
2. Ensure pins allow smooth repositioning without misalignment.
3. Once confirmed, the model is ready for wax-ups, framework design, and prosthetic fabrication.

Conclusion

Using a Pindex dental unit helps technicians achieve high-precision dental models, improving fabrication accuracy while saving time. With laser positioning and one-touch drilling, the Pindex system streamlines the workflow in any dental lab.
