One of the most frustrating parts of making your own dentures is when the plaster model breaks after you’ve finished it, rendering all your previous work useless.
In fact, based on our experience, creating a “sturdy and durable” plaster model depends on three factors: materials, technique, and structure.
Dentureway uses high-quality dental stone powder, so the material itself is reliable. What truly makes the difference is how you execute each step and how you ensure proper thickness.
I. Precision in Execution: Get Each Step Right
Step 1: Mixing the Plaster Powder
After combining plaster powder and water:
- Stir for 25–30 seconds
- Press down while stirring
- Smooth the mixture against the bowl’s sides
This removes trapped air bubbles and creates a uniform texture. The final mixture should be smooth and lump-free.
* Dentureway currently offers plaster powder in 70g bags. Only half a bag (35g) is needed to create one upper or lower model, mixed with 15-16ml of water. If you are using other sellers of plaster powder, please calculate the dosage accordingly.
Step 2: Pouring the Mold
Pour slowly in small batches — never all at once.
Use a spatula to press plaster into the tooth socket grooves first. Fill the fine details before gradually filling the entire mold. Make sure no areas are missed.
Step 3: Eliminate Air Bubbles
While pouring, gently tap the tray on the table several times.
The vibration releases trapped air bubbles and significantly improves model strength. Continue tapping until the impression is fully filled.
II. Practical Tips for Stronger Results
- If the mixture thickens, stir it thoroughly again.
- If water must be added, use only 3–5 ml. Never more.
- After pouring, let the model rest undisturbed for at least 45 minutes. Do not move it too soon.
III. Ensure a Solid Impression: Thickness Equals Strength
Thickness determines strength. A model that is too thin will easily break.
If the impression is shallow due to gum recession, apply tape along the outer edge of the blue tray to create a temporary barrier. This increases the base thickness and makes the model more durable.
Following these methods will minimize plaster model fractures and damage, making your DIY denture journey smoother!
