Resistance of Photopolymer Resin-Based Dental Prosthetics Against Harmful Substances

Nowadays, dental prosthetics produced using 3D printing and milling methods have become highly popular for both temporary and permanent use. However, smoking and other harmful substances can shorten the lifespan of these prosthetics, cause discoloration, and damage their surface structure. In this article, we will discuss substances that can harm dental prosthetics and precautions that can be taken against them.

Effects of Smoking and Tobacco Products

Cigarette smoke, due to its tar, nicotine, and other chemicals, can cause significant discoloration and surface degradation in dental prosthetics. Prolonged use, in particular, can damage the aesthetic appearance of prosthetics, leading to yellowing and staining. Additionally, cigarette residue adhering to the prosthetic surface can create hygiene issues.

Hookah and electronic cigarettes are also harmful, just like traditional cigarettes. Hookah, in particular, contains a high amount of tar, causing prosthetics to discolor more rapidly. Electronic cigarettes contain various chemicals that may negatively affect the surface structure of prosthetics.

Other Substances That Can Damage Dental Prosthetics

Aside from smoking, certain foods and beverages can also negatively impact the color and durability of dental prosthetics:

1. Pigmented and Acidic Beverages

• Coffee and Tea: Due to their tannin content, they can cause yellowing and staining on prosthetics.
• Red Wine: With its high pigment content and acidic nature, it can lead to discoloration.
• Carbonated Beverages (Cola, Energy Drinks): Their combination of acids and sugars can deteriorate the prosthetic surface, leading to stains and erosion.

2. Alcohol and Chemically-Based Substances

• Alcohol-Based Mouthwashes: Can cause prosthetic materials to dry out and crack.
• Vinegar and Citrus Fruits: Their high acidity can erode the surface of the prosthetic, reducing its durability.

3. Abrasive Substances

• Harsh Toothpastes: Contain large particles that can wear down the prosthetic surface, making it more prone to staining.
• Abrasive Cleaners: Can weaken the material of the prosthetic, causing it to become dull and rough.

Precautions to Increase the Durability of Dental Prosthetics

To make dental prosthetics more resistant to smoking and other harmful substances, the following precautions can be taken:

• Regular Cleaning: Clean your prosthetics daily with a soft brush and appropriate cleaning agents.
• Use of Alcohol-Free Mouthwashes: Avoid alcohol-based products to prevent the prosthetic from drying out.
• Professional Maintenance and Polishing: Periodic treatments by a dentist can keep the surface smooth and reduce discoloration.
• Choosing Low-Acidity and Non-Pigmented Foods: Limiting acidic and pigment-rich beverages can extend the lifespan of prosthetics.

3D-printed dental prosthetics, thanks to advanced materials, can be long-lasting and aesthetically satisfying. However, substances such as cigarettes, coffee, tea, alcohol, and abrasive chemicals can damage their surface structure, cause discoloration, and reduce their durability. Therefore, by adopting proper care and cleaning habits, you can maintain your prosthetics in a healthy and aesthetically pleasing condition for many years.
