A new method for denture identification

Area of Science:

• Materials Science
• Biomaterials Engineering
• Prosthodontics

Background:

• Effective denture marking is crucial for patient identification and preventing mix-ups.
• Current methods like labeling (LA) may lack long-term durability under oral conditions.

Purpose of the Study:

• To compare the durability of three denture marking methods.
• To evaluate the impact of common denture cleansers and beverages on marking integrity.

Main Methods:

• Three marking techniques were applied to heat-cured acrylic resin specimens: Labeling (LA), Direct printing with autopolymerizing resin (DA), and Direct printing with bonding resin (DB).
• Specimens were immersed in sodium hypochlorite (NaOCl), denture cleanser, and coffee.
• RGB values were measured from photographs to assess color changes and durability.

Main Results:

• The Direct printing with autopolymerizing resin (DA) method showed minimal changes in RGB values after immersion.
• Significant differences in durability were observed between the Labeling (LA) and Direct printing with bonding resin (DB) methods.
• The DA method demonstrated superior durability compared to the commonly used LA method.

Conclusions:

• Directly printing marks onto dentures and covering with autopolymerizing acrylic resin (DA) is a more durable denture marking technique.
• This method offers improved longevity and reliability for denture identification compared to traditional labeling approaches.
