In completely edentulous patients rehabilitated with 3D-printed maxillary dentures bases, does the printing layer thickness affect candidal adherence and growth on the fitting surface of dentures.

The trial will follow a cross-over design, where each participant will wear denture bases printed with three different layer thicknesses (25 µm, 50 µm, and 100 µm) at a random order. Each participant will wear each of the three dentures for an 8-week period, with a washout period of two weeks between each thickness.

Inclusion Criteria:

• Completely edentulous patients aged 30-80 years
• Oral cavity is free from any mucosal lesions.
• No systemic conditions that would contraindicate participation in the study.

Exclusion Criteria:

• History of allergic reactions to denture materials.
• Active mucosal lesions related to denture use.
• Pregnancy or lactation.
