Study Notes
Palatine Rugae
- Anatomical folds/wrinkles on the anterior third of the hard palate, behind the incisive papilla.
- Number varies between 3 and 5 on each side.
- Doesn't extend beyond the anterior half of the hard palate.
- Never crosses the midline.
- Anterior rugae are typically more prominent than posterior rugae.
Palatine Rugae Shape
- Can be described as circular, straight, curved, diverging, wavy, or converging.
Palatine Rugae Characteristics
- Stable during growth.
- Unique to each patient.
- Maximum mean change in distance between rugae in the anteroposterior plane is 0.41 mm.
- Show stability following orthodontic treatment.
Palatine Rugae Significance
- Reference points: Useful in cast analysis.
- Forensic identification: Unique patterns aid in identifying individuals.
- Protection: Anatomical position (surrounded by soft tissues and bone) protects from trauma and high temperatures.
- Speech and palatal prostheses: Crucial for palatography (determining tongue's contact position for speech sounds) and denture fabrication. Lack of rugae texture on dentures can alter proper tongue-palate articulation.
