Figure Lengend Snippet: Velopharyngeal extension positioning and attachment for patient-individualized TPP prototypes using Meshmixer. ( A ) Positioning of the extension on the maxillary model, aligning the extension’s design corner with the posterior maxillary gingival landmarks (red) and the middle of the maxilla using the papilla incisive (blue) as a reference, creating a transversal reference by the first (orange) and sagittal by the second (green). ( B ) Horizontal view showing the depth of the extension in the maxillary model. ( C ) Close-up view of the depth and positioning of the extension using a transversal cutting plane through the digital model. ( D ) Close-up view of the depth of the extension position using a sagittal cutting plane through the digital model. ( E ) Addition of the base plate to the digital model and standard extension. ( F ) Alignment of the base plate to the digital model and standard extension setup, ensuring the negative of the palatal base aligns with the model. ( G ) Construction of extensions in 2 mm increments in the sagittal direction: base design (green, no. 2), anterior design (blue, no. 3), and posterior design (purple, no. 1). ( H ) Lateral view of the final base plate and extension setup. ( I ) Top and bottom views of the plate prototype before refining connecting structures. ( J ) Top and bottom view of the plate prototype after refining connecting structures, smoothing, and enlarging areas. ( K ) Finished TPP prototype.
