Questions and Answers

What is the purpose of applying Vaseline in the process of making triads or composite base plates?

To enhance the strength of the base plate material
To provide a glossy finish on the base plate material
To prevent adhesion of triad to stone after curing (correct)
To accelerate the curing process of the triad material

Why is it important to adapt the triad-like material carefully to engage soft tissue surfaces, hamular notches, and post dam area?

To ensure maximum strength of the material
To improve patient comfort and fit of the base plate (correct)
To increase the flexibility of the base plate material
To prevent the formation of air bubbles in the material

Study Notes

Process for making triads or composite base plates for setups or bike rooms involves blocking out undercuts with red clay to prevent model damage
Vaseline is applied to prevent adhesion of triad to stone after curing
Triad-like material is adapted carefully to engage soft tissue surfaces, hamular notches, and post dam area
Material is cut and pressed into place, then cured in a light box for five minutes
Similar process is followed for lower base plate after applying vaseline
Base plate material is adapted to lingual areas first before the facial side to avoid thinning out
Excess material is trimmed to form borders between 3-4mm thickness, with a rounded edge for patient comfort
Frenum areas are opened up to accommodate tissue movement and prevent base plate dislodging
Land areas are defined to separate tissue bearing surface from the model edge, ensuring accurate flasking during processing
Final step involves making bite rims using the prepared base plates
