What is the digital workflow for complete dentures?
Data acquisition -> designing -> manufacturing
What is data acquisition?
What is designing?
What is manufacturing?
What are advantages of the digital workflow for complete dentures?
- the elimination of cumbersome denture tooth arrangement
- subsequent resin injection or packing
- reproducibility of the dentures
Why digital dentures? (what are the benefits)
- faster completion time
- less appointments
- lower cost
- digital record, easy duplication
- almost any fully edentulous case
- attractive
- strong
What are the steps of creating a digital complete denture?
- Preliminary impression and fabrication of custom tray: visit 1
- Final impression, fabrication of master cast and recording base and wax rim: visit 2
- occlusal registration (wax or ITD): visit 3
- Scan models and occlusal registration: design denture base and digital mounting
- Digital set up teeth and waxup
- optional denture try in: visit 4
- Delivery: visit 4 or 5
What do you do during the first visit?
Preliminary impression/diagnostic model
- custom trays are then made
What do you do during the second visit?
Final impression and occlusal registration
What is the papillameter measurement?
What is the program called?
AVADENT
What do you do during the 3rd visit?
Trial denture try-in (optional)
What do you do during the 4th visit?
Denture insertion
What are adv/disadvantages of 3D printed resins?
Lower flexural strength and hardness values and higher water sorption and solubility
What is the difference between milled and 3D printed dentures?
No sig. difference in accuracy between milled and 3D printed
