Pros complete dentures tutorial Flashcards
What are the advantage of replica dentures over conventional dentures?
- One less clinical stage
- Jaw registration stage usually simpler
- Easier to adapt as similar to previous denture
- Less change in aesthetics
- Minor changes to design is possible
- Better neuromuscular control of the denture
What are the limitations of replica dentures?
- No major changes can be done
- Acceptance some flaws in the design
- Exact copy not possible
Briefly describe the steps in making a replica denture
- Take moulds of the current denture using stock trays and lab putty out the patient mouth and request replica blocks
- Take Master impression using replica block and jaw registeration
Which base is ideal for a replica denture block construction?
Shellac base
Describe the three steps in the first stage of replica dentures in the laboratory after sending primary impressions?
- Lay shellac base onto fitting surface of moulds
- Pour molten wax into moulds
- Once wax is set, remove completed wax replica blocks on shellac bases
What 3 information would you to the technician to register the occlusion ?
- Shade
- Setting
- Mould
A case where would you choose cuspless teeth?
Very resorbed ridges or if the patient struggles to get into a retruded position
What is the order of setting up the teeth?
- Upper anterior then upper posteriors then upper to lowers ensuring the lowers are over the ridge
What are two curves that are important when setting up posterior teeth?
- Bi lateral curve of Monsen
- Curve of Spee
- This is to achieve balanced articulation
What are 6 try in checks?
- Vertical dimension of occlusion
- Even contact in retruded contact position
- Occlusal planes - anterior and posterior
- Lower teeth over ridge
- Speech
- Retention and stability
- Base extensions
- Appearance
What is the laboratory steps for finishing the dentures?
- Wax up
- Flask
- Deflask
- Trim and polish
When would you review a patient after insertion of denture?
- 1-2 weeks
7 insertion checks?
- Vertical dimension
- Even contact in retruded position
- Speech
- Retention and stability
- Base extension
- Appearance
- Comfort
What would you check when reviewing a denture after insertion checks?
- Aesthetics
- Function
- Pain,redness and ulceration
- Speech
- Occlusion and vertical dimension
A patient come at review and you notice some ulceration, what would be your management?
- Take out denture
- Apply pressure indicating paste
- Insert the denture and let patient bite then remove and adjust using straight handpiece any high areas
