Toothwear L1 Part 2 - Dentures, Overdentures, & Rehabilitation Flashcards
what are the consequences of lack of posterior support?
- increases severity of wear
- increases rate of progression of wear
- lead to occlusal collapse
- functional & aesthetic problems
why may a pt have lack of posterior support?
- denture intolerance
- denture refusal
- supervised neglect
what is an overdenture?
removable prosthesis that rests on 1 or MORE natural tooth or root of natural tooth
what are advantages of overdentures?
- correction of occlusion and aesthetics
- support
- tooth wear management
- preservation of ridge form
- proprioception
- denture retention
- can be used with precision attachments
- MRONJ & radiotherapy pts - avoids XLA
what are the disadvantages of overdentures?
- need for good OH
- increased caries/perio problems
- denture fracture
- discomfort/infection
what aftercare is needed by the pt for overdentures?
- good OH
- fluoride toothpaste to roots (if present)
- regular examination & radiographs
- denture hygiene
what are transitional dentures used for?
[aka immediate/temporary denture]
- allows the GDP to see if patient can tolerate increased OVD,
- also creates space (increase OVD) for restorations
What type of patient would most likely receive a metal based denture, and why?
Bruxist
this allows denture to still remain retentive whilst also providing stronger resistance to occlusal loads
why do we try to conform to existing occlusion in dentistry?
If patient has sufficient teeth, they are most likely to be the most functional and stable in that occlusion.
You dont want to change their OVD resulting in rehabilitation UNLESS NEEDED.
What happens to the OVD when the occlusion is conformed vs rehabillisation?
Confirming - OVD = remains same
Rehabilitation - OVD = changed
