Par 2 - Occlusion & Wax Trial RPD Flashcards
What is key to a successful wax trial RPD?
interocclusal record
What material is used specifically for bite registration?
VPS
Which cast do you use the facebow to help mount?
maxillary
What do you use the interocclusal record for?
to mount the mandibular cast to the maxillary cast
***When you have occlusal wear without loss in vertical dimension, what is the cause?
Passive Eruption
How can you increase VDO?
With fixed restorations or implants (NEVER w/ only an RPD)
- remember: Must ALWAYS maintain “natural tooth contact”
T/F? You can increase VDO with just an RPD.
FALSE. You will need to also use fixed restorations or natural tooth contact — otherwise the pt will have symptomatic joint issues.
What are the determinants of occlusion?
- number & distribution of remaining teeth
- existing periodontal conditions
- opposing occlusion
What is enameloplasty?
a cosmetic dentistry treatment option where the size and shape of an existing tooth’s enamel surface is removed or “shaved” permanently to reshape the contours of the tooth for improved appearance or as a preparation for further treatment, such as veneers or Lumineers.
At what stage do you do enameloplasty?
Prep stage (before you make the framework typically)
T/F? Monoplane is typically indicated in opposing natural teeth.
FALSE. It is typically NOT indicated.
T/F? Monoplane is indicated in prosthetic occlusal schemes.
TRUE.
- Balanced articulation is best.
What is the most common reason that the record is wrong?
Record base was not supportive.
others:
- framework interferes w/ occlusion
- natural tooth movt
- pt changes MIP to accomodate
- error in mounting
When processing, you need to confirm at least ___ mm of thickness in wax.
3 mm
