Restorative options for root filled teeth Flashcards
what is the root filled tooth at risk of
what other 2 things is the root filled tooth risk of
what is the risk of patient not having pulp
Without pulp, patients don’t know what they’re doing so much- overload, biting
How do we preserve dentin,enamel yet still achieve root canal
what are the 4 principles of restoring root filled teeth
what is restoration
describe the coronal tissue assessment before RCT
what other factors would you consider in coronal tissue assessment
what is the ferrule effect
Post is going to fill the canal
Crown isn’t going to overload
Needs to be the right occlsuions
Prepare post
Instead of using tooth tissue, the crown is overlapped
Occlusal forces supported by crown are transferred around the root
Encircling of natural tooth is achieving the ferrule effect
1.5-2 mm of overlap of crown beyond that natural tooth tissue
what is the Nayyar type core
Molar
Place composite in
And place large composite into coronal aspect of root canal
Crown on the top achieving ferrule
Core - enough tooth tissue to bond too
Why do we use posts
Describe different types of post
what are the lab stages involved in cast post and core
Rarely done due to better alternatives
- a post is cast along with the core in the lab and this single unit is then cemented into the tooth at a further visit
- a temporary post and core is needed between appointments
the first stage of post involves
Lab casts up the dental impression
Pour it , they have a model
sLab can construct a post
what is an endo crown
what is failure of restored root filled teeth
Drill into root canal
Angulations wrong
Rubber dam
- root fracture
- fractured post
- poor coronal seal
When should we restore a root filled tooth with a cusp coverage restoration
