What is Post retained crown?
A post and core crown is a type of dental restoration required where there is an inadequate amount of sound tooth tissue remaining to retain a conventional crown. A post is cemented into a prepared root canal, which retains a core restoration, which retains the final crown.
When dowel post is to be made how long of the gutta percha is left in the canal?
A minimum 3-5 mm of gutta percha should remain at apical end to preserve the apical seal. Apical seal should be confirmed radiographically.
Which tool is used in the canal for a post preparation for retention after root canal treatment?
Files and Reamers: These are long drill bits, consisting of various sizes used to open and expand the canal before inserting the other tool to finish the work. Dentists use different sizes of files and reamers.
Why is my post crown loose?
Bad habits like teeth grinding, chewing on hard things or eating lots of sticky foods can weaken the grip of the dental cement and lead to the crown becoming loose.
