OS- pre prosthetic surgeries Flashcards
Why do we have surgery pre-prosthetics?
Hard or soft tissues in the mouth can affect the fit of a denture so we surgically remove them.
What is a frenectomy ?
Removal of the frenum
What is a frenoplasty?
Modification of the frenum
What is papillary hyperplasia?
Overgrown soft tissue on the palate which is commonly related to candida infections or a poorly fitted denture.
Descibe the clinical presentation in this picture
Flabby ridges- the soft tissue on the ridge interferes with denture retention.
Can happen with combination syndrome.
Describe the clinical presentation in this picture
Denture induced hyperplasia-
Check if the ulcer goes away if denture is removed.
Commonly happens if patient wears a temporary denture long term.
What is a vestibuloplasty?
Deeping of the sulcus by exposing the periosteum to achieve ridge extension
What is an alveoplasty?
Modification of the alveolar process.
What is the problem with a knife edge alveolar process and how do we treat it?
Denture will push soft tissues onto it causing pain.
We expose the bone and smooth ridge with a bone file.
what is this?
Torus (a bony promienence)
Compare tori and exostoses?
Tori are found where there is already bone,
Exostoses are found somewhere that there is not normally a bony promience.
When would we need to reduce the genial tubercule or mylohyoid ridge?
If there is severe bone resorption causing the promiences to come to the surface and rub with the denture causing pain.
Why would we alter the frenum labially?
It can affect oral hygeine
Why would we avoid altering the frenum buccally
Risk of damage to the nearby mental nerve.
