4 - Pre-prosthetic surgery Flashcards
What are the different types of soft tissue surgery?
- excisional
- ridge extension
- augmentation
What are the different types of hard tissue surgery?
- excisional
- augmentation
- other (implants, IAN relocation)
What are the different types of excisional soft tissue surgeries?
- frenectomy
- frenoplasty
- papillary hyperplasia
- flabby ridges
- denture induced hyperplasia
- maxillary tuberosity reduction
- retromolar pad reduction
Define frenectomy.
Complete removal of a frenum
less common, usually modify
Define frenoplasty.
Change the shape of a frenum
Why do frenums require surgery?
- interfere with OH
- denture retention
Define vestibuloplasty.
- ridge extension procedure (deepening sulcus)
- maxilla or mandible
- very uncommon
What soft tissue augmentation procedures are undertaken?
Soft tissue graft
What are the different types of excisional hard tissue surgeries?
- removal of retained teeth/roots/pathology
- alveoplasty
- mandibular and maxillary tori
- maxillary tuberosity
- exostoses -bony lump
- undercuts
- genial tubercle reduction
- mylohyoid ridge reduction
Define alveoplasty.
Ridge defect correction
Define exostoses.
Bony lumps found elsewhere in the mouth (other than tori)
Why are genial tubercle or mylohyoid ridge reduction surgery required?
- if teeth are lost/extracted the ridge resorbs
- in extreme cases, the ridge resorbs far down, denture flange rubbing against them
What hard tissue augmentation procedures are undertaken?
- autografts
- allografts
- xenografts
- synthetic grafts
Define autograft.
Graft from the patient
iliac crest/ rib
Define allograft.
- graft from another human
- often caderveric bone
- cells are removed, calcified matrix remains
