Advanced Pre-prosthetic Oral Surgery Flashcards
Does the mand or max resorb more quickly?
Mand 4x quicker
Maxilla: most commonly resorb in what area?
near hamular notches
It is a surgical procedure that aims at increasing the quantity and/or quality of bone or soft
tissues in edentulous area of the oral cavity.
Ridge augmentation
• Indicated for a flat ridge with moderate resorption of the alveolar bone.
• Procedures that involve sulcus lengthening(Vestibuloplasty). In this procedure, the
alveolar mucosa and muscle insertions can be repositioned apically.
Relative ridge augmentation
Indication for _______ in the Mandible
- If there is 2 cm or more bone present at the mid-body of the mandible.
Height will be increased in the symphysis and the mid- body regions.
Relative Ridge Augmentation
How much bone must be present for relative ridge augmentation?
2 cm or more
Indicated for a flat ridge with extreme resorption of the alveolar bone.
Osteotomy and bone grafting are indicated to augment the height of the ridge, actually increasing
the bone height.
Subsequent muscle repositioning may be necessary to achieve desired results.
Absolute Ridge Augmentation
Indication for __________ in the Mandible:
• Indicated when there is extreme resorption of the body of the mandible.
• There is less than 2cm bone at the mid-bodyof the mandible.
Absolute Ridge Augmentation
________ is a soft tissue surgical procedure designed to increase:
- Surface area of fixed tissue for denture support
- Depth of vestibules for denture flange extension
- Used to prepare for either complete or partial dentures
Vestibuloplasty
• Following vestibuloplasty, the periosteum is
uncovered.
• If this vestibuloplasty wound is allowed to
granulate it usually results in relapse, especially
on the labial surface. Therefore, to prevent this, a
skin or palatal mucosal graft is usually placed
over the periosteum.
• The skin is removed from the outer surface of
the thigh, while the palatal mucosa is usually
taken from the palate.
Grafting vestibuloplasty
What type of disection is needed for grafting vestibuloplasty?
Supraperiosteal
How are vestibuloplastys maintained to prevent relapse?
Skin graft, mucosa graft, stents
Using alveolar distraction osteogenesis, how much height can be gained per day?
1 mm
