Advanced Pre-prosthetic Oral Surgery

Question 1

Does the mand or max resorb more quickly?

Answer 1

Mand 4x quicker

Question 2

Maxilla: most commonly resorb in what area?

Answer 2

near hamular notches

Question 3

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.

Answer 3

Ridge augmentation

Question 4

• 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.

Answer 4

Relative ridge augmentation

Question 5

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.

Answer 5

Relative Ridge Augmentation

Question 6

How much bone must be present for relative ridge augmentation?

Answer 6

2 cm or more

Question 7

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.

Answer 7

Absolute Ridge Augmentation

Question 8

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.

Answer 8

Absolute Ridge Augmentation

Question 9

________ 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

Answer 9

Vestibuloplasty

Question 10

• 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.

Answer 10

Grafting vestibuloplasty

Question 11

What type of disection is needed for grafting vestibuloplasty?

Answer 11

Supraperiosteal

Question 12

How are vestibuloplastys maintained to prevent relapse?

Answer 12

Skin graft, mucosa graft, stents

Question 13

Using alveolar distraction osteogenesis, how much height can be gained per day?

Answer 13

1 mm
