Pre-Prosthetic Surgery

Question 1

What soft tissue excisional procedures might be indicated?

Answer 1

Frenectomy/frenoplasty

Papillary hyperplasia

Flabby ridges

Denture induced hyperplasia

Maxillary tuberosity reduction

Retromolar pad reduction

Question 2

What hard tissue excisional procedures might be indicated?

Answer 2

Removal of retained teeth/roots/pathology
- retained roots are commonly extracted if the bone is resorbed and the root has come to the surface, causing the patient discomfort.

Ridge defect correction

Mandibular tori

Maxillary tori

Maxillar tuberosity

Exostoses

Undercuts

Genial tubercle reduction

Mylohyoid ridge reduction

Question 3

Why might retained roots require removal later down the line?

Answer 3

Become mobilised

Infection/pathology

Bone resorption has caused them to come to the surface of the bone and causing pain

Question 4

Why might ridge defects have arose?

Answer 4

Anterior teeth lost a long time after the posterior teeth were lost
- posterior ridge resorbed a lot more than anterior.

Knife-edged ridge- sharp bone not removed during extraction.
- Can smooth this area off.

Question 5

What is a Mandiubular Torus?

Answer 5

Bony growth, non-cancerous and nothing to worry about.

Usually bilateral but can be unilateral.
Usually in the premolar region on the lingual side.

Question 6

Do mandibular tori need to be removed?

Answer 6

Wouldn’t remove them unless it is causing a problem with denture retention.

In a dentate person, you would leave them alone.

Question 7

What is a palatal torus/palatal tori?

Answer 7

Bony growth in the palate.

Question 8

Do palatal Tori need to be removed?

Answer 8

Will restrict dengue design- could still do a. horseshoe shaped denture.

But if you need to cover the palate, then it is better to remove.

Question 9

What other factors might need to be removed to aid denture retention?

Answer 9

Prominent maxillary tori
Mandibular tori
Prominent maxillary tuberosity
Prominent buccal frenum
Flabby ridge
Denture induced hyperplasia

Question 10

For a flabby ridge, what could you do?

Answer 10

Tell the patient to not wear their denture until it goes away

Remake a new denture once the hyperplasia has gone.

Surgical removal of flabby ridge and fabrication of new denture.
