Lec 8: Preparation of the Mouth for RPD

Question 1

Conditions that address that puts the prosthesis into comfort.

Answer 1

Mouth preparation

Question 2

Done for proper tooth stabilization and support.

Answer 2

Tooth alteration

Question 3

Objective of this procedure is to create an optimum health and eliminate or alter any condition that would be detrimental to the functional success of the RPD.

Answer 3

Mouth preparation

Question 4

Recommended to survey the jaws for unsuspected pathologic conditions.

Answer 4

Panoramic radiographs of the jaws

Question 5

The patient should be informed of the diagnosis of this conditions and provided with various options for resolution of the abnormality, as confirmed by pathologist’s report.

Answer 5

Cysts and Odontogenic tumors

Question 6

RPD components in proximity to this type of tissue may cause irritation and chronic ulceration.

May also complicate maintenance of periodontal health and lead to eventual loss of strategic abutment teeth.

Answer 6

Bony exostoses and Tori

Question 7

Excess tissues removed to provide a firm base for the denture. Removal will produce a more stable denture, reduce stress and strain, and provide a more favorable orientation of occlusal plane and arch form.

Answer 7

Hyperplastic tissue

Question 8

4 Muscles that are most likely to cause problems on attachments.

Answer 8

1. Mylohyoid
2. Buccinator
3. Mentalis
4. Genioglossus

Question 9

Excised and submitted for pathologic examination before fabrication of RPD. Stimulation to the area by prosthesis may produce discomfort or undesirable changes.

Answer 9

Polyps, papillomas, and traumatic hemangiomas

Question 10

Should be investigated; lesions should be removed and healing accomplished before RPD is fabricated.

Answer 10

Hyperkeratosis, Erythroplasia, and Ulcerations

Question 11

An imbalance of the position, size, shape, or orientation of the bones that comprise upper and lower jaws due to skeletal growth disturbances.

Answer 11

Dentofacial deformity

Question 12

Causes of dentofacial deformity? (4)

Answer 12

• Childhood fractures of the jaw
• Muscle dysfunction
• Genetic influences
• Other diseases

Question 13

• Enhance functional comfort
• Support the replacement of teeth
• Has significant stabilizing effect on dental prosthesis through a rigid connection on living bone.

Answer 13

Dental implants

Question 14

• Usually follows any surgical procedure.
• Performed simultaneously with tissue conditioning procedures.
• Should be completed before any restorative dentistry procedures are begun.

Answer 14

Periodontal preparations

Question 15

Objective of this procedure is to return to health the supporting structures of the teeth, creating an environment in which periodontium may be maintained.

Answer 15

Periodontal preparations

Question 16

First phase of periodontal treatment

Answer 16

Disease control (initial therapy)

Question 17

Patients who require conditioning treatment often demonstrate which symptoms? (3)

Answer 17

1. Inflammation & irritation of mucosa
2. Distortion of anatomic structures
3. Burning sensation in ridge

Question 18

These conditions are usually associated with ill-fitting or poorly occluding RPDs.

Answer 18

Abused & Irritated Tissues

Question 19

Abutment restorations used on canines and premolars for abutment restorations.

Answer 19

Answer 21

Proximal gingival area

Question 22
