2. Tx Planning I

Question 1

Describe the sequence of flow for treating a patient

Answer 1

urgent need –> disease control –> rehabilitation –> maintenance

Question 2

What should you do before referring someone to endo for RCT after making a dx?

Answer 2

determine if the tooth is restorable

Question 3

If a patient is in pain and it is unclear as to whether or not the tooth is restorable and the patient wants to save the tooth what should happen

Answer 3

emergency endo to alleviate pain

Question 4

What is the emergency endo treatment for a tooth with symptomatic irreversible pulpitis and no percussion sensitivity that is single/two rooted

Answer 4

clean and shape

Question 5

What is the emergency treatment for a multi-rooted tooth with symptomatic irreversible pulpitis that is not percussion sensitive

Answer 5

pulpotomy

Question 6

What is the emergency treatment for a tooth with symptomatic irreverxible pulpitis that is sensitive to percussion

Answer 6

Clean and shape

Question 7

What is the emergency treatment for a necrotic tooth

Answer 7

Clean and shape

Question 8

Identify the principles of treatment planning (in the correct sequence)

Answer 8

• ID all problems
• Establish treatment goals
• ID patient specific modifiers/risk factors
• Determine appropriate treatment procedures
• Organize all procedures into sequence

Question 9

What are the Fixed prosthodontitis goals of treatment

Answer 9

• Prevention of future disease
• Correction of existing disease
• Restoration of function
• Improved esthetics

Question 10

T/F People who brush 3x/day have significant’y less risk for caries than those who brush 2x/day

Answer 10

F but there is a significant difference in caries risk between those who brush 1x/day and 2x/day

Question 11

Reading mentioned on slide 19- be sure to read

Answer 11

ok

Question 12

What components make up prevention of future disease

Answer 12

• OHI

- Caries risk assessment

Question 13

What components make up correction of existing disease

Answer 13

• Scaling and root planing
• Extraction of hopeless teeth
• Replacement of defective restorations
• Removal of carious lesion
• Recontour overcontoured restorations (esp near furcations)
• Therapeutic and/or surgical perio therapy

Question 14

Considerations for foundations for fixed restoratiosn

Answer 14

• Retention of the foundation to the remaining tooth structure (need a post??)
• Strength of foundation
• Color of foundation (esthetic)
• Parafunctional habits (loss of VDO)
• Behavioral problems (bulemia/anorexia)

Question 15

Fixed restorations on individual teeth are indicated when

Answer 15

• Extensive caries
• Heavily restored (> or equal to 50%)
• Following RCT (posterior teeth)
• Fractures
• Replace inadequate restorations (esthetic issue with previous crown- ie wrong shade match)
• RPD abutment (survey crown)
• Developmental problems (amelogenesis imperfecta)

Question 16

What is the purpose of survey crowns

Answer 16

remaining teeth for a partial denture often lack optimal contours to retain an RPD- survey crowns give optimal contours

Question 17

What are the indications for replacing missing teeth

Answer 17

• Functional deficit (chewing and speech)
• Esthetic issue
• Potential for problematic tooth movement (not an absolute indication)

Question 18

Chewing ability is superior for an (RPD/FDP)

Answer 18

FDP

Question 19

Chewing performance is proportional to

Answer 19

number of occluding units

Question 20

Article on the shortened dental arch slide 43 read

Answer 20

ok

Question 21

What is the shortened dental arch (SDA)

Answer 21

• Continuous (2nd PM to 2nd PM) with no intermediary missing teeth
• Functionally acceptable for most patients
• No significant predisposition to tooth wear or migration
• No significant alteration in diet
• Acceptability (psychologically and esthetically) acceptibility must be ascertained on an individual basis

Question 22

What are the treatment options for replacing missing teeth

Answer 22

• Implant
• FDP
• RPD
• Nothing

Question 23

What are the factors that influence the choice of treatment for the replacement of missing teeth

Answer 23

• Length of edentulous span
• Soft tissue defects
• Condition of abutment teeth
• Practical issues (medical health, money and time)

Question 24

What is ante’s law

Answer 24

Says that the surface area of the abutment teeth should be greater than or equal to the root surface area of the teeth being replaced

Question 25

What are the indications for an RDP

Answer 25

-Long edentulous span, absence of distal abutment tooth
(vertical support needed from the ridge)
-Where resistance to lateral movement is needed from the contralateral teeth and soft tissues
-Hard/soft tissue deficiency
-Money
-Need to replace a soft tissue/bony space with flange

Question 26

Options for replacing teeth in a short edentulous span

Answer 26

• FDP
• Implant
• Adhesive (maryland) bridge

Question 27

What are the indications of an adhesive bridge

Answer 27

Indications

• 1-2 missing teeth
• Abutment teeth present on either end
• Abutments have favorable alignment
• Abutments are un-restored

Question 28

T/F: fixed prosthesis provides better comfort function and security

Answer 28

t

Question 29

What is a cantilevered FDP

Answer 29

bridge with an abutment only on one side

Question 30

Where is the only place in the mouth where a cantelievered bridge should be used

Answer 30

lateral incisors

Question 31

What is the most common failure associated with Maryland bridges

Answer 31

debonding

Question 32

What is todays most used alternative for restoring short edentulous span

Answer 32

implants
