Q

How does ICP differ from RCP?

A

Requires index teeth
Stable occlusion
May vary through life
Depends on tooth relationships
Typically more anterior than RCP

Q

How does RCP differ from ICP?

A

Is a condylar position
Typically more posterior than ICP

Q

What does the term conforming to occlusion mean?

A

Works best in a stable occlusion with sufficient index teeth.

We aren’t changing the current occlusion, and our prosthesis isn’t altering the occlusion.

Q

When is changing the occlusion indicated?

A

When there is a lack of sufficient index teeth

Often use RCP as its reproduceable.

Occlusion may be more challenging to record.

A

Crown
Abutment
Titanium implant

23
Q

What can dental implants restore?

A

Multiple teeth
Can secure a denture

24

Raise flap
Place implant
Place cover screw
Suture

25
Q

Outline the broad steps for implant restoration?

A

Expose implant
Place abutment

Gold bar
CAD-CAM titanium bar

27
Q

List FOUR common post implant treatment complications.

A

Peri-implant mucositis
Peri-implantitis
Loose/fractured components
Late implant failure

28
Q

What is the role of the GDP in managing implant patients?

A

OHI
Triage and diagnosis of complications
Referral to specialists

29
Q

What is required for maintenance of dental implants?

A

Optimal plaque removal around implants

Monitor peri-implant tissues

Perform radiographs when clinically indicated.

30
Q

Should implants be used for BPE?

A

No, however their own probing depths should be monitored.

31
Q

What is peri-implant mucositis?

A

Inflammation around the implant with no crestal bone loss.

32
Q

What is peri-implantitis?

A

Inflammation with suppuration around the implant, with significant crestal bone loss.

33
Q

How can you perform PMPR on an implant?

A

Hand scaling
Ultrasonic with specialised tips

34
Q

What is the consequence of using standard ultrasonic tips on implants?

A

Can damage the coating of the implant

Can cause cementation of crown to fail

Can disturb osteointegration

35
Q

What is retchinng?

A

Physiological mechanism
Involuntary contraction of the soft palate or pharynx
Modified by medulla oblongata

36
Q

What are the main types of retching?

A

Psychogenic (Sight, smell, sound, thought)

Somatic (Touching of trigger zones)

37
Q

What problems does retching pose in pros?

A

Impression taking issues
Jaw reg issues
Toleration of dentures
Denture retention issues

38
Q

How do you manage retching?

A

Identification of problem
Identify trigger zones
Anxiety reduction
Patients and empathy

39
Q

Describe some distraction techniques for managing retching in a patient?

A

Talking to them
Concentrate on raising leg/wiggling toes
Tap their temple
Close eyes
Salt on tongue

40
Q

Describe some desensitization techniques for managing a patient with retching?

A

Repeated stroking of anterior palate with finger
Homework of brushing their palate
Swallowing with mouth open

41
Q

What aspects of denture design can be altered to help a patient who retches?

A

Thin palatal coverage
Multiple post dams to cut back if needed
Cusps can be rounded to not stimulate tongue
Consider no 2nd molars
Horseshoe plate

42
Q

What is the rough proportion of people who are dissatisfied with their dentures?

A

10-30%

43
Q

What are the main reasons a patient is dissatisfied with their denture?

A

Retention and stability
Tends to be lowers more than uppers
Tends to be partials more than completes

44
Q

What aspects of a patients oral biology may impact denture success?

A

Severely resorbed ridges
Flabby ridges
Tori
Prominent mentalist muscles
High muscle attachments
Pain on ridge palpations
