Pros- Patient management

Question 1

What are the four phases of the treatment plan?

Answer 1

1. Immediate treatment
2. Hygenic phase- Changing habits (OH/ smoking cessation) and improving peridontal health
3. Restoration phase- The denture
4. Maintenance-Keep up with the patient & check they are maintaining good oral health.

Question 2

How do we prepare the mouth before we give the patient their new denture

Answer 2

• Deal with the original denture if the patient has it
• Solve problems the patient has
• Periodontal treatment
• Orthodontic treatment
• Fixed prosthetic treatment and endodontics

Question 3

How can we treat patients that have an existing denture?

Answer 3

• Give them a temporary denture (has less bacteria so gives the gum a break)
• Repair or add to the existing denture
• Use a medicated lining to reduce the inflamation
• Adjust the patients occlusion- by adding GI so the patient’s teeth occlude correctly.
• Treat the patient on denture stomatitis ( and educate them that you need to take out your denture at night to prevent this. )

Question 4

How do we get rid of existing oral health problems before giving the patient their denture?

Answer 4

• Radiographs to check
• Remove retained roots and unerrupted teeth
• Remove pathology
• Remove contour on endentulous areas (this reduces bony prominences and hyperplastic soft tissues)

Question 5

What periodontal treatment do we provide for patient’s waiting for a new denture?

Answer 5

We need to know the patient’s periodontal health and if the patient is motivated to clean the device. Then we treat with:

• Oral hygiene instruction
• Scaling and root planing
• Periodontal surgery

Question 6

Why could we use orthodontic treatment on patient’s wanting a denture?

Answer 6

As the orthodontic treatment could improve the space in the patients mouth or the alignment of the patient’s abutment teeth

Question 7

When do we do fixed prosthetic treatments in denture patients and why?

Answer 7

We do them after we have designed the denture but before we make the denture.

This is so we can use the fixed prosthetics to aid the denture such as adding parallel guide planes or rest seats to a crown.

Question 8

When do you prepare the tooth?

Answer 8

Before we create the master casts.

Question 9

How do you prepare rest seats?

Compare Anterior rest seats to posterior rest seats.

Answer 9

Using a slow speed handpeice and cutting into enamel.

Anterior rest seats are cut into the cingulum. Upper rest seats are easier to complete than lowers as uppers have a well defined cingulum.

Posterior rest seats are cut into the marginal ridge.

They should be saucer shape

They have to be deep enough to take a 1mm rest plate.

Question 10

How do you prepare guide planes?

Answer 10

You can only cut 0.5mm of enamel.

But a guide plane should extend 3mm vertically.

Question 11

What are unfavourable surveylines and why are they unfavourable?

Answer 11

Surveylines which are too high.

These are unfavourable as they result in the clasp being placed too close to the occlusal surface which could cause an occlusal interference.

Question 12

How do we prepare the tooth to improve unfavourable surveylines?

Answer 12

We add composite to shape the tooth and produce a lower survey line.
