Q

Loose temporary management

A
  • Assess cause of failure
  • Alleviate pain/sensitivity
  • Assess prep:
  • ensure no damage to preparation
  • new impression
  • Clean tooth of cement
  • Fabricate new crown and cement
  • May consider using different technique/stronger cement

Q

Reasons why temporary may be loose

A
  • Inadequate technique for cementation
  • Inadequate quantity/quality of cement
  • Unsuitable occlusion
  • Poor placement technique
  • Poor retention form poorly formed prep

Q

6 functions of temporary

A
  • Protect dentine & pulp
  • Maintain and restore occlusion
  • Maintain marginal integrity
  • Maintain aesthetics
  • Identify under prepared areas or undercuts
  • Easy removal - no damage to prep

Q

3 types of ceramics and how substructure affects

A

• DENTINE BONDED CROWN:
- Minimal tooth prep. Translucent material - very aesthetic.

• PREFORMED METAL CROWN:
- Metal supported with sintered ceramic veneer (1mm) - often opaque appearance and metal margin showing through - least aesthetic

• ALL CERAMIC:
- High strength ceramic substructure often opaque with a sintered ceramic veneer. Heaviest prep of all crowns. Less aesthetic than DBC but more so than PFM, especially with more translucent ceramic sub structures

Q

Dentine bonding precautions

A
  • Moisture control - rubber dam
  • Dry do not desiccate tooth
  • Air dry 5 seconds for even spread of bond
  • Etch for 10 seconds (if on natural tooth)
  • Light cure 15 seconds

16
Q

Optimum outcome after XLA

A
  • Mesial movement of 7 to close the gap and replace 6
  • No distal drifting of the 5
  • No overreaction of opposing 6
  • Normal eruption of 8s with no impaction
  • Control of disease, increase in OH and no caries
  • Positive attitude towards dentistry
17
Q

Problems with early XLA of 6

A
  • Mesial tilting of the 7
  • Mesio-lingual rotation of 7
  • Disturbing of occlsuion (if lower 6 la then upper 6 may overerupt)
  • Loss of anchorage for URA
18
Q

How management changed in Class 2 Div 1

A

Aim = Class 1 molar

2 options:
• Correct class II with XLA and then fit functional appliance
• Retain and incorporate  into ortho tmt plan
  • Don’t extract in lower unless xla in upper otherwise will increase discrepancy
  • If lower molar:
  • Crowded lower arch
  • Not crowded lower arch
  • XLA when bifurcation of the 7s to close space, consider removing upper 6s during tmt

• If upper molar:
- Retain so can be extracted and space can be used during orthodontics

19
Q

RPD - 5 clinical examination features

A
  • Occlusal relationship - guidance
  • FWS
  • Centre line
  • Lip line
  • Restorative and vitality status of teeth
  • Position of teeth present
  • Shape and position of potential abutments
20
Q

Reason for SDA

A
  • No evidence for TMJ problems
  • No detriment from prostheses
  • No need for immaculate OH
21
Q

Chronic atrophic candidosis Causes & Symptoms

A

CAUSES:
• Poor OH

  • Leaving denture in at night
  • Systemic disease - diabetes, xerostomia
  • Excessive FWS - unretentive

SYMPTOMS:
• Red palate in denture bearing areas

  • Some hyper plastic tissue
  • Angular cheilitis
  • Mostly asymptomatic
