Q

Why is the hamular notch an important site for complete dentures

A

Site for distal border
Helps with posterior seal
Overextension = pain
Underextension = falls out

Cheap
Easy to use
Elastic

Poor dimensional stability
Not accurate

17
Q

What kind of material is imp compound vs alginate

A

Imp non elastic
Alginate elastic

18

A

SILICONE
Dimensionally stable
Hydrophobic
Variety of consistencies
Messy
V accurate

POLYETHER
Dimensionally stable

19
Q

Compare edentulous vs dentate tray

A

EDENTULOUS = SHALLOW + NON PERFORATED

20
Q

What to mark on denture after primary imp

A

Post dam

21
Q

Lab card for primary imps

A

Please pour up U+L primary imps in 50:50 plaster: stone and construct a light cured acrylic special tray (3mm spacing for alginate)

If silicone/polyether 2mm upper spacing 1mm lower

22
Q

Master imp checks

A

Full coverage of denture bearing area
Full functional depth + width of sulcus
No encroachment on tongue space
Rolled borders
Absence of tears/shine through

23
Q

Lab card for master imps

A

Please pour up U+L master imps in 100% dental stone and provide record blocks on light cured bases for jaw registration

24
Q

What are the record block adjustments to do before LIMBO

A

Stability - rock
Retention - under/OE - frenum, post dam
Support - good mucosal coverage

Adjust anything with wax knife

25
Q

Steps of upper block jaw reg

A

LIIMBO
Lip support
- Nasolabial angle 90-100
- Judge aesthetics + function

Incisal level
- Fricative
- Count from 40-50
- Lick lips + relax
- Ask about show of teeth ideally

Incisal plane
- Foxes bite plane parallel w inter pupillary line
- Mark lipline +high smile line

Midline
- Mark with wax knife

Buccal corridor
- Floss from eye to nose mark that line

Occlusal plane
- Foxes bite plane parallel to alatragal line

Mark post dam say aaaa and located vibrating line

26
Q

Steps of lower block jaw reg

A

Check extensions
Lift tongue/displace
Adjust height to lip level
Midline
Work out FWS

27
Q

How to work out FWS clinically

A

Use willis bite gauge/callipers
RVD - at rest,, say mmmm then relax
OVD - ask pt to bite together

Substrate the RESTING from the OCCLUSAL

28
Q

How do we record occlusion n

A

2 v shaped notches into blocks
Patient in RCP
Adhesive
Bite regi paste
Pick shade + mould

29
Q

Lab card for jaw reg

A

Please mount casts to regi provided on average value articulator and provide a try in
Tooth shade + mould

30
Q

Tooth trial checks

A

OUT OF MOUTH
Trial bases stable on cast
No sharp edges
Extension
Occlusion
AOB/OJ/OB

IN MOUTH
Extension
Retention - pull centrals
Stability - rock
Occlusion
Speech
Aesthetics

31
Q

What is the desired occlusion for a complete denture?

A

Contact on both sides when slide side to side

32
Q

What is the desired occlusion for an RPD

A

Contact on working side

33
Q

Lab card for tooth trial

A

Please prep post dam on casts
Please process in heated cured pMMA

34
Q

How to adjust occlusion at denture delivery stage

A

Selective grinding
BULL RULE
