Whipmix- Celenza Class 3B, semi adjustable
Will accept an arbitrary facebow, and most lateral records (condylar/bennett angle)

helps reproduce simulated mand movement and resembles the anatomic structure of the pt.

23
Q

For an RPD- what teeth would i choose and why?

A

20 degree Portrait IPN
WHY: strong resin resists abrasion, balance of esthetics and function/chewing effeciency/cusp height, easy to adjust

24
Q

When deliverying an RPD or CD, what do i do during the try in phase?

A

Verify occlusion and adjust as needed
Check and verify esthetics with the patient- natural light/light they are in most often

Phonetics-
P,B,M: Bilabial- lip support, A-P position, flange thickness VDO/lip closure
F V: labial dental- incisors in the post 1/3 of lip, too short max V=F, long max F=v
Th: 3mm tongue tip visible(unless class II div I) if not visible, teeth too forward
T,D: T=D if max too L, D=T is max too facial.
S (silibants): opening too small or post arch too narrow=whistle, Opening too big, lisp
OR: is S on mand–> whistle = mand too L, Faulty S, L flange too thick.
SCZ: too gret a VDO= teeth come together.

25
Q

occlusal scheme: Why would I choose a mutually protected occlusion-

A

ideal
ant teeth protected during MIP
Post teeth protected during excursive
THUS: protecting my restore and improving overall prognosis of all definitive tx

26
Q

occlusal scheme: Why would i choose group function?

A

if unable to have Mutually protected due to loss of cainine
done to distribute forces to as many teeth as possible

27
Q

Why would i restore the pt in CO?

A

restoring multiple post teeth bilaterally on both arches
preparing teeth that act as 1st content
CO is most repeatable which helps the lab too

28
Q

Why would I restore someone in MI

A

pt has stable occlusion in the post
(instability = hypermobility, excessive wear, migration of teeth, TMJ pain)

29
Q

Diagnositic: What articulator do i use? and why?

A

Whip Mix Class IIIb- Arcon, smi adjustable, accepts arbitray facebow and lateral records, and I guide table fabrication

30
Q

What facebow do i use and why?

A

arbitrary- Nasion for whipmix is external
related max cast to condylar hinge axis

31
Q

What amalgam do i use and why?

good condensability, ease to develop interprox contacts, good compressive strength, long hx of success.

or Spherical- Tytin
occlusal best, fast setting time, 608mPa @ 24 hr compressive

32
Q

What composite do i use and why?

A

*Nanocomposite- Filtek supreme
-nanoclusters (zirconia/silica or silica nanomer sized particles) clusters are silate treated and crosslink to resins, broad filler distribution.

Microfill-Venus
Esthetic, good polishability, lower MOE, flexes with the tooth Wears well. Use in class 3 or 5 only

33

Primer in optibond: IDK
Common: HMEA, Polyalkenoic acid, aceton, ethanol, PENTA, water

35
Q

What are common adhesives in bond?

A

Bis-GMA, HEMA/UDMA

36
Q

Why might you use a 6th gen, and what is it and give an exampl

A

Because there is not etch, can use for deeper restorations to decrease sensitivity. no post conditioning rinse
6th gen: P and cond then adhesive, 2 step (no etch, or selective etch)
moderately high bond strengths.
Clearfil SE, Optibond XTR

37
Q

What is glass ionomer, which one do i use and why?
How does GI bon?

A

Fuji II LC: dual cure, excellent retention to dentin (similar strength and CTE as dentin), moderate esthetics, fl release and recharge. Use on Class 5 lesions in high caries risk pt.

Bond: A/B rxn polyacrylic acid is the conditioner, 20 secs, remove smear

EQUIA Forte HT - hybrid filler is more susceptible to moisture and temperature cycling. Fuji II LC exhibits a smoother surface with reduced cracks, voids, and clumps compared to EQUIA Forte with and without a resin coating.

38

Endo activator use in canal

Continous wave- set plugger to 5-7mm from apex. Back fill and plug. Permaflow purple over orifice.

Use MTA for perfs or other probelms.
Close access- depends on plan with tooth.

39
Q

What do i use for ridge preservation after ext?
