Q

What is a Zagg attachment?

A

A zagg attachment is where the ball is not embedded into a HOUSING so that as it wears out you dont have to keep hollowing out the denture itself but just take it out of the housing and replace the ball (the male portion)..minis are better for vertical dimensions

Q

When using a zest atachment and now with an improve housing what is that?

A

a zagg attachment. Make sure to have the patient bite in PASSIVELY and not fully,

Q

will the lttle ball in the tooth cause more or less stress than an rpd with clasps? is that a smaller moment arm?

Q

What is a stud attachmetn?

A

Its a ball and socket type attachment where male (balls) is attached the TOOTH THIS TIME or implant, and female is retained in intaglio of removable prosthesis (so opposite of zest/zagg)

Q

Stress breakers

A

a device that relieves specific dental structure of part of all occlusal forces and redirects those forces to other bearng structure or regions

Q

What does cope mean?

A

To cut end of molding to match the cotour of adjacent piece

18
Q

In dentistry Coping is

A

substructre for fixed dental prosthesis

used for implant level impressions as an impression coping or post

covering or cap made to fit over coronal pt of tooth root

19
Q

Types of copigns

A

crown abd bridge - substructre for fixed dental prosthesis
impresison copings
Copings - male end ball on tooth root or implant

20
Q

types of implant abutment interfaces

A

internal and exrternal hex/bevel, spline, trilobe, morse taper, combo, other

21
Q

SO on stud

A

you replace female end or male and on zest you replace male end.

22
Q

When you are doing your occlusal reduction including your fxn cusp bevel what are the parameters you look at?

A

opposing occlusion, sound tooth structure, tooth anatomy

23
Q

partial coverage is more demanding than full coverage to prep? T / F

A

T

24
Q

Of all the indirect restorations, a gold partial prep is most conservative? T/F

A

T

25
Q

What does a stud overdenture look like?

A

Male with balls ovver tooth or implant, with a zest the ball is in the denture

26
Q

What are the interconnections between abutments and implants?

A

internal and external hex and bevel, spline, combo, trilobe, mores e tapyer, somestimes these are even combined trilobe with internal bevel

27
Q

Of all the interconnections between abutment and implants, which has the fewest pssibly positions?

A

trilobe, from a restoratie standpoint this tends to be more simple.

28
Q

What are the types of coping in dentistry?

A

a coping is covering or cap, metal in PFM is coping, implant coping, compiong assoc with dentures

29
Q

Of all the following for precision attachments whichis best for overdenture>

A

Ball going into matrix hence not stud. Zest is best.

30
Q

What are advantages and disadvantages of extracoronal attachments?

A

Adv: esthetically its better than clasps
disadv: puts alot of load on that tooth, should be a canine.

31
Q

What is a precision attachment?

A

manufactrued male/female component for precise tolerance to hook tooth to dental prosthesis

32
Q

why is it so important to keep taper near ideal with partial coverage gold?

A

You have less axial height and less retention than with full gold crown.

33
Q

what is the primary reason for 360 degree bevel on onlay?

A

it decreases marginal gap,

34
Q

how can you get away with a nonacute angle?

A

easier to finish, and accesible for patient

35
Q

what do you have at your disposal with partial coverage to give you retention and resistance?

A

isthmus, boxes, grooves

36
Q

can you get mesial distal resistance along buccal lingual with isthmus?

A

yes, if you exntend that grooves!

37
Q

with a box form what 2 axial walls are giving you mesial distal resistance

A

the 2 axial walls

38
Q

what do the sides of a box give?

A

buccal and lingual ressitance

39
Q

what do you get from a bevel?

A

mesial and distal resisntace

40
Q

in 3/4 crown what aspect of your retentive frooves compensate for lack of buccal wall?

A

lingual side of that groove

41
Q

what are contrindications forr gold?

A

esthetics, poor oral hygiene, doubtful females
