RPD Lecture 10

Question 1

what are types of temporary PRDPs?

Answer 1

interim
transitional
treatment

Question 2

what are interrim RPD indications?

Answer 2

young patients that suffer from post traumatic tooth loss, rapid caries, hereditary partial anodontia

Health: Older patents with compromised medical conditions

TIme: A prosthesis needs to be completed ASAP

Question 3

what are the uses for interim PRDPS?

Answer 3

maintain space
RE ESTABLISH occlusion

replace missing teeth (duh)

Service during perio or implant therapy

Condition patient to their fate of a definitive PRDP

Question 4

what are interim RPDS?

Answer 4

these have wrought/ortho wire, ball clasps

interproximal acrylic struts

surface tension

adhesives

Question 5

describe the hard tissue support for interim?

Answer 5

ball clasps,
wrought/ortho wire rests

cingulum, occlusal rests in acrylic

interproximal, marginal ridge support

Question 6

describe the soft tissue support for Interim?

Answer 6

same as full dentures in distal extension patients
pterygomax notch
retromolar pad and tuberosity coverage

Question 7

this is often used as an immediate replacement for teeth removed during a surgical appointment

Answer 7

interim PRDPs

Question 8

how often should you check stability and replacement of an INTERIM PRDP?

Answer 8

stability and retention should be checked every 3-6 months

soft tissue conditions or chaired reline are essential and needed to compensate for tissue changes as a result of post surgical healing

so interim is like immediate denture?

Question 9

what are transitional RPDS?

Answer 9

used for patient in making that transition to complete dentures

-used to avoid immediate extractions when some or all of the teeth are hopeless, but the patient is not physiologically ready for CDs

teeth are added o the RPD as they’re lost.
relining performed as needed.

no absolute restriction on the use of this prosthesis

Question 10

what are other uses of RPD?

Answer 10

vehicle FOR TISSUE CONDITIONING

• splint to establish a new VDO or occlusal relationship and evaluate the patient’s progress like TMD therapy
• as an occlusal guard to correct or control undesirable oral habits

Question 11

what is the best way to replace a tooth, extend a saddle, change a clasp, repair a broken clasp, add teeth, etc?

Answer 11

make a PICK UP ALGINATE impression.

• pour cast with the PRDP in the impression
• then, remove the PRDP from the cast to make the repairs

Question 12

how to you perform a reline?

Answer 12

RPDP relines are accomplished similar to the CD relines.
K1 and K11 saddles are treated as altered cast impression trays, wash impression is made, rests/clasps engaged.

performa clinical remount to finalize the occlusion

Question 13

what are the 6 reasons for interrims?

Answer 13

1. Sake of appearance
2. Maintenance of a space
3. Reestablishment of occlusal relationships
4. Conditioning of teeth and residual ridges
5. Interim restoration during treatment
6. Conditioning the patient for wearing a prosthesis
