ERIN TEMP RELINES Flashcards
what are the indications for an INTERIM?
-young patients, post traumatic tooth loss, caries, etc.
-Health: Older adult patients with compromised medical conditions.
TIME-ASAP
what are the uses of interim?
- maintain a space
- reestablish occlusion
- replace those missing teeth
- service during PERIO OR IMPLANT therapy
- condition patient to definitive PRDP
describe the design principles for interim?
retnetion is with wrought/orhto wire, ball clasps
- interprox acrylic struts
- surface tension
- adhesives
- NOT ALL CASES need clasps-sometimes acrylic retention is fine
describe the hard tissue support f r interim?
- ball clasps (inter proximal, marginal ridge support)-
- wrought/ortho wire rests
- Cingulum, occlusal rests in acrylic
describe the soft tissue support for interim?
these are the same as full dentures in distal extension patients
- pterygomax notch extension
- retromolar pad, tuberosity coverage
are the cingulum and occlusal rests of interim in metal or acrylic?
they’re in ACRYLIC!
how often should you check the interim appliances?
every 3-6 months
what is necessary to compensate for the tissue changes as a result of post surgical healing?
soft tissue conditioners or hard chaired reline materials
what are the indications for transitional RPDs?
to aid a patient in making the TRANSITION to complete dentures.
- to avoid immediate extractions when some or all of the teeth are hopeless but patient not ready for CD
- NO ABSOLUTE time restrictor on the use of these.
- THESE can be worn longer than INTERIM
what are TREATMENT PRDPS?
these are used as a vehicle for TISSUE CONDITIONING
-also could be used as a treating splint to establish NEW VDO or occlusal relationship (TMD therapy)
an occlusal guar d to control undesireable oral habits
what’s the best method for PRDP repairs?
PICK UP ALGINATE impression and pour cast WITH THE PRDP in the impression
-The PRDP is removed from cast to make the repairs.
can there be an all resin partial?
no, you have to have wire rests somewhere?
what does intracoronal mean?
a retainer WITHIN THE CROWN.
describe intracoronal retainer?
-precision attachments and semi precision attachments.
usually made with male and female, with PARALLEL walls within contours of a restoration, creating frictional resistance against the displacement of the PRDP. Can have a crown with cast keyway attachment.
describe extracoronal?
this means OUTSIDE OF THE CONTOURS of the abutment
- you have attachments
- retentive clasp arms
- you create MECHANICAL resistance to displacement through the external surface of an abutment tooth
