Immediate Dentures Flashcards
what is inflammatory papillary hyperplasia and where does it occur
a reactive tissue growth usually developing under a denture
- occurs on hard palate underneath denture base
describe the appearance of IPH
asymptomatic red or pink nodules on mucosa of hard palate and occasionally the residual ridge
IPH is directly related to:
constant wearing of ill fitting denture and poor oral hygiene
with IPH ____ is frequently present
candida
IPH can be related to?
combination syndrome
what are the two protocols for immediate dentures
- conventional: reline the immediate denture after healing and ridge stable (6 months) ONE denture
- interim/transitional: aim is to use for short period, then it is replaced by the definitive prosthesis when healing is complete TWO dentures
when are immediate dentures fabricated
prior to extracting natural teeth
with a conventional/classic immediate denture _____ is done
relining/refitting
with an interim/transitional immediate denture ___ is made
new CD
what are the advantages of the immediate CD
- prevent patient embarassement
- provide guide for optimal esthetics
- provide guide for OVD
what are the disadvantages of immediate dentures
- increased complexity- impressions, CIR
- lack of clinical evaluation of trial denture anterior esthetics
- increased maintenance
- greater number of visits - more costs
what needs to be explained to patients about immediate dentures
- do not fit as well as normal CD
- the pain of the extractions in addition to the sore spots caused by the immediate denture will make the first week or two after insertion difficult
- will be difficult to eat and speak clearly
- the esthetics may be unpredictable because an anterior try in not possible
what are the steps of an immediate denture
- exam/dx/tx plan
- prelim impressions
- secondary impressions
- maxillo-mand relationship records
- posterior trial placement
- extractions - insertion
- post insertion care
what do you look for in the exam and dx
- tori
- tuberosities
- frenal attachments
what is the two phase surgical regimen to maintain RPD abutment teeth
- phase 1: remove posterior teeth, alveoplasty, tuberosity reduction
- fabricate denture
- phase 2: extract anterior teeth at denture insertion appointment
what is phase 1 in immediate CD
- removal of posterior teeth
- surgical correction of tuberosities
- wait 6-8 weeks, begin fabricating the immediate denture
what is phase 2 in immediate CD
- extract anterior teeth
- labial frenectomy if needed
what are the benefits of 2 phase surgery
- simplifies clinical procedures
- reduces post placement care
- improves comfort and retention
what needs to be done at dx
- determine patients expectations
- educate pt about limitations of complete dentures and his/her role in successful outcome
what are the secondary impression techniques
- stock tray
- custom impression tray
- combination
- campagna technique
presence of teeth makes border molding ______
more difficult
in max mand registrations presence of anterior teeth would may OVD determination:
easier
in max mand registrations _______ would make CJR registrations more difficult
malposed, drifted, mobile teeth
with RPD what comes after max mand relations
posterior try in NO anterior try in
