Week 11 Flashcards
what is a cemented or permanently affixed extra coronal restoration that covers, or veneers, the outer surface of the clinical crown
crown
what is a full coverage or a complete crown that covers the entire clinical crown of a tooth?
full veneer
what can a crown be also referred to as (4)?
full veneer, full coverage, complete crown, or full crown
what can a crown be fabricated of?
- metal (FCC)
- ceramic veneer fuse to metal (PFM or MCC)
- all ceramic material (ACC)
- resin and metal
- resin
what is FCC
full cast crown
what is MCC
metal-ceramic crown
what is ACC
all-ceramic crown
what is a partial coverage crown
3/4, mesial 1/2 and 7/8
what is an all-ceramic thin layer of dental porcelain or cast ceramic that is bonded to one surface of the tooth with an appropriate resin
laminate veneer
what is a prosthetic appliance that is permanently attached to remaining teeth or implants and replaces one or more missing teeth?
fixed partial denture (bridge)
then becomes a FDP (fixed dental prosthesis)
what is FDP
fixed dental prosthesis
what are the 5 components of diagnosis
- health history
- TMJ and occclusal evaluation
- intraoral examination
- diagnostic casts
- full-mouth radiographs
what to look for when examining health history
- medications
- allergies
- cardiovascular disorders
- epilepsy
- diabetes
- xerostomia
- osteonerosis
- current complaint and patient expectations
do we include herbal products when looking at patient meds?
yes
what type of allergies should we show concern for
impression materials, latex and nickel-containing alloys
what are important CVD what we look for?
- BP < 140/90 Hg
- anticoagulants such as coumadin - INR (international normalized ratio)
- IE = infective endocarditis
will we work with patients that have a diastolic reading of greater than 90?
NO
what should we ask for regarding pt diabetes
- HbA1c (how much glucose is tied to RBC)
- hyperglycemia/hypoglycemic episodes
why should we ask pt about diabetes
- healing is generally impaired (circulation issues)
- periodontal breakdown
what can cause xerostomia
- large doses of radiation in oral region
- Lupus erythematosus
- Sjogren’s syndrome
- side effect of numerous drugs
tmj and occlusal evaluation
- joints palpated as pt opens and closes to detect signs of dysfunction
- masseter muscles palpated extraorally by placing the fingers over the lateral surface of rami of mandible
- fingers are placed over patient’s temple to feel temporalis muscles
- index finger used to touch medial pterygoid on inner surface of ramus
- trapezius muscle is felt at base of skull
- SCM grasped between thumb and forefingers
- distance between max and mandibular incisors is measured when patient is open all the way (most people should open at least 1 inch)
- if opening is limited or painful, pt should be instructed to use a finger to indicate the area that hurts
what can we use to protect ourselves from infectious diseases
- rubber gloves
- surgical mask
- eye protection
principles of crown preparation
- preservation of tooth structure
- retention and resistance
- structural durability
- marginal integrity
- preservation of the periodontium
what does it mean to preserve tooth structure
- conserve as much tooth as possible
- must balance with structural durability
