Removable Prosthodontics Flashcards
Week 3/4
In this specialty of dentistry, missing teeth are replaced with implants or removable prostheses
removable prosthodontics
a prosthesis that closes an opening or communication between the nasal and oral cavity
obturator
if a removable dental prosthesis is designed for a patient who has undergone oral cancer surgery, it also may need to function as an __________.
obturator
intraoral factors for a removable prosthodontics
musculature
salivary flow
residual alveolar ridge oral mucosa
oral habits
tori
aids in denture retention and function
normal salivary flow
extraoral factors for removable prosthodontics
physical health mental health
age
diet
socioeconomic status occupation
Temporary replacement for missing teeth in a child
Flipper
contraindications for removal partial denture
lack of suitable teeth
rampant caries / severe
lack of patient acceptance
components of a partial denture
framework
connecters
retainer
rest
artificial teeth
connector that Joins the right-and-left-quadrant framework of a partial denture and helps support the remaining teeth
major connector
metal device built into a partial denture design to protect the abutment teeth from excessive occlusal loads and stress during mastication.
stress breaker
Which connector is used for the clasps and rests?
Minor connectors are used
What are the drawbacks of porcelain teeth?
they produce clicking sounds and fracture easily
drawbacks of acrylic teeth
wear faster
more susceptible to staining
metal projection designed to control the seating of the prosthesis-usually on occlusals- notch drilled out of teeth
rest
What type of material is used to take the final impression for prep of partial denture?
elastomeric material
during the delivery of partial denture, what are the “pressure points”
where the acrylic rubs on the patient’s tissue
how can the “pressure points” be relieved during the checking of occlusion with partial denture
acrylic bur
component of a full denture designed to fit over the alveolar ridge and surrounding gingival area-usually acrylic with metal frame embedded. Sometime metal frame only
base
component of a full denture BASE that extends over the attached mucosa from the cervical margin of the teeth to the border of the denture
flange
Where is the flange located on a mandibular denture?
extends over the residual ridge and attached mucosa, down to the oblique ridge and mylohyoid ridge, and over the genial tubercles and retromolar pads.
Where is the flange located on a maxillary denture?
extends beyond the residual ridge and over the attached mucosa to the tuberosities and the junction of the hard and soft palates
retention of a maxillary denture depends on the…
posterior palatal seal “suction seal”
retention of mandibular denture depends on the…
support of the remaining alveolar ridge and the suction between the denture and the tissues covering the ridge.
achieving good retention on the mandibular arch is more difficult. True or False
true
achieves closer adaptation of the edges of the impression to the tissues in the mucobuccal fold. Performed after the impression tray is in place
border molding “muscle trimming”
What does vertical dimension refer to?
Space occupied by the height of the teeth in normal occlusion
type of denture is placed immediately after the extraction of a patient’s remaining teeth
immediate denture
A full denture that is supported by the bony ridge and oral mucosa plus two or more remaining natural teeth or implants
Overdentures
With overdentures, the _______ technique is when only a minimal amount of tooth structure is removed, and the length of tooth remains almost the same.
long coping technique
short coping technique
only used with endodontically treated teeth, tooth structure is greatly reduced and shortened
What are the reasons that a denture would need to be relined?
If a denture puts too much pressure on a particular area in the mouth, the area will eventually become sore.
What is the difference between relining and rebasing?
In relining, the prosthesis is resurfaced; in rebasing, the denture base is replaced
Soft liners can precipitate _______ especially on the mandible leading to dentures becoming unretentive
bony ridges resorption
Some edentulous patients develop ____________ as a result of fibrous tissue proliferation after alveolar bone resorption under an ill-fitting prosthesis
denture-induced fibrous hyperplasia
The most common inflammation of the removable dental prosthesis-bearing mucosa
denture stomatitis
topical anti-fungal agent typically prescribed to relieve chronic candidiasis associated with denture.
nystatin
To be effective, topical antifungal agents must be used by the patient for approximately ______ after the disappearance of clinical symptoms.
1 week
mixed bacterial and fungal infection typically caused by Staphylococcus aureus and C. albicans
angular cheilitis
chemical cleansing products for dentures
Alkaline hypochlorite
Alkaline peroxide
anti-microbial cleansers for dentures
chlorhexidine
Ultrasonic
Microwave radiation
