removable prosthodontics Flashcards
What four types of dentures are there?
partial upper denture
Complete upper denture
Partial lower denture
Complete lower denture
two types of removable prosthodontics
removable partial denture
Removable full denture
six extraoral factors for selecting, removable prosthodontics
1) physical health
2) mental health
3) motivation
4) age
5) dietary habits
6) occupation in social and economic factors
what area of your physical health impacts the selection of removable prosthesis?
If your tissues cannot withstand the pressure or patient cannot cooperative during segregation in Centre
How does your mental health affect? The selection of removal processes is
Patient might not be able to keep processes in mouth organ have a lack of adequate oral hygiene
What tooth would you never replace?
Third molar
How does motivation impact selection of removable prosthesis?
Lack of motivation to clean teeth would damage aesthetics
how does age impact the selection of removable prosthesis
-A young patient there’s still growth
-Activation process must be strong
-Old patient might want to return to that should be extracted resulting in an unstable environment
how does dietary habits affect the selection of removable prosthesis
Poor nutrition can cause portage she responds that may affect tolerance and comfort
How would occupation and social, and economic factors affect the selection of removable prosthesis
Public person might want to have something fixed as so the teeth don’t fall out as well as cost and lack of patient understanding
Clearance
Removal of all teeth
seven intraoral factors that may affect the selection of removable prosthesis
musculature
Salivary flow
Residual alveolar ridge
Oral mucosa
Aural habits
Tori
Are Howard musculature affect the selection of removable prosthesis
Facial muscles provide retention and control meaning that facial spasms can cause denture to lose its suction, as well as a large tongue can impact suction
How is salivary flow affect a selection of removable prosthesis
too much saliva can be produced when a prosthesis is introduced
Xerostomia can make a prosthesis difficult to wear
How does a residual alveolar ridge affect the selection of removable prosthesis
If the patient has a resorbed, uneven, residual, alveolar ridge, there’s bad support and often patient discomfort and alveoplasty may have to be performed
How does oral mucosa affect the selection of removable prosthesis?
Sore spots are pressure points may develop on the tissue that has altered by the patient physical condition
how does a patient oral habits affect the selection of removable prosthesis
bruxism or clenching can cause stress on the alveolar ridge and the remaining teeth
Someone who is termed, a mouth breather, might not be able to retain a prosthesis in the mouth
how does Tori affect the selection of a removable prosthesis?
May get in the way and have to be removed before fabrication of the processes
Clasps
Help to hold the teeth intact
edentulous
Patient has no teeth
Components of a full denture
base
Flange
Post dam
Artificial teeth
indications for a full denture
-Patient is edentulous
-remaining teeth cannot be saved -remaining teeth cannot support a removable, partial denture, and no acceptable alternatives are available
-Patient refuses alternative treatment
contradictions for a full denture
Acceptable alternative is available
Bad physical or mental health
patient is hypersensitive to denture materials
Patient is not interested in fixing remaining teeth
Base of a full denture
Designed to fit over the residual, alveolar ridge and surrounding gingival area
Flange
Part of the base of extends over the attached, because it from circle margin of the teeth to the border of the denture
Post dam
retention of a maxillary denture, depends on the suction seal
Artificial teeth
Fabricated from acrylic or porcelain
Retromolar pad
Area just behind the third mandibular molars
fovea Palatinata
Small hole on the pallet that indicates the end of the denture area
posterior Palatal seal
Line between the hard palate in the soft palate
What is another name for the posterior palatal seal?
Ah line
Five components of a partial denture
framework
Connecters
Rests
Retainers
Artificial teeth
What is the framework of a partial denture?
A cast metal skeleton that provide support for other components of the denture, usually covered with acrylic to simulate appearance of the tissue
Connecters of a partial denture
join parts of the person that shit together
Two types: major connecter and minor connecter
Major connecter
Metal bar that joins right left quadrant framework
minor connecter
Attaches major, connected to the base, rests and clasps
rest
Metal projection from the framework, extending to the prepared tooth controls the setting of the prosthesis
Two types of rests
lingual
occlusal
retainer/clasps
support and stablizes the denture
Two types of retainers on a fixture partial denture
I-bar
circumferential (c) clasp
denture base on a partial denture
The part of the denture that rests on the foundation tissues to watch the teeth are attached
two types of artificial teeth
acrylic
porcelain
3 removable partial denture requirements
support
Stability
Retention
3 things to consider when selecting anterior teeth
shade
Shape
Size
Denture realigning
Placing a new layer of denture resin over the tissue surface of the prosthesis
How long will it a patient have to be without a denture for a denture realigning
8-24 hours
reline indication
Loss of attention
Instability
Food under denture
Abused mucosa
Discomfort and pain, while wearing the denture
contradictions for reline
worn out dentures
Vertical dimension loss greater than 7 mm
Significant mucosal information
Denture related speech problems
tissue conditioning
Before the real line can be done, the tissue has to be restored to the healthy state using tissue conditioner
indications for tissue conditioning
Discomfort
Abused tissue
Lots of vertical dimensions
Lack of attention
Lifespan of tissue conditioner
2-3 weeks
when is the maximum cushioning effect of a tissue conditioner achieved
3-4 days
how long do you keep conditioner in
1-3 weeks
CUD reline
place ZOE wash and have patient close in centric postion
denture rebasing
The process of refitting a denture by replacing the denture base material without changing the occlusal relations of the teeth
Denture duplication
Making a spare denture just in case it breaks must be kept in moist airtight container
Immediate dentures
Type of denture placed immediately after the extraction of a patient from anterior teeth
Indications for immediate denture
multiple extractions
what arch will you mainly put an immediate denture on
maxillary
Conventional, immediate complete dentures
used after you have removed all posterior teeth about three months before making immediate denture to allow for posterior segment to heal and stabilize
over denture
A Full denture, supported by bony ridge oral mucosa in two or more remaining teeth
long coping technique
minimal of the tooth is removed they are protected with coping and the dentures is fitted on top of them
implant retained dentures
the implants are used to facilitate retention, stability, and provide support to the anterior region
short coping technique
used on endodontically treated teeth or if implant is done
the tooth surface is greatly reduced and shortened and protected with a coping
coping
metal piece that clicks onto the denture
implant supported denture
all occlusal forces are borne with by the implants
