RPD Flashcards
(16 cards)
Define prosthetics
A replacement for a missing part of the body
Define prosthdontics
Branch of dentistry pertaining to the restoration and maintenance of oral function, comfofort, appearance, and health
Define prosthesis
An artificial replacement of a missing part of the body
Define RPD
Removable partial denture - a dental prosthesis designed to replace some (not all) of the teeth in a an arch of a partially edentulous patient. They distribute forces onto remaining soft and hard tissues in a easily placed/removable fashion
What is the purpose of an RPD?
three points
To improve or restore:
- Function
- Esthetics
- Phonetics
RPDs are required to distribution occlusal forces over….
as broad a surface as possible. Which may or may not include hard tissue
Eight stages required to provide an RPD
- Planning (the proper dx of which teeth to replace)
- Design of partial denture
- Pre-prosthetic treatment (periodontal tx)
- Tooth modification
- Framework fabrication
- Capture of supporting soft tissue
- Reconstructing the missing tissues
- Delivery and maintenance (you need tissue to remain healthy to avoid pulling teeth and loosening RPD)
Planning is a critical step which consists of (2)?
- oral/radiographic examination
- Preliminary impression
RPD are often first choice for?
RPD are often first choice for medically compromised patients. They are less invasive then fixed partial dentures or bridges
Cons to RPD (4)
- Trap plaque
- Difficult to clean
- Requires adaptation
- May complicate exisiting oral conditions
The 4 psychological profiles:
- Philosophical
- Exacting
- Hysterical
- Indifferent
Define philosophical profile
easy going, well adjusted patients involved in their oral care. They take responsibility for situation
most IDEAL patient who will tolerate well made prosthesis
Define exacting profile
Precise, perfectionist and demanding. These are difficult patients with high expectations who will require extra time. They must be warned of possible problems BEFORE they occur, and be given lots of attention (if you please them, they are great ambassadors)
Define hysterical profile
Apprehensive and complain without reason. Do not accept responsibility for their problems. * If attitudes cant be changed these patients will fail no matter what.*
Define indifferent profile
Unmotivated , unconcerned, uncooperative, ignore instructions, and show little concern for oral health. Poor prognosis unless attitudes change - RPD will end up causing harm
Systemic diseases that affect dental treament (8)
- DIABETES - poor tissue tone, abscesses, and reduced saliva. They have increased caries and difficult adaptation
- ARTHRITIS - Changes in TMJ (occlusion changes, difficulty determining centric relation)
- PAGET’S DISEASE - continued enlarment of maxillary tuberosities causing changes in fit and occlusions (more recalls required).
- ACROMEGALY - mandibular enlargement requires frequent examination for fit and function
- PARKINSON’S - rhythmic muscular contraction may cause difficulty to insert RPD and care for prosthesis (oral hygiene).
- PEMPHIGOUS VULGARIS - bullae in oral cavity, oral discomfort and dryness is erroneously linked to RPD but once diagnosed, no problems with RPD if maintained
- EPILEPSY - frequent seizures without warning make this CONTRAINDICATED, otherwise use radiopaque RPD and prevent drug induced gingival hyperplasia by using smooth polished borders on RPD
- CANCER - side effect of treatment can cause xerostomia, infections, mucosal irritation (difficulties arise with RPD)
