Intro to Fixed I Flashcards
What are the categories included in prosthodontics?
- Fixed prosthodontics
- Removable prosthodontics (complete or partial)
- Implant prosthodontics
- Maxillofacial prosthodontics
Prosthodontics is a body of knowledge and skills pertaining to the _____ & ____ of the natural dentition with artificial substitutes
restoration & replacement
Prosthodontics is a body of knowledge and skills pertaining to the restoration of the dental arches with ____ or ____ dental prosthesis
Fixed or removable
The branch of prosthodontics concerned with the replacement and/or restoration of teeth by artificial substitutes that cannot be removed from the mouth by the patient:
Fixed prosthodontics
Fixed prosthodontics is mainly comprised of: (4)
- crowns
- bridges
- implant crowns
- full arch implant supported denture
What are we trying to accomplish with fixed prosthodontics?
- restore:
- replace:
- improve:
- complete, improve or maintain:
- _________ improvement
- function and esthetics of single teeth
- missing teeth
- comfort and chewing
- the integrity of dental arches
- patient self-image
Prior to beginning any fixed prosthodontic work, its important to understand the patients:
current total oral & systemic condition
What should be completed prior to any fixed prosthodontic work? (7)
- Patient medical and dental history
- Occlusal/TMJ evaluation
- Intraoral/Periodontal exam
- Radiographic evaluation
- Mounted diagnostic casts
- Caries risk assessment
- Patient expectations
Includes any systemic conditions such as xerostomia which could affect the longevity of your dental work:
Medical & dental history
-Is the patient’s occlusion healthy?
-Is canine guidance present?
-Is group function present?
-Are there occlusal interferences?
-Is the bite collapsed?
These questions are all determined during:
Occlusal evaluation
What should be noted when performing the intraoral exam prior to starting the fixed prosthodontic work?
- plaque accumulation
- home care
- tissue abnormalities
What should be noted when performing the periodontal exam prior to starting any fixed prosthodontic work?
- home care
- is periodontal disease present (if so is it stable)
- tooth mobility
When evaluating radiographs prior to starting fixed prosthodontic work, you should look for: (6)
- bone loss
- PARL
- Crown to root ratio
- Location of pulp chamber
- Endodontic issues
- Are these teeth potential candidates for fixed work
-Allow for planning and visibility outside the patient mouth
-Can be used for diagnostic wax up to predict treatment outcomes
-Allow for patient education
Mounted casts
The amount of ______ in the patients past and present impacts the treatment you deliver
caries
High caries risk means high risk of ________ around ______
Recurrent decay; crown margins
What is an important question to ask prior to starting any fixed prosthodontic work?
(regarding current damage)
How did the patients teeth get diseased or missing?
(Examples: impaction, extraction, tumors, caries, cancers, trauma, abrasion, erosion, bruxism, malalignment, periodontal disease, radiation therapy cysts, congenitally missing)
Prior to prosthodontic work, what should you consider about patient expectations?
- are they reasonable
- are they achievable
- are they realistic
- what would it take to meet those expectations & are you able to do so
a cemented extra-coronal restoration covering the outer surface of a prepared tooth:
Dental crown
The #1 reason we put a crown on a tooth is to:
Strengthen the tooth
A tooth is prepared for a full coverage crown with criteria in order to create:
- “sleeve” retention
- a path of insertion
- a slight convergence of the walls of the tooth preparation to allow for seating of the crown
In addition to single crowns, other types of fixed restorations include: (5)
- 3/4 crown
- inlay
- onlay
- fixed dental prosthesis (bridge)
- implant crowns
A cemented intra-coronal restoration fabricated indirectly:
Inlay
An inlay also replacing one or more cusps:
onlay
Crown replacing one or more missing teeth which is cemented to remaining teeth or implants:
Fixed dental prosthesis (bridge)
