Lecture 1 Intro Flashcards
What is Prosthodontics?
Prosthodontics is that body of knowledge and skills pertaining to:
• The restoration and replacement of the natural dentition with
artificial substitutes.
• The restoration of the dental arches with fixed or removable
dental prostheses.
Branches of Prosthodontics
- Fixed Prosthodontics
- Removable Prosthodontics
a) Complete Denture Prosthodontics
b) Partial Denture Prosthodontics - Implant Prosthodontics
- Maxillofacial prosthetics
What is the scope of Fixed Prosthodontics?
“Restoration of a single tooth to rehabilitation of the entire occlusion”
• Restore function and esthetics of single teeth
• Replacement of missing teeth
• Improve comfort and mastication
• Complete / maintain the integrity of dental arches
• Self image
What are Reasons for Tooth Destruction and Loss?
- Caries
- Periodontal disease
- Trauma
- Erosion (GERD)
- Bulemia
- Worn Dentition (Attrition)
- Bruxism
What are Reasons for Tooth Destruction and Loss?
- Cysts, malignancies and tumors
- Radiation therapy for tumors
- Grossly mal-aligned teeth
- Iatrogenic extraction
- Congenitally missing teeth
- Failure to erupt (impacted teeth)
What is Sequelae of tooth loss?
• Resorption: The socket remodels until it assumes the shape of the rounded edentulous ridge. • Tilting • Drifting • Occlusal disharmony: leads to discomfort, pain or damage to TMJ
What is a crown?
a cemented extracoronal restoration covering the
outer surface of a prepared tooth.
What factors should be considered when placing a crown?
- “Sleeve” retention
- Slight convergence of opposing walls
- “Path of insertion”
What is a Partial Veneer Crown?
an extracoronal restoration
covering a portion of the clinical crown.
What factors should be considered when placing a Partial Veneer Crown?
• “Sleeve” retention with additional
internal retentive features
• Grooves
What is an Inlay?
• Inlay: a cemented intracoronal restoration is fabricated indirectly and
cemented into the prepared cavity of the tooth.
What is “Wedge” retention?
“Wedge” retention: slight divergence of opposing internals walls
What is an Onlay?
Onlay: an inlay modified with an occlusal veneer (replacing 1 or more
cusps).
What is Fixed Dental Prosthesis (FDP or FPD)?
• Dental prosthesis replacing one or more missing teeth which is
cemented / rigidly attached to remaining teeth (or implants)
What are the steps in implant dentistry?
- Implant is inserted
- Healing process of the bone (osseointegration)
- Dental abutment is placed on the dental implant
- Ceramic crown is placed which replaces the real tooth
What are the elements of Fixed Prosthodontics Diagnosis, the Fixed Prosthodontics Work-up?
- Patient History
- TMJ and Occlusal Evaluation
- Intraoral Examination
- Diagnostic Casts
- Diagnostic Waxing
- Custom Trays, Matrix for Interim Restorations
- Radiographic Evaluation
- (Esthetic Analysis)
What falls under Patient History?
- Medical History
- Dental History
- Chief Complaint
Hodgkins disease / radiation therapy →
Xerostomia
Radiation induced caries
What conducting an Intraoral Examination, what do you check for in Periodontal Condition?
• Plaque – where and how much • Attached gingiva • (3mm - abutments) • Inflammation • BoP / Pockets • Gingival architecture • Mobility
When checking the TMJ/Occlusal Evaluation, what do you check for?
- Joints
- Sounds; opening limitations / deviations
- Muscles of mastication
- Palpation of extraoral and intraoral muscles of mastication
- Assessment of pain
- Type and origin of pain
What conducting an Intraoral Examination, what do you check for in a Evaluation of Occlusion?
• Presence and location of caries • Previous restorations and prostheses • Evaluation of the occlusion • Relationship of spaces, if more than one • Bony defects • Health of tissues • Wear facets • Occlusal prematurities; interferences; buttressing bone • Difference between CRCP (CO) and MIP • Existence and amount of anterior guidance • Occlusal Scheme • Canine Guidance • Group Function • Bilateral Balance
What are Diagnostic Casts?
• Accurate representation of dental arches
• Mounted on a semi-adjustable articulator with a
facebow transfer
Diagnostic Casts confirm…
occlusal prematurity
intraoral exam / plan for adjustment and results
Diagnostic casts provide…
information for diagnosing
problems and arriving at a treatment plan
