Lecture 1 Intro

Question 1

What is Prosthodontics?

Answer 1

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.

Question 2

Branches of Prosthodontics

Answer 2

1. Fixed Prosthodontics
2. Removable Prosthodontics
   a) Complete Denture Prosthodontics
   b) Partial Denture Prosthodontics
3. Implant Prosthodontics
4. Maxillofacial prosthetics

Question 3

What is the scope of Fixed Prosthodontics?

Answer 3

“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

Question 4

What are Reasons for Tooth Destruction and Loss?

Answer 4

• Caries
• Periodontal disease
• Trauma
• Erosion (GERD)
• Bulemia
• Worn Dentition (Attrition)
• Bruxism

Question 5

What are Reasons for Tooth Destruction and Loss?

Answer 5

• Cysts, malignancies and tumors
• Radiation therapy for tumors
• Grossly mal-aligned teeth
• Iatrogenic extraction
• Congenitally missing teeth
• Failure to erupt (impacted teeth)

Question 6

What is Sequelae of tooth loss?

Answer 6

• 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

Question 7

What is a crown?

Answer 7

a cemented extracoronal restoration covering the

outer surface of a prepared tooth.

Question 8

What factors should be considered when placing a crown?

Answer 8

• “Sleeve” retention
• Slight convergence of opposing walls
• “Path of insertion”

Question 9

What is a Partial Veneer Crown?

Answer 9

an extracoronal restoration

covering a portion of the clinical crown.

Question 10

What factors should be considered when placing a Partial Veneer Crown?

Answer 10

• “Sleeve” retention with additional
internal retentive features
• Grooves

Question 11

What is an Inlay?

Answer 11

• Inlay: a cemented intracoronal restoration is fabricated indirectly and
cemented into the prepared cavity of the tooth.

Question 12

What is “Wedge” retention?

Answer 12

“Wedge” retention: slight divergence of opposing internals walls

Question 13

What is an Onlay?

Answer 13

Onlay: an inlay modified with an occlusal veneer (replacing 1 or more
cusps).

Question 14

What is Fixed Dental Prosthesis (FDP or FPD)?

Answer 14

• Dental prosthesis replacing one or more missing teeth which is
cemented / rigidly attached to remaining teeth (or implants)

Question 15

What are the steps in implant dentistry?

Answer 15

1. Implant is inserted
2. Healing process of the bone (osseointegration)
3. Dental abutment is placed on the dental implant
4. Ceramic crown is placed which replaces the real tooth

Question 16

What are the elements of Fixed Prosthodontics Diagnosis, the Fixed Prosthodontics Work-up?

Answer 16

• Patient History
• TMJ and Occlusal Evaluation
• Intraoral Examination
• Diagnostic Casts
• Diagnostic Waxing
• Custom Trays, Matrix for Interim Restorations
• Radiographic Evaluation
• (Esthetic Analysis)

Question 17

What falls under Patient History?

Answer 17

• Medical History
• Dental History
• Chief Complaint

Question 18

Hodgkins disease / radiation therapy →

Answer 18

Xerostomia

Radiation induced caries

Question 19

What conducting an Intraoral Examination, what do you check for in Periodontal Condition?

Answer 19

• Plaque – where and how
much
• Attached gingiva
• (3mm - abutments)
• Inflammation
• BoP / Pockets
• Gingival architecture
• Mobility

Question 20

When checking the TMJ/Occlusal Evaluation, what do you check for?

Answer 20

• Joints
• Sounds; opening limitations / deviations
• Muscles of mastication
• Palpation of extraoral and intraoral muscles of mastication
• Assessment of pain
• Type and origin of pain

Question 21

What conducting an Intraoral Examination, what do you check for in a Evaluation of Occlusion?

Answer 21

• 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

Question 22

What are Diagnostic Casts?

Answer 22

• Accurate representation of dental arches
• Mounted on a semi-adjustable articulator with a
facebow transfer

Answer 23

occlusal prematurity

intraoral exam / plan for adjustment and results
