Key Terms

• Abutment• Anatomical• Baseplate• Bite rim• Border molding• Centric occlusion• Connectors• Denture base• Framework

• Muscle trimming• Non-anatomical• Overdenture• Partial dentures• Prostheses• Relined• Rests• Retainer• Vertical dimension

Part A: Removable Partial Dentures

• Replaces one or more teeth in one arch

• Retained and supported by underlying tissues and remaining teeth

Advantages of a Removable Partial

Less expensive than fixed

prostheses

Proper occlusal plane is

maintained

Fewer intraoral procedures

than fixed pros.

May support periodontally

involved teeth

Stabilizes the arches

Restores function when

no distal teeth present

Restores

long span

of lost

dentition

Easier for good oral hygiene of

abutments

Easily repaired and adjusted

6

Contraindications for a Partial

Lack of sufficient number of naturalteeth properly located in the arch

Lack of teeth with adequate rootsupport to retain the appliance

Rampant caries or gross periodontalconditions of remaining teeth

Poor oral hygiene with no motivationto improve oral conditions

Part B: Removable Complete Denture

• Edentulous patient

• Denture supported by alveolar bone and oral mucosa

11

Indications for a Complete Denture

Lack of financial resources for

alternative treatments

Patient refused partial dentures

Edentulous patient

Gross decay or abscesses

Lack of motivation or

ability to maintain teeth

Extensive bone loss and

periodontal disease

14

Final Impressions

• Impression compound

• Border molding

• Muscle trimming

15

Construction of Complete Dentures

• Baseplate– Represents

denture base

• Bite rim– Simulates space

provided by height of teeth

• Vertical dimension– Occlusal

relationship

16

Jaw Relationship Set-up

• Baseplates and bite rims

• Centric occlusion– Retrusion– Protrusion– Lateral movement

• Vertical dimension• Shade• Mold

17

Try-in Appointment

• Denture teeth mounted in wax

• Evaluate– Esthetics– Retention– Comfort– Speech articulation

18

Delivery Appointment

• Immediate dentures– Extractions and

alveoplasty

• Evaluation

• Adjustments

• Instructions– Insertion and

removal– Daily maintenance

19

Denture Relines, Adjustments, and Repairs

20

Assessment Questions

• What does the bite rim simulate?

Vertical dimension, or the height of the teeth.

• What is the term for not having any teeth?

Edentulous.• What happens to the bone following tooth

extractions?

The bone will shrink and resorb.

removable prosthodontics• Considerations for fixed crowns and bridges,

partial dentures, and complete dentures• Construction of prostheses• Partial and complete denture components

relines, and adjustments
