Prosthodontics

Part A: Removable Partial Denture

Part B: Removable Complete Denture



Learning Objectives1. Define the Key Terms.

2. Explain the reasons for removable

prostheses.

3. List the components of a partial denture.

4. Describe the consultation appointment for a removable prosthesis.

5. Explain the difference between a removable partial and a complete denture.



Learning Objectives6. Describe the appointment steps for a partial

denture and a complete denture.7. Explain denture reline, repair, and adjustment

procedures.8. Demonstrate partial denture final impressions

and delivery.9. Demonstrate a jaw relationship and a denture

relining procedure.


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

Study models

Photographs

Visual aids

Radiographs

Treatment plan

Consultation appointment


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


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


Components of a Partial Denture


Metal Frameworks


Appointments for a Partial Denture

Partial Denture

Exam

Consultation

Final impressions

Try-in and adjustment

Delivery

Part B: Removable Complete Denture

• Edentulous patient

• Denture supported by alveolar bone and oral mucosa


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


Components of a Complete Denture

First follow-up

Adjustments


Final Impressions

• Impression compound

• Border molding

• Muscle trimming


Construction of Complete Dentures

• Baseplate– Represents

denture base

• Bite rim– Simulates space

provided by height of teeth

• Vertical dimension– Occlusal

relationship


Jaw Relationship Set-up

• Baseplates and bite rims

• Centric occlusion– Retrusion– Protrusion– Lateral movement

• Vertical dimension• Shade• Mold


Try-in Appointment

• Denture teeth mounted in wax

• Evaluate– Esthetics– Retention– Comfort– Speech articulation


Delivery Appointment

• Immediate dentures– Extractions and

alveoplasty

• Evaluation• Adjustments• Instructions

– Insertion and removal– Daily maintenance


Denture Relines, Adjustments, and Repairs


Implants and Overdentures

Advantages

Disadvantages


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.


Summary of Module

• Key Terms• Types of fixed prosthetics and materials• Procedures performed during fixed and

removable prosthodontics• Considerations for fixed crowns and bridges,

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

relines, and adjustments
